Merge tag 'mips_4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/mips

Pull MIPS updates from James Hogan:
 "These are the main MIPS changes for 4.17. Rough overview:

   (1) generic platform: Add support for Microsemi Ocelot SoCs

   (2) crypto: Add CRC32 and CRC32C HW acceleration module

   (3) Various cleanups and misc improvements

  More detailed summary:

  Miscellaneous:
   - hang more efficiently on halt/powerdown/restart
   - pm-cps: Block system suspend when a JTAG probe is present
   - expand make help text for generic defconfigs
   - refactor handling of legacy defconfigs
   - determine the entry point from the ELF file header to fix microMIPS
     for certain toolchains
   - introduce isa-rev.h for MIPS_ISA_REV and use to simplify other code

  Minor cleanups:
   - DTS: boston/ci20: Unit name cleanups and correction
   - kdump: Make the default for PHYSICAL_START always 64-bit
   - constify gpio_led in Alchemy, AR7, and TXX9
   - silence a couple of W=1 warnings
   - remove duplicate includes

  Platform support:
  Generic platform:
   - add support for Microsemi Ocelot
   - dt-bindings: Add vendor prefix for Microsemi Corporation
   - dt-bindings: Add bindings for Microsemi SoCs
   - add ocelot SoC & PCB123 board DTS files
   - MAINTAINERS: Add entry for Microsemi MIPS SoCs
   - enable crc32-mips on r6 configs

  ath79:
   - fix AR724X_PLL_REG_PCIE_CONFIG offset

  BCM47xx:
   - firmware: Use mac_pton() for MAC address parsing
   - add Luxul XAP1500/XWR1750 WiFi LEDs
   - use standard reset button for Luxul XWR-1750

  BMIPS:
   - enable CONFIG_BRCMSTB_PM in bmips_stb_defconfig for build coverage
   - add STB PM, wake-up timer, watchdog DT nodes

  Octeon:
   - drop '.' after newlines in printk calls

  ralink:
   - pci-mt7621: Enable PCIe on MT7688"

* Microsemi MIPS CPUs
Boards with a SoC of the Microsemi MIPS family shall have the following
properties:
Required properties:
- compatible: "mscc,ocelot"
* Other peripherals:
o CPU chip regs:
The SoC has a few registers (DEVCPU_GCB:CHIP_REGS) handling miscellaneous
functionalities: chip ID, general purpose register for software use, reset
controller, hardware status and configuration, efuses.
Required properties:
- compatible: Should be "mscc,ocelot-chip-regs", "simple-mfd", "syscon"
- reg : Should contain registers location and length
Example:
syscon@71070000 {
compatible = "mscc,ocelot-chip-regs", "simple-mfd", "syscon";
reg = <0x71070000 0x1c>;
};
o CPU system control:
The SoC has a few registers (ICPU_CFG:CPU_SYSTEM_CTRL) handling configuration of
the CPU: 8 general purpose registers, reset control, CPU en/disabling, CPU
endianness, CPU bus control, CPU status.
Required properties:
- compatible: Should be "mscc,ocelot-cpu-syscon", "syscon"
- reg : Should contain registers location and length
Example:
syscon@70000000 {
compatible = "mscc,ocelot-cpu-syscon", "syscon";
reg = <0x70000000 0x2c>;
};
