[PATCH v2 0/7] leds: Support retaining state for the PCA955x

From: Eddie James
Date: Fri Jul 16 2021 - 18:03:47 EST


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, adds the
ability to query the hardware LED brightness, switches the I2C probe
function to probe_new, and uses more core functionality for parsing
the fwnode.
