[PATCH 0/3] gpio: tps65219: Fix TPS6521x GPIO handling

[Karl Mehltretter]

I found patch 1 while looking through the tree for code that mixes up
bit numbers and bit masks. Patches 2 and 3 turned up while checking the
nearby TPS65214 code.

Patch 1 fixes TPS65219 input reads. Patches 2 and 3 fix TPS65214
direction handling.

I tested the series under x86_64 QEMU 10.2.1 with a temporary KUnit
suite and a RAM-backed regmap. Both tests failed on the base commit.
The TPS65219 input-high test returned low, and the TPS65214
direction-output test left GPIO_CONFIG clear. Both tests pass with this
series. A W=1 build of drivers/gpio/gpio-tps65219.o also passes.

The KUnit suite is not included. It tests the driver logic, not real
PMIC hardware. I have not tested this on real hardware. Testing on
affected hardware is welcome.
