This patch series enables support for pin controller driver for Exynos4210 SoC
based device tree enabled platforms. The first patch in this series adds the
pin group nodes for each of the three pin controller instances, but it is not
a exhaustive list of all possible pin group nodes. As the coverage of pinctrl
driver is extended device drivers used on Exynos4210 platforms, additional
pin group nodes can be added as required.

* [PATCH 1/2] ARM: dts: Add pinctrl node entries for Samsung Exynos4210 SoC

Samsung pinctrl driver was written to be usable on all of the Samsung
application processors starting from 24xx series to the latest
Exynos5.
The gpio/pinmux/pinconfig controllers on these SoC have varying
capabilities. Some of the banks in s3c24xx series support mux function
but do not support pull up/down (pud) or driver strength (drv).
s3c64xx soc's have banks that support pin mux and 'pud' but do not
support 'drv'. And there are banks that do not support mux function
but support 'pud' and 'drv'. Further, a given SoC can have multiple
combinations of different bank types.
In addition to this, there are two more properties for mux and pud
values in power down mode in some of the samsung SoC's.
To keep the bindings common across all the possible Samsung SoC's, the
mux, pud and drv properties were split so that the parsing code in the
Samsung pinctrl driver remains generic for all the possible
combinations of pin banks and SoC's.
Thanks,
Thomas.

Samsung pinctrl driver was written to be usable on all of the Samsung
application processors starting from 24xx series to the latest
Exynos5.
The gpio/pinmux/pinconfig controllers on these SoC have varying
capabilities. Some of the banks in s3c24xx series support mux function
but do not support pull up/down (pud) or driver strength (drv).
s3c64xx soc's have banks that support pin mux and 'pud' but do not
support 'drv'. And there are banks that do not support mux function
but support 'pud' and 'drv'. Further, a given SoC can have multiple
combinations of different bank types.
In addition to this, there are two more properties for mux and pud
values in power down mode in some of the samsung SoC's.
To keep the bindings common across all the possible Samsung SoC's, the
mux, pud and drv properties were split so that the parsing code in the
Samsung pinctrl driver remains generic for all the possible
combinations of pin banks and SoC's.
Thanks,
Thomas.

I don't think this works, since PINCTRL_SAMSUNG is not default "y"
(nor should it be).
For the platforms I converted I had to select both the subsystem and
the indivudual driver, as is already done for some GPIO controllers
for example:
select PINCTRL
select PINCTRL_SAMSUNG

Apart from the pin-pud and pin-drv stuff this patch looks fine. These two
things I want to discuss in the other mail thread (controller core) first.

I think I got this wrong. PINCTRL_SAMSUNG depends of OF, which is not
correct. The correct way would be select PINCTRL_SAMSUNG from
PINCTRL_EXYNOS4. I will fix this.
