From: Marek Szyprowski
Date: Thu Jan 26 2017 - 03:36:03 EST
This patchset is a first step to add support for all power domains on
Exynos5433 SoCs. This patchset contains patches for Exynos pin control
driver and Exynos LPASS MFD driver, which are needed to make the
platform ready for adding power domains support.
Patches in this patchset depends on each other. They are order in such a
way to make the changes bisectable.
Patch #3 has runtime dependency on #1.
Patch #5 has runtime dependency on #3.
Patch #6 has runtime dependency on #4.
This patchset also directly depends on the "Move pad retention control to
Exynos pin controller driver" patchset:
Patches have been generated on top of linux-next from 25th January 2017.
This is a part of a larger task, which goal is to add support for power
domains on Exynos5433 SoCs / TM2 boards. All patches needed to get it
working have been pushed to the following git repo:
Samsung R&D Institute Poland
- fixed issues pointed by Krzysztof Kozlowski:
1. added more checks to Exynos PMU driver for NULL drvdata
2. reused EXYNOS_WAKEUP_FROM_LOWPWR in retention data for Exynos5433
3. converted lpass driver to devm_clk_get
4. added missing ->remove callback to lpass driver
- initial version
