gpio/mpc83xx_spisel_boot.c: gpio driver for SPISEL_BOOT signal

2020-03-31T14:06:52Z

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.

dm: gpio: Allow control of GPIO uclass in SPL

2019-12-15T00:52:29Z

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). Signed-off-by: Simon Glass Reviewed-by: Bin Meng

gpio: sifive: add support for DM based gpio driver for FU540-SoC

2019-10-18T01:04:01Z

This patch adds a DM based driver model for gpio controller present in FU540-C000 SoC on HiFive Unleashed A00 board. This SoC has one GPIO bank and 16 GPIO lines in total, out of which GPIO0 to GPIO9 and GPIO15 are routed to the J1 header on the board. This implementation is ported from linux based gpio driver submitted for review by Wesley W. Terpstra and/or Atish Patra (many thanks !!).
