If I'm not wrong, we discussed about tcon_dclk (PLL_MIPI) last week
[1] and these burst changes between 01/23 to 09/23 which are generic
changes to DSI and not related to clock. Apart from that I made few
changes on commit logs between the versions (which I was mentioned on
the cover-letter patch). If any issues issues on commit message,
please let me know so-that I can rework.
