  pwm: pca9685: Drop explicit initialization of struct i2c_device_id::driver_data to 0 (2024-05-10 07:30:27 +0200)

pwm: Changes for v6.10-rc1

Apart for the normal updates for dt bindings, cleanups and support for
new device variants to existing drivers this completes the conversion to
pwmchip_alloc() which was started in the v6.9 development cycle.

Using pwmchip_alloc() is a precondition to the character device support
which allows easier and faster access to PWM devices. However there are
some issues I want to clean up before including it in mainline, so this
isn't contained here despite it was in next for some time.

Thanks to Alexandre Mergnat, Binbin Zhou, Dmitry Rokosov, George Stark,
Jerome Brunet and Varshini Rajendran for their contributions. Further
thanks go to AngeloGioacchino Del Regno, Conor Dooley, David Lechner,
Fabrice Gasnier, Florian Fainelli, Guenter Roeck, Gustavo A. R. Silva,
Krzysztof Kozlowski and Rob Herring for valuable patch review.

----------------------------------------------------------------

This is based on v6.9-rc5 because commit 141a8502214d ("pwm: bcm2835:
Drop open coded variant of devm_clk_rate_exclusive_get()") made the
build bots unhappy without commit 7f1dd39aedfc ("clk: Provide
!COMMON_CLK dummy for devm_clk_rate_exclusive_get()").

There are two commits touching drivers/hwmon. The driver modified here
provides a pwm device and it is converted to pwmchip_alloc() before
making pwmchip_alloc() mandatory. These two patches have Guenter's
blessing.

Please pull this for v6.10-rc1.

Thanks
Uwe
