Our probe() function never enabled this clock, so we shouldn't disable it if we fail to probe the bridge. Noted by inspection. Fixes: 2d4f7bda ("drm/rockchip: dsi: migrate to use dw-mipi-dsi bridge driver") Signed-off-by:

Since commit 43c2de10 ("drm/rockchip: dsi: move all lane config except LCDC mux to bind()"), we perform most HW configuration in the bind() function. This configuration may be lost on suspend/resume, so we need to call it again. That may lead to errors like this after system suspend/resume: dw-mipi-dsi-rockchip ff968000.mipi: failed to write command FIFO panel-kingdisplay-kd097d04 ff960000.mipi.0: failed write init cmds: -110 Tested on Acer Chromebook Tab 10 (RK3399 Gru-Scarlet). Note that early mailing list versions of this driver borrowed Rockchip's downstream/BSP solution, to do HW configuration in mode_set() (which *is* called at the appropriate pre-enable() times), but that was discarded along the way. I've avoided that still, because mode_set() documentation doesn't suggest this kind of purpose as far as I can tell.

In commit 43c2de10 ("drm/rockchip: dsi: move all lane config except LCDC mux to bind()"), we moved most HW configuration to bind(), but we didn't move the runtime PM management. Therefore, depending on initial boot state, runtime-PM workqueue delays, and other timing factors, we may disable our power domain in between the hardware configuration (bind()) and when we enable the display. This can cause us to lose hardware state and fail to configure our display. For example: dw-mipi-dsi-rockchip ff968000.mipi: failed to write command FIFO panel-innolux-p079zca ff960000.mipi.0: failed to write command 0 or: dw-mipi-dsi-rockchip ff968000.mipi: failed to write command FIFO panel-kingdisplay-kd097d04 ff960000.mipi.0: failed write init cmds: -110 We should match the runtime PM to the lifetime of the bind()/unbind() cycle. Tested on Acer Chrometab 10 (RK3399 Gru-Scarlet), with panel drivers built either as modules or built-in. Side notes: it seems one is more likely to see this problem when the panel driver is built into the kernel. I've also seen this problem bisect down to commits that simply changed Kconfig dependencies, because it changed the order in which driver init functions were compiled into the kernel, and therefore the ordering and timing of built-in device probe.

If hardware is malfunctioning (e.g., misconfigured clocks?), we can get stuck here forever, holding various DRM locks and eventually locking up the entire system. It's better to complain loudly and move on, than to lock up the system. In local tests, this operation takes less than 20ms. Signed-off-by:

It adds a DRM panel driver for Sony Tulip Truly NT35521 5.24" 1280x720 DSI panel, which can be found on Sony Xperia M4 Aqua phone. The panel backlight is managed through DSI link. The driver is built using linux-mdss-dsi-panel-driver-generator[1], and additionally modeling the 5V control GPIOs with regulators and adding Backlight GPIO support.

The nt35950 IC from Novatek is a Driver IC used to drive MIPI-DSI panels, with Static RAM for content retention in command mode and also supports video mode with VESA Frame Buffer Compression or Display Stream Compression on single, or dual dsi port(s). This DDIC is also capable of upscaling an input image to the panel's native resolution, for example it can upscale a 1920x1080 input to 3840x2160 with either bilinear interpolation or pixel duplication.

Current code always sets reset line low in .pre_enable callback and holds it low for 10ms. This is sub-optimal and increases the time between enablement of the DSI83 and valid LVDS clock. Rework the reset handling such that the reset line is held low for 10ms both in probe() of the driver and .disable callback, which guarantees that the reset line was always held low for more than 10ms and therefore the reset line timing requirement is satisfied. Furthermore, move the reset handling into .enable callback so the entire DSI83 initialization is now in one place. This reduces DSI83 enablement delay by up to 10ms. Signed-off-by:
