2025-05-15gpio: TODO: add item about GPIO drivers reading struct gpio_chip::baseAhmad Fatoum
drivers/pinctrl/pinctrl-at91.c uses struct gpio_chip::base to find out which bit to set in a register: dev_dbg(npct->dev, "enable pin %u as GPIO\n", offset); mask = 1 << (offset - chip->base); This adds a non-obvious dependency on the global numberspace from the GPIO driver itself, even if all consumers use the descriptor API. More such instances may exist and will need to be fixed in the quest for removal of the global numberspace, so add a reminder about it to the TODO list.

2025-05-15gpio: mxc: configure dynamic GPIO base for CONFIG_GPIO_SYSFS=nAhmad Fatoum
i.MX GPIO numbering has been deterministic since commit 7e6086d9e54a ("gpio/mxc: specify gpio base for device tree probe"), a year after device tree support was first added back in 2011. Reverting to dynamically allocated GPIO base now would break most systems making use of the sysfs API. These systems will be eventually broken by the removal of the sysfs API, but that would result in GPIO scripts not working instead of essentially toggling at random according to probe order, which would happen if we unconditionally set base to -1. Yet, the warning is annoying and has resulted in many rejected attempts to remove it over the years[1][2][3]. As the i.MX GPIO driver is device tree only, GPIO_SYSFS is the only consumer of the deterministic GPIO numbering. Let's therefore restrict the static base and the warning that comes with it to configurations with CONFIG_GPIO_SYSFS enabled.

2025-05-09nvmem: max77759: Add Maxim MAX77759 NVMEM driverAndré Draszik
The Maxim MAX77759 is a companion PMIC for USB Type-C applications and includes Battery Charger, Fuel Gauge, temperature sensors, USB Type-C Port Controller (TCPC), NVMEM, and a GPIO expander. This driver exposes the non volatile memory using the platform device registered by the core MFD driver.

2025-05-09mfd: max77759: Add Maxim MAX77759 core driverAndré Draszik
The Maxim MAX77759 is a companion PMIC for USB Type-C applications and includes Battery Charger, Fuel Gauge, temperature sensors, USB Type-C Port Controller (TCPC), NVMEM, and a GPIO expander. Fuel Gauge and TCPC have separate and independent I2C addresses, register maps, and interrupt lines and are therefore excluded from the MFD core device driver here. The GPIO and NVMEM interfaces are accessed via specific commands to the built-in microprocessor. This driver implements an API that client drivers can use for accessing those.
