git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux Pull Devicetree updates from Rob Herring: "A bit bigger than normal as I've been busy this cycle. There's a few things with dependencies and a few things subsystem maintainers didn't pick up, so I'm taking them thru my tree. The fixes from Johan didn't get into linux-next, but they've been waiting for some time now and they are what's left of what subsystem maintainers didn't pick up. Summary: - Sync dtc with upstream version v1.4.7-14-gc86da84d30e4 - Work to get rid of direct accesses to struct device_node name and type pointers in preparation for removing them. New helpers for parsing DT cpu nodes and conversions to use the helpers. printk conversions to %pOFn for printing DT node names. Most went thru subystem trees, so this is the remainder. - Fixes to DT child node lookups to actually be restricted to child nodes instead of treewide. - Refactoring of dtb targets out of arch code. This makes the support more uniform and enables building all dtbs on c6x, microblaze, and powerpc. - Various DT binding updates for Renesas r8a7744 SoC - Vendor prefixes for Facebook, OLPC - Restructuring of some ARM binding docs moving some peripheral bindings out of board/SoC binding files - New "secure-chosen" binding for secure world settings on ARM - Dual licensing of 2 DT IRQ binding headers" * tag 'devicetree-for-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (78 commits) ARM: dt: relicense two DT binding IRQ headers power: supply: twl4030-charger: fix OF sibling-node lookup NFC: nfcmrvl_uart: fix OF child-node lookup net: stmmac: dwmac-sun8i: fix OF child-node lookup net: bcmgenet: fix OF child-node lookup drm/msm: fix OF child-node lookup drm/mediatek: fix OF sibling-node lookup of: Add missing exports of node name compare functions dt-bindings: Add OLPC vendor prefix dt-bindings: misc: bk4: Add device tree binding for Liebherr's BK4 SPI bus dt-bindings: thermal: samsung: Add SPDX license identifier dt-bindings: clock: samsung: Add SPDX license identifiers dt-bindings: timer: ostm: Add R7S9210 support dt-bindings: phy: rcar-gen2: Add r8a7744 support dt-bindings: can: rcar_can: Add r8a7744 support dt-bindings: timer: renesas, cmt: Document r8a7744 CMT support dt-bindings: watchdog: renesas-wdt: Document r8a7744 support dt-bindings: thermal: rcar: Add device tree support for r8a7744 Documentation: dt: Add binding for /secure-chosen/stdout-path dt-bindings: arm: zte: Move sysctrl bindings to their own doc ...
2018-10-23power: supply: twl4030-charger: fix OF sibling-node lookupJohan Hovold1-2/+3
Use the new of_get_compatible_child() helper to lookup the usb sibling node instead of using of_find_compatible_node(), which searches the entire tree from a given start node and thus can return an unrelated (non-sibling) node. This also addresses a potential use-after-free (e.g. after probe deferral) as the tree-wide helper drops a reference to its first argument (i.e. the parent device node). While at it, also fix the related phy-node reference leak. Fixes: f5e4edb8c888 ("power: twl4030_charger: find associated phy by more reliable means.")

2018-09-16power: supply: cros: add support for dedicated portFabien Parent1-14/+101
ChromeOS devices can have one optional dedicated port. The Dedicated port is unique and similar to the USB PD ports except that it doesn't support as many properties. The presence of a dedicated port is determined from whether the EC's charger port count is equal to 'number of USB PD port' + 1. The dedicated port ID is always the last valid port ID. This commit keeps compatibility with Embedded Controllers that do not support the new EC_CMD_CHARGE_PORT_COUNT command by setting the number of charger port to be equal to the number of USB PD port when this command fails.

2018-09-16power: reset: at91-poweroff: switch to slow clock before shutdownClaudiu Beznea1-8/+58
The SAMA5D2 NRST input signal is resynchronized with the SLCK clock and it can take up to 2 SLCK cycles (about 90us) for the internal reset to be effective. During this delay, the VDDCORE current consumption may still be high (application-dependent) with the VDDCORE regulator already OFF. Under such conditions, VDDCORE may operate below its operating range leading to potential register corruption. To prevent such situation, it is recommended to decrease significantly the power consumption of the device once the voltage regulator is turned-off. This can be achieved by operating the device at a much lower low frequency. To solve this switch the master clock to slock clock just before writing shutdown command to shutdown controller.
