Pull DeviceTree updates from Rob Herring: - fix sparse warnings in drivers/of/ - add more overlay unittests - update dtc to v1.4.4-8-g756ffc4f52f6. This adds more checks on dts files such as unit-address formatting and stricter character sets for node and property names - add a common DT modalias function - move trivial-devices.txt up and out of i2c dir - ARM NVIC interrupt controller binding - vendor prefixes for Sensirion, Dioo, Nordic, ROHM - correct some binding file locations * tag 'devicetree-for-4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (24 commits) of: fix sparse warnings in fdt, irq, reserved mem, and resolver code of: fix sparse warning in of_pci_range_parser_one of: fix sparse warnings in of_find_next_cache_node of/unittest: Missing unlocks on error of: fix uninitialized variable warning for overlay test of: fix unittest build without CONFIG_OF_OVERLAY of: Add unit tests for applying overlays of: per-file dtc compiler flags fpga: region: add missing DT documentation for config complete timeout of: Add vendor prefix for ROHM Semiconductor of: fix "/cpus" reference leak in of_numa_parse_cpu_nodes() of: Add vendor prefix for Nordic Semiconductor dt-bindings: arm,nvic: Binding for ARM NVIC interrupt controller on Cortex-M dtc: update warning settings for new bus and node/property name checks scripts/dtc: Update to upstream version v1.4.4-8-g756ffc4f52f6 scripts/dtc: automate getting dtc version and log in update script of: Add function for generating a DT modalias with a newline of: fix of_device_get_modalias returned length when truncating buffers Documentation: devicetree: move trivial-devices out of I2C realm dt-bindings: add vendor prefix for Dioo ..

Merge branch 'i2c-mux/for-next' of https://github.com/peda-r/i2c-mux into i2c/for-4.12

2017-04-16T19:44:37Z

Pull in changes from the i2c-mux subsubsystem: "Here are a new LTC4306/5 driver, a fix needed by the RT kernel and some error message cleanup."

dt-bindings: i2c: mux: ltc4306: Add dt-bindings for I2C multiplexer/switch

2017-04-12T15:06:05Z

This patch adds support for the Analog Devices / Linear Technology LTC4306 and LTC4305 4/2 Channel I2C Bus Multiplexer/Switches. The LTC4306 optionally provides two general purpose input/output pins (GPIOs) that can be configured as logic inputs, opendrain outputs or push-pull outputs via the generic GPIOLIB framework.

i2c: meson: use i2c core for DT clock-frequency parsing

2017-03-30T15:30:47Z

We don't have to parse the DT manually to retrieve the bus frequency and we don't have to maintain an own default for the bus frequency. Let the i2c core do this for us. Signed-off-by: Heiner Kallweit Reviewed-by: Jerome Brunet Signed-off-by: Wolfram Sang

Documentation: devicetree: move trivial-devices out of I2C realm

2017-03-21T19:45:40Z

The I2C directory is for I2C master controllers, not for clients. So, move the file describing trivial devices one layer upwards where it fits its generic nature way better. Signed-off-by: Wolfram Sang Signed-off-by: Rob Herring

Pull i2c updates from Wolfram Sang: "I2C has for you two new drivers (Tegra BPMP and STM32F4), interrupt support for pca954x muxes, and a bunch of driver bugfixes and improvements. Nothing really special this cycle. A few commits have been added to my tree just recently. Those are the Tegra BPMP driver and a few straightforward bugfixes or cleanups which I prefer to have upstream rather soonish.

dt-bindings: Add Tegra186 BPMP I2C binding

2017-02-20T18:12:10Z

In Tegra186, the BPMP (Boot and Power Management Processor) owns certain HW devices, such as the I2C controller for the power management I2C bus. Software running on other CPUs must perform IPC to the BPMP in order to execute transactions on that I2C bus. This binding describes an I2C bus that is accessed in such a fashion.
