As is quite common, some of TC358768's PLL register fields are to be programmed with (value - 1). Specifically, the FBD and PRD, multiplier and divider, are such fields. However, what the driver currently does is that it considers that the formula used for PLL rate calculation is: RefClk * [(FBD + 1)/ (PRD + 1)] * [1 / (2^FRS)] where FBD and PRD are values directly from the registers, while a more sensible way to look at it is: RefClk * FBD / PRD * (1 / (2^FRS)) and when the FBD and PRD values are written to the registers, they will be subtracted by one. Change the driver accordingly, as it simplifies the PLL code. Reviewed-by:

The driver has a few places where it does: if (thing_is_enabled_in_config) update_thing_bit_in_hw() This means that if the thing is _not_ enabled, the bit never gets cleared. This affects the h/vsyncs and continuous DSI clock bits. Fix the driver to always update the bit. Fixes: ff1ca639 ("drm/bridge: Add tc358768 driver") Reviewed-by:

As the TC358768 is a DPI to DSI bridge, the DSI side does not need to define h/v sync polarities. This means that sometimes we have a mode without defined sync polarities, which does not work on the DPI side. Add a mode_fixup hook to default to positive sync polarities. Reviewed-by:

smatch reports: drivers/gpu/drm/bridge/tc358768.c:223 tc358768_update_bits() error: uninitialized symbol 'orig'. Fix this by bailing out from tc358768_update_bits() if the tc358768_read() produces an error. Fixes: ff1ca639 ("drm/bridge: Add tc358768 driver") Reviewed-by:

This is presently unused on HW, we read a bunch of regs and calculate the watermark during the second supervisor interrupt. I don't want to change this yet as I need to re-remember how older HW works exactly, but RM wants this info via RPC. Signed-off-by:
