Unfortunately I don't have the HW to test it so marking the patches that introduce functional change as RFT and Cc'ing the original author. v1 -> v2: - add new regmap helper: regmap_assign_bits() - fix lvl vs sel register access - set value in direction_output callback v2 -> v3: - drop the regmap helper from series Note: I didn't use the fancy method of offset calculation Andy and David suggested because this series broke the driver according to Jan - let's get it right before we modify it any more. I found a couple problems that could maybe cause the crash. Jan: could you give it another spin?
