drm/mediatek: dpi: Remove output format of YUV

2022-08-25T09:15:05+00:00

[ Upstream commit c9ed0713b3c35fc45677707ba47f432cad95da56 ] DPI is not support output format as YUV, but there is the setting of configuring output YUV. Therefore, remove them in this patch.

drm/mediatek: Add pull-down MIPI operation in mtk_dsi_poweroff function

2022-08-25T09:15:04+00:00

[ Upstream commit fa5d0a0205c34734c5b8daa77e39ac2817f63a10 ] In the dsi_enable function, mtk_dsi_rxtx_control is to pull up the MIPI signal operation. Before dsi_disable, MIPI should also be pulled down by writing a register instead of disabling dsi. If disable dsi without pulling the mipi signal low, the value of the register will still maintain the setting of the mipi signal being pulled high. After resume, even if the mipi signal is not pulled high, it will still be in the high state.

drm/mediatek: Fix mtk_cec_mask()

[ Upstream commit 2c5d69b0a141e1e98febe3111e6f4fd8420493a5 ] In current implementation, mtk_cec_mask() writes val into target register and ignores the mask. After talking to our hdmi experts, mtk_cec_mask() should read a register, clean only mask bits, and update (val | mask) bits to the register.

drm/mediatek: Add missing put_device() call in mtk_hdmi_dt_parse_pdata()

[ Upstream commit 0680a622318b8d657323b94082f4b9a44038dfee ] if of_find_device_by_node() succeed, mtk_drm_kms_init() doesn't have a corresponding put_device().

drm/mediatek: handle events when enabling/disabling crtc

[ Upstream commit 411f5c1eacfebb1f6e40b653d29447cdfe7282aa ] The driver currently handles vblank events only when updating planes on an already enabled CRTC. The atomic update API however allows requesting an event when enabling or disabling a CRTC. This currently leads to event objects being leaked in the kernel and to events not being sent out. Fix it.

drm/mediatek: mtk_drm_drv.c: Add of_node_put() before goto

2019-09-19T07:09:39+00:00

commit 165d42c012be69900f0e2f8545626cb9e7d4a832 upstream. Each iteration of for_each_child_of_node puts the previous node, but in the case of a goto from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the goto in two places. Issue found with Coccinelle.
