With this patch, an issue is observed on am62a:

root@...2axx-evm:~# dmesg | grep tps
..
[   12.122631] tps6594-pinctrl tps6594-pinctrl.2.auto: error -EINVAL: Couldn't register gpio_regmap 
driver
[   12.133216] tps6594-pinctrl: probe of tps6594-pinctrl.2.auto failed with error -22

Without this patch, the issue disappears. Do you observe
the same result with your am62p ?
