2025-03-06soc: mediatek: mtk-mutex: Add DPI1 SOF/EOF to MT8188 mutex tablesAngeloGioacchino Del Regno
MT8188 uses DPI1 to output to the HDMI controller: add the Start of Frame and End of Frame configuration for the DPI1 IP to the tables to unblock generation and sending of these signals to the GCE.

2024-07-30soc: mediatek: mtk-mutex: Reduce type size for mtk_mutex_data membersAngeloGioacchino Del Regno
All of mutex_mod and mutex_table_mod contain an array of bit numbers, which can go from 0 to 63, it is hence not needed to use an unsigned 32-bits integer to store that: change them to unsigned 8-bits instead. As for the mutex_sof table since this directly contains the values to write to the DISP_MUTEXn_CTL register, which has only bits [13:0] (so this register is effectively 14 bits long), change that to use unsigned 16-bits. The type of mutex_{mod,sof}_reg was also changed to 16 bits, as the maximum value that those will ever have is 0x800, because it calculates as 0x30 + (0x20 * n) where n's maximum value is 63. This reduces module size and brings no functional changes.

2023-08-12soc: mediatek: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
