2019-02-20power: reset: at91-reset: add support for sam9x60 SoCNicolas Ferre

2019-02-20max17042_battery: fix potential use-after-free on device removeSven Van Asbroeck
The work which is scheduled on a POR boot is potentially left pending or running until after the device module is removed, which could result in a use-after-free. Fix by registering a cancel/sync callback, which gets executed as part of standard resource unwinding. This issue was detected with the help of Coccinelle.

2019-02-12power: supply: ds2782: fix possible use-after-free on removeSven Van Asbroeck
In remove(), use cancel_delayed_work_sync() to cancel the delayed work. Otherwise there's a chance that this work will continue to run until after the device has been removed. While we're here, fix the deallocation order in remove(), to correspond to the inverse of the probe() allocation order. This guarantees that any remaining work can run to completion with all driver structures still intact. This issue was detected with the help of Coccinelle.

2019-01-23power: supply: sc27xx: Fix capacity saving functionYuanjiang Yu
We found sometimes we can not get the saving capacity to initialize the battery capacity, the reason is the user area registers are put on power always-on region, so we need delay some time to wait until values are updated successfully. Moreover we also should clear the USER_AREA_CLEAR register after setting the USER_AREA_SET register, otherwise we can not save the values in the USER_AREA_SET register.

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 ...
