Arnd Bergmann f02e0468c4 Renesas ARM64 Based SoC DT Updates for v4.17
* R-Car Gen3 boards and SoCs
   - Make phy-mode of EtherAVB a board-specific property.
 
     The SoC DTs file now uses "rgmii" and boards override this with
     "rgmii-txid" as appropriate. Previously "rgmii-txid" was used
     in SoC DTs but this did not describe that more sophiticated
     functionality is a board rather than SoC property.
 
 * Condor board with R-Car V3H (r8a77980) SoC
   - Initial upstream support
 
 * Condor board with R-Car V3H (r8a77980) SoC
   - Initial upstream support
 
 * R-Car D3 (r8a77995)
   - Add I2C nodes and then describing the PCA9654 I/O expander connected to
     the I2C0 bus.
 
 * Eagle board with R-Car V3M (r8a77970) SoC
   - Enable PFC support for configuring SCIF0 pins
     This uses PFC support added to the V3M DT
 
   - Describe EtherAVB PHY IRQ
     This uses support for GPIO added to the V3M DT
 
   - Enable I2C0 support
 
     Sergei Shtylyov says "The I2C0 bus is populated by ON Semiconductor
     PCA9653 I/O expander and Analog Devices ADV7511W HDMI transmitter (but
     we're only describing the former chip now)."
 
 * R-Car V3M (r8a77970) SoCs
   - Add PFC support
   - Describe GPIO devices
   - Describe I2C devices
   - Srt subnodes of root node alphabetically to eas future maintence overhead
 
 * Draak board with R-Car D3 (r8a77995) SoC
   - Enable SDHI2
 
     Wolfram Sang says "The single SDHI controller is connected to eMMC."
 
   - Enable DU
 
     Kieran Bingham says "Enable the DU, providing only the VGA output for
     now."
 
 * R-Car D3 (r8a77995) and V3M (r8a77970) SoCs
   - Move nodes which have no reg property out of bus
     By deffinition the bus only has hardware with an address on the bus
 
   - Remove non-existing STBE region from EtherAVB
     Stream Buffer for EtherAVB-IF (STBE) is not present on these SoCs
 
 * R-Car D3 (r8a77995) SoC
   - Add FCPV, VSP and DU support
 
     Kieran Bingham says "The r8a77995-d3 platform supports 3 VSP instances.
     One VSPBS can be used as a dual-input image blender, while two VSPD
     instances can be utilised as part of a display (DU) pipeline.
 
     Add support for these, along with their required FCPV nodes."
 
 * Salvator-X and Salvator-XS boards with R-Car Gen3 SoCs
   - Add GPIO extender
     This is a basis for follow-up work to configure the GPIOs of the extender
 
 * Salvator-X and Salvator-XS board with R-Car M3-N (r8a77965) SoC
   - Initial upstream support
 
 * R-Car H3 (r8a7795) and M3-W (r8a7796) SoCs
   - Add OPPs table for cpu devices
     This, along with recently upstreamed Z and Z2 clock support allows
     use of CPUFreq with both A57 and A53 CPUs.
 
   - Add thermal cooling management
     Allows the use of CPUFreq as a cooling device on A57 CPUs
 
   - Correct register size of thermal node
 
     Niklas Söderlund says "To be able to read fused calibration values from
     hardware the size of the register resource of TSC1 needs to be
     incremented to cover one more register which holds the information if
     the calibration values have been fused or not.
 
     Instead of increasing TSC1 size to the value from the datasheet update
     all TSC's size to the smallest granularity of the address decoder
     circuitry"
 
   - Fix register mappings on VSPs
 
     Kieran Bingham says "The VSPD includes a CLUT on RPF2. Ensure that the
     register space is mapped correctly to support this."
 
 * R-Car H3 (r8a7795) SoC
   - Move SCIF node into alphabetical order to ease future maintenance overhead
 
   - Add IPMMU-PV1 device node
 
     This resolves an oversight when IPMMU nodes were added to the H3 DT.
     All IPMMU devices should now be described in DT.
 
   - Add missing SYS-DMAC2 dmas
 
     Geert Uytterhoeven says "On R-Car H3, on-chip peripheral modules that
     can make use of DMA are wired to either SYS-DMAC0 only, or to both
     SYS-DMAC1 and SYS-DMAC2.
 
     Add the missing DMA properties pointing to SYS-DMAC2 for HSCIF[0-2],
     SCIF[0125], and I2C[0-2].  These were initially left out because early
     firmware versions prohibited using SYS-DMAC2.  This restriction has
     been lifted in IPL and Secure Monitor Rev1.0.6 (released on Feb 25,
     2016)."

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
