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 !!). The linux driver can be referred here [1] [1]: https://lkml.org/lkml/2018/10/9/1103 Signed-off-by: Sagar Shrikant Kadam Reviewed-by: Bin Meng

gpio: stm32: Rename stm32f7_gpio to stm32_gpio

As this driver is used on stm32f4/f7/h7 and stm32mp1 SoCs, rename it with a more generic name. Signed-off-by: Patrice Chotard Reviewed-by: Patrick Delaunay

mips: mscc_sgpio: Add the MSCC serial GPIO device (SIO)

2019-01-16T12:56:43Z

This add support for the the MSCC serial GPIO driver in MSCC VCoreIII-based SOCs. By using a serial interface, the SIO controller significantly extends the number of available GPIOs with a minimum number of additional pins on the device. The primary purpose of the SIO controller is to connect control signals from SFP modules and to act as an LED controller. This adds the base driver. Signed-off-by: Lars Povlsen

gpio: mscc-bitbang-spi: Add a simple gpio driver for bitbgang spi

2018-12-19T14:23:01Z

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.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini
