2018-07-25dt-bindings: remove 'interrupt-parent' from bindingsRob Herring9-21/+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.

Device tree binding document has been cleaned up. Device tree support in the driver has been improved and we now support all at24 models as well as two new DT properties (no-read-rollover and wp-gpios). We no longer user unreadable magic values for driver data as the way it was implemented caused problems for some EEPROM models - we switched to regular structs. Aside from that, there's a bunch of coding style fixes and minor improvements all over the place."

2017-11-06i2c: aspeed: Deassert reset in probeJoel Stanley1-2/+5
In order to use i2c from a cold boot, the i2c peripheral must be taken out of reset. We request a shared reset controller each time a bus driver is loaded, as the reset is shared between the 14 i2c buses. On remove the reset is asserted, which only touches the hardware once the last i2c bus is removed. The reset is required as the I2C buses will not work without releasing the reset. Previously the driver only worked with out of tree hacks that released this reset before the driver was loaded. Update the device tree bindings to reflect this.

2017-10-30dt-bindings: i2c: i2c-gpio: Add support for named gpiosGeert Uytterhoeven1-9/+23
The current i2c-gpio DT bindings use a single unnamed "gpios" property to refer to the SDA and SCL signal lines by index. This is error-prone for the casual DT writer and reviewer, as one has to look up the order in the DT bindings. Fix this by amending the DT bindings to use two separate named gpios properties, and deprecate the old unnamed variant. Take this opportunity to clearly deprecate the "i2c-gpio,sda-open-drain" and "i2c-gpio,scl-open-drain" flags as well. The commit describes in detail what these flags actually mean, and why they should not be used in new device trees.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM 64-bit DT updates from Arnd Bergmann: "Device-tree updates for arm64 platforms. For the first time I can remember, this is actually larger than the corresponding branch for 32-bit platforms overall, though that has more individual changes. A significant portion this time is due to added machine support: - Initial support for the Realtek RTD1295 SoC, along with the Zidoo X9S set-top-box - Initial support for Actions Semi S900 and the Bubblegum-96 single-board-cёmputer. - Rockchips support for the rk3399-Firefly single-board-computer gets added, this one stands out for being relatively fast, affordable and well₋supported, compared to many boards that only fall into one or two of the above categories. - Mediatek gains support for the mt6797 mobile-phone SoC platform and corresponding evaluation board. - Amlogic board support gets added for the NanoPi K2 and S905x LibreTech CC single-board computers and the R-Box Pro set-top-box - Allwinner board support gets added for the OrangePi Win, Orangepi Zero Plus 2, NanoPi NEO2 and Orange Pi Prime single board computers and the SoPine system-on-module. - Renesas board support for Salvator-XS and H3ULCB automotive development systems. - Socionext Uniphier board support for LD11-global and LD20-global, whatever those may be. - Broadcom adds support for the new Stingray communication processor in its iProc family, along with two reference boards. Other updates include: - For the hisicon platform, support for Hi3660-Hikey960 gets extended significantly. - Lots of smaller updates for Renesas, Amlogic, Rockchip, UniPhier, Broadcom, Allwinner, Hisilicon, Qualcomm, Marvell, and NXP" * tag 'armsoc-dt64' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (243 commits) ARM64: dts: marvell: armada37xx: Fix timer interrupt specifiers Revert "arm64: dts: marvell: add dma-mask in crypto nodes for 7k/8k" arm64: dts: mediatek: don't include missing file ARM64: dts: meson-gxl: Add Libre Technology CC support dt-bindings: arm: amlogic: Add Libre Technology CC board dt-bindings: add Libre Technology vendor prefix arm64: dts: marvell: enable GICP and ICU on Armada 7K/8K arm64: dts: zte: Use - instead of @ for DT OPP entries arm64: dts: marvell: add gpio support for Armada 7K/8K arm64: dts: marvell: add pinctrl support for Armada 7K/8K arm64: dts: marvell: use new binding for the system controller on cp110 arm64: dts: marvell: remove *-clock-output-names on cp110 arm64: dts: marvell: use new bindings for xor clocks on ap806 arm64: dts: marvell: mcbin: enable the mdio node arm64: dts: Add Actions Semi S900 and Bubblegum-96 dt-bindings: Add vendor prefix for uCRobotics arm64: dts: marvell: add xmdio nodes for 7k/8k arm64: dts: marvell: add a comment on the cp110 slave node status arm64: dts: marvell: remove cpm crypto nodes from dts files arm64: dts: marvell: cp110: enable the crypto engine at the SoC level ...
