[PATCH v4 0/2] leds: leds-pca995x: Add support for NXP PCA9956B

[Pieterjan Camerlynck via B4 Relay]

This series adds support for NXP PCA9956B to the pca995x driver. This
chip is similar to the others but has 24 instead of 16 outputs and a
slightly different register layout. Datasheet available at [1].
