spi: document tx/rx clock delay properties

2019-04-08T07:21:45+00:00

Tegra SPI controller has TX and RX trimmers to tuning the delay of SPI master clock with respect to the data. TX and RX tap values are based on the platform validation across the PVT and the trimmer values vary based on the trace lengths to the corresponding SPI devices.

spi: mt7621: Move SPI driver out of staging

2019-03-25T12:13:34+00:00

This patch moves the MT7621 SPI driver, which is used on some Ralink / MediaTek MT76xx MIPS SoC's, out of the staging directory. No changes to the source code are done in this patch. This driver version was tested successfully on an MT7688 based platform with an SPI NOR on CS0 and an SPI NAND on CS1 without any issues (so far). This patch also documents the devicetree bindings for the MT7621 SPI device driver.

Add documentation to the Synopsys SPI dt-bindings to support an optional interface clock that may be used for register access. Signed-off-by: Phil Edworthy Signed-off-by: Gareth Williams Signed-off-by: Mark Brown

dt-bindings: snps,dw-apb-ssi: Add mandatory clock bindings documentation

2019-03-20T17:20:43+00:00

The Synopsys SSI driver uses a mandatory clock that is not documented, so detail it in the device tree bindings. Also correct the spelling of "pins" in the "Optional Properties" section for the driver. Signed-off-by: Phil Edworthy Signed-off-by: Gareth Williams Signed-off-by: Mark Brown

spi: spi-fsl-spi: support use of the SPISEL_BOOT signal on MPC8309

2019-03-18T14:47:24+00:00

The MPC8309 has a dedicated signal, SPISEL_BOOT, usually used as chip select for the flash device from which the bootloader is loaded. It is not an ordinary gpio, but is simply controlled via the SPI_CS register in the system configuration. To allow accessing such a spi slave, we need to teach fsl_spi_cs_control() how to control the SPISEL_BOOT signal. To distinguish the gpio-controlled slaves, continue to have those use chip_select values of 0..ngpios-1, and use chip_select == ngpios for the boot flash. I'm not too happy with all the ifdeffery, but it seems to be necessary for guarding the sysdev/fsl_soc.h and use of get_immrbase() (spi-fsl-lib.c already contains similar ifdeffery). Googling suggests that the MPC8306 is similar, with the SPI_CS register at the same offset. Signed-off-by: Rasmus Villemoes Signed-off-by: Mark Brown
