While my email address has changed for a while, all the schemas I contributed still have the old one unfortunately. Update it. Signed-off-by: Maxime Ripard <maxime@cerno.tech> Signed-off-by: Rob Herring <robh@kernel.org>
2019-10-15dt-bindings: serio: Convert Allwinner PS2 controller to a schemaMaxime Ripard
The older Allwinner SoCs have a PS2 controller that is supported in Linux, with a matching Device Tree binding. Now that we have the DT validation in place, let's convert the device tree bindings for that controller over to a YAML schemas.

2019-01-24Revert "Input: olpc_apsp - enable the SP clock"Lubomir Rintel
Turns out this is not such a great idea. Once the SP clock is disabled, it's not sufficient to just enable in order to bring the SP core back up. It seems that the kernel has no business managing this clock. Just let the firmware keep it enabled. This reverts commit ed22cee91a88c47e564478b012fdbcb079653499.

git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux Pull DeviceTree updates from Rob Herring: "There's a few orphans in the conversion to %pOF printf specifiers included here that no one else picked up. Summary: - Convert more DT code to use of_property_read_* API. - Improve DT overlay support when adding multiple overlays - Convert printk's to %pOF format specifiers. Most went via subsystem trees, but picked up the remaining orphans - Correct unittests to use preferred "okay" for "status" property value - Add a KASLR seed property - Vendor prefixes for Mellanox, Theobroma System, Adaptrum, Moxa - Fix modalias buffer handling - Clean-up of include paths for building dtbs - Add bindings for amc6821, isl1208, tsl2x7x, srf02, and srf10 devices - Add nvmem bindings for MediaTek MT7623 and MT7622 SoC - Add compatible string for Allwinner H5 Mali-450 GPU - Fix links to old OpenFirmware docs with new mirror on devicetree.org - Remove status property from binding doc examples" * tag 'devicetree-for-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (45 commits) devicetree: Adjust status "ok" -> "okay" under drivers/of/ dt-bindings: Remove "status" from examples dt-bindings: pinctrl: sh-pfc: Use generic node name dt-bindings: Add vendor Mellanox dt-binding: net/phy: fix interrupts description virt: Convert to using %pOF instead of full_name macintosh: Convert to using %pOF instead of full_name ide: pmac: Convert to using %pOF instead of full_name microblaze: Convert to using %pOF instead of full_name dt-bindings: usb: musb: Grammar s/the/to/, s/is/are/ of: Use PLATFORM_DEVID_NONE definition of/device: Fix of_device_get_modalias() buffer handling of/device: Prevent buffer overflow in of_device_modalias() dt-bindings: add amc6821, isl1208 trivial bindings dt-bindings: add vendor prefix for Theobroma Systems of: search scripts/dtc/include-prefixes path for both CPP and DTC of: remove arch/$(SRCARCH)/boot/dts from include search path for CPP of: remove drivers/of/testcase-data from include search path for CPP of: return of_get_cpu_node from of_cpu_device_node_get if CPUs are not registered iio: srf08: add device tree binding for srf02 and srf10 ...
2017-09-05dt-bindings: Remove "status" from examplesRob Herring
Pretty much any node can have a status property, so it doesn't need to be in examples. Converted with the following command and removed examples with SoC and board specific splits: git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d' Acked-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Rob Herring <robh@kernel.org>
2017-08-28Input: PS/2 gpio bit banging driver for serio busDanilo Krummrich
This driver provides PS/2 serio bus support by implementing bit banging with the GPIO API. The GPIO pins, data and clock, can be configured with a node in the device tree or by generic device properties (GDP). Writing to a device is supported as well, though it is possible timings can not be halt as they are tough and difficult to reach with bit banging. Therefore it can be configured (also in DT and GDP) whether the serio write function should be available for clients. This driver is for development purposes and not recommended for productive use. However, this driver can be useful e.g. when no USB port is available or using old peripherals is desired as PS/2 controller chips getting rare. This driver was tested on bcm2825 and on Kirin 960 and it worked well together with the atkbd and psmouse driver.

2013-06-30Input: add OLPC AP-SP driverDaniel Drake
The OLPC XO-1.75 and XO-4 laptops include a PS/2 touchpad and an AT keyboard, yet they do not have a hardware PS/2 controller. Instead, a firmware runs on a dedicated core ("Security Processor", part of the SoC) that acts as a PS/2 controller through bit-banging. Communication between the main cpu (Application Processor) and the Security Processor happens via a standard command mechanism implemented by the SoC. Add a driver for this interface to enable keyboard/mouse input on this platform.
