This patch set adds support for the common clock framwork to the remaining atml
SoCs: at91rm9200, at91sam9260, at91sam9263, at91sam9g45.
It also defines the necessary main crystal and slow crystal frequencies.
I couldn't find datasheets for the following boards:
- mpa1600
- ge863-pro3
- animeo_ip
- tny_a9260
For those, I assumed the 32kHz crystal is present on the board as this is the
most common implementation (only one board doesn't have it). Please correct me
if this is wrong.
I could not test at91rm9200 as I don't own any board with that chip.

When the main crystal frequency is not set, the main clock is approximated using
the MAINF value in the CKGR_MCFR register. Warn the user in that case.

* [PATCH 06/33] ARM: at91: move at91rm9200 SoC to the CCF

This patch removes the selection of AT91_USE_OLD_CLK when selecting at91rm9200
SoC support. This will automatically enable COMMON_CLK_AT91 option and add
support for at91 common clk implementation.

This patch removes the selection of AT91_USE_OLD_CLK when selecting at91sam9260
SoCs support. This will automatically enable COMMON_CLK_AT91 option and add
support for at91 common clk implementation.

* [PATCH 24/33] ARM: at91: move at91sam9g45 SoC to the CCF

This patch removes the selection of AT91_USE_OLD_CLK when selecting at91sam9g45
SoC support. This will automatically enable COMMON_CLK_AT91 option and add
support for at91 common clock implementation.

* [PATCH 30/33] ARM: at91: move at91sam9263 SoC to the CCF

This patch removes the selection of AT91_USE_OLD_CLK when selecting
at91sam9263 SoC support. This will automatically enable COMMON_CLK_AT91
option and add support for at91 common clock implementation.

Looks good overall, but I think this Kconfig snippet should be cleaned
up a little now:
config AT91_USE_OLD_CLK
bool
config AT91_PMC_UNIT
bool
default !ARCH_AT91X40
config COMMON_CLK_AT91
bool
default AT91_PMC_UNIT && USE_OF && !AT91_USE_OLD_CLK
select COMMON_CLK
config OLD_CLK_AT91
bool
default AT91_PMC_UNIT && AT91_USE_OLD_CLK
If I read this right, disabling 'USE_OF' results in still using
the old clock interface. Is that intentional? If you want to always
use COMMON_CLK now, the above can probably be simplified to
config AT91_PMC_UNIT
def_bool !ARCH_AT91X40
select COMMON_CLK
and all references to AT91_USE_OLD_CLK, COMMON_CLK_AT91 and
OLD_CLK_AT91 be removed.

Yeah, this is intentional we still have 30 or so boards that we have to
migrate to DT. Until then, we want to be able to boot a kernel without
CCF. The next step in the migration is to switch those boards to DT,
possibly using an hybrid DT/pdata approach until we can get rid of the
board files. Then, we will be able to get rid of the old clk
implementation (and a few other drivers still living in mach-at91).

possibly using an hybrid DT/pdata approach until we can get rid of the
board files. Then, we will be able to get rid of the old clk
implementation (and a few other drivers still living in mach-at91).

Ok, I see. Do you expect those 30 boards to work if COMMON_CLK_AT91
is enabled, or are there known problems with that?
If you have reason to believe it doesn't work, maybe you can expose
the selection of the clock interface to users, e.g. like
config COMMON_CLK_AT91
bool "Use common clock infrastructure"
depends on AT91_PMC_UNIT
default USE_OF
select COMMON_CLK
help
The at91 platform is migrating to use the common clk infrastructure
for all boards, but this has not been tested on some of the older
machines that do not use DT yet.
If you encounter problems on legacy boards, try disabling this option
and report the problem to linux-arm-kernel@lists.infradead.org.

We actually do the opposite, when a board without DT support is
selected, the old clock support is also selected even when also
selecting CONFIG_OF.

Ok, got it now. Yes, that makes sense.
I guess we can start doing the actual multiplatform enablement now,
which would be only for the DT-enabled boards -- all of Kconfig.non_dt
still has to depend on !ARCH_MULTIPLATFORM but we can make at91
either be built standalone (with board files) or multiplatform and
still support all SAM9 and RM9200 SoCs but without board files.

Just a nitpick, but the names defined in at91rm9200.c and in the
datasheet are tcX_clk and not tcbX_clk.
