[PATCH 0/3] clk: samsung: auto clock gating fixes for PM

[André Draszik]

Hi,

The attached patches fix issues when CMUs have PM enabled and also a
needless warning message on older Exynos platforms relating to
automatic clock gating as reported by Marek.

Without these it's impossible to enable PM for a CMU when automatic
clock gating is also enabled. While currently no platform uses both,
patches to enable PM on gs101 are in the works but things stopped
working after the auto clock gating changes. I've verified that with
the patches here PM and runtime PM work again.

I've opted to add Fixes: tags to the PM-related patches even though no
current platform uses both, auto clock gating and PM, to ensure the
code is correct nevertheless. Please let me know if that's not desired.

Cheers,
Andre'
