rockchip: video: Lower hpd wait time

2016-07-05T16:38:56Z

Waiting 30 seconds for the hpd to go high seems a bit much, especially on headless boots. Lowering the timeout to 300ms. Sending as RFC because frankly i don't know what a sensible timeout is here, but 30 seconds is clearly not it :) Signed-off-by: Sjoerd Simons Reviewed-by: Simon Glass Dropped RFC tag: Signed-off-by: Simon Glass

clk: convert API to match reset/mailbox style

2016-06-19T23:05:55Z

The following changes are made to the clock API: * The concept of "clocks" and "peripheral clocks" are unified; each clock provider now implements a single set of clocks. This provides a simpler conceptual interface to clients, and better aligns with device tree clock bindings. * Clocks are now identified with a single "struct clk", rather than requiring clients to store the clock provider device and clock identity values separately. For simple clock consumers, this isolates clients from internal details of the clock API. * clk.h is split so it only contains the client/consumer API, whereas clk-uclass.h contains the provider API. This aligns with the recently added reset and mailbox APIs. * clk_ops .of_xlate(), .request(), and .free() are added so providers can customize these operations if needed. This also aligns with the recently added reset and mailbox APIs. * clk_disable() is added. * All users of the current clock APIs are updated. * Sandbox clock tests are updated to exercise clock lookup via DT, and clock enable/disable. * rkclk_get_clk() is removed and replaced with standard APIs. Buildman shows no clock-related errors for any board for which buildman can download a toolchain. test/py passes for sandbox (which invokes the dm clk test amongst others).

rockchip: video: Add LVDS support in vop driver

2016-03-14T21:24:10Z

LVDS have a different display out mode, add code to get right flag. The vop_ip decide display device and the remote_vop_id decide which vop was being used. So we should use the remote_vop_id to set DCLK_VOP. Signed-off-by: Jacob Chen Acked-by: Simon Glass

rockchip: video: Add a display driver for rockchip LVDS

2016-03-14T21:06:33Z

Some Rockchip SoCs support LVDS output. Add a display driver for this so that these displays can be used on supported boards. Signed-off-by: Jacob Chen Acked-by: Simon Glass

rockchip: video: Add a video-output driver

2016-01-22T03:42:36Z

Some rockchip SoCs include video output (VOP). Add a driver to support this. It can output via a display driver (UCLASS_DISPLAY) and currently HDMI and eDP are supported. Signed-off-by: Simon Glass

rockchip: video: Add a display driver for rockchip eDP

2016-01-22T03:42:36Z

Some Rockchip SoCs support embedded DisplayPort output. Add a display driver for this so that these displays can be used on supported boards. Signed-off-by: Simon Glass

rockchip: video: Add a display driver for rockchip HDMI

2016-01-22T03:42:36Z

Some Rockchip SoCs support HDMI output. Add a display driver for this so that these displays can be used on supported boards. Unfortunately this driver is not fully functional. It cannot reliably read EDID information over HDMI. This seems to be due to the clocks being incorrect - the I2C bus speed appears to be up to 100x slower than the clock settings indicate. The root cause may be in the clock logic. Signed-off-by: Simon Glass
