mb/purism/librem_14: Update GPIO config
Update GPIO config based on review of latest schematics: - LAN/WLAN reset lines are NC - SDIO lines configured via GPP_G0-G7 - DMIC lines are wired directly to codec, not PCH, so GPP_D17-20 are set to NC - Pads GPP_H0-H3 are configured for I2S2 - Pads GPP_H7-H9 are straps for board revision, so treated as GPI - CPU_C10_GATE# is NC - PWRBTN# does not need an internal pull-up - GPP_C20-23 are configured for M.2 UART - SATAXPCIE1/2 and EC SCI/SMI lines do not need internal pull ups - GPP_C6/C7 set to I2C1 for future use - GPP_E15 changed from SCI to SMI, edge triggered Change-Id: If113cfeadf093e10dd84ab827ead594088f02ba1 Signed-off-by: Matt DeVillier <matt.devillier@puri.sm> Reviewed-on: https://review.coreboot.org/c/coreboot/+/52389 Reviewed-by: Michael Niewöhner <foss@mniewoehner.de> Reviewed-by: Angel Pons <th3fanbus@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
