mb/lenovo/t420: Copy HDA verbs from vendor firmware
Background story (I think that's what great in opensource - ppl leave there part of their lives): ;-) While trying to fix audio jack not working with coreboot and Windows 10 with some help from hell__ and nico_h on IRC nico_h discovered that t420 and t430 hda_verb.c are the same: <nico_h> oddly, in coreboot source T420 and T430 have the same numbers for very different codecs... I suspect copy-pasta Difference between /sys/class/sound/cardX/hwCXDY/init_pin_config in vendor BIOS helped with the updated config. Connecting audio jack now works flawless both in Linux and Windows. Audio-related keyboard buttons: volup, voldown, mute works fine both in Linux (Debian-based) and Windows 10. mutemic button works (tested ie. with xev) but both in Linux and Windows 10 wont light up or makes any effect. +-----------------------------------+ | init_pin_config dump from: | +----= VENDOR =---+---= coreboot =--+ | 0x19 0x04211040 | 0x19 0x04211040 | | 0x1a 0x61a19050 | 0x1a 0x61a19050 | | 0x1b 0x04a11060 | 0x1b 0x04a11060 | | 0x1c 0x6121401f | 0x1c 0x6121401f | | 0x1d 0x40f001f0 | 0x1d 0x40f001f0 | | 0x1e 0x40f001f0 | 0x1e 0x40f001f0 | | 0x1f 0x90170110 | 0x1f 0x90170110 | | 0x20 0x40f001f0 | 0x20 0x40f001f0 | | 0x22 0x40f001f0 | 0x22 0x40f001f0 | | 0x23 0x90a60170 | 0x23 0x90a60170 | +-----------------+-----------------+ Tested-by: Piotr Szymaniak Signed-off-by: Piotr Szymaniak <szarpaj@grubelek.pl> Change-Id: Ie5eba84e5ea590b7db00e189cd68e714bee7e410 Reviewed-on: https://review.coreboot.org/c/coreboot/+/51612 Reviewed-by: Angel Pons <th3fanbus@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
