Hello,
this series, targeted for 2.6.34,
- fixes several OMAP clock bugs,
- removes several unnecessary clock structure fields and clock flags,
- splits the OMAP2420 and OMAP2430 clock trees in preparation for
multi-OMAP 2 kernels,
- and modularizes the OMAP3 chip family-specific clock code so
some code and data that is not applicable to a targeted build
can be elided during compilation.
The series has been boot-tested on the OMAP2430 SDP. Further testing
is now being undertaken on OMAP5912 OSK, N800 and OMAP3530 Beagle.
- Paul

* [PATCH 01/13] OMAP2/3/4 clock: fix DPLL multiplier value errors; also copyrights, includes, documentation
2010-02-11 18:16 ` Paul Walmsley

To: linux-omap, linux-arm-kernel; +Cc: Rajendra Nayak, Benoît Cousson
The maximum DPLL multiplier (M) values for OMAP2xxx and OMAP3xxx are
one increment higher than they should be. See for example the
OMAP242x TRM Rev X Section 5.10.6 "Clock Generator Registers" and the
OMAP36xx TRM Rev C Table 3-202 "CM_CLKSEL1_PLL". Programming a 0 into
the DPLL's M register bitfield is valid for OMAP2/3 and indicates that
the DPLL should enter MN-bypass mode. Also, increase the minimum
multiplier (M) value for the DPLL rate rounding code from 1 to 2, to
ensure that it does not inadvertently put the DPLL into bypass.
Note that the register documentation in the OMAP2xxx and OMAP3xxx TRMs
does not make clear that the actual DPLL divider value (the "N") is
the content of the appropriate register bitfield for the N value,
_plus one_. (In other words, an N register bitfield of 0 indicates a
DPLL divider value of 1.) This is only clearly documented in the
OMAP4430 TRM, in, for example, OMAP4430 TRM Rev A Table 3-1167
"CM_CLKSEL_DPLL_USB".
While here, update copyrights, add kerneldoc for struct dpll_data,
drop the unused struct dpll_data.max_tolerance field, remove some
unnecessary #includes in DPLL-related code, and replace the #include
of <linux/module.h> with <linux/list.h>, which is what was really
needed. The OMAP4 clock autogenerator script has been updated
accordingly.

* [PATCH 01/13] OMAP2/3/4 clock: fix DPLL multiplier value errors; also copyrights, includes, documentation
@ 2010-02-11 18:16 ` Paul Walmsley

To: linux-arm-kernel
The maximum DPLL multiplier (M) values for OMAP2xxx and OMAP3xxx are
one increment higher than they should be. See for example the
OMAP242x TRM Rev X Section 5.10.6 "Clock Generator Registers" and the
OMAP36xx TRM Rev C Table 3-202 "CM_CLKSEL1_PLL". Programming a 0 into
the DPLL's M register bitfield is valid for OMAP2/3 and indicates that
the DPLL should enter MN-bypass mode. Also, increase the minimum
multiplier (M) value for the DPLL rate rounding code from 1 to 2, to
ensure that it does not inadvertently put the DPLL into bypass.
Note that the register documentation in the OMAP2xxx and OMAP3xxx TRMs
does not make clear that the actual DPLL divider value (the "N") is
the content of the appropriate register bitfield for the N value,
_plus one_. (In other words, an N register bitfield of 0 indicates a
DPLL divider value of 1.) This is only clearly documented in the
OMAP4430 TRM, in, for example, OMAP4430 TRM Rev A Table 3-1167
"CM_CLKSEL_DPLL_USB".
While here, update copyrights, add kerneldoc for struct dpll_data,
drop the unused struct dpll_data.max_tolerance field, remove some
unnecessary #includes in DPLL-related code, and replace the #include
of <linux/module.h> with <linux/list.h>, which is what was really
needed. The OMAP4 clock autogenerator script has been updated
accordingly.

* [PATCH 02/13] OMAP4 clock: drop the CLOCK_IN_OMAP4430 clock flag

To: linux-omap, linux-arm-kernel; +Cc: Rajendra Nayak, Benoît Cousson
The CLOCK_IN_OMAP4430 clock flag is not currently needed in the OMAP4
ES1 clock tree, and platform discrimination via clock flags is
deprecated in favor of the clkdev mechanism, so, drop it. (The OMAP4
clock tree autogeneration script has been updated accordingly.)

* [PATCH 02/13] OMAP4 clock: drop the CLOCK_IN_OMAP4430 clock flag
@ 2010-02-11 18:16 ` Paul Walmsley
0 siblings, 0 replies; 44+ messages in thread
From: Paul Walmsley @ 2010-02-11 18:16 UTC (permalink / raw)
To: linux-arm-kernel
The CLOCK_IN_OMAP4430 clock flag is not currently needed in the OMAP4
ES1 clock tree, and platform discrimination via clock flags is
deprecated in favor of the clkdev mechanism, so, drop it. (The OMAP4
clock tree autogeneration script has been updated accordingly.)

* [PATCH 03/13] OMAP2xxx clock: GFX functional clock rates are not independently changeable

According to the OMAP242x TRM Rev X Figure 5-15 "Clock Output Control
- Functional Clocks 2", the GFX functional clocks should be marked
both DELAYED_APP and CONFIG_PARTICIPANT, meaning that their rates must
be reprogrammed as part of a larger OPP set change.

clocks that are not rate-changeable or that use non-clksel rate changing code
(e.g., virt_prcm_set).

It turns out that the only purpose of the CONFIG_PARTICIPANT clock
flag is to prevent omap2_clk_set_rate() and omap2_clk_set_parent()
from being executed on clocks with that flag set. The rate-changing
component can be more directly accomplished by dropping the .set_rate
and .round_rate function pointers from those CONFIG_PARTICIPANT struct
clks. As far as the parent-changing component is concerned, it turns
out that none of the CONFIG_PARTICIPANT clocks have multiple parent
choices, so all that is necessary is for omap2_clk_set_parent() to
bail out early if the new parent is equal to the old parent.
Implement this change and get rid of the flag, which has always had a
confusing name (it appears to be a Kconfig option, falsely).

* [PATCH 05/13] OMAP2 clock: drop CONFIG_PARTICIPANT clock flag
@ 2010-02-11 18:17 ` Paul Walmsley
0 siblings, 0 replies; 44+ messages in thread
From: Paul Walmsley @ 2010-02-11 18:17 UTC (permalink / raw)
To: linux-arm-kernel
It turns out that the only purpose of the CONFIG_PARTICIPANT clock
flag is to prevent omap2_clk_set_rate() and omap2_clk_set_parent()
from being executed on clocks with that flag set. The rate-changing
component can be more directly accomplished by dropping the .set_rate
and .round_rate function pointers from those CONFIG_PARTICIPANT struct
clks. As far as the parent-changing component is concerned, it turns
out that none of the CONFIG_PARTICIPANT clocks have multiple parent
choices, so all that is necessary is for omap2_clk_set_parent() to
bail out early if the new parent is equal to the old parent.
Implement this change and get rid of the flag, which has always had a
confusing name (it appears to be a Kconfig option, falsely).

* [PATCH 06/13] OMAP clock: compress clock flags down to a u8

There are now only eight OMAP clock flags, so renumber the flags to
fit in a u8 and shrink the size of struct clk.flags from a u32 to a
u8. The intention is to save memory.

After the clkdev conversion, the struct clk.id became superfluous, so,
drop it. Bring the clock names closer to the TRMs and ensure they are
unique for debugfs.

* [PATCH 07/13] OMAP clock: drop .id field; ensure each clock has a unique name
@ 2010-02-11 18:17 ` Paul Walmsley

From: Paul Walmsley @ 2010-02-11 18:17 UTC (permalink / raw)
To: linux-arm-kernel
After the clkdev conversion, the struct clk.id became superfluous, so,
drop it. Bring the clock names closer to the TRMs and ensure they are
unique for debugfs.

* [PATCH 08/13] OMAP3/4 clock: split into per-chip family files

clock34xx_data.c now contains data for the OMAP34xx family, the
OMAP36xx family, and the OMAP3517 family, so rename it to
clock3xxx_data.c. Rename clock34xx.c to clock3xxx.c, and move the
chip family-specific clock functions to clock34xx.c, clock36xx.c, or
clock3517.c, as appropriate. So now "clock3xxx.*" refers to the OMAP3
superset.
The main goal here is to prepare to compile chip family-specific clock
functions only for kernel builds that target that chip family. To get to
that point, we also need to add CONFIG_ARCH_* options for those other
chip families; that will be done in a future patch, planned for 2.6.35.
OMAP4 is also affected by this. It duplicated the OMAP3 non-CORE DPLL
clkops structure. The OMAP4 variant of this clkops structure has been
removed, and since there was nothing else currently in clock44xx.c, it
too has been removed -- it can always be added back later when there
is some content for it. (The OMAP4 clock autogeneration scripts have been
updated accordingly.)

* [PATCH 08/13] OMAP3/4 clock: split into per-chip family files
@ 2010-02-11 18:17 ` Paul Walmsley
0 siblings, 0 replies; 44+ messages in thread
From: Paul Walmsley @ 2010-02-11 18:17 UTC (permalink / raw)
To: linux-arm-kernel
clock34xx_data.c now contains data for the OMAP34xx family, the
OMAP36xx family, and the OMAP3517 family, so rename it to
clock3xxx_data.c. Rename clock34xx.c to clock3xxx.c, and move the
chip family-specific clock functions to clock34xx.c, clock36xx.c, or
clock3517.c, as appropriate. So now "clock3xxx.*" refers to the OMAP3
superset.
The main goal here is to prepare to compile chip family-specific clock
functions only for kernel builds that target that chip family. To get to
that point, we also need to add CONFIG_ARCH_* options for those other
chip families; that will be done in a future patch, planned for 2.6.35.
OMAP4 is also affected by this. It duplicated the OMAP3 non-CORE DPLL
clkops structure. The OMAP4 variant of this clkops structure has been
removed, and since there was nothing else currently in clock44xx.c, it
too has been removed -- it can always be added back later when there
is some content for it. (The OMAP4 clock autogeneration scripts have been
updated accordingly.)

* [PATCH 09/13] OMAP2 clock: split OMAP2420, OMAP2430 clock data into their own files

From: Paul Walmsley @ 2010-02-11 18:17 UTC (permalink / raw)
To: linux-omap, linux-arm-kernel; +Cc: Tony Lindgren, Richard Woodruff
In preparation for multi-OMAP2 kernels, split
mach-omap2/clock2xxx_data.c into mach-omap2/clock2420_data.c and
mach-omap2/clock2430_data.c. 2430 uses a different device space
physical memory layout than past or future OMAPs, and we use a
different virtual memory layout as well, which causes trouble for
architecture-level code/data that tries to support both. We tried
using offsets from the virtual base last year, but those patches never
made it upstream; so after some discussion with Tony about the best
all-around approach, we'll just grit our teeth and duplicate the
data. The maintenance advantages of a single kernel config that
can compile and boot on OMAP2, 3, and 4 platforms are simply too
compelling.
This approach does have some nice benefits beyond multi-OMAP 2 kernel
support. The runtime size of OMAP2420-specific and OMAP2430-specific
kernels is smaller, since unused clocks for the other OMAP2 chip will
no longer be compiled in. (At some point we will mark the clock data
__initdata and allocate it during registration, which will eliminate
the runtime memory advantage.) It also makes the clock trees slightly
easier to read, since 2420-specific and 2430-specific clocks are no
longer mixed together.
This patch also splits 2430-specific clock code into its own file,
mach-omap2/clock2430.c, which is only compiled in for 2430 builds -
mostly for organizational clarity.
While here, fix a bug in the OMAP2430 clock tree: "emul_ck" was
incorrectly marked as being 2420-only, when actually it is present on
both OMAP2420 and OMAP2430.
Thanks to Tony for some good discussions about how to approach this
problem.

* [PATCH 09/13] OMAP2 clock: split OMAP2420, OMAP2430 clock data into their own files
@ 2010-02-11 18:17 ` Paul Walmsley

From: Paul Walmsley @ 2010-02-11 18:17 UTC (permalink / raw)
To: linux-arm-kernel
In preparation for multi-OMAP2 kernels, split
mach-omap2/clock2xxx_data.c into mach-omap2/clock2420_data.c and
mach-omap2/clock2430_data.c. 2430 uses a different device space
physical memory layout than past or future OMAPs, and we use a
different virtual memory layout as well, which causes trouble for
architecture-level code/data that tries to support both. We tried
using offsets from the virtual base last year, but those patches never
made it upstream; so after some discussion with Tony about the best
all-around approach, we'll just grit our teeth and duplicate the
data. The maintenance advantages of a single kernel config that
can compile and boot on OMAP2, 3, and 4 platforms are simply too
compelling.
This approach does have some nice benefits beyond multi-OMAP 2 kernel
support. The runtime size of OMAP2420-specific and OMAP2430-specific
kernels is smaller, since unused clocks for the other OMAP2 chip will
no longer be compiled in. (At some point we will mark the clock data
__initdata and allocate it during registration, which will eliminate
the runtime memory advantage.) It also makes the clock trees slightly
easier to read, since 2420-specific and 2430-specific clocks are no
longer mixed together.
This patch also splits 2430-specific clock code into its own file,
mach-omap2/clock2430.c, which is only compiled in for 2430 builds -
mostly for organizational clarity.
While here, fix a bug in the OMAP2430 clock tree: "emul_ck" was
incorrectly marked as being 2420-only, when actually it is present on
both OMAP2420 and OMAP2430.
Thanks to Tony for some good discussions about how to approach this
problem.

* [PATCH 10/13] OMAP2430 clock: make func_96m_ck parent-selectable

From: Paul Walmsley @ 2010-02-11 18:18 UTC (permalink / raw)
To: linux-omap, linux-arm-kernel
func_96m_ck was incorrectly marked as being rate-selectable, when in
fact it is only parent-selectable. Remove the .set_rate and .round_rate
function pointers for this clk.

* [PATCH 11/13] OMAP2 clock: drop DELAYED_APP clock flag
2010-02-11 18:16 ` Paul Walmsley
@ 2010-02-11 18:18 ` Paul Walmsley
-1 siblings, 0 replies; 44+ messages in thread
From: Paul Walmsley @ 2010-02-11 18:18 UTC (permalink / raw)
To: linux-omap, linux-arm-kernel; +Cc: Richard Woodruff
All of the clocks that are marked with DELAYED_APP are changed as part
of the virt_prcm_set OPP virtual clock. On 24xx, these clocks all
need to be changed as part of a group to keep the clock tree
functional - hence the need for the VALID_CONFIG bit, which is not
present on later OMAPs. These clocks should not be rate-changed
independently. So prevent these clocks from being changed
independently by dropping their .round_rate and .set_rate function
pointers. It then turns out that the DELAYED_APP clock flag is no
longer useful, so drop it and the associated code and renumber the
clock flags.

* [PATCH 11/13] OMAP2 clock: drop DELAYED_APP clock flag
@ 2010-02-11 18:18 ` Paul Walmsley

From: Paul Walmsley @ 2010-02-11 18:18 UTC (permalink / raw)
To: linux-arm-kernel
All of the clocks that are marked with DELAYED_APP are changed as part
of the virt_prcm_set OPP virtual clock. On 24xx, these clocks all
need to be changed as part of a group to keep the clock tree
functional - hence the need for the VALID_CONFIG bit, which is not
present on later OMAPs. These clocks should not be rate-changed
independently. So prevent these clocks from being changed
independently by dropping their .round_rate and .set_rate function
pointers. It then turns out that the DELAYED_APP clock flag is no
longer useful, so drop it and the associated code and renumber the
clock flags.

* [PATCH 12/13] OMAP clock: drop RATE_FIXED clock flag

To: linux-omap, linux-arm-kernel; +Cc: Richard Woodruff
The RATE_FIXED clock flag is pointless. In the OMAP1 clock code, it
simply causes the omap1_clk_round_rate() function to return the
current rate of the clock. omap1_clk_round_rate(), however, should
never be called for a fixed-rate clock, since none of these clocks
have a .round_rate function pointer set in their struct clk records.
Similarly, in the OMAP2+ clock code, the RATE_FIXED flag just causes
the clock code to emit a warning if the OMAP clock maintainer was
foolish enough to add a .round_rate function pointer to a fixed-rate
clock. "Doctor, it hurts when I pretend that a fixed-rate clock is
rate-changeable." "Then don't pretend that a fixed-rate clock is
rate-changeable." It has no functional value. This patch drops the
RATE_FIXED clock flag, removing it from all clocks that are so marked.

* [PATCH 12/13] OMAP clock: drop RATE_FIXED clock flag
@ 2010-02-11 18:18 ` Paul Walmsley

The RATE_FIXED clock flag is pointless. In the OMAP1 clock code, it
simply causes the omap1_clk_round_rate() function to return the
current rate of the clock. omap1_clk_round_rate(), however, should
never be called for a fixed-rate clock, since none of these clocks
have a .round_rate function pointer set in their struct clk records.
Similarly, in the OMAP2+ clock code, the RATE_FIXED flag just causes
the clock code to emit a warning if the OMAP clock maintainer was
foolish enough to add a .round_rate function pointer to a fixed-rate
clock. "Doctor, it hurts when I pretend that a fixed-rate clock is
rate-changeable." "Then don't pretend that a fixed-rate clock is
rate-changeable." It has no functional value. This patch drops the
RATE_FIXED clock flag, removing it from all clocks that are so marked.

* [PATCH v2 08/13] OMAP3/4 clock: split into per-chip family files

[-- Attachment #1: Type: TEXT/PLAIN, Size: 37273 bytes --]
clock34xx_data.c now contains data for the OMAP34xx family, the
OMAP36xx family, and the OMAP3517 family, so rename it to
clock3xxx_data.c. Rename clock34xx.c to clock3xxx.c, and move the
chip family-specific clock functions to clock34xx.c, clock36xx.c, or
clock3517.c, as appropriate. So now "clock3xxx.*" refers to the OMAP3
superset.
The main goal here is to prepare to compile chip family-specific clock
functions only for kernel builds that target that chip family. To get to
that point, we also need to add CONFIG_ARCH_* options for those other
chip families; that will be done in a future patch, planned for 2.6.35.
OMAP4 is also affected by this. It duplicated the OMAP3 non-CORE DPLL
clkops structure. The OMAP4 variant of this clkops structure has been
removed, and since there was nothing else currently in clock44xx.c, it
too has been removed -- it can always be added back later when there
is some content for it. (The OMAP4 clock autogeneration scripts have been
updated accordingly.)
This second version of the patch fixes some minor errors where the AM35xx
files were renamed, but the #includes weren't.

* [PATCH v2 08/13] OMAP3/4 clock: split into per-chip family files
@ 2010-02-16 0:58 ` Paul Walmsley
0 siblings, 0 replies; 44+ messages in thread
From: Paul Walmsley @ 2010-02-16 0:58 UTC (permalink / raw)
To: linux-arm-kernel
clock34xx_data.c now contains data for the OMAP34xx family, the
OMAP36xx family, and the OMAP3517 family, so rename it to
clock3xxx_data.c. Rename clock34xx.c to clock3xxx.c, and move the
chip family-specific clock functions to clock34xx.c, clock36xx.c, or
clock3517.c, as appropriate. So now "clock3xxx.*" refers to the OMAP3
superset.
The main goal here is to prepare to compile chip family-specific clock
functions only for kernel builds that target that chip family. To get to
that point, we also need to add CONFIG_ARCH_* options for those other
chip families; that will be done in a future patch, planned for 2.6.35.
OMAP4 is also affected by this. It duplicated the OMAP3 non-CORE DPLL
clkops structure. The OMAP4 variant of this clkops structure has been
removed, and since there was nothing else currently in clock44xx.c, it
too has been removed -- it can always be added back later when there
is some content for it. (The OMAP4 clock autogeneration scripts have been
updated accordingly.)
This second version of the patch fixes some minor errors where the AM35xx
files were renamed, but the #includes weren't.

* [PATCH v2 12/13] OMAP clock: drop RATE_FIXED clock flag
2010-02-11 18:18 ` Paul Walmsley
@ 2010-02-16 1:02 ` Paul Walmsley

From: Paul Walmsley @ 2010-02-16 1:02 UTC (permalink / raw)
To: linux-omap, linux-arm-kernel; +Cc: Richard Woodruff
The RATE_FIXED clock flag is pointless. In the OMAP1 clock code, it
simply causes the omap1_clk_round_rate() function to return the
current rate of the clock. omap1_clk_round_rate(), however, should
never be called for a fixed-rate clock, since none of these clocks
have a .round_rate function pointer set in their struct clk records.
Similarly, in the OMAP2+ clock code, the RATE_FIXED flag just causes
the clock code to emit a warning if the OMAP clock maintainer was
foolish enough to add a .round_rate function pointer to a fixed-rate
clock. "Doctor, it hurts when I pretend that a fixed-rate clock is
rate-changeable." "Then don't pretend that a fixed-rate clock is
rate-changeable." It has no functional value. This patch drops the
RATE_FIXED clock flag, removing it from all clocks that are so marked.
This second version of the patch also drops the flag from the OMAP3
clocks - an oversight in the first revision.

* [PATCH v2 12/13] OMAP clock: drop RATE_FIXED clock flag
@ 2010-02-16 1:02 ` Paul Walmsley
0 siblings, 0 replies; 44+ messages in thread
From: Paul Walmsley @ 2010-02-16 1:02 UTC (permalink / raw)
To: linux-arm-kernel
The RATE_FIXED clock flag is pointless. In the OMAP1 clock code, it
simply causes the omap1_clk_round_rate() function to return the
current rate of the clock. omap1_clk_round_rate(), however, should
never be called for a fixed-rate clock, since none of these clocks
have a .round_rate function pointer set in their struct clk records.
Similarly, in the OMAP2+ clock code, the RATE_FIXED flag just causes
the clock code to emit a warning if the OMAP clock maintainer was
foolish enough to add a .round_rate function pointer to a fixed-rate
clock. "Doctor, it hurts when I pretend that a fixed-rate clock is
rate-changeable." "Then don't pretend that a fixed-rate clock is
rate-changeable." It has no functional value. This patch drops the
RATE_FIXED clock flag, removing it from all clocks that are so marked.
This second version of the patch also drops the flag from the OMAP3
clocks - an oversight in the first revision.

Just to comment on the naming, we should call additional cpu options
CONFIG_CPU_OMAP3630 etc instead of CONFIG_ARCH_OMAP to avoid confusion.
I thought about renaming CONFIG_ARCH_OMAP2420 and CONFIG_ARCH_OMAP2430
into CONFIG_CPU_OMAP2420 and CONFIG_CPU_OMAP2430, but as it covers
a bunch of drivers too I've postponed that to 2.6.35.
Any new options should be added as CONFIG_CPU_OMAP3630 and should not
be selectable. Instead, they should get automatically enabled based
on the selected boards in arch/arm/mach-omap2/Kconfig.
Regards,
Tony

Just to comment on the naming, we should call additional cpu options
CONFIG_CPU_OMAP3630 etc instead of CONFIG_ARCH_OMAP to avoid confusion.
I thought about renaming CONFIG_ARCH_OMAP2420 and CONFIG_ARCH_OMAP2430
into CONFIG_CPU_OMAP2420 and CONFIG_CPU_OMAP2430, but as it covers
a bunch of drivers too I've postponed that to 2.6.35.
Any new options should be added as CONFIG_CPU_OMAP3630 and should not
be selectable. Instead, they should get automatically enabled based
on the selected boards in arch/arm/mach-omap2/Kconfig.
Regards,
Tony

Or CONFIG_SOC_OMAP3630. OMAP3630 is not a CPU type - it's a description
of the whole system. The CPU is just the processor and caches without
peripherals.
