Three fixes for issues I encountered, one of which is clearly world
ending if not resolved while the other two should go to stable because
they'll cause the wrong bank voltage setting to be applied or reported
in debugfs.
I discovered these myself while working on a new board that needed novel
pinctrl configuration. I think that few customers have probably been
impacted by incorrect bank voltage setting because it requires trying to
set a bank voltage that differs from what the FPGA configuration set, and
not only are the configurations currently in upstream and Microchip's
vendor devicetrees a match for the FPGA settings, I think customers are
using the FPGA configuration tool instead of pinctrl to configure IO
since that's how it has had to be done for the last several years.
pic64gx is where I spotted it since the config tool can't be used there,
so the impact is limited to users of that SoC that want to have non-default
bank voltages.
Cheers,
Conor.
