The pwr_on_vary_bl_to_blon is set one unit per 4ms. BUG=b:271704149 TEST=Build; Verify the UPD was pass to system integrated table; measure the power on sequence on whiterun Signed-off-by: Chris.Wang Change-Id: I25c9f962e70f599c780259f0943a03f8aa7cbfd1 Reviewed-on: https://review.coreboot.org/c/coreboot/+/73752 Tested-by: build bot (Jenkins) Reviewed-by: Jason Glenesk --- src/soc/amd/mendocino/chip.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/soc/amd/mendocino/chip.h') diff --git a/src/soc/amd/mendocino/chip.h b/src/soc/amd/mendocino/chip.h index f16f5fd4be..774ce5ea59 100644 --- a/src/soc/amd/mendocino/chip.h +++ b/src/soc/amd/mendocino/chip.h @@ -177,6 +177,10 @@ struct soc_amd_mendocino_config { /* Force USB3 port to gen1, bit0 - controller0 Port0, bit1 - Port1 */ union usb3_force_gen1 usb3_port_force_gen1; + /* Set for eDP power sequence adjustment timing from varybl to blon.
