pinctrl: aw9523: Make the driver tristate

2024-03-07T22:09:01Z

The AW9523 driver fails to build in some allmod configs since the I2C core can be a module, but AW9523 can not. Fix it up by allowing AW9523 to be a module (tristate).

pinctrl: Add driver for Awinic AW9523/B I2C GPIO Expander

2024-03-05T22:26:31Z

The Awinic AW9523(B) is a multi-function I2C gpio expander in a TQFN-24L package, featuring PWM (max 37mA per pin, or total max power 3.2Watts) for LED driving capability. It has two ports with 8 pins per port (for a total of 16 pins), configurable as either PWM with 1/256 stepping or GPIO input/output, 1.8V logic input; each GPIO can be configured as input or output independently from each other. This IC also has an internal interrupt controller, which is capable of generating an interrupt for each GPIO, depending on the configuration, and will raise an interrupt on the INTN pin to advertise this to an external interrupt controller.

pinctrl: Add support for the Lantic PEF2256 pinmux

2023-12-12T22:05:24Z

The Lantiq PEF2256 is a framer and line interface component designed to fulfill all required interfacing between an analog E1/T1/J1 line and the digital PCM system highway/H.100 bus. This kind of component can be found in old telecommunication system. It was used to digital transmission of many simultaneous telephone calls by time-division multiplexing. Also using HDLC protocol, WAN networks can be reached through the framer. This pinmux support handles the pin muxing part (pins RP(A..D) and pins XP(A..D)) of the PEF2256.

pinctrl: mlxbf3: remove broken Kconfig 'select'

2023-06-19T08:51:20Z

The new pinctrl driver selects GPIO_MLXBF3, but that can not be enabled yet because the MELLANOX_PLATFORM symbol does not exist in the tree: WARNING: unmet direct dependencies detected for GPIO_MLXBF3 Depends on [n]: GPIOLIB [=y] && PCI [=n] && (MELLANOX_PLATFORM [=n] && ARM64 [=y] || COMPILE_TEST [=y]) Selected by [y]: - PINCTRL_MLXBF3 [=y] && PINCTRL [=y] && (MELLANOX_PLATFORM [=n] && ARM64 [=y] || COMPILE_TEST [=y]) As it turns out, the pinctlr driver still builds fine without this, so just remove the select statement.
