Subject: [PATCH v4 0/5] drm/mxsfb: Fix runtime PM for unpowering lcdif block
Date: Wed, 8 Aug 2018 19:08:57 +0300 [thread overview]
Message-ID: <cover.1533743954.git.leonard.crestez@nxp.com> (raw)
Adding lcdif nodes to a power domain currently does work, it results in
black/corrupted screens or hangs. While the driver does enable runtime
pm it does not deal correctly with the block being unpowered.
Changes since v3:
* Don't set initial fb in mode_set_nofb, do it in crtc_enable
* Simplify AXI clk handling to allow setting fb in crtc_enable
* No functional changes
Last 3 patches are identical to v3 with review tags attached.
Link to v3: https://lkml.org/lkml/2018/8/6/728
Leonard Crestez (5):
drm/mxsfb: Move axi clk enable/disable to crtc enable/disable
drm/mxsfb: Fix initial corrupt frame when activating display
drm/mxsfb: Add pm_runtime calls to pipe_enable/disable
drm/mxsfb: Add PM_SLEEP support
drm/mxsfb: Switch to drm_atomic_helper_commit_tail_rpm
