Subject: [PATCH 0/3] platform/chrome: Only register PCHG if present

I see a printk when booting on chromebooks that don't have the
PCHG device. This series extracts the count function from the PCHG
driver and uses it in the mfd driver to skip registration of the PCHG
device if there aren't any charger ports. This gets rid of the message
at boot and removes one struct device from my system.

Stephen Boyd (3):
  platform/chrome: cros_ec_proto: Add peripheral charger count API
  mfd: cros_ec_dev: Only register PCHG device if present
  power: supply: PCHG: Use cros_ec_pchg_port_count()
