2021-09-13drivers/analogix/anx7625: prevent video clock jitter on IVO panelsXin Ji
The MIPI source video data has a large variation (e.g. 59Hz ~ 61Hz), anx7625 defines K ratio for matching MIPI input video clock and DP output video clock. A bigger k value can match a bigger video data variation. IVO panel has smaller variation than DP CTS spec, so decrease k value to 0x3b.

2020-03-17src (minus soc and mainboard): Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2020-02-17soc/mediatek: dsi: reduce the hbp and hfp for phy timingJitao Shi
The extra data transfer in DSI, namely, lpx, hs_prepare, hs_zero, hs_exit and the sof/eof of DSI packets, will enlarge the line time, which causes the real frame on dsi bus to be lower than the one calculated by video timing. Therefore, hfp_byte is reduced by d_phy to compensate the increase in time by the extra data transfer. However, if hfp_byte is not large enough, the hsync period will be increased on DSI data, leading to display scrolling in firmware screen. To avoid this situation, this patch changes the DSI Tx driver to reduce both hfp_byte and hbp_byte, with the amount proportional to hfp and hbp, respectively. Refer to kernel's change in CL:1915442. Also rename 'phy_timing' to 'timing' to sync with kernel upstream. Since the phy timing initialization sequence has been corrected, the m value adjustment in the analogix driver can be removed.
