In the 7th generation of the SoC from Aspeed, the control logic of the GPIO controller has been updated to support per-pin control.

This driver adds support for the gpio features of the GPIO/PFC module in the Renesas RZ/G2L (R9A07G044) SoC. The new `rzg2l-pfc-gpio` driver is bound to the same device tree node as the `rzg2l-pfc-pinctrl` driver as the same hardware block provides both GPIO and pin multiplexing features.

Nomadik GPIO is a fairly simple GPIO module used in the ST-Ericsson Ux500 SoCs (and some older Nomadik SoCs). It uses registers where each GPIO is represented as a single bit, plus "set" and "clear" registers that allow updating the state without having to read the existing state.

2021-07-14gpio: Drop long unused DB8500 GPIO driverStephan Gerhold1-1/+0
The original U-Boot port for the ST-Ericsson U8500 SoC was dropped in commit 68282f55b846 ("arm: Remove unused ST-Ericsson u8500 arch"). Most of the drivers related to the old port were removed, but the db8500_gpio.c driver was forgotten for some reason. There is no way to select it and it does not compile anymore because of missing headers, so let's just remove it. The new port for U8500 introduced in commit 689088f9dae8 ("arm: Add support for ST-Ericsson U8500 SoC") fully embraces the new Driver Model and device trees where possible, so this is preparation to add a new, simplified GPIO driver based on DM_GPIO.

2020-03-31gpio/mpc83xx_spisel_boot.c: gpio driver for SPISEL_BOOT signalKlaus H. Sorensen1-0/+1
Some SoCs in the mpc83xx family, e.g. mpc8309, have a dedicated spi chip select, SPISEL_BOOT, that is used by the boot code to boot from flash. This chip select will typically be used to select a SPI boot flash. The SPISEL_BOOT signal is controlled by a single bit in the SPI_CS register. Implement a gpio driver for the spi chip select register. This allows a spi driver capable of using gpios as chip select, to bind a chip select to SPISEL_BOOT. It may be a little odd to do this as a GPIO driver, since the signal is neither GP or I, but it is quite convenient to present it to the spi driver that way. The alternative it to teach mpc8xxx_spi to handle the SPISEL_BOOT signal itself (that is how it's done in the linux kernel, see commit 69b921acae8a) Signed-off-by: Klaus H.

2019-12-15dm: gpio: Allow control of GPIO uclass in SPLSimon Glass1-1/+3
At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass is included in SPL/TPL without any control for boards. Some boards may want to disable this to reduce code size where GPIOs are not needed in SPL or TPL. Add a new Kconfig option to permit this. Default it to 'y' so that existing boards work correctly. Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to preserve the current behaviour. Also update the 74x164 GPIO driver since it cannot build with SPL. This allows us to remove the hacks in config_uncmd_spl.h and Makefile.uncmd_spl (eventually those files should be removed).
