Re: [PATCH v3 0/3] pwm: axi-pwmgen: add external clock

Hello David,

When we created the driver for the AXI PWMGEN IP block, we overlooked
the fact that it can optionally be configured to use an external clock
in addition to the AXI bus clock. This is easy to miss in testing
because the bus clock is always on because it is driving other
peripherals as well.

Up to now, users were specifying the external clock if there was one and
the AXI bus clock otherwise. But the proper way to do this is to would
be to always specify the bus clock and only specify the external clock
if the IP block has been configured to use it.

To fix this, we add clock-names to the devicetree bindings and change
clocks to allow 1 or 2 clocks.

I applied path #1 for 6.17-rc1 and will send patches #2 and #3 to Linus
before 6.16.
