2020-05-29spi: Convert DW SPI binding to DT schemaSerge Semin3-73/+133
Modern device tree bindings are supposed to be created as YAML-files in accordance with dt-schema. This commit replaces two DW SPI legacy bare text bindings with YAML file. As before the bindings file states that the corresponding dts node is supposed to be compatible either with generic DW APB SSI controller or with Microsemi/Amazon/Renesas/Intel vendors-specific controllers, to have registers, interrupts and clocks properties. Though in case of Microsemi version of the controller there must be two registers resources specified. Properties like clock-names, reg-io-width, cs-gpio, num-cs, DMA and slave device sub-nodes are optional.

2020-05-14dt-bindings: Fix incorrect 'reg' property sizesRob Herring2-2/+2
The examples template is a 'simple-bus' with a size of 1 cell for had between 2 and 4 cells which really only errors on I2C or SPI type devices with a single cell. The easiest fix in most cases is to change the 'reg' property to for 1 cell address and size. In some cases with child devices having 2 cells, that doesn't make sense so a bus node is needed.

2020-05-03dt-bindings: Remove cases of 'allOf' containing a '$ref'Rob Herring4-70/+55
json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Scripted with ruamel.yaml with some manual fixups. Some minor whitespace changes from the script.

The descriptions for the spi-rx-bus-width and spi-tx-bus-width properties refer to "MISO" and "MOSI", which are not explained in the document. While these abbreviations are fairly common when talking about SPI, and thus may not need an explanation, they are not entirely correct in this context, as the SPI controller may be used in slave mode instead of master mode.

spi-mtk-nor is a driver to replace mtk-quadspi and they have almost the same device-tree bindings. Reuse this binding documentation and convert it for new driver: 1. "Mediatek SoCs" -> "Mediatek ARM SoCs" because MTK MIPS SoCs use different controllers. 2. document "interrupts" as a required property because it's available on all SoCs with this controller and new driver takes advantages of it. It's implemented as optional only to maintain backward compatibility. 3. add a dummy interrupt binding in example.

2020-03-05dt-bindings: spi: convert rockchip spi bindings to yamlJohan Jonker2-58/+105
Current dts files with 'spi' nodes are manually verified. In order to automate this process spi-rockchip.txt has to be converted to yaml. In the new setup spi-rockchip.yaml will inherit properties from spi-controller.yaml. Add document to MAINTAINERS. Also rk3188.dtsi, rk3288.dtsi, rk3368.dtsi and rk3399.dtsi use an extra fallback string, so change this in the documentation. Changed: "rockchip,rk3188-spi", "rockchip,rk3066-spi" "rockchip,rk3288-spi", "rockchip,rk3066-spi" "rockchip,rk3368-spi", "rockchip,rk3066-spi" "rockchip,rk3399-spi", "rockchip,rk3066-spi" Signed-off-by: Johan Jonker <jbx6244@gmail.com> Link: https://lore.kernel.org/r/20200304184203.9548-1-jbx6244@gmail.com Signed-off-by: Mark Brown <broonie@kernel.org>

Vladimir Oltean <olteanv@gmail.com>: This series makes room in the driver for differentiation between the controllers which currently operate in TCFQ mode. Most of these are actually capable of a lot more in terms of throughput. This is in preparation of a second series which will convert the remaining users of TCFQ mode altogether to XSPI mode with command cycling.

2020-03-04spi: spi-fsl-dspi: Add specific compatibles for all Layerscape SoCsVladimir Oltean1-6/+11
Make the second compatible string optional for LS1012A, LS1088A and LS2080A. Old versions of the spi-fsl-dspi.c driver still need to probe on the old, generic compatible string for these controllers (such as "fsl,ls1021a-v1.0-dspi") which provides less functionality. Document the device tree bindings for LS1043A and LS1046A, whose bindings are already in use in fsl-ls1043a.dtsi and fsl-ls1046a.dtsi. Introduce new compatible strings for LS1028A and LX2160A. There will be no second compatible string for these.

Summary: - Implement user_access_begin() and friends for our platforms that support controlling kernel access to userspace. - Enable CONFIG_VMAP_STACK on 32-bit Book3S and 8xx. - Some tweaks to our pseries IOMMU code to allow SVMs ("secure" virtual machines) to use the IOMMU. - Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE to the 32-bit VDSO, and some other improvements. - A series to use the PCI hotplug framework to control opencapi card's so that they can be reset and re-read after flashing a new FPGA image.
