spi: nxp_fspi: new driver for the FlexSPI controller

2020-01-27T16:57:21Z

This is a port of the kernel's spi-nxp-fspi driver. It uses the new spi-mem interface and does not expose the more generic spi-xfer interface. The source was taken from the v5.3-rc3 tag. The port was straightforward: - remove the interrupt handling and the completion by busy polling the controller - remove locks - move the setup of the memory windows into claim_bus() - move the setup of the speed into set_speed() - port the device tree bindings from the original fspi_probe() to ofdata_to_platdata() There were only some style change fixes, no change in any logic. For example, there are busy loops where the return code is not handled correctly, eg. only prints a warning with WARN_ON(). This port intentionally left most functions unchanged to ease future bugfixes. This was tested on a custom LS1028A board. Because the LS1028A doesn't have proper clock framework support, changing the clock speed was not tested. This also means that it is not possible to change the SPI speed on LS1028A for now (neither is it possible in the linux driver).

spi: Drop obsolete mtk_qspi driver references

2019-07-25T13:22:20Z

Since u-boot has added the spi-mem framework and replaced the spi-nor framework, the mtk_qspi is no longer compatible with the new spi-nor driver. Remove this driver along with replacing config item with new mtk spi-nor driver.

spi: Add SiFive SPI driver

2019-07-18T11:41:16Z

This patch adds SiFive SPI driver. The driver is 100% DM driver and it determines input clock using clk framework. The SiFive SPI block is found on SiFive FU540 SOC and is used to access flash and MMC devices on SiFive Unleashed board. This driver implementation is inspired from the Linux SiFive SPI driver available in Linux-5.2 or higher and SiFive FSBL sources.
