The switch to the atomic API goes hand in hand with a few fixes to previously experienced issues: - The duty cycle is no longer lost after disable/enable (previously the OFF registers were cleared in disable and the user was required to call config to restore the duty cycle settings) - If one sets a period resulting in the same prescale register value, the sleep and write to the register is now skipped - Previously, only the full ON bit was toggled in GPIO mode (and full OFF cleared if set to high), which could result in both full OFF and full ON not being set and on=0, off=0, which is not allowed according to the datasheet - The OFF registers were reset to 0 in probe, which could lead to the forbidden on=0, off=0. Fixed by resetting to POR default (full OFF) Signed-off-by: Clemens Gruber <clemens.gruber@pqgruber.com> Acked-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
