2019-12-03gpio: at91_gpio: Add bank namesJames Byrne
Make the at91_gpio driver set sensible GPIO bank names in the platform data. This makes the 'gpio status' command a lot more useful. Signed-off-by: James Byrne <james.byrne@origamienergy.com> Reviewed-by: Eugen Hristev <eugen.hristev@microchip.com>
2019-10-30gpio: da8xx_gpio: Fix the _gpio_direction_output functionKeerthy
_gpio_direction_output function currently calls gpio_set_value with the wrong gpio number. gpio_set_value in the uclass driver expects a different gpio number and the _gpio_direction_output is currently providing the number specific to the bank. Hence fix it by calling the _gpio_set_value function instead.

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 <wesley@sifive.com> and/or Atish Patra <atish.patra@wdc.com> (many thanks !!).

commit 1b898ffc040b ("gpio: dwapb_gpio: convert to livetree") introduced a bug in that dev->node of the gpio chip was accidentally set to the of_node of its bank subnode. What it meant to do was assign subdev->node, not dev->node. While this doesn't affect too many use cases, iterating over the gpio chip's properties doesn't work any more after that, so fix this.

The VCore III SoCs such as the Luton but also the Ocelot can remap an SPI flash directly in memory. However, for writing in the flash the communication has to be done by software. Each of the signal used for the SPI are exposed in a single register. In order to be able to use the soft-spi driver, the management of this pin is done through this simple gpio driver. Even if the main purpose of this driver is to be used by soft-spi, it can still be used as a normal gpio driver but with limitation: for example the first pin can't be used as output.

2018-11-29gpio: dwapb_gpio: fix binding without bank-name propertySimon Goldschmidt
As a preparation for merging the socfpga gen5 devicetree files from Linux, this patch makes the dwapb gpio driver work correctly without the 'bank-name' property on the gpio-controller nodes. This property is not present in the Linux drivers and thus is not present in the Linux devicetrees. It is only used to access pins via bank name. This fallback is necessary since without it, the driver will return an error code which will lead to an error in U-Boot startup. The bank names will still be added to the default board device trees in follow-up patch, but other boards using this driver and not including the bank name should also work with the socfpga.dtsi without adding the bank-name property.
