drm/bridge: Add RGB to VGA bridge support

2016-10-10T05:28:44Z

Some boards have an entirely passive RGB to VGA bridge, based on DACs implemented by resistor ladders. Those might or might not have an i2c bus routed to the VGA connector in order to access the screen EDIDs. Add a bridge that doesn't do anything but expose the modes available on the screen, either based on the EDIDs if available, or based on the XGA standards.

drm: bridge: analogix/dp: mark symbols static where possible

We get 2 warnings when building kernel with W=1: drivers/gpu/drm/bridge/analogix/analogix_dp_core.c:1053:5: warning: no previous prototype for 'analogix_dp_get_modes' [-Wmissing-prototypes] drivers/gpu/drm/bridge/analogix/analogix_dp_core.c:1097:1: warning: no previous prototype for 'analogix_dp_detect' [-Wmissing-prototypes] In fact, both functions are only used in the file in which they are declared and don't need a declaration, but can be made static. So this patch marks both functions with 'static'.

drm/bridge: analogix_dp: Improve panel on time

2016-09-24T06:26:35Z

In order to reduce the time required to turn on the panel, this patch makes 2 assumptions: 1- In detect(): if there's a panel, we're connected. 2- In get_modes(): if there's a panel, let the panel driver decide if it should prepare/unprepare in order to get the modes. The first is straightforward, and shouldn't need further explanation. The second should eliminate the prepare/unprepare delays from get_modes() in most cases, since panels generally hardcode their modes in the driver as opposed to reading EDID. If a panel does need to read EDID, it should be responsible for ensuring it's in a state in which it can. Signed-off-by: Sean Paul

drm/bridge: analogix_dp: Don't read EDID if panel present

2016-09-24T06:26:34Z

If there's a panel connected to the analogix_dp bridge, rely on the panel driver for modes, rather than reading EDID *and* calling get_modes() on the panel. This allows panels with a valid EDID to read it in the panel driver (e.g. simple_panel), and panels with invalid EDID to homebrew modes in their get_modes implementation. Signed-off-by: Sean Paul

drm/bridge: analogix_dp: Remove duplicated code

2016-09-24T06:26:34Z

Remove code for reading the EDID and DPCD fields and use the helpers instead. Besides the obvious code reduction, other helpers are being added to the core that could be used in this driver and will be good to be able to use them instead of duplicating them.
