Subject: [PATCH v2 0/2] leds: pca955x: Add HW blink support

This series adds support for blinking using the PCA955x chip, falling
back to software blinking if another LED on the chip is already blinking
at a different rate, or if the requested rate isn't representable with
the PCA955x.

Changes since v1:
 - Rework the blink function to fallback to software blinking if the
   period is out of range of the chip's capabilities or if another LED
   on the chip is already blinking at a different rate.
 - Add the cleanup patch
