Hi "Pali, I love your patch! Yet something to improve: [auto build test ERROR on linusw-pinctrl/devel] [also build test ERROR on linus/master v5.19 next-20220804] [If your patch is applied to the wrong git tree, kindly drop us a note.

Now when all MPP pins are properly defined and every MPP pin has GPIO function, always checks for errors in armada_37xx_gpio_request_enable() function when calling armada_37xx_pmx_set_by_name(). Function armada_37xx_pmx_set_by_name() should not return "not supported" error anymore for any GPIO pin when requesting GPIO mode.
