This driver will support dp_intf and there are many configs between dpi and dp_intf. Therefore, we will add many configs in "struct mtk_dpi_conf". To let this structure more readable, we add this kernel doc. Signed-off-by:

The compatible “mediatek,mt8192-disp-rdma” is being used for reading the data into DMA for back-end panel driver in mt8192 but there is no difference between mt8183 and mt8192 in rdma driver. Remove compatible “mediatek,mt8192-disp-rdma” from the driver and should use “mediatek,mt8183-disp-rdma” as fallback in 8192 DTS according to the mediatek,rdma.yaml. Signed-off-by:

In the dsi_enable function, mtk_dsi_rxtx_control is to pull up the MIPI signal operation. Before dsi_disable, MIPI should also be pulled down by writing a register instead of disabling dsi. If disable dsi without pulling the mipi signal low, the value of the register will still maintain the setting of the mipi signal being pulled high. After resume, even if the mipi signal is not pulled high, it will still be in the high state.

To comply with the panel sequence, hold the mipi signal to LP00 before the dcs cmds transmission, and pull the mipi signal high from LP00 to LP11 until the start of the dcs cmds transmission. The normal panel timing is : (1) pp1800 DC pull up (2) avdd & avee AC pull high (3) lcm_reset pull high -> pull low -> pull high (4) Pull MIPI signal high (LP11) -> initial code -> send video data (HS mode) The power-off sequence is reversed. If dsi is not in cmd mode, then dsi will pull the mipi signal high in the mtk_output_dsi_enable function. The delay in lane_ready func is the reaction time of dsi_rx after pulling up the mipi signal.

In order to match the changes of "Use the drm_panel_bridge API", the poweron/poweroff of dsi is extracted from enable/disable and defined as new funcs (atomic_pre_enable/atomic_post_disable). Since dsi_poweron is moved from dsi_enable to pre_enable function, in order to avoid poweron failure, the operation of dsi register fails to cause bus hang. Therefore, the protection mechanism is added to the dsi_enable function.

The bluetooth code uses our bitmap infrastructure for the two bits (!) of connection setup flags, and in the process causes odd problems when it converts between a bitmap and just the regular values of said bits. It's completely pointless to do things like bitmap_to_arr32() to convert a bitmap into a u32. It shoudln't have been a bitmap in the first place. The reason to use bitmaps is if you have arbitrary number of bits you want to manage (not two!), or if you rely on the atomicity guarantees of the bitmap setting and clearing. The code could use an "atomic_t" and use "atomic_or/andnot()" to set and clear the bit values, but considering that it then copies the bitmaps around with "bitmap_to_arr32()" and friends, there clearly cannot be a lot of atomicity requirements. So just use a regular integer. In the process, this avoids the warnings about erroneous use of bitmap_from_u64() which were triggered on 32-bit architectures when conversion from a u64 would access two words (and, surprise, surprise, only one word is needed - and indeed overkill - for a 2-bit bitmap). That was always problematic, but the compiler seems to notice it and warn about the invalid pattern only after commit 0a97953f ("lib: add bitmap_{from,to}_arr64") changed the exact implementation details of 'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.
