[PATCH v2 0/3] gpio: bcm-kona: Various GPIO fixups

From: Artur Weber
Date: Thu Feb 06 2025 - 12:46:21 EST


Fixes two issues that were preventing GPIO from working correctly:

- Lock/unlock functions tried to write the wrong bit to the unlock
registers for GPIOs with numbers larger than 32

- GPIOs only initialized as IRQs did not unlock the configuration
registers, causing IRQ-related configuration (e.g. setting the IRQ
type) to fail.

Also includes a minor fix to add a missing newline to an error message.

Tested on a Samsung Galaxy Grand Neo (baffinlite rev02) with a BCM23550
(DTS not yet in mainline).
