Merge tag 'chrome-platform-v6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/chrome-platform/linux
Pull chrome platform updates from Tzung-Bi Shih:
"New:
- Support new EC if the memory region information comes from the CRS
ACPI resource descriptor in cros_ec_lpc
Improvements:
- Make sure EC is in RW before probing
- Only check events on MKBP notifies to reduce the number of query
commands in cros_ec_lpc
Cleanups:
- Remove unused code and DT bindings for cros-kbd-led-backlight
- Constify 'struct bin_attribute' in cros_ec_vbc
- Use str_enabled_disabled() in cros_usbpd_logger"
