2022-02-07treewide: Remove "ERROR: "/"WARN: " prefixes from log messagesJulius Werner
Now that the console system itself will clearly differentiate loglevels, it is no longer necessary to explicitly add "ERROR: " in front of every BIOS_ERR message to help it stand out more (and allow automated tooling to grep for it). Removing all these extra .rodata characters should save us a nice little amount of binary size. This patch was created by running find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';' and doing some cursory review/cleanup on the result. Then doing the same thing for BIOS_WARN with 's/printk\(\s*BIOS_WARNING,\s*"WARN(ING)?: /printk\(BIOS_WARNING, "/gi' Signed-off-by: Julius Werner <jwerner@chromium.org> Change-Id: I3d0573acb23d2df53db6813cb1a5fc31b5357db8 Reviewed-on: https://review.coreboot.org/c/coreboot/+/61309 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr> Reviewed-by: Lance Zhao Reviewed-by: Jason Glenesk <jason.glenesk@gmail.com>

2021-12-02drivers/analogix/anx7625: Fix edid_read()Yu-Ping Wu
The current implementations of edid_read() and segments_edid_read() have a few problems: 1. The type of variable `c` is incorrect, not matching the return type of sp_tx_aux_rd(). In addition, the meaning of `c` is unknown. 2. It is pointless to do `cnt++` when sp_tx_aux_rd() fails. 3. These two functions ignore the return value of anx7625_reg_block_read(). 4. In segments_edid_read(), anx7625_reg_write() might return a positive value on failure. Fix all of the 4 issues, and modify the code to be closer to kernel 5.10's implementation (drivers/gpu/drm/bridge/analogix/anx7625.c). Note that, however, unlike in kernel, anx7625_reg_block_read() here doesn't return the number of bytes. On success, 0 is returned instead. In addition, following coreboot's convention, always return negative error codes. In particular, change the return value to -1 for edid_read() and segments_edid_read() on failure.

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.
