The ptn3460 driver recently started usign the gpiod interface which is only available on platforms that come with GPIOLIB support, resulting in a compile-time error:

Similarly, the newly added ps8622 driver started out with the same problem.
This patch adds explicit Kconfig dependencies to avoid trying to build invalid configurations.

Applied, thanks.
