rockchip: video: Avoid using u8 in the HDMI driver

2016-11-26T00:59:32Z

It makes not sense using u8 to hold a value on a 32-bit or 64-bit machine. It can only bloat the code by forcing the compiler to mask the value. Change it to uint. Signed-off-by: Simon Glass

rockchip: video: Check for device in use

2016-11-26T00:59:31Z

Check whether a display device is in use before using it. Add a comment as to why two displays cannot currently be used at the same time. This allows us to remove the device-tree change that disables vopb on jerry. Signed-off-by: Simon Glass

rockchip: video: Correct VOP clock selection

2016-11-26T00:59:30Z

This code incorrectly uses the oscillator. It should use the clock selected in the device tree. Signed-off-by: Simon Glass Fixes: 135aa95 (clk: convert API to match reset/mailbox style)

rockchip: video: Correct HDMI data source selection

2016-11-26T00:59:30Z

This code currently always selects the second source. It only worked because both sources are set up. With the change to only init video devices that are present in the stdout environment variable, this fails. Fix it. Signed-off-by: Simon Glass

rockchip: Use rockchip_get_clk() to obtain the SoC clock

2016-07-26T02:46:45Z

The current code picks the first available clock. In U-Boot proper this is the oscillator device, not the SoC clock device. As a result the HDMI display does not work. Fix this by calling rockchip_get_clk() instead. Fixes: 135aa950 (clk: convert API to match reset/mailbox style) Signed-off-by: Simon Glass Acked-by: Anatolij Gustschin

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: Flush the cache when the display is updated

2016-05-27T16:23:08Z

Enable this option to correct display artifacts when a write-back cache is in use. Signed-off-by: Simon Glass

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
