This patchset is based on exynos-drm-next-todo branch of Inki Dae's tree at: git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos.git I have just put up Rob's and Sean's idea of chaining up the bridges in code, and have implemented basic panel controls as a chained bridge. This works

2014-05-05 Thread Ajay Kumar
As of now, we can have only one bridge hanging off the encoder. With this patch, we allow multiple bridges to hang onto the same encoder with the use of a simple next_bridge ptr. The drm core calls bridge-funcs for the first bridge which is attached to it, and its upto the individual bridge

2014-05-05 Thread Tobias Jakobi
Hello Tomasz, thanks a lot for the support! The meaning of hdmiphy is ambiguous. In exynos4 spec there are _TWO_ components named HDMIPHY. The first one is a PLL that generates a clock for HDMI subsystem. This PLL is controlled by I2C. You can find an example of its bindings at:
