[PATCH v2 1/7] drm/exynos: move hdmiphy code to hdmiphy i2c driver
Rahul Sharma
rahul.sharma at samsung.com
Tue Oct 22 12:11:02 CEST 2013
Exynos hdmiphy operations and configs are kept inside
the hdmi driver. Hdmiphy related code is very tightly
coupled with hdmi IP driver.
This patch moves hdmiphy related code to hdmiphy I2C driver
which supports hdmiphys which are accessible through i2c
control bus for example in exynos4210, exynos4212 and
exynos5250.
