The Raspberry Pi 7" 800x480 panel uses a Toshiba TC358762 DSI to DPI bridge chip, so there is a requirement for the timings to be specified for the end panel. Add such a definition. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com> drm/panel-simple: Populate bpc when using panel-dpi panel-dpi doesn't know the bit depth, so in the same way that DPI is guessed for the connector type, guess that it'll be 8bpc. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com> drm/panel-simple: Allow the bus format to be read from DT for panel-dpi The "panel-dpi" compatible string configures panel from device tree, but it doesn't provide any way of configuring the bus format (colour representation), nor does it populate it. Add a DT parameter "bus-format" that allows the MEDIA_BUS_FMT_xxx value to be specified from device tree. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com> drm/panel: simple: add Geekworm MZP280 Panel Add support for the Geekworm MZP280 Panel Signed-off-by: Chris Morgan <macromorgan@hotmail.com> Acked-by: Maxime Ripard <maxime@cerno.tech> drm/panel: simple: Add Innolux AT056tN53V1 5.6" VGA Add support for the Innolux AT056tN53V1 5.6" VGA (640x480) TFT LCD panel. Signed-off-by: Joerg Quinten <aBUGSworstnightmare@gmail.com> Signed-off-by: Phil Elwell <phil@raspberrypi.com> drm/panel: simple: Alter the timing for the Pi 7" DSI display vc4 has always fixed up the timing, so the values defined have never actually appeared on the wire. The display appears to want a slightly longer HFP, so extend the timings and recompute the clock to give the same frame rate. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com> drm/panel: add panel-dsi Equivalent to panel-dpi for configuring a simple DSI panel with device tree side timings and bus settings. Motiviation is the same as for panel-dpi of wanting to support new simple panels without needing to patch the kernel. Signed-off-by: Timon Skerutsch <kernel@diodes-delight.com> drm/panel-simple: Remove custom handling of orientation The framework now handles reading orientation from DT, therefore remove the custom get_orientation hook from panel-simple. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com> drm/panel-simple: Fix 7inch panel mode for misalignment The 7inch panel is one line off the screen both horizontally and vertically. Alter the panel mode to correct this. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com> drm/panel-simple: Increase pixel clock on Pi 7inch panel The Toshiba bridge is very fussy and doesn't like the CM3 output when being told to produce a 27.777MHz pixel clock, which is an almost perfect match to the DSI link integer divider. Increasing to 30MHz will switch the DSI link from 333MHz to 400MHz and makes the bridge happy with the same video timing as works on Pi4. (Pi4 will be using a link frequency of 375MHz due to a 3GHz parent PLL). Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>

这个驱动是结合树莓派内核源码+邮件列表（他们之中单拎出来一个在主线都不能用），独立新创建的驱动，所以可能git不好溯源，我补一下版权信息吧

声卡实现方案还不确定，所以可能先不动，后期再改
