The first patch was originally part of the series adding Armada 8K/7K pwm support. I split it out to a separate series following review comments from Uwe Kleine-König who spotted a few more issues. There is no dependency between this and the Armada 8K/7K series. Baruch Siach (5): gpio: mvebu: fix pwm get_state period calculation gpio: mvebu: improve pwm period calculation accuracy gpio: mvebu: make pwm apply/get_state closer to idempotent gpio: mvebu: don't limit pwm period/duty_cycle to UINT_MAX gpio: mvebu: document zero pwm duty cycle limitation drivers/gpio/gpio-mvebu.c | 34 ++++++++++++++-------------------- 1 file changed, 14 insertions(+), 20 deletions(-)
