Subject: [PATCH] clk: exynos4: fix g2d/mdma clocks of exynos4x12
Date: Mon, 22 Jul 2013 17:12:30 +0900	[thread overview]
Message-ID: <1374480750-30962-1-git-send-email-chanho61.park@samsung.com> (raw)

The exynos4x12 has different address of GATE_IP_IMAGE reg. We should use
EXYNOS4X12_GATE_IP_IMAGE for g2d gating clocks instead of 4210's reg.
In case of mdma node, We don't use it for any exynos4 chipsets. I think we'll
need to change it to 'none' or leave it on.
