* dt-bindings: gpio: rcar: Convert to json-schemaGeert Uytterhoeven2020-05-121-94/+0
| | | | | | | | | | | | | Convert the Renesas General-Purpose Input/Output Ports (GPIO) Device Tree binding documentation to json-schema. Drop the deprecated "renesas,gpio-rcar" compatible value. Document missing properties. Drop the first example, as it doesn't add much value.

Update all references to R-Car M3-W from "r8a7796" to "r8a77960", to avoid confusion between R-Car M3-W (R8A77960) and M3-W+. No driver update is needed.

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 ...

* | dt-bindings: remove 'interrupt-parent' from bindingsRob Herring2018-07-251-1/+0
|/ | | | | | | | | | | | 'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. 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.

* gpio: rcar: add gen[123] fallback compatibility stringsSimon Horman2017-08-141-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | Add fallback compatibility string for R-Car Gen 1, 2 and 3. In the case of Renesas R-Car hardware we know that there are generations of SoCs, f.e. Gen 1 and 2. But beyond that its not clear what the relationship between IP blocks might be. For example, I believe that r8a7790 is older than r8a7791 but that doesn't imply that the latter is a descendant of the former or vice versa. We can, however, by examining the documentation and behaviour of the hardware at run-time observe that the current driver implementation appears to be compatible with the IP blocks on SoCs within a given generation. For the above reasons and convenience when enabling new SoCs a per-generation fallback compatibility string scheme being adopted for drivers for Renesas SoCs. Also deprecate renesas,gpio-rcar as its name is more generic than its implementation.
