From f9da70618e8d6d05aa6e8ae92479e5fc3764d7bd Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Tue, 4 Jun 2013 10:06:25 -0700 Subject: [PATCH] slippy/falco/peppy: Fix Chrome OS GPIO export in ACPI The OIPG package needs to have >1 member to make the chromeos_acpi kernel driver do the right automagic sysfs topology creation. Additionally an "unimplemented" GPIO should be reported as 0xFF because 0 is a valid GPIO number. verify crossystem on slippy $ sudo crossystem | grep -e recoverysw_cur -e wpsw_cur recoverysw_cur = (error) wpsw_cur = 1 Change-Id: I06dff09152bde30a3ffe58b1defe9d299155472c Signed-off-by: Duncan Laurie Reviewed-on: https://gerrit.chromium.org/gerrit/57471 Reviewed-by: Aaron Durbin Reviewed-on: http://review.coreboot.org/4221 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.
