From
Subject[PATCH] platform/chrome: Update cros_ec_commands.h to latest ec commands
Date
Update from EC code base
https://chromium.googlesource.com/chromiumos/platform/ec/+/master/include/ec_commands.h
Formatted to match kernel syntax.

Add new commands:
EC_CMD_RAND_NUM : Request random numbers.
EC_CMD_RWSIG_INFO: Key information
EC_CMD_MKBP_WAKE_MASK: Define wake up mask for MKBP events.
EC_CMD_LOCATE_CHIP: For power delivery
EC_CMD_REBOOT_AP_ON_G3: For testing purposes
EC_CMD_GET_PD_PORT_CAPS: Get PD device information
EC_CMD_FP_READ_MATCH_SECRET: Used for Finger print sensor management.

Update commands:
EC_CMD_POWER_INFO (v0 was not used in the kernel)
EC_CMD_MOTION_SENSE_CMD (Add calibration mode, online calibration info).

Add new Mems sensors.
