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 Exynos 4 SoCs,
second patch adds support for Exynos4210 EVT0 SoC to mach-exynos4-dt and
third patch introduces initial device tree for Universal C210 board.
Depends on my series for PWM timers rework:
[PATCH v4 00/14] ARM: samsung-time: Prepare for multiplatform support
(http://thread.gmane.org/gmane.linux.kernel.samsung-soc/17464)
Tested on Universal C210 board.

This patch extends mach-exynos4-dt generic board file with support for
Exynos4210 EVT0 SoC, which differs in availability of system timers and
needs different time initialization.

This patch adds basic device tree sources for Universal C210 board.
Currently support includes:
- eMMC
- serial
- max8952 and max8998 voltage regulators.
- gpio-keys
- touchscreen
More support will be added in further patches.

From: Tomasz Figa @ 2013-04-04 16:51 UTC (permalink / raw)
To: linux-arm-kernel
This patch adds basic device tree sources for Universal C210 board.
Currently support includes:
- eMMC
- serial
- max8952 and max8998 voltage regulators.
- gpio-keys
- touchscreen
More support will be added in further patches.
