If anyone has any objections, please let me know. ------------------ From: Gabor Juhos commit 947c93eb29c2a581c0b0b6d5f21af3c2b7ff6d25 upstream. The controller has two consecutive OUTPUT_VAL registers and both holds output value for 32 GPIOs. Due to a missing adjustment, the current code always uses the first register while setting the output value whereas it should use the second one for GPIOs > 31. Add the missing armada_37xx_update_reg() call to adjust the register according to the 'offset' parameter of the function to fix the issue.
