Various examples are fixed due to that. - Sync dtc with upstream version v1.5.0-30-g702c1b6c0e73 - Initial schemas for networking bindings. This includes ethernet, phy and mdio common bindings with several Allwinner and stmmac converted to the schema. - Conversion of more Arm top-level SoC/board bindings to DT schema - Conversion of PSCI binding to DT schema - Rework Arm CPU schema to coexist with other CPU schemas - Add a bunch of missing vendor prefixes and new ones for SoChip, Sipeed, Kontron, B&R Industrial Automation GmbH, and Espressif - Add Mediatek UART RX wakeup support to binding - Add reset to ST UART binding - Remove some Linuxisms from the endianness common-properties.txt binding - Make the flattened DT read-only after init - Ignore disabled reserved memory nodes - Clean-up some dead code in FDT functions * tag 'devicetree-for-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (56 commits) dt-bindings: vendor-prefixes: add Sipeed dt-bindings: vendor-prefixes: add SoChip dt-bindings: 83xx-512x-pci: Drop cell-index property dt-bindings: serial: add documentation for Rx in-band wakeup support dt-bindings: arm: Convert RDA Micro board/soc bindings to json-schema of: unittest: simplify getting the adapter of a client of/fdt: pass early_init_dt_reserve_memory_arch() with bool type nomap of/platform: Drop superfluous cast in of_device_make_bus_id() dt-bindings: usb: ehci: Fix example warnings dt-bindings: net: Use phy-mode instead of phy-connection-type dt-bindings: simple-framebuffer: Add requirement for pipelines dt-bindings: display: Fix simple-framebuffer example dt-bindings: net: mdio: Add child nodes dt-bindings: net: mdio: Add address and size cells dt-bindings: net: mdio: Add a nodename pattern dt-bindings: mtd: sunxi-nand: Drop 'maxItems' from child 'reg' property dt-bindings: arm: Limit cpus schema to only check Arm 'cpu' nodes dt-bindings: backlight: lm3630a: correct schema validation dt-bindings: net: dwmac: Deprecate the PHY reset properties dt-bindings: net: sun8i-emac: Convert the binding to a schemas ...

| * dt-bindings: arm: Limit cpus schema to only check Arm 'cpu' nodesRob Herring2019-06-281-263/+224
| | | | | | | | | | | | | | | | | | | | | | | | | | Matching on the 'cpus' node was a bad choice because the schema is incorrectly applied to non-Arm cpus nodes. As we now have a common cpus schema which checks the general structure, it is also redundant to do so in the Arm CPU schema. The downside is one could conceivably mix different architecture's cpu nodes or have typos in the compatible string. The latter problem pretty much exists for every schema.

TMIO (Toshiba Mobile IO) MMC was the first upstreamed user of this IP. The common driver code was split and expanded as 'tmio-mmc-core', then it became historical misnomer since 'tmio' is not the name of this IP. In the discussion [1], we decide to keep this name as-is at least in Linux driver level because renaming everything is a big churn. However, DT should not be oriented to a particular project even though it is mainly developed in Linux communities. This is the misfortune only in Linux. Let's stop exporting it to other projects, where there is no good reason to call this hardware "TMIO". Rename the file to renesas,sdhi.txt. In fact, all the information in this file is specific to the Renesas platform. This commit also removes the first paragraph entirely. The DT-binding should describe the hardware. It is strange to talk about Linux driver internals such as how the drivers are probed, how platform data are handed off, etc. [1] https://www.spinics.net/lists/linux-mmc/msg46952.html Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Horman <horms+renesas@verge.net.au> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
