This patch add the binding documentation for the iommu and smi devices on the MT7623 SoC. Signed-off-by: Matthias Brugger <matthias.bgg@gmail.com>
This patch adds decriptions for mt2712 IOMMU and SMI.
In order to balance the bandwidth, mt2712 has two M4Us, two
smi-commons, 10 smi-larbs. and mt2712 is also MTK IOMMU gen2 which
uses ARM Short-Descriptor translation table format.
The mt2712 M4U-SMI HW diagram is as below:

Move the device tree bindings for the Tegra20 memory controller to the same location as the Tegra30 (and later) memory controller bindings. Signed-off-by: Thierry Reding <treding@nvidia.com>
Memory Controller has a memory client "hot reset" functionality, which resets the DMA interface of a memory client. So MC is a reset controller in addition to IOMMU.

Pull "Freescale arm64 device tree fixups for 4.17" from Shawn Guo: - It reverts a couple of patches that "fix" DTC warnings on IFC memory controller in a wrong way. We will start over agagin to address the DTC warnings later. * tag 'imx-dt64-4.17-2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux: Revert "dt-bindings: ifc: Fix the unit address format in the examples" Revert "arm64: dts: fsl: fix ifc simple-bus unit address format warnings"
This reverts commit 4e017f1419397473cf3db6e9fa020013998b1aa4. As explained by Rob Herring: "This "fix" is wrong. Memory controllers with chip selects should have the chip select in the unit-address. The correct fix here is you should drop "simple-bus"." Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

DTC warnings will be seen if these examples are used in a real dts file
due to a mismatch in the unit address notation.
Align the unit address notation to what is done in the real dts files
as per commit f81d7af79575 ("arm64: dts: fsl: fix ifc simple-bus unit
address format warnings")

Certain revisions of the TI EMIF IP contain ECC support in them. Reflect this in the DT binding. Also, add interrupts property as a required property for the emif controller, as all revisions of the emif IP contain interrupt support; this might remain unused by the kernel driver though.

Pull ARM SoC driver updates from Arnd Bergmann:
"A number of new drivers get added this time, along with many
low-priority bugfixes. The most interesting changes by subsystem are:
bus drivers:
- Updates to the Broadcom bus interface driver to support newer SoC
types
- The TI OMAP sysc driver now supports updated DT bindings
memory controllers:
- A new driver for Tegra186 gets added
- A new driver for the ti-emif sram, to allow relocating
suspend/resume handlers there
SoC specific:
- A new driver for Qualcomm QMI, the interface to the modem on MSM
SoCs
- A new driver for power domains on the actions S700 SoC
- A driver for the Xilinx Zynq VCU logicoreIP
reset controllers:
- A new driver for Amlogic Meson-AGX
- various bug fixes
tee subsystem:
- A new user interface got added to enable asynchronous communication
with the TEE supplicant.
- A new method of using user space memory for communication with the
TEE is added"
