Hi,
Changes since v3
================
1. Patch 1/3: Fix issues pointed by Sylwester.
2. Add Javier's tested-by [1]
Changes since v2
================
1. Patch 1 applied ("clk: samsung: Fix double add of syscore ops after
driver rebind"), remove it.
2. Squash patch 5 with "clk: samsung: Fix clock disable
failure because domain being gated". Suggested by Sylwester.
3. Patch 1/3: Fix issues pointed by Sylwester.
4. Patch 2/3: Fix redundant clk_disable when removing driver (clk is
already disabled). Add missing check !=null when removing driver.
5. Patch 3/3: Extend commit message.
Tomasz Figa had some questions about power domains on Exynos5420 in
relation to this patchset, but I haven't addressed all of them yet.
Changes since v1
================
1. clocks-audss: Reimplement own clock register functions instead
changing clk API. Minor fixes. (after idea from Tomasz Figa)
2. Add new patches: fix for pinctrl and minor fixes in clk-audss.
Description
===========
This patchset tries to solve dependency between AudioSS components
(clocks and GPIO) and main clock controller on Exynos 5420 platform.
This solves boot failure of Peach Pi/Pit and Arndale Octa [2].
Any access to memory of audss block (like checking if clock is enabled
or configuring GPIO) will hang if main audss clock is gated.
Tested on Arndale Octa board.
