2019-09-11gpio: aspeed: Update documentation with ast2600 controllersRashmica Gupta1-2/+5
The ast2600 is a new generation of SoC from ASPEED. Similarly to the ast2400 and ast2500, it has a GPIO controller for it's 3.3V GPIO pins. Additionally, it has a GPIO controller for 36 1.8V GPIO pins. We use the ngpio property to differentiate between these controllers.

2019-02-13dt-bindings: gpio: document the new pull-up/pull-down flagsThomas Petazzoni1-0/+12
This commit extends the flags that can be used in GPIO specifiers to indicate if a pull-up resistor or pull-down resistor should be enabled. While some pinctrl DT bindings already offer the capability of configuring pull-up/pull-down resistors at the pin level, a number of simple GPIO controllers don't have any pinmuxing capability, and therefore do not rely on the pinctrl DT bindings. Such simple GPIO controllers however sometimes allow to configure pull-up and pull-down resistors on a per-pin basis, and whether such resistors should be enabled or not is a highly board-specific HW characteristic. By using two additional bits of the GPIO flag specifier, we can easily allow the Device Tree to describe which GPIOs should have their pull-up or pull-down resistors enabled. Even though the two options are mutually exclusive, we still need two bits to encode at least three states: no pull-up/pull-down, pull-up, pull-down.

Being able to validate bindings has been discussed for years with little progress. - Initial support for DT bindings using json-schema language. This is the start of converting DT bindings from free-form text to a structured format. - Reworking of initrd address initialization. This moves to using the phys address instead of virt addr in the DT parsing code. This rework was motivated by CONFIG_DEV_BLK_INITRD causing unnecessary rebuilding of lots of files. - Fix stale phandle entries in phandle cache - DT overlay validation improvements. This exposed several memory leak bugs which have been fixed. - Use node name and device_type helper functions in DT code - Last remaining conversions to using %pOFn printk specifier instead of device_node.name directly - Create new common RTC binding doc and move all trivial RTC devices out of trivial-devices.txt. - New bindings for Freescale MAG3110 magnetometer, Cadence Sierra PHY, and Xen shared memory - Update dtc to upstream version v1.4.7-57-gf267e674d145" * tag 'devicetree-for-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (68 commits) of: __of_detach_node() - remove node from phandle cache of: of_node_get()/of_node_put() nodes held in phandle cache gpio-omap.txt: add reg and interrupts properties dt-bindings: mrvl,intc: fix a trivial typo dt-bindings: iio: magnetometer: add dt-bindings for freescale mag3110 dt-bindings: Convert trivial-devices.txt to json-schema dt-bindings: arm: mrvl: amend Browstone compatible string dt-bindings: arm: Convert Tegra board/soc bindings to json-schema dt-bindings: arm: Convert ZTE board/soc bindings to json-schema dt-bindings: arm: Add missing Xilinx boards dt-bindings: arm: Convert Xilinx board/soc bindings to json-schema dt-bindings: arm: Convert VIA board/soc bindings to json-schema dt-bindings: arm: Convert ST STi board/soc bindings to json-schema dt-bindings: arm: Convert SPEAr board/soc bindings to json-schema dt-bindings: arm: Convert CSR SiRF board/soc bindings to json-schema dt-bindings: arm: Convert QCom board/soc bindings to json-schema dt-bindings: arm: Convert TI nspire board/soc bindings to json-schema dt-bindings: arm: Convert TI davinci board/soc bindings to json-schema dt-bindings: arm: Convert Calxeda board/soc bindings to json-schema dt-bindings: arm: Convert Altera board/soc bindings to json-schema ...

2018-12-07dt-bindings: gpio: lpc18xx: describe interrupt controllers of GPIO controllerVladimir Zapolskiy1-9/+29
From LPC18xx and LPC43xx User Manuals the GPIO controller consists of the following weakly connected blocks: * GPIO pin interrupt block at 0x40087000, * GPIO GROUP0 interrupt block at 0x40088000, * GPIO GROUP1 interrupt block at 0x40089000, * GPIO port block at 0x400F4000. While all 4 sub-controller blocks have their own I/O addresses, moreover all 3 interrupt blocks are APB0 peripherals and high-speed GPIO block is an AHB slave, according to the hardware manual interrupt controllers and GPIO controller block are seen as a single device, all 4 sub-controllers have the shared reset signal RGU #28 and the same shared clock to access registers CLK_Mx_GPIO on CCU1. The change adds descriptions of the currently missing interrupt controller blocks found on GPIO controller, new added properties are 'reg-names', 'resets', 'interrupt-controller' and '#interrupt-cells', also the example is updated to reflect the changes in device tree binding description.

On some SoCs(e.g. MX7ULP), GPIO clock is gatable and maybe disabled by default. Users have to make sure it's enabled before being able to access controller registers, otherwise an external abort error may occur. Let's add the optional clocks property to handle this case. For ULP GPIO clock, it includes two separate clocks: one is for GPIO controller Input/Output function clock while another is GPIO port control clock for interrupt function.

In 2011 the commit bf859f84a19f ("gpio/dt: Refine GPIO device tree binding") introduced an experimental BNF notation for defining a regular grammar for the GPIO phandles used by different devices. This was an interesting approach, and shows that we have long nutured the idea to formally verify device tree files using regular grammar. Most if not all other bindings use natural language to define the bindings, and the recent thinking for verifying device tree files is to use JSON schemas in separate definitions. Cut the BNF business and replace it with natural language so that it becomes more human-readable for now.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.19 kernel cycle. I don't know if anything in particular stands out. Maybe the Aspeed coprocessor thing from Benji: Aspeed is doing baseboard management chips (BMC's) for servers etc. These Aspeed's are ARM processors that exist inside (I guess) Intel servers, and they are moving forward to using mainline Linux in those. This is one of the pieces of the puzzle to achive that. They are doing OpenBMC, it's pretty cool: https://lwn.net/Articles/683320/ Summary: Core changes: - Add a new API for explicitly naming GPIO consumers, when needed. - Don't let userspace set values on input lines. While we do not think anyone would do this crazy thing we better plug the hole before someone uses it and think it's a nifty feature. - Avoid calling chip->request() for unused GPIOs. New drivers/subdrivers: - The Mediatek MT7621 is supported which is a big win for OpenWRT and similar router distributions using this chip, as it seems every major router manufacturer on the planet has made products using this chip: https://wikidevi.com/wiki/MediaTek_MT7621 - The Tegra 194 is now supported. - The IT87 driver now supports IT8786E and IT8718F super-IO chips. - Add support for Rockchip RK3328 in the syscon GPIO driver. Driver changes: - Handle the get/set_multiple() properly on MMIO chips with inverted direction registers. We didn't have this problem until a new chip appear that has get/set registers AND inverted direction bits, OK now we handle it. - A patch series making more error codes percolate upward properly for different errors on gpiochip_lock_as_irq(). - Get/set multiple for the OMAP driver, accelerating these multiple line operations if possible. - A coprocessor interface for the Aspeed driver. Sometimes a few GPIO lines need to be grabbed by a co-processor for doing automated tasks, sometimes they are available as GPIO lines. By adding an explicit API in this driver we make it possible for the two line consumers to coexist. (This work was made available on the ib-aspeed branch, which may be appearing in other pull requests.) - Implemented .get_direction() and open drain in the SCH311x driver. - Continuing cleanup of included headers in GPIO drivers" * tag 'gpio-v4.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (80 commits) gpio: it87: Add support for IT8613 gpio: it87: add support for IT8718F Super I/O. gpiolib: Avoid calling chip->request() for unused gpios gpio: tegra: Include the right header gpio: mmio: Fix up inverted direction registers gpio: xilinx: Use the right include gpio: timberdale: Include the right header gpio: tb10x: Use the right include gpiolib: Fix of_node inconsistency gpio: vr41xx: Bail out on gpiochip_lock_as_irq() error gpio: uniphier: Bail out on gpiochip_lock_as_irq() error gpio: xgene-sb: Don't shadow error code of gpiochip_lock_as_irq() gpio: em: Don't shadow error code of gpiochip_lock_as_irq() gpio: dwapb: Don't shadow error code of gpiochip_lock_as_irq() gpio: bcm-kona: Don't shadow error code of gpiochip_lock_as_irq() gpiolib: Don't shadow error code of gpiochip_lock_as_irq() gpio: syscon: rockchip: add GRF GPIO support for rk3328 gpio: omap: Add get/set_multiple() callbacks gpio: pxa: remove set but not used variable 'gpio_offset' gpio-it87: add support for IT8786E Super I/O ...

It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

2018-05-16gpio: dwapb: Add support for 1 interrupt per port A GPIOPhil Edworthy1-2/+7
The DesignWare GPIO IP can be configured for either 1 interrupt or 1 per GPIO in port A, but the driver currently only supports 1 interrupt. See the DesignWare DW_apb_gpio Databook description of the 'GPIO_INTR_IO' parameter. This change allows the driver to work with up to 32 interrupts, it will get as many interrupts as specified in the DT 'interrupts' property. It doesn't do anything clever with the different interrupts, it just calls the same handler used for single interrupt hardware. ACPI companion code provided by Hoan Tran <hotran@apm.com>. This was tested on X-Gene by Hoan.
