Hey Maurice!

 MK>   $ zgrep PCA953 /proc/config.gz
 MK>   CONFIG_GPIO_PCA953X=m
 MK>   # CONFIG_GPIO_PCA953X_IRQ is not set
 MK>   CONFIG_LEDS_PCA9532=m
 MK>   # CONFIG_LEDS_PCA9532_GPIO is not set

Errrr ... only CONFIG_GPIO_PCA953X_IRQ and CONFIG_LEDS_PCA9532_GPIO are not enabled.  The chipset itself is modular along with CONFIG_LEDS_PCA9532.

Getting old buddy.  Mind you we got uefi boots working ... again.  Not sure that is anything worth bragging about since we'd still be using legacy boots if that had been an option.  :-/

Life is good,
Maurice
