From ae0fb762a2b0592a9734120bd14e0b7a98af9d31 Mon Sep 17 00:00:00 2001 From: Joel Kitching Date: Sun, 7 Apr 2019 00:37:14 +0800 Subject: chromeos: clean up "recovery" and "write protect" GPIOs The "write protect" GPIO's cached value is never actually read after entering depthcharge. Ensure the value from get_write_protect_state() is being transferred accurately, so that we may read this GPIO value in depthcharge without resampling. The cached value of the "recovery" GPIO is read only on certain boards which have a physical recovery switch. Correct some of the values sent to boards which presumably never read the previously incorrect value. Most of these inaccuracies are from non-inverted values on ACTIVE_LOW GPIOs.
