Subject: [PATCH 0/2] Add sysfs attributes to cros-ec-typec

This patch series adds sysfs attributes to expose the state of EC.
These attributes provide user-space applications with a read-only view of
the EC state, eliminating the need for ioct calls and facilitating
diagnostics.

Tested on a ChromeOS Brya device with kernel 6.6. Verified that user-space
applications can correctly read the new sysfs attributes.

Andrei Kuchynski (2):
  platform/chrome: cros_ec_typec: Expose PD mux status via sysfs
  platform/chrome: cros_ec_typec: Expose AP_MODE_ENTRY feature state via
    sysfs
