2017-02-14spi: lantiq-ssc: add support for Lantiq SSC SPI controllerHauke Mehrtens1-0/+29
This driver supports the Lantiq SSC SPI controller in master mode. This controller is found on Intel (former Lantiq) SoCs like the Danube, Falcon, xRX200, xRX300. The hardware uses two hardware FIFOs one for received and one for transferred bytes. When the driver writes data into the transmit FIFO the complete word is taken from the FIFO into a shift register. The data from this shift register is then written to the wire. This driver uses the interrupts signaling the status of the FIFOs and not the shift register. It is also possible to use the interrupts for the shift register, but they will send a signal after every word. When using the interrupts for the shift register we get a signal when the last word is written into the shift register and not when it is written to the wire. After all FIFOs are empty the driver busy waits till the hardware is not busy any more and returns the transfer status.

2016-12-14spi: sh-msiof: Add R-Car Gen 2 and 3 fallback bindingsSimon Horman1-6/+13
In the case of Renesas R-Car hardware we know that there are generations of SoCs, e.g. Gen 2 and Gen 3. But beyond that it's not clear what the relationship between IP blocks might be. For example, I believe that r8a7790 is older than r8a7791 but that doesn't imply that the latter is a descendant of the former or vice versa. We can, however, by examining the documentation and behaviour of the hardware at run-time observe that the current driver implementation appears to be compatible with the IP blocks on SoCs within a given generation. For the above reasons and convenience when enabling new SoCs a per-generation fallback compatibility string scheme is being adopted for drivers for Renesas SoCs. Also: * Deprecate renesas,sh-msiof. It seems poorly named as it is only compatible with SH-Mobile. It also appears unused in mainline.

One of those is the 3-clocks controller management where the spi is fed with three clocks: "spi", "busclkN" and "ioclk".

2016-05-30spi: orion: Add direct access modeStefan Roese1-1/+48
This patch adds support for the direct access mode to the Orion SPI driver which is used on the Marvell Armada based SoCs. In this direct mode, all data written to (or read from) a specifically mapped MBus window (linked to one SPI chip-select on one of the SPI controllers) will be transferred directly to the SPI bus. Without the need to control the SPI registers in between. This can improve the SPI transfer rate in such cases. Both, direct-read and -write mode are supported. But only the write mode has been tested. This mode especially benefits from the SPI direct mode, as the data bytes are written head-to-head to the SPI bus, without any additional addresses. One use-case for this direct write mode is, programming a FPGA bitstream image into the FPGA connected to the SPI bus at maximum speed. This mode is described in chapter "22.5.2 Direct Write to SPI" in the Marvell Armada XP Functional Spec Datasheet.

Two other SoCs got added that are updated versions of existing SoC families, so the port mainly consists of new dts files: - The Hisilicon Hip06/D03 is the latest server platform from Huawei/Hisilicon, and follows the Hip05/D02 platform. - Rockchip RK3399 follows the 32-bit RK3288 that is popular in low-end Chromebooks and the 64-bit RK3368 that is mainly found in chinese Android TV boxes.

Pull ARM DT updates from Olof Johansson: "As usual, the bulk of this release is again DT file contents. There's a huge number of changes here, and it's challenging to give a crisp overview of just what is in here. To start with: New boards: - TI-based DM3730 from LogicPD (Torpedo) - Cosmic+ M4 (nommu) initial support (Freescale Vybrid) - Raspberry Pi 2 DT files - Watchdog on Meson8b - Veyron-mickey (ASUS Chromebit) DTS - Rockchip rk3228 SoC and eval board - Sigma Designs Tango4 Improvements: - Improved support for Qualcomm APQ8084, including Sony Xperia Z DT files - Misc new devices for Rockchip rk3036 and rk3288 - Allwinner updates for misc SoCs and systems ... and a _large_ number of other changes across the field. Devices added to SoC DTSI and board DTS files for a number of SoC vendors, new product boards on already-supported SoCs, cleanups and refactorings of existing DTS/DTSI files and a bunch of other changes" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (469 commits) ARM: dts: compulab: add new board description ARM: versatile: add the syscon LEDs to the DT dts: vt8500: Fix errors in SDHC node for WM8505 ARM: dts: imx6q: clean up unused ipu2grp ARM: dts: silk: Add compatible property to "partitions" node ARM: dts: gose: Add compatible property to "partitions" node ARM: dts: porter: Add compatible property to "partitions" node ARM: dts: koelsch: Add compatible property to "partitions" node ARM: dts: lager: Add compatible property to "partitions" node ARM: dts: bockw: Add compatible property to "partitions" node ARM: dts: meson8b: Add watchdog node Documentation: watchdog: Add new bindings for meson8b ARM: meson: Add status LED for Odroid-C1 ARM: dts: uniphier: fix a typo in comment block ARM: bcm2835: Add the auxiliary clocks to the device tree.
