Subject: [PATCH v3 00/13] ARM: EXYNOS: Fix Universal C210 support
Date: Tue, 23 Apr 2013 17:46:21 +0200 [thread overview]
Message-ID: <1366731994-7478-1-git-send-email-t.figa@samsung.com> (raw)
This series intends to fix support for Universal C210 board in mainline.
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 (and the biggest) part of the series deals with cleaning up and
fixing the samsung_pwm_timer clocksource driver, that was posted
recently by Arnd. In addition the driver is prepared to share the
hardware with PWM driver that will be reworked later, since it is not
a component crucial for system operation.
Second part fixes ATAGS support of Exynos 4210 rev0 SoC, which needs
different timer initialization, using the new samsung_pwm_timer driver.
Third and last part adds Device Tree-based support for Universal C210
board by providing device tree sources for it.
On Universal C210 board, both with and without DT:
