Revert "drm/bridge: lt9611: Do not generate HFP/HBP/HSA and EOT packet" This reverts commit 8ddce13ae696 ("drm/bridge: lt9611: Do not generate HFP/HBP/HSA and EOT packet") to fix display regression on the Dragonboard 845c (SDM845) devboard. There's a mismatch on the real action of the following flags: - MIPI_DSI_MODE_VIDEO_NO_HSA - MIPI_DSI_MODE_VIDEO_NO_HFP - MIPI_DSI_MODE_VIDEO_NO_HBP which leads to a non-working display on qcom platforms.

i2c: Make remove callback return void The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

drm/bridge: lt9611: Use both bits for HDMI sensing In commit 19cf41b64e3b ("lontium-lt9611: check a different register bit for HDMI sensing"), the bit flag used to detect HDMI cable connect was switched from BIT(2) to BIT(0) to improve compatibility with some monitors that didn't seem to set BIT(2). However, with that change, I've seen occasional issues where the detection failed, because BIT(2) was set, but not BIT(0). Unfortunately, as I understand it, the bits and their function was never clearly documented. So lets instead check both (BIT(2) | BIT(0)) when checking the register.

lontium-lt9611: check a different register bit for HDMI sensing It has been observed that with certain monitors such as the HP Z27n, the register 0x825e reads a value of 0x79 when the HDMI cable is connected and 0x78 when it is disconnected, i.e. bit 0 appears to correspond to the HDMI connection status and bit 2 is never set. Therefore, change the driver to check bit 0 instead of bit 2.

drm/bridge: lt9611: Register and attach our DSI device at probe In order to avoid any probe ordering issue, the best practice is to move the secondary MIPI-DSI device registration and attachment to the MIPI-DSI host at probe time.
