      riscv: dts: microchip: mpfs: remove bogus card-detect-delay · 2b55915d
      Conor Dooley authored 
      Recent versions of dt-schema warn about a previously undetected
undocumented property:
arch/riscv/boot/dts/microchip/mpfs-icicle-kit.dtb: mmc@20008000: Unevaluated properties are not allowed ('card-detect-delay' was unexpected)
        From schema: Documentation/devicetree/bindings/mmc/cdns,sdhci.yaml

There are no GPIOs connected to MSSIO6B4 pin K3 so adding the common
cd-debounce-delay-ms property makes no sense. The Cadence IP has a
register that sets the card detect delay as "DP * tclk". On MPFS, this
clock frequency is not configurable (it must be 200 MHz) & the FPGA
comes out of reset with this register already set.

      Recent versions of dt-schema warn about a previously undetected
undocument property on the icicle & polarberry devicetrees:

        From schema: Documentation/devicetree/bindings/net/cdns,macb.yaml

I know what you're thinking, the binding doesn't look to be the problem
and I agree. I am not sure why a TI vendor property was ever actually
added since it has no meaning... just get rid of it.

      Recent versions of dt-schema complain about the PCIe controller's child

Make the dts match the correct property name in the dts.

      riscv: dts: microchip: correct L2 cache interrupts · 34fc9cc3
      Heinrich Schuchardt authored 
      The "PolarFire SoC MSS Technical Reference Manual" documents the
following PLIC interrupts:

1 - L2 Cache Controller Signals when a metadata correction event occurs
2 - L2 Cache Controller Signals when an uncorrectable metadata event occurs
3 - L2 Cache Controller Signals when a data correction event occurs
4 - L2 Cache Controller Signals when an uncorrectable data event occurs

This differs from the SiFive FU540 which only has three L2 cache related
interrupts.

The sequence in the device tree is defined by an enum:

    enum {
            DIR_CORR = 0,
            DATA_CORR,
            DATA_UNCORR,
            DIR_UNCORR,
    };

So the correct sequence of the L2 cache interrupts is

    interrupts = <1>, <3>, <4>, <2>;

[Conor]
This manifests as an unusable system if the l2-cache driver is enabled,
as the wrong interrupt gets cleared & the handler prints errors to the
console ad infinitum.

 "There's still a handful of new features in here, but there are a lot
  of fixes/cleanups as well:

   - Support for the Zicbom extension for explicit cache-block
     management, along with the necessary bits to make the non-standard
     cache management ops on the Allwinner D1 function

   - Support for the Zihintpause extension, which codifies a go-slow
     instruction used for cpu_relax()

   - Support for the Sstc extension for supervisor-mode timer/counter
     management

   - Many device tree fixes and cleanups, including a large set for the
     Canaan device trees

   - A handful of fixes and cleanups for the PMU driver"
