Subject: [PATCH v2 0/3] gpio: bcm-kona: Various GPIO fixups
Date: Thu, 06 Feb 2025 18:45:59 +0100 [thread overview]
Message-ID: <20250206-kona-gpio-fixes-v2-0-409135eab780@gmail.com> (raw)
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).

Changes in v2:
- Made the unlock count code cleaner by using increment/decrement
operators (-- / ++)
- Added extra comment to relres function to match the one in reqres
- Link to v1: https://lore.kernel.org/r/20250130-kona-gpio-fixes-v1-0-dd61e0c0a9e7@gmail.com
