[GIT PULL] ARM: EXYNOS: Improvements for 4.2, second try

[GIT PULL] ARM: EXYNOS: Improvements for 4.2, second try

[Krzysztof Kozlowski]

Dear Kukjin,

Updated pull request, replacing also the usage of soc_is_exynos4()
with of_machine_is_compatible(). You requested this in comments
for "ARM: EXYNOS: Fix failed second suspend on Exynos4".

This adds coupled cpuidle for Exynos3250 and improves the Exynos
code in few places. Everything for upcoming 4.2 merge window.
Description along with a tag.

Best regards,
Krzysztof

  ARM: plat-samsung: Constify platform_device_id (2015-05-11 11:05:31 +0900)

----------------------------------------------------------------
Extending cpuidle driver and improvements for Exynos based boards:
1. Replace soc_is_exynos4() with of_machine_is_compatible().
2. Add missing return-value checks and of_node_put() for power domain
   driver.
3. Fix missing clk_prepare in S3C24XX ADC driver.
4. Rework clock handling when switching power domains on/off. Instead
   of settting fixed parent in DTS we grab the parent clock before
   turning the domain off.
5. Add coupled cpuidle support for Exynos3250 to an existing
   cpuidle-exynos driver. As a result it enables AFTR mode
   (ARM-Off Top-Running) to be used by default on Exynos3250
   without the need to hot unplug CPU1 first.
6. Constify irq_domain_ops and platform_device_id.

Dear Kukjin,

Just humbly reminding - this stuff still waits for you :).

Sure, why not. I'll update it soon ;-)
