From: David Rivshin <redacted> This adds a binding description for the is31fl3236/35/18/16 I2C LED controllers. Signed-off-by: David Rivshin <redacted> --- Rob, I went with the 1-based 'reg' property here. I inferred that that would be your preference based on the previous thread [1]. Let me know if that's not the case. Changes from RFC: - Removed max-brightness property. - Added #address-cells and #size-cells properties to the example.
