2018-07-10drm/panel: Make of_drm_find_panel() return an ERR_PTR() instead of NULLBoris Brezillon1-1/+1
Right now, the DRM panel logic returns NULL when a panel pointing to the passed OF node is not present in the list of registered panels. Most drivers interpret this NULL value as -EPROBE_DEFER, but we are about to modify the semantic of of_drm_find_panel() and let the framework return -ENODEV when the device node we're pointing to has a status property that is not equal to "okay" or "ok". Let's first patch the of_drm_find_panel() implementation to return ERR_PTR(-EPROBE_DEFER) instead of NULL and patch all callers to replace the '!panel' check by an 'IS_ERR(panel)' one.

2017-03-01drm/rockchip: dw-mipi-dsi: improve PLL configurationJohn Keeping1-1/+12
The multiplication ratio for the PLL is required to be even due to the use of a "by 2 pre-scaler". Currently we are likely to end up with an odd multiplier even though there is an equivalent set of parameters with an even multiplier. For example, using the 324MHz bit rate with a reference clock of 24MHz we end up with M = 27, N = 2 whereas the example in the PHY databook gives M = 54, N = 4 for this bit rate and reference clock. By walking down through the available multiplier instead of up we are more likely to hit an even multiplier. With the above example we do now get M = 54, N = 4 as given by the databook. While doing this, change the loop limits to encode the actual limits on the divisor, which are: 40MHz >= (pllref / N) >= 5MHz Signed-off-by: John Keeping <john@metanate.com> Reviewed-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Sean Paul <seanpaul@chromium.org> Link: http://patchwork.freedesktop.org/patch/msgid/20170224125506.21533-18-john@metanate.com

2017-03-01drm/rockchip: dw-mipi-dsi: don't configure hardware in mode_set for MIPIJohn Keeping1-28/+21
With atomic modesetting the hardware will be powered off when the mode_set function is called. We should configure the hardware in the enable function, which is the atomic version of "commit" so let's use the enable hook rather than commit while we're at it.

2016-12-01drm: Make the connector .detect() callback optionalLaurent Pinchart1-7/+0
Many drivers (21 to be exact) create connectors that are always connected (for instance to an LVDS or DSI panel). Instead of forcing them to implement a dummy .detect() handler, make the callback optional and consider the connector as always connected in that case.

All outputs have a 1:1 relationship between connectors and encoders and the driver is relying on the atomic helpers: we can drop the custom ->best_encoder() implementations and let the core call drm_atomic_helper_best_encoder() for us.
