2019-04-08drm/i915: Get power refs in encoder->get_power_domains()Imre Deak4-38/+35
Push getting the reference for the encoders' power domains into the encoder get_power_domains() hook instead of doing this from the caller. This way the encoder can store away the corresponding wakerefs. This fixes the DSI encoder disabling, which didn't release these power references it acquired during HW state readout. Note that longtime ownership for the corresponding wakerefs can be thus acquired / released in two ways. Nevertheless there is always only one owner for them: After HW readout (booting/system resume): - encoder->get_power_domains() acquires - encoder->disable*() releases After a modeset (calling intel_atomic_commit()): - encoder->enable*() acquires - encoder->disable*() releases * can be any of the encoder enable/disable hooks. v2: - Check that the DSI io_wakerefs are unset both during encoder HW readout and enabling.

2019-04-08drm/i915: Fix pipe_bpp readout for BXT/GLK DSIVille Syrjälä1-0/+24
The only bpc information in pipe registers for BXT/GLK DSI is the PIPEMISC dither bpc. Let's try to use that to read out pipe_bpp on these platforms. However, I'm not sure if this will be correctly populated by the GOP since bspec suggests it's only needed if dithering is actually enabled. If not I guess we'll have to go one step further and extract pipe_bpp from the DSI pixel format when dithering is disabled.

2019-04-08drm/amd/display: Fix negative cursor pos programming (v2)Nicholas Kazlauskas1-21/+2
[Why] If the cursor pos passed from DM is less than the plane_state->dst_rect top left corner then the unsigned cursor pos wraps around to a large positive number since cursor pos is a u32. There was an attempt to guard against this in hubp1_cursor_set_position by checking the src_x_offset and src_y_offset and offseting the cursor hotspot within hubp1_cursor_set_position. However, the cursor position itself is still being programmed incorrectly as a large value. This manifests itself visually as the cursor disappearing or containing strange artifacts near the middle of the screen on raven. [How] Don't subtract the destination rect top left corner from the pos but add it to the hotspot instead. This happens before the pos gets passed into hubp1_cursor_set_position. This achieves the same result but avoids the subtraction wrap around. With this fix the original cursor programming logic can be used again. v2: add hunk that got dropped accidently when this patch was originally committed.

2019-03-27drm/omap: hdmi4_cec: Fix CEC clock handling for PMTony Lindgren1-7/+19
If CONFIG_OMAP4_DSS_HDMI_CEC is enabled in .config, deeper SoC idle states are blocked because the CEC clock gets always enabled on init. Let's fix the issue by moving the CEC clock handling to happen later in hdmi_cec_adap_enable() as suggested by Hans Verkuil <hverkuil@xs4all.nl>. This way the CEC clock gets only enabled when needed. This can be tested by doing cec-ctl --playback to enable the CEC, and doing cec-ctl --clear to disable it. Let's also fix the typo for "divider" in the comments while at it.
