[PATCH v4] pinctrl: rockchip: add support for rk3568

[Peter Geis]

Good Afternoon,

I'm currently working on the rk3566 early bringup support in mainline
and encountered an issue with this patch set.
Unfortunately in the rk3568/rk3566 the gpio registers switched to the
(16 bits write enable / 16 bits config) register format that other
rockchip registers use.
This differs from previous chips where all 32 bits were used for gpio
configuration.
The patch fails to account for this, which causes all gpios to fail to function.

For clarity, this only affects GPIO_SWPORT_DR and GPIO_SWPORT_DDR.

I'm currently working on a patch to fix this issue, but I know that
you are planning on breaking out the gpio functions into a separate
driver and wanted to make you aware of this immediately.

Very Respectfully,
Peter Geis
