2021-07-20pwm: imx1: Don't disable clocks at device remove timeUwe Kleine-König1-2/+0
[ Upstream commit 1bc6ea31cb41d50302a3c9b401964cf0a88d41f9 ] The .remove() callback disables clocks that were not enabled in .probe(). So just probing and then unbinding the driver results in a clk enable imbalance. So just drop the call to disable the clocks. (Which BTW was also in the wrong order because the call makes the PWM unfunctional and so should have come only after pwmchip_remove()).

2021-03-22pwm: Always allocate PWM chip base ID dynamicallyUwe Kleine-König1-1/+0
Since commit 5e5da1e9fbee ("pwm: ab8500: Explicitly allocate pwm chip base dynamically") all drivers use dynamic ID allocation explicitly. New drivers are supposed to do the same, so remove support for driver specified base IDs and drop all assignments in the low-level drivers.

2020-12-17pwm: imx1: Use dev_err_probe() to simplify error handlingAnson Huang1-15/+6
dev_err_probe() can reduce code size, uniform error handling and record the defer probe reason etc., use it to simplify the code.

2019-01-16pwm: imx: Split into two driversUwe Kleine-König1-0/+199
The two PWM implementations called v1 (for i.MX1 and i.MX21) and v2 (for i.MX27 and later) have nothing in common apart from needing two clocks named "per" and "ipg" and being integrated in a SoC named i.MX. So split the file containing the two disjunct drivers into two files and two complete separate drivers.
