Subject: [PATCH 1/7] clk: samsung: exynos4: set parent of sclk_hdmiphy to hdmi
Date: Tue, 18 Nov 2014 14:41:29 +0100	[thread overview]
Message-ID: <1416318089-24013-1-git-send-email-a.hajda@samsung.com> (raw)
In-Reply-To: <1415895785-26892-2-git-send-email-a.hajda@samsung.com>

sclk_hdmiphy clock is generated by HDMI-PHY and depends on hdmi gate clock.
The patch models this dependency using parent/child hirerarchy.

The patch fixes issue with system hangs during mixer device access, mixer uses
sclk_hdmiphy descendant clock.

Hi Tomasz,

This patch replaces the previous one [1], as it slightly better models
the clock tree/jungle.
