Some bridges, such as the TI SN65DSI83, require the HS clock to be

Without this change, the bridge gives the following error:
sn65dsi83 14-002c: failed to lock PLL, ret=-110
sn65dsi83 14-002c: Unexpected link status 0x01
sn65dsi83 14-002c: reset the pipe
Move the necessary functions from enable to pre-enable.

Hi
I have run into the same problem, but in combination with another
pipeline. I am seeing same problem with an i.MX8 using the nwl-dsi
bridge and the dcss driver.
I have submitted a fix that adresses the problem in the ti-sn65dsi83
driver instead. With a bit of luck, it can replace the fix proposed in
this thread.

That clarifies a lot of things.
The patch on mtk_dsi shall be reverted then.
Cheers,
Angelo
