drm: drop _mode_ from drm_mode_connector_attach_encoder

2018-07-13T16:40:27Z

Again to align with the usual prefix of just drm_connector_. Again done with sed + manual fixup for indent issues. Reviewed-by: Sean Paul Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20180709084016.23750-7-daniel.vetter@ffwll.ch

drm: add missing ctx argument to plane transitional helpers

2018-07-03T07:30:19Z

In commits: 34a2ab5e0689 ("drm: Add acquire ctx parameter to ->update_plane") 1931529448bc ("drm: Add acquire ctx parameter to ->plane_disable") a pointer to a drm_modeset_acquire_ctx structure was added as an argument to the method prototypes. The transitional helpers are supposed to be directly plugged in as implementations of these methods, but doing so generates a warning. Add the missing argument. A number of buggy users were added for drm_plane_helper_disable() which need to be fixed up for this change, which we do by passing a NULL ctx argument.

drm/arc: Stop consulting plane->fb

2018-05-25T17:08:27Z

We want to stop using plane->fb with atomic driver, so stop looking at it. I have no idea what this code is trying to achieve. There is no corresponding check in the enable path. Also since arc_pgu_set_pxl_fmt() will anyway oops if there is no fb I'm going to assuming that I can just remove the check entirely. There seems to be a general shortage of .atomic_check() in this driver...

drm/arcpgu: remove drm_encoder_slave

2018-01-30T17:05:25Z

drm_encoder_slave is the old way to write bridge drivers, for i2c bridges only. It's deprecated, and definitely should not be used in new drivers. This has absolutely nothing to do with the new bridge driver infrastructure implemented by drm_bridge. What's even strange is that arcpgu doesn't even use any of this, it really only wants a plain normal drm_encoder. Nuke all the surplus real estate. v2: Actually git add after compile testing ... v3: Clarify commit message and stop including drm_encoder_slave.h.

drm: arcpgu: Allow some clock deviation in crtc->mode_valid() callback

2017-08-02T21:11:02Z

Currently we expect that clock driver produces the exact same value as we are requiring. There can, and will, be some deviation however so we need to take that into account instead of just rejecting the mode. According to the HDMI spec we have a max of +-0.5% for the pixel clock frequency deviation. Lets take that into an advantage and use it to calculate how much deviation we can support.
