Merge tag 'mips_5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux 

Pull MIPS updates from Paul Burton:

 - Support for the MIPSr6 MemoryMapID register & Global INValidate TLB
   (GINVT) instructions, allowing for more efficient TLB maintenance
   when running on a CPU such as the I6500 that supports these.

 - Enable huge page support for MIPS64r6.

 - Optimize post-DMA cache sync by removing that code entirely for
   kernel configurations in which we know it won't be needed.

 - The number of pages allocated for interrupt stacks is now calculated
   correctly, where before we would wastefully allocate too much memory
   in some configurations.

 - The ath79 platform migrates to devicetree.

 - The bcm47xx platform sees fixes for the Buffalo WHR-G54S board.

 - The ingenic/jz4740 platform gains support for appended devicetrees.

 - The cavium_octeon, lantiq, loongson32 & sgi-ip27 platforms all see
   cleanups as do various pieces of core architecture code.

Lantiq XWAY SoC GPHY binding
============================
This binding describes a software-defined ethernet PHY, provided by the RCU
module on newer Lantiq XWAY SoCs (xRX200 and newer).
-------------------------------------------------------------------------------
Required properties:
- compatible : Should be one of
"lantiq,xrx200a1x-gphy"
"lantiq,xrx200a2x-gphy"
"lantiq,xrx300-gphy"
"lantiq,xrx330-gphy"
- reg : Addrress of the GPHY FW load address register
- resets : Must reference the RCU GPHY reset bit
- reset-names : One entry, value must be "gphy" or optional "gphy2"
- clocks : A reference to the (PMU) GPHY clock gate
Optional properties:
- lantiq,gphy-mode : GPHY_MODE_GE (default) or GPHY_MODE_FE as defined in
<dt-bindings/mips/lantiq_xway_gphy.h>
-------------------------------------------------------------------------------
Example for the GPHys on the xRX200 SoCs:
#include <dt-bindings/mips/lantiq_rcu_gphy.h>
gphy0: gphy@20 {
compatible = "lantiq,xrx200a2x-gphy";
reg = <0x20 0x4>;
resets = <&reset0 31 30>, <&reset1 7 7>;
reset-names = "gphy", "gphy2";
clocks = <&pmu0 XRX200_PMU_GATE_GPHY>;
lantiq,gphy-mode = <GPHY_MODE_GE>;
};
