Tested on a TCAL6416, checked datasheets for the TCAL6408. They use the same programming model ad the NXP PCAL64xx, but support a lower supply power (1.08V to 3.6V) compared to PCAL (1.65V to 5.5V) Datasheet: https://www.ti.com/lit/ds/symlink/tcal6408.pdf Datasheet: https://www.ti.com/lit/ds/symlink/tcal6416.pdf Signed-off-by: Jan Remmet <j.remmet@phytec.de> Link: https://lore.kernel.org/r/20251216-wip-jremmet-tcal6416rtw-v2-3-6516d98a9836@phytec.de Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@oss.qualcomm.com> Signed-off-by: Sasha Levin <sashal@kernel.org> 2025-12-18T13:03:37+00:00 Arnd Bergmann arnd@arndb.de 2025-12-05T09:54:09+00:00 urn:sha1:f81f7e1344c43945c75129d740f434110b4f1f1e [ Upstream commit dd44d4d0c55a4ecf5eabf7856f96ed47e0684780 ] Selecting OF_GPIO is generally not allowed, it always gets enabled when both GPIOLIB and OF are turned on.

The generic GPIO API has been reworked and all users converted which allowed us to move the fields specific to the generic GPIO implementation out of the high-level struct gpio_chip into its own structure that wraps the gpio_chip. Other than that, there's nothing too exciting. Mostly minor tweaks and fixes all over the place, some refactoring and some small new features in helper modules. GPIO core: - add support for sparse pin ranges to the glue between GPIO and pinctrl - use a common prefix across all GPIO descriptor flags for improved namespacing New drivers: - add new GPIO driver for the Nuvoton NCT6694 - add new GPIO driver for MAX7360 Driver improvements: - add support for Tegra 256 to the gpio-tegra186 driver - add support for Loongson-2K0300 to the gpio-loongson-64bit driver - refactor the gpio-aggregator module to expose its GPIO forwarder API to other in-kernel users (to enable merging of a new pinctrl driver that uses it) - convert all remaining drivers to using the modernized generic GPIO chip API and remove the old interface - stop displaying global GPIO numbers in debugfs output of controller drivers - extend the gpio-regmap helper with a new config option and improve its support for GPIO interrupts - remove redundant fast_io parameter from regmap configs in GPIO drivers that already use MMIO regmaps which imply it - add support for a new model in gpio-mmio: ixp4xx expansion bus - order includes alphabetically in a few drivers for better readability - use generic device properties where applicable - use devm_mutex_init() where applicable - extend build coverage of drivers by enabling more to be compiled with COMPILE_TEST enabled - allow building gpio-stmpe as a module - use dev_err_probe() where it makes sense in drivers Late driver fixes: - fix setting GPIO direction to output in gpio-mpfs Documentation: - document the usage of software nodes with GPIO chips Device-tree bindings: - Add DT bindings documents for new hardware: Tegra256, MAX7360 - Document a new model in Loongson bindings: LS2K0300 - Document a new model using the generic GPIO binding: IXP4xx - Convert the DT binding for fsl,mxs-pinctrl to YAML -
