Subject: [PATCH 0/5] leds: Support retaining state for the PCA955x

This series implements the ability to retain the state of the LEDs
controlled by the PCA955x across system reboots. This includes a
change to the LED core driver to respect the retain-state-shutdown
device tree property. It also cleans up the PCA955x driver and adds
the ability to query the hardware LED brightness.

Eddie James (5):
  dt-bindings: leds: Add retain-state-shutdown boolean
  leds: leds-core: Implement the retain-state-shutdown property
  leds: pca955x: Clean up code formatting
  leds: pca955x: Add brightness_get function
  leds: pca955x: Implement the default-state property
