2014-09-20drm/exynos: mipi-dsi: consider non-continuous clock modeInki Dae
This patch adds non-continuous clock mode support Clock mode on Clock Lane is continuous clock by default. So if we want to transmit data in non-continuous clock mode to reduce power consumption, then host driver should set DSIM_CLKLANE_STOP bit. In this case, host controller turns off HS clock between high speed transmissions. For this, this patch adds a new bit, DSIM_CLKLANE_STOP, and makes the host driver sets this bit only in case that dsi->mode_flags has MIPI_DSI_CLOCK_NON_CONTINUOUS flag.

2014-09-10drm: add driver->set_busid() callbackDavid Herrmann
One step closer to dropping all the drm_bus_* code: Add a driver->set_busid() callback and make all drivers use the generic helpers. Nouveau is the only driver that uses two different bus-types with the same drm_driver. This is totally broken if both buses are available on the same machine (unlikely, but lets be safe). Therefore, we create two different drivers for each platform during module_init() and set the set_busid() callback respectively.

2014-08-03drm/exynos: hdmi: enable exynos 4210 and 4x12 soc supportMarek Szyprowski
Configuration sets for Exynos 4210 and 4x12 SoC were already defined in Exynos HDMI and Mixed drivers, but they lacked proper linking to device tree 'compatible' values. This patch fixes this issue adding support for following compatible values: samsung,exynos4210-mixer, samsung,exynos4212-mixer and samsung,exynos4210-hdmi. It also corrects access to sclk_mixer clock, which is available only on Exynos 4210. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
