PMS_P value set in sec_mipi_dsim_check_pll_out using PLLCTRL_SET_P()
with offset 13 and then an additional offset of one bit added in
sec_mipi_dsim_config_pll via PLLCTRL_SET_PMS().
Please check this for additional information
https://github.com/fschrempf/linux/commit/bbb3549a99e162ef6ad4c83d5fd4d39a6daa6d56
I'll update the additional information in commit messages in v5.
Thanks,
Jagan.
