[PATCH 0/4] Control clock for accessing syscon provided arasan IP

From: Shawn Lin
Date: Mon Aug 29 2016 - 04:08:24 EST

This patchset is gonna take over the ownership of aclk_emmc_grf
by sdhci-of-arasan which is used to access corecfg_* stuff provided
by arasan. This clock is optional for sdhci-of-arasan which means we
would not break the driver without adding this. But we strongly
recommend the upcoming users whose platforms have the similar
cases to add this rather than to add any flags for their specific
clock drivers to make this clock always on.

This patchset is based on linux-next. And patch 4 should *not* be
landed before others, so it would be nice to pack these four patches
via Ulf's tree tree Heiko's ack for rockchip part, or vice versa. :)
