[PATCH v3 0/7] Pad retentions support for Exynos5433

From: Marek Szyprowski
Date: Mon Jan 30 2017 - 08:07:58 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 #2 has compile dependency on #1.
Patch #3 has runtime dependency on commit fa59aa70907b2 ("soc: samsung:
pmu: Add dummy support for Exynos5433 SoC",
for-v4.11/drivers-soc-exynos-pmu-the-joy-never-ends branch).
Patch #4 has runtime dependency on #3.
Patch #5 has runtime dependency on commit 7547162ac3514 ("arm64: dts:
exynos: Add clocks to Exynos5433 LPASS module, next/dt64 branch).

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 30th January 2017
with the above mentioned patchset applied.

This is a part of a larger task, which goal is to add support for power
domains on Exynos5433 SoCs / TM2 boards. First version of the all patches
needed to get it working have been pushed to the following git repo:

- moved adding new PMU register defines to separate patch (requested by
Krzysztof Kozlowski)
- rebased onto Linux next-20170130 (removed "soc: samsung: pmu: Add dummy
support for Exynos5433 SoC" and "arm64: dts: exynos: Add clocks to
Exynos5433 LPASS module" patches, which are already merged)

- 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

v1: https://lkml.org/lkml/2017/1/25/214
- initial version
