2021-01-29spi: mtk_snor: add support for MTK SPI NOR controllerSkyLake.Huang
This patch adds support for MTK SPI NOR controller, which you can see on mt7622 & mt7629. 1. This controller is designed only for SPI NOR. We can't adjust its bus clock dynamically. Set clock in dts instead. 2. This controller only supports 1-1-1 write mode. 3. Remove mtk_snor_match_read() since upper SPI-MEM layer already handles command. 4. sf read/write/update commands are tested with this driver. Signed-off-by: SkyLake.Huang <skylake.huang@mediatek.com>
2021-01-24spi: add spi controller support for MediaTek MT7620 SoCWeijie Gao
This patch adds spi controller support for MediaTek MT7620 SoC. The SPI controller supports two chip selects. These two chip selects are implemented as two separate register groups, but they share the same bus (DI/DO/CLK), only CS pins are dedicated for each register group. Appearently these two register groups cannot operates simulataneously so they are implemented as one controller.

2020-07-16spi: fsl_qspi: Support to use full AHB space on i.MXYe Li
i.MX platforms provide large AHB mapped space for QSPI, each controller has 256MB. However, current driver only maps small size (AHB buffer size) of AHB space, this implementation causes i.MX failed to boot M4 with QSPI XIP image. Add config CONFIG_FSL_QSPI_AHB_FULL_MAP (default enabled for i.MX) to address above problem. When the config is set: 1. Full AHB space is divided to each CS. 2. A dedicated LUT entry is used for AHB read only. 3. The MODE instruction in LUT is replaced to standard ADDR instruction 4. The address in spi_mem_op is used to SFAR and AHB read Signed-off-by: Ye Li <ye.li@nxp.com> Reviewed-by: Ashish Kumar <Ashish.Kumar@nxp.com> Reviewed-by: Kuldeep Singh <kuldeep.singh@nxp.com>

2020-01-27spi: nxp_fspi: new driver for the FlexSPI controllerMichael Walle
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).
