gpio: GPIO_MVEBU should not default to y when compile-testing

2024-12-04T14:27:49+00:00

Merely enabling compile-testing should not enable additional
functionality.

Fixes: 956ee0c5c969c9ca ("gpio: mvebu: allow building the module with COMPILE_TEST=y")

gpio: tegra186: Allow to enable driver on Tegra234

2024-11-18T10:45:06+00:00

Support for Tegra234 was added to the tegra186 driver in 1db9b241bb56 (
"gpio: tegra186: Add support for Tegra234"). But the driver is not
selectable on Tegra234. Update the Kconfig entry to allow the driver to be
enabled on Tegra234.

Enable the driver by default on Tegra 234 as well, similar to the other
platforms it supports.

gpio: mpfs: add polarfire soc gpio support

2024-11-06T13:40:08+00:00

Add a driver to support the Polarfire SoC gpio controller. Interrupt
controller support is unavailable for now and will be added at a later
date.

gpio: grgpio: drop Kconfig dependency on OF_GPIO

2024-10-22T07:03:59+00:00

This driver has no build-time dependency on gpiolib-of so remove the
Kconfig switch.

gpio: fold the Kconfig prompt into the option type for GPIO CDEV

2024-10-17T06:53:19+00:00

The 'if !EXPERT' bit will work fine if it follows the 'bool "foobar"'
declaration. No need to have separate entries for it.

gpio: davinci: allow building the module with COMPILE_TEST=y

2024-10-14T08:28:39+00:00

Make it possible to build the module when COMPILE_TEST is enabled for
better build coverage. Stop using of_match_ptr() to avoid build warnings.

gpio: mvebu: drop dependency on OF_GPIO

2024-10-14T08:28:01+00:00

This driver doesn't really depend on interfaces from OF_GPIO so the
Kconfig dependency can be dropped.

gpio: add support for FTDI's MPSSE as GPIO

2024-10-14T07:07:32+00:00

FTDI FT2232H is a USB to GPIO chip. Sealevel produces some devices
with this chip. FT2232H presents itself as a composite device with two
interfaces (each is an "MPSSE"). Each MPSSE has two banks (high and low)
of 8 GPIO each. I believe some MPSSE's have only one bank, but I don't
know how to identify them (I don't have any for testing) and as a result
are unsupported for the time being.

Additionally, this driver provides software polling-based interrupts for
edge detection. For the Sealevel device I have to test with, this works
well because there is hardware debouncing. From talking to Sealevel's
people, this is their preferred way to do edge detection.
