ARM: dts: mmp2-olpc-xo-1-75: Use plural form of "-gpios"

2020-10-26T09:49:17+00:00

This makes validation happier. Link: https://lore.kernel.org/r/20200925234805.228251-3-lkundrak@v3.sk Signed-off-by: Lubomir Rintel Signed-off-by: Arnd Bergmann

ARM: dts: mmp2-olpc-xo-1-75: Enable the GPU

2020-07-22T20:05:20+00:00

Enable the 3D + 2D (GC860) GPU core. Link: https://lore.kernel.org/r/20200718205019.184927-12-lkundrak@v3.sk Signed-off-by: Lubomir Rintel Signed-off-by: Arnd Bergmann

ARM: dts: mmp2-olpc-xo-1-75: Enable audio support

2020-07-22T20:05:15+00:00

This enables the audio SRAM, DMA engine, I2S interface, and codec, hooks them together and adds a audio-graph-card instance. It also removes the jack gpios from the gpio-keys instance, because the audio jack driver registers an input device.

ARM: dts: mmp2-olpc-xo-1-75: Delete #address-cells from ssp3

2020-07-22T20:04:57+00:00

On the XO-1.75, this node represents a bus interface that operates in slave mode and thus is only able to accommodate a single subnode; no address cells are necessary. The Documentation/devicetree/bindings/spi/spi-controller.yaml binding prefers that we drop the property instead of setting it to zero. This fixes a DT validation error: arch/arm/boot/dts/mmp2-olpc-xo-1-75.dt.yaml: spi@d4037000: { ... } is valid under each of {'required': ['spi-slave']}, {'required': ['#address-cells']} We also need to drop #size-cells: arch/arm/boot/dts/mmp2-olpc-xo-1-75.dt.yaml: spi@d4037000: '#address-cells' is a dependency of '#size-cells' Link: https://lore.kernel.org/r/20200718205019.184927-3-lkundrak@v3.sk Signed-off-by: Lubomir Rintel Signed-off-by: Arnd Bergmann

ARM: dts: mmp2-olpc-xo-1-75: Fix camera I2C node validation

2020-07-22T20:04:54+00:00

mmp2-olpc-xo-1-75.dt.yaml: camera_i2c: $nodename:0: 'camera_i2c' does not match '^i2c(@.*)?' mmp2-olpc-xo-1-75.dt.yaml: camera_i2c: 'sda-gpios' is a required property mmp2-olpc-xo-1-75.dt.yaml: camera_i2c: 'scl-gpios' is a required property The "gpios" property actually was documented as deprecated, but got dropped in commit 0175ce4a58d6 ("dt-bindings: i2c: Convert i2c-gpio binding to json-schema"). It's probably best kept forgotten though. Link: https://lore.kernel.org/r/20200718205019.184927-2-lkundrak@v3.sk Signed-off-by: Lubomir Rintel Signed-off-by: Arnd Bergmann

ARM: dts: mmp2: add OLPC XO 1.75 machine

2019-09-07T19:54:11+00:00

This is a fairly complete description of an OLPC XO 1.75 laptop. What's missing for now is the GPU, LCD controller, DCON, the panel and audio. The machine is booted with OpenFirmware and thus has a devicetree. However, older versions are unable to create a valid FDT and don't follow the Linux bindings. Having an device tree in the kernel tree makes it easier to use mainline kernels on such machines, test changes with CONFIG_ARM_APPENDED_DTB and give a good reference on what bindings are used on the machine without an access to one.
