gpio: Add driver for Nomadik GPIO

2021-07-14T20:47:56+00:00

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. The driver implements support for it for use together with DM_GPIO and the existing ste-dbx5x0.dtsi device tree. Cc: Linus Walleij Signed-off-by: Stephan Gerhold Reviewed-by: Linus Walleij

gpio: Drop long unused DB8500 GPIO driver

2021-07-14T20:47:55+00:00

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.

arm: Remove spear600 boards and the rest of SPEAr support

2021-07-08T02:22:42+00:00

These boards have not been converted to CONFIG_DM_USB by the deadline and is also missing conversion to CONFIG_DM. Remove them. As this is the last of the SPEAr platforms, so remove the rest of the remaining support as well. Cc: Vipin Kumar Signed-off-by: Tom Rini

gpio/mpc83xx_spisel_boot.c: gpio driver for SPISEL_BOOT signal

2020-03-31T14:06:52+00:00

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.
