Hi Simon
The name given here for the patch as well as files "gpio-ext" is confusing for me.

As you stated here those are the IOs generated by CPLD on your board which can be programmed using bit-banging on two GPIOs.

So to me it those are "cpld_ios".

May you please rename these files accordingly and resend the patch series for better understanding?

To me "gpio-ext" is generic term application for "General purpose IOs"
