[PATCH v2 0/8] Add JH7100 errata and update device tree

[PATCH v2 0/8] Add JH7100 errata and update device tree

[Emil Renner Berthing]

Now that the driver for the SiFive cache controller supports manual
flushing as non-standard cache operations[1] we can add an errata option
for the StarFive JH7100 SoC and update the device tree with the cache
controller, dedicated DMA pool and add MMC nodes for the SD-card and
wifi.

This series needs the following commit in [1] to work properly:

0d5701dc9cd6 ("soc: sifive: ccache: Add StarFive JH7100 support")

..and its parent for dtb_checks to pass.

[1]: https://git.kernel.org/pub/scm/linux/kernel/git/conor/linux.git/log/?h=riscv-soc-for-next

Changes in v2:
- Add Conor's ack on patch 1/8
- Add my SoB on patch 2/8
- Update commit message on patch 4/8

[PATCH v2 1/8] riscv: errata: Add StarFive JH7100 errata

[Emil Renner Berthing]

This not really an errata, but since the JH7100 was made before
the standard Zicbom extension it needs the DMA_GLOBAL_POOL and
RISCV_NONSTANDARD_CACHE_OPS enabled to work correctly.

Thanks for dealing with this.  This is mostly DT stuff so I'm fine with 
it going via Conor's tree, but LMK if you guys want me to take it.

[PATCH v2 2/8] riscv: dts: starfive: Group tuples in interrupt properties

[Emil Renner Berthing]

From: Geert Uytterhoeven <geert@linux-m68k.org>

To improve human readability and enable automatic validation, the tuples
in the various properties containing interrupt specifiers should be
grouped.

Fix this by grouping the tuples of "interrupts-extended" properties
using angle brackets.

[PATCH v2 5/8] riscv: dts: starfive: Add pool for coherent DMA memory on JH7100 boards

[Emil Renner Berthing]

The StarFive JH7100 SoC has non-coherent device DMAs, but most drivers
expect to be able to allocate coherent memory for DMA descriptors and
such. However on the JH7100 DDR memory appears twice in the physical
memory map, once cached and once uncached:

  0x00_8000_0000 - 0x08_7fff_ffff : Off chip DDR memory, cached
  0x10_0000_0000 - 0x17_ffff_ffff : Off chip DDR memory, uncached

To use this uncached region we create a global DMA memory pool there and
reserve the corresponding area in the cached region.

However the uncached region is fully above the 32bit address limit, so add
a dma-ranges map so the DMA address used for peripherals is still in the
regular cached region below the limit.
