2019-07-30MIPS: qi_lb60: Migrate to devicetreePaul Cercueil3-496/+287
Move all the platform data to devicetree. The only bit dropped is the PWM beeper, which requires the PWM driver to be updated. I figured it's okay to remove it here since it's really a non-critical device, and it'll be re-introduced soon enough. The other change is the CS line of the SPI is now set as active low. The SPI core would have forced "active low" anyway, unless the 'spi-cs-high' property is set. In the process of moving to devicetree, we also switched to new drivers: - We use the simple-audio-card and simple-amplifier drivers instead of the custom ASoC code; - We use the new Ingenic DRM driver coupled with the GiantPlus GPM940B0 DRM panel driver instead of the old framebuffer driver; - We use the new jz4780-dma driver instead of the old jz4740-dma one; - We use the ingenic-nand and jz4740-ecc drivers instead of the old jz4740-nand driver; - We use ingenic-battery instead of jz4740-battery; - We use iio-hwmon instead of jz4740-hwmon; - We use ingenic-iio instead of the old jz4740-adc MFD driver.

2019-07-25MIPS: BCM47XX: Add support for Netgear R6200 V1Edward Matijević3-0/+12
The Netgear R6200 v1 uses a BCM4718A1 SOC and a BCM4352/BCM4360 for 5GHz wireless. This patch adds support for detecting this model board and registers the 3 buttons. I have tested that the device can boot kernels 4.14 and 4.19 under OpenWRT. There is one issue that the LEDs on the device are controlled by a 74HC164 that uses bit-banging instead of SPI so it isn't accessible to the kernel without adding a workaround. Without any workaround the device on boot will flash all LEDs once then the power LED will remain amber as all other LEDs stay off.

2019-07-21MIPS: Undefine PMD_ORDER for 32-bit buildsDaniel Silsby1-1/+1
During an update long ago to conform to 4-level page code, PMD_ORDER was changed from 0 to 1, despite the fact that a PMD table is not used at all in a 32-bit MIPS build. PMD_ORDER does not seem to be used in these builds. Now, it matches PUD_ORDER, a nonsense #define to give a build failure with informative error. The older commit that had redefined PMD_ORDER was commit c6e8b587718c ("Update MIPS to use the 4-level pagetable code thereby getting rid of the compacrapability headers.")

2019-07-21MIPS: Add partial 32-bit huge page supportDaniel Silsby3-7/+73
This adds initial support for huge pages to 32-bit MIPS systems. Systems with extended addressing enabled (EVA,XPA,Alchemy/Netlogic) are not yet supported. With huge pages enabled, this implementation will increase page table memory overhead to match that of a 64-bit MIPS system.

2019-07-21MIPS: Disallow CPU_SUPPORTS_HUGEPAGES for XPA,EVADaniel Silsby1-0/+1
In preparation for 32-bit MIPS huge page support. EVA,XPA are extended-addressing modes for 32-bit MIPS systems. Because huge pages aren't currently supported in 32-bit MIPS, this doesn't take any features away from EVA,XPA-enabled systems. However, the soon-to- come 32-bit MIPS huge page support doesn't yet support them. This also disables CPU_SUPPORTS_HUGEPAGES for the small number of 32-bit MIPS CPUs from Alchemy/Netlogic that support a custom 36-bit extended addressing. It's unknown if they even support huge pages in hardware.

Now that examples are validated against the DT schema, an error with required 'clocks' property missing is exposed: Documentation/devicetree/bindings/pinctrl/st,stm32-pinctrl.example.dt.yaml: \ pinctrl@40020000: gpio@0: 'clocks' is a required property Documentation/devicetree/bindings/pinctrl/st,stm32-pinctrl.example.dt.yaml: \ pinctrl@50020000: gpio@1000: 'clocks' is a required property Documentation/devicetree/bindings/pinctrl/st,stm32-pinctrl.example.dt.yaml: \ pinctrl@50020000: gpio@2000: 'clocks' is a required property Add the missing 'clocks' properties to the examples to fix the errors.

2019-07-20dt-bindings: iio: ad7124: Fix dtc warnings in exampleRob Herring1-33/+38
With the conversion to DT schema, the examples are now compiled with dtc. The ad7124 binding example has the following warning: Documentation/devicetree/bindings/iio/adc/adi,ad7124.example.dts:19.11-21: \ Warning (reg_format): /example-0/adc@0:reg: property has invalid length (4 bytes) (#address-cells == 1, #size-cells == 1) There's a default #size-cells and #address-cells values of 1 for examples. For examples needing different values such as this one on a SPI bus, they need to provide a SPI bus parent node. Fixes: 26ae15e62d3c ("Convert AD7124 bindings documentation to YAML format.")

The schema examples are now validated against the schema itself.

The Aspeed pinctl schema have errors in the 'compatible' schema: Documentation/devicetree/bindings/pinctrl/aspeed,ast2400-pinctrl.yaml: \ properties:compatible:enum: ['aspeed', 'ast2400-pinctrl', 'aspeed', 'g4-pinctrl'] has non-unique elements Documentation/devicetree/bindings/pinctrl/aspeed,ast2500-pinctrl.yaml: \ properties:compatible:enum: ['aspeed', 'ast2500-pinctrl', 'aspeed', 'g5-pinctrl'] has non-unique elements Flow style sequences have to be quoted if the vales contain ','.

2019-07-20dt-bindings: riscv: Limit cpus schema to only check RiscV 'cpu' nodesRob Herring1-82/+61
Matching on the 'cpus' node was a bad choice because the schema is incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus schema which checks the general structure, it is also redundant to do so in the Risc-V CPU schema. The downside is one could conceivably mix different architecture's cpu nodes or have typos in the compatible string. The latter problem pretty much exists for every schema.

2019-07-20dt-bindings: Ensure child nodes are of type 'object'Rob Herring6-0/+8
Properties which are child node definitions need to have an explict type. Otherwise, a matching (DT) property can silently match when an error is desired. Fix this up tree-wide. Once this is fixed, the meta-schema will enforce this on any child node definitions.
