[PATCH v2 0/3] ARM: EXYNOS: DT-enabled support for Universal C210

[PATCH v2 0/3] ARM: EXYNOS: DT-enabled support for Universal C210

[Tomasz Figa]

This series intends to add support for Universal C210 board using Device
Tree. Main difference from other boards based on Exynos 4210 is that
hardware revision of the SoC used on Universal C210 does not support MCT
timers and legacy PWM timers must be used instead.

First patch adds device tree node for PWM block available on Exynos4 SoCs,
second patch adds support for Exynos4210 rev0 SoC in exynos_init_time()
and third patch introduces initial device tree for Universal C210 board.

Depends on my series for PWM timers rework:

[PATCH v2 2/3] ARM: EXYNOS: Fix support of Exynos4210 rev0 SoC

[Tomasz Figa]

This patch extends exynos_init_time() function to handle Exynos4210 rev0
SoC, which differs in availability of system timers and needs different
clocksource initialization.

This makes it possible to use exynos_init_time() function as init_time
callback for all Exynos-based boards, including Universal_C210, which
originally had to use samsung_timer_init().

[PATCH v2 3/3] ARM: dts: exynos4210: Add basic dts file for universal_c210 board

[Tomasz Figa]

This patch adds basic device tree sources for Universal C210 board.

Currently support includes:
- eMMC
- serial
- max8952 and max8998 voltage regulators.
- gpio-keys

More support will be added in further patches.

[PATCH v2 3/3] ARM: dts: exynos4210: Add basic dts file for universal_c210 board

[Tomasz Figa]

This patch adds basic device tree sources for Universal C210 board.

Currently support includes:
- eMMC
- serial
- max8952 and max8998 voltage regulators.
- gpio-keys

More support will be added in further patches.

Since the samsung-time rework patches were replaced with a non-invasive subset 
with different semantics (going to send them in a while), this patch should be 
replaced with new version I'm going to send (in a while as well).

Oh, OK. You want to replace with new patches you will send. I dropped 
this series in my late dt branch.

BTW, the series should depend on your samsung-time patches, right?

One more note, this makes following build error.

arch/arm/mach-exynos/built-in.o: In function `exynos_init_time':
arch/arm/mach-exynos/common.c:424: undefined reference to 
`samsung_timer_init'
make: *** [vmlinux] Error 1

Thanks.
