[RFC PATCH 0/4] ESWIN EIC7700 pinctrl driver
From: Emil Renner Berthing

Hi Pinkesh et. al
It's great to see you've begun upstreaming support for the EIC7700. I
read some of the data sheet for the SoC and noticed the pinctrl is quite
simple and could benefit from using the same model as the TH1520 pinctrl
driver. This version should do the same as the vendor driver, but in
less than 2/3 the code.
I hope you'll consider switching to this version once the basic
support[1] lands. This patchset also depends on that series.
