[PATCH v2 0/5] Fix Arndale Octa/Peach Pi boot on Audio subsystem clocks

[Krzysztof Kozlowski]

Hi,

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 platform.

This solves boot failure of Peach Pi/Pit and Arndale Octa [1].

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.

Best regards,
Krzysztof Kozlowski
