e8bf17d5 - platform/chrome: cros_ec: Expose suspend_timeout_ms in debugfs

platform/chrome: cros_ec: Expose suspend_timeout_ms in debugfsIn modern Chromebooks, the embedded controller has a mechanism whereit will watch a hardware-controlled line that toggles in suspend, andwake the system up if an expected sleep transition didn't occur. Thiscan be very useful for detecting power management issues where thesystem appears to suspend, but doesn't actually reach its lowestexpected power states.Sometimes it's useful in debug and test scenarios to be able to controlthe duration of that timeout, or even disable the EC timeout mechanismaltogether. Add a debugfs control to set the timeout to values otherthan the EC-defined default, for more convenient debug anddevelopment iteration.Signed-off-by: Evan Green Reviewed-by: Prashant Malani Reviewed-by: Stephen Boyd Reviewed-by: Guenter Roeck Link: https://lore.kernel.org/r/20220822144026.v3.1.Idd188ff3f9caddebc17ac357a13005f93333c21f@changeid[tzungbi: fix one nit in Documentation/ABI/testing/debugfs-cros-ec.]Signed-off-by: Tzung-Bi Shih List of files: /linux-6.15/Documentation/ABI/testing/debugfs-cros-ec

mfd / platform: cros_ec_debugfs: Expose resume result via debugfsFor ECs that support it, the EC returns the number of slp_s0transitions and whether or not there was a timeout in the resumeresponse. Expose the last resume result to usermode via debugfs sothat usermode can detect and report S0ix timeouts.Signed-off-by: Evan Green Acked-by: Lee Jones Signed-off-by: Enric Balletbo i Serra List of files: /linux-6.15/Documentation/ABI/testing/debugfs-cros-ec
