[PATCH v2 2/8] pinctrl: sunxi: increase number of GPIO bank regulators
Posted by Andre Przywara 10 months, 1 week ago
By design, the Allwinner pinctrl IP always supported up to 11 GPIO banks,
though no SoC ever used more than 9 banks so far.
The Allwinner A523 has pins in all 11 banks, which exceeds the number of
per-bank regulators that we currently support, as this was set to 9.

Increase the size of the array to hold up to 11 regulator structs, to
support pins in bank J and K as well.
