Platform drivers now have the option to have the platform core create and remove any needed sysfs attribute files. So take advantage of that and do not register "by hand" a sysfs file.

'exynos_dsi_parse_dt()' takes a reference to 'dsi->in_bridge_node'. This must be released in the error handling path. In order to do that, add an error handling path and move the 'exynos_dsi_parse_dt()' call from the beginning to the end of the probe function to ease the error handling path. This function only sets some variables which are used only in the 'transfer' function. The call chain is: .transfer --> exynos_dsi_host_transfer --> exynos_dsi_init --> exynos_dsi_enable_clock (use burst_clk_rate and esc_clk_rate) --> exynos_dsi_set_pll (use pll_clk_rate) While at it, also handle cases where 'component_add()' fails. This patch is similar to commit 70505c2e ("drm/exynos: dsi: Remove bridge node reference in removal") which fixed the issue in the remove function.

Runtime power management is essential for the Exynos Mixer driver operation. It should be enabled before adding its DRM component, because in some cases (when deferred probe takes place due to the IOMMU availability) the DRM driver might be initialized directly from the Mixer's component_add() call, what results in starting the driver operation without enabling the runtime power management.

Internal pages array and scatter-list for them is not really needed for anything. FBDev emulation can simply rely on the DMA-mapping framework to create a proper kernel mapping for the buffer, while all other buffer use cases don't really need that array at all. Suggested-by:

According to drm_plane_create_zpos_property() function documentation, all planes zpos range should be set if zpos property is supported. However, the rcar-du driver didn't set primary plane zpos range. Since the primary plane's zpos is fixed, set it immutably. Reported-by:

The simple-bridge driver supports multiple simple or dumb bridges, covered by different compatible strings but otherwise identical DT bindings. Some of those bridges have undocumented bindings, while others are documented in text form in separate files. Group them all in a single binding and convert it to YAML. The psave-gpios property of the adi,adv7123 is dropped, as it isn't supported by the driver and isn't specified in any DT file upstream. Support for power saving is available through the enable-gpios property that should cover all the needs of the ADV7123 (as the device only has a /PSAVE pin and no enable pin). Signed-off-by:

People use panel-simple when they have panels that are builtin to their device. In these cases the HPD (Hot Plug Detect) signal isn't really used for hotplugging devices but instead is used for power sequencing. Panel timing diagrams (especially for eDP panels) usually have the HPD signal in them and it acts as an indicator that the panel is ready for us to talk to it. Sometimes the HPD signal is hooked up to a normal GPIO on a system. In this case we need to poll it in the correct place to know that the panel is ready for us. In some system designs the right place for this is panel-simple. When adding this support, we'll account for the case that there might be a circular dependency between panel-simple and the provider of the GPIO. The case this was designed for was for the "ti-sn65dsi86" bridge chip. If HPD is hooked up to one of the GPIOs provided by the bridge chip then in our probe function we'll always get back -EPROBE_DEFER. Let's handle this by allowing this GPIO to show up late if we saw -EPROBE_DEFER during probe. NOTE: since the gpio_get_optional() is used, if the "hpd-gpios" isn't there our variable will just be NULL and we won't do anything in prepare(). Signed-off-by:

The BOE NV133FHM-N61 is documented in the original commit to be a 13.3" panel, but the size listed in our struct doesn't match. Specifically: math.sqrt(30.0 * 30.0 + 18.7 * 18.7) / 2.54 ==> 13.92 Searching around on the Internet shows that the size that was in the structure was the "Outline Size", not the "Display Area". Let's fix it. Also the Internet says that this panel supports 262K colors. That's 6bpp, not 8bpp. Fixes: b0c664cc ("panel: simple: Add BOE NV133FHM-N61") Signed-off-by:
