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"
