2022-01-04drm/bridge: anx7625: Fix null vs IS_ERR() checking in ↵Miaoqian Lin
anx7625_register_i2c_dummy_clients Since i2c_new_client_device() function return error pointers. The i2c_new_dummy_device() function does not return NULL, It returns error pointers too. Using IS_ERR() to check the return value to fix this.

2022-01-04drm/stm: dsi: provide the implementation of mode_valid()Antonio Borneo
The dsi has several constraints on the video modes it can support, mainly due to the frequencies that can be generated by the PLL integrated in the DSI device. Verify that the required HS clock can be generated by the PLL. The dsi clock from the dsi PLL and the ltdc pixel clock are asynchronous. The dsi needs to return in LP mode during HFP or HBP to re-synchronize at each video line. Verify that the duration of HFP and HBP allows the dsi to enter in LP mode.

Add XRGB8888 emulation support for devices that can only do XRGB2101010. This is chiefly useful for simpledrm on Apple devices where the bootloader-provided framebuffer is 10-bit.

2021-12-16of: Move simple-framebuffer device handling from simplefb to ofHector Martin
This code is required for both simplefb and simpledrm, so let's move it into the OF core instead of having it as an ad-hoc initcall in the drivers.

The OnSemi FIN3385 Parallel-to-LVDS encoder has a dedicated input line to select input pixel data sampling edge. Add DT property "pclk-sample", not the same as the one used by display timings but rather the same as used by media, and configure bus flags based on this DT property.
