This series makes two changes to v3:

  * Remove patches that are in LinusW linux-gpio for-next and fixes

  * Rename the 'pwm-offset' property to 'marvell,pwm-offset' as suggested by 
    Rob Herring

The original cover letter follows (with DT property name updated).

The gpio-mvebu driver supports the PWM functionality of the GPIO block for
earlier Armada variants like XP, 370 and 38x. This series extends support to
newer Armada variants that use CP11x and AP80x, like Armada 8K and 7K.

This series adds adds the 'marvell,pwm-offset' property to DT binding. 
'marvell,pwm-offset' points to the base of A/B counter registers that 
determine the PWM period and duty cycle.

The existing PWM DT binding reflects an arbitrary decision to allocate the A
counter to the first GPIO block, and B counter to the other one. In attempt to
provide better future flexibility, the new 'marvell,pwm-offset' property 
always points to the base address of both A/B counters. The driver code still 
allocates the counters in the same way, but this might change in the future 
with no change to the DT.

Tested AP806 and CP110 (both) on Armada 8040 based system.

Did you see the patches I sent during the last year doing this and
adding support for the fan on the GT-8k?

You refer to the series linked below, right?

  https://lore.kernel.org/linux-pwm/20200329104549.GX25745@shell.armlinux.org.uk/ (local)

(For some reason the LAKM archive is missing two years, including this
time frame)

I now remember that series. I even archived it locally. But then I
forgot about it, so I ended up recreating Armada 8K PWM support from
scratch. Sorry about that.

Any comment on this series?
