Merge tag 'tag-chrome-platform-for-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/chrome-platform/linux
Pull chrome platform updates from Tzung-Bi Shih:
"cros_ec_proto:
- Fix protocol failure if EC firmware jumps to RO part
cros_typec_switch:
- Add USB Type-C switch driver for mode switches and retimers
- Integrate to EC for retimers, status update, and mode switches
- Clean-ups
cros_ec_typec:
- Clean-ups
- Use partner PDOs to register USB PD capabilities
chromeos_laptop:
- Fix a double-free
cros_ec_chardev:
- Check data length from userland to avoid a memory corruption
cros_ec:
- Expose suspend_timeout_ms in debugfs
- Notify the PM about wake events during resume"

The suspend_timeout_ms file controls the amount of + time in milliseconds the EC will wait before declaring a sleep + timeout event and attempting to wake the system. + + Supply 0 to use the default value coded into EC firmware. Supply + 65535 (EC_HOST_SLEEP_TIMEOUT_INFINITE) to disable the EC sleep + failure detection mechanism. Values in between 0 and 65535 + indicate the number of milliseconds the EC should wait after a + sleep transition before declaring a timeout. This includes both + the duration after a sleep command was received but before the + hardware line changed, as well as the duration between when the + hardware line changed and the kernel sent an EC resume command. + + Output will be in the format: "%u\n". |
