[PATCHv4 00/35] ARM: OMAP2+: PRCM / SCM cleanups against 4.0-rc1

[Tero Kristo]

Hi,

Changes in this set compared to v3:

- Changed the SCM module DT node layout based on comments from Tony;
  basically the wkup / core are split into their own nodes now. This
  applies for omap3, omap4, omap5 and dra7, rest of the SoCs have their
  control module integrated as one instance (Patch 26, 30, 33, 34)
- Changed the tisyscon node name to scm_conf. This name is more
  descriptive for the purpose being used, scm_conf was already used
  as an alias (Patch 24, 25, 27, 29)
- Rest of the patches have no changes compared to v3.

This avoids conflicts in the global namespace, and is more descriptive
of the purpose anyway.

[PATCHv4 03/35] ARM: OMAP2+: PRM: add generic API for clear_mod_irqs

[Tero Kristo]

OMAP2/3 now use generic API for the prm_clear_mod_irqs, the SoC specific
implementation details are provided through prm_ll_data.

[PATCHv4 05/35] ARM: OMAP4+: PRM: move omap_prm_base_init under OMAP4 PRM driver

[Tero Kristo]

There is no need to call this separately from io.c, rather this can be
done commonly under the PRM driver.

[PATCHv4 07/35] ARM: OMAP4: PRM: move omap4xxx_prm_init earlier in init order

[Tero Kristo]

OMAP4 has different ordering of PRM and CM init calls in the early init.
Re-oder these accordingly for OMAP4 also. This is needed so that we
can do some optimizations in the following patches for the PRCM init.

[PATCHv4 08/35] clk: ti: fix ti_clk_get_reg_addr error handling

[Tero Kristo]

There is a case where NULL can be a valid return value for
ti_clk_get_reg_addr, specifically the case where both the provider index
and register offsets are zero. In this case, the current error checking
against a NULL pointer will fail. Thus, change the API to return a
ERR_PTR value in an error case, and change all the users of this API to
check against IS_ERR instead.

[PATCHv4 08/35] clk: ti: fix ti_clk_get_reg_addr error handling

[Tero Kristo]

There is a case where NULL can be a valid return value for
ti_clk_get_reg_addr, specifically the case where both the provider index
and register offsets are zero. In this case, the current error checking
against a NULL pointer will fail. Thus, change the API to return a
ERR_PTR value in an error case, and change all the users of this API to
check against IS_ERR instead.

[PATCHv4 09/35] Documentation: DT: document PRCM compatible strings for dm81x SoCs

[Tero Kristo]

These PRCM nodes were earlier added in patch 7800064ba5 ("ARM: dts: Add
basic dm816x device tree configuration"), but the documentation for
the same wasn't added. Fix this by adding the missing compatible strings
under the generic prcm.txt document.

[PATCHv4 11/35] ARM: OMAP2+: clock: move clock provider infrastructure to clock driver

[Tero Kristo]

Splits the clock provider init out of the PRM driver and moves it to
clock driver. This is needed so that once the PRCM drivers are separated,
they can logically just access the clock driver not needing to go through
common PRM code. This would be wrong in the case of control module for
example.

[PATCHv4 13/35] ARM: OMAP2+: CM: determine CM base address from device tree

[Tero Kristo]

There is no need to provide the CM base address through a low-level API
from the low-level IO init, as this information is available through DT.
Re-routed the parsing function to be called from the CM drivers also to
simplify the implementation under io.c.

[PATCHv4 13/35] ARM: OMAP2+: CM: determine CM base address from device tree

[Tero Kristo]

There is no need to provide the CM base address through a low-level API
from the low-level IO init, as this information is available through DT.
Re-routed the parsing function to be called from the CM drivers also to
simplify the implementation under io.c.

[PATCHv4 14/35] ARM: OMAP2+: PRM: determine PRM base address from device tree

[Tero Kristo]

There is no need to provide the PRM base address through a low-level API
from the low-level IO init, as this information is available through DT.
Re-routed the parsing function to be called from the PRM drivers also to
simplify the implementation under io.c.

[PATCHv4 14/35] ARM: OMAP2+: PRM: determine PRM base address from device tree

[Tero Kristo]

There is no need to provide the PRM base address through a low-level API
from the low-level IO init, as this information is available through DT.
Re-routed the parsing function to be called from the PRM drivers also to
simplify the implementation under io.c.

[PATCHv4 15/35] ARM: OMAP2+: control: determine control module base address from DT

[Tero Kristo]

There is no need to provide the control module base address through a
low-level API from the low-level IO init, as this information is
available through DT. This patch adds a new API to initialize the
control module though, but mostly makes the old API obsolete. The
old API can be completely removed once OMAP3 is made DT only.

[PATCHv4 15/35] ARM: OMAP2+: control: determine control module base address from DT

[Tero Kristo]

There is no need to provide the control module base address through a
low-level API from the low-level IO init, as this information is
available through DT. This patch adds a new API to initialize the
control module though, but mostly makes the old API obsolete. The
old API can be completely removed once OMAP3 is made DT only.

[PATCHv4 16/35] ARM: OMAP2+: PRM: move SoC specific init calls within a generic API

[Tero Kristo]

This gets rid of need for some exported driver APIs, and simplifies the
initialization of the PRM driver. Done in preparation to make PRM a
separate driver. The init data is now also passed to the SoC specific
implementations, allowing future expansion to add feature flags etc.

[PATCHv4 16/35] ARM: OMAP2+: PRM: move SoC specific init calls within a generic API

[Tero Kristo]

This gets rid of need for some exported driver APIs, and simplifies the
initialization of the PRM driver. Done in preparation to make PRM a
separate driver. The init data is now also passed to the SoC specific
implementations, allowing future expansion to add feature flags etc.

[PATCHv4 17/35] ARM: OMAP4+: PRM: determine prm_device_inst based on DT compatibility

[Tero Kristo]

PRM device instance offset is now provided through the prm_init_data.
This gets rid of some cpu_is_X / soc_is_X calls from PRM core code,
preparing for PRM to be its own separate driver.

[PATCHv4 18/35] ARM: OMAP2+: CM: move SoC specific init calls within a generic API

[Tero Kristo]

This gets rid of need for some exported driver APIs, and simplifies the
initialization of the CM driver. Done in preparation to make CM a
separate driver. The init data is now also passed to the SoC specific
implementations, allowing future expansion to add feature flags etc.

[PATCHv4 19/35] ARM: OMAP4+: PRM: setup prm_features from the PRM init time flags

[Tero Kristo]

Currently some cpu_is_X checks are used to setup prm_features, however
the same can be accomplished by just passing these flags from the PRM
init data. This is done in preparation to make PRM a separate driver.

[PATCHv4 20/35] ARM: OMAP4+: PRM: get rid of cpu_is_omap44xx calls from interrupt init

[Tero Kristo]

The compatible DT node is now passed with the prm init, so there is no
need to do node matching here again. Added a new flag to the init data
also, to detect default IRQ support for OMAP4. Also, any booting omap4
DT setup always has a PRM node, so there is no need to check against
the special case where it would be missing.

[PATCHv4 21/35] ARM: OMAP2+: clock: add low-level support for regmap

[Tero Kristo]

Some of the TI clock providers will be converted to use syscon, thus
low-level regmap support is needed for the clock drivers also. This
patch adds this support, which can be enabled for individual drivers
in later patches.

[PATCHv4 24/35] ARM: OMAP2+: control: add syscon support for register accesses

[Tero Kristo]

Control module driver needs to support syscon for register accesses, as
the DT hierarchy for control module driver is going to be changed. All
the control module related features will be moved under control module
node, including clocks, pinctrl, and generic configuration register
access. Temporary iomap is still provided very early in the boot for
access while syscon is not yet ready.

[PATCHv4 24/35] ARM: OMAP2+: control: add syscon support for register accesses

[Tero Kristo]

Control module driver needs to support syscon for register accesses, as
the DT hierarchy for control module driver is going to be changed. All
the control module related features will be moved under control module
node, including clocks, pinctrl, and generic configuration register
access. Temporary iomap is still provided very early in the boot for
access while syscon is not yet ready.

[PATCHv4 28/35] ARM: dts: am43xx-epos-evm: fix pinmux node layout

[Tero Kristo]

Pinmux node should be a reference to the base one, not a complete re-write
of it. Having the node like this also prevents modifying the node layout
in the base am4372.dtsi file, which is needed for control module changes.

[PATCHv4 31/35] ARM: OMAP4: display: convert display to use syscon for dsi muxing

[Tero Kristo]

The legacy control module APIs will be gone, thus convert the display
driver to use syscon. This change should eventually be moved to
display driver from the board directory.

[PATCHv4 35/35] ARM: OMAP4+: control: add support for initializing control module via DT

[Tero Kristo]

OMAP4, OMAP5 and DRA7 now parse DT entries for control module address spaces,
and set up syscon mappings appropriately. Low level IO init is updated to
remove the legacy control module mappings for these devices also.

Oops I still have a bit of an issue with this, sorry I should have
been more clear last time.

Now it's hard to figure out which children belong to l4_cfg and which
ones to l4_wkup. I suggest we set them up as completely separate blocks
as that's what they are.

Below is an example of what I think things should look like for omap4,
maybe take a look at that and see if that makes sense for you?

It may need to be patched in separate parts to keep the patches readable
though :)

Tony

Boots for me also for 2430-sdp.

But for dm8168-evm, it fails early on, see below.

The example I posted has some l4_cfg vs SCM confusion as pointed out by
Tero while we chatted about it. Also l4_wkup is a child of l4_cfg on
omap4, while on omap5 they are separate.

Below are some examples of what we came up with that now follows omap4460
TRM "Figure 2-1. Interconnect Overview" and "Table 2-3. L4_CFG Memory
Space Mapping". Also an example for omap3 is included.

Tero, maybe just do the minimal changes for now as we don't need to move
all of it at once?

Regards,

Tony

The example I posted has some l4_cfg vs SCM confusion as pointed out by
Tero while we chatted about it. Also l4_wkup is a child of l4_cfg on
omap4, while on omap5 they are separate.

Below are some examples of what we came up with that now follows omap4460
TRM "Figure 2-1. Interconnect Overview" and "Table 2-3. L4_CFG Memory
Space Mapping". Also an example for omap3 is included.

Tero, maybe just do the minimal changes for now as we don't need to move
all of it at once?

Regards,

Tony
