[PATCH v4 00/14] Canaan devicetree fixes

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

Hey all,
This series should rid us of dtbs_check errors for the RISC-V Canaan k210
based boards. To make keeping it that way a little easier, I changed the
Canaan devicetree Makefile so that it would build all of the devicetrees
in the directory if SOC_CANAAN.

I *DO NOT* have any Canaan hardware so I have not tested any of this in
action. Since I sent v1, I tried to buy some since it's cheap - but could
out of the limited stockists none seemed to want to deliver to Ireland :(
I based the series on next-20220617.

Thanks,
Conor.

Changes since v3:
- dts: drop the bogus "regs" property pointed out by Niklas
- dma/timer: add Serge's reviews (and expand on the dma interrupt
  description)
- dts: add Niklas' T-b where I felt it was suitable. lmk if you think it
  applies more broadly
- spi: drop the applied spi dt-binding change. Thanks Mark.

Changes since v2:
- i2s: added clocks maxItems
- dma: unconditionally extended the interrupts & dropped canaan
  compatible
- timer: as per Sergey, split the timer dts nodes in 2 & drop the
  binding patch
- ili9341: add a canaan specific compatible to the binding and dts

Changes since v1:
- I added a new dt node & compatible for the SRAM memory controller due
  Damien's wish to preserve the inter-op with U-Boot.
- The dw-apb-ssi binding now uses the default rx/tx widths
- A new patch fixes bus {ranges,reg} warnings
- Rearranged the patches in a slightly more logical order

[PATCH v4 01/14] dt-bindings: display: convert ilitek,ili9341.txt to dt-schema

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

A dt-schema binding for the Ilitek ili9341 was created as
panel/ilitek,ili9341.yaml but the txt binding was ignored in the
process. Move the remaining items in the txt binding to the yaml one &
delete it.

The example in the txt binding has a spi-max-frequency which disagrees
with the yaml replacement (and its own documentation) so change that to
conform with the binding. There are no users in tree of the Adafruit
yx240qv29 to check against.

[PATCH v4 01/14] dt-bindings: display: convert ilitek, ili9341.txt to dt-schema

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

A dt-schema binding for the Ilitek ili9341 was created as
panel/ilitek,ili9341.yaml but the txt binding was ignored in the
process. Move the remaining items in the txt binding to the yaml one &
delete it.

The example in the txt binding has a spi-max-frequency which disagrees
with the yaml replacement (and its own documentation) so change that to
conform with the binding. There are no users in tree of the Adafruit
yx240qv29 to check against.

[PATCH v4 04/14] dt-bindings: dma: dw-axi-dmac: extend the number of interrupts

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

The Canaan k210 apparently has a Sysnopsys Designware AXI DMA
controller, but according to the documentation & devicetree it has 6
interrupts rather than the standard one. Support the 6 interrupt
configuration by unconditionally extending the binding to a maximum of
8 per-channel interrupts thereby matching the number of possible
channels.

From: Conor Dooley <conor.dooley@microchip.com>

The k210 U-Boot port has been using the clocks defined in the
devicetree to bring up the board's SRAM, but this violates the
dt-schema. As such, move the clocks to a dedicated node with
the same compatible string & document it.

[PATCH v4 05/14] dt-bindings: memory-controllers: add canaan k210 sram controller

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

The k210 U-Boot port has been using the clocks defined in the
devicetree to bring up the board's SRAM, but this violates the
dt-schema. As such, move the clocks to a dedicated node with
the same compatible string & document it.

The k210 U-Boot port has been using the clocks defined in the

[PATCH v4 07/14] riscv: dts: canaan: fix the k210's timer nodes

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

The timers on the k210 have non standard interrupt configurations,
which leads to dtbs_check warnings:

k210_generic.dtb: timer@502d0000: interrupts: [[14], [15]] is too long
From schema: Documentation/devicetree/bindings/timer/snps,dw-apb-timer.yaml

Split the timer nodes in two, so that the second timer in the IP block
can actually be accessed & in the process solve the dtbs_check warning.

[PATCH v4 09/14] riscv: dts: canaan: fix kd233 display spi frequency

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

The binding for the ili9341 specifies a const spi-max-frequency of 10
MHz but the kd233 devicetree entry has it listed at 15 Mhz.
Align the devicetree with the value in the binding.

[PATCH v4 10/14] riscv: dts: canaan: use custom compatible for k210 i2s

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

The devicetrees using the Canaan k210 all have a sound-dai-cells value
of 1, whereas the standard binding example for the DesignWare i2s and
other use cases suggest 0. Use a k210 specific compatible which
supports this difference.

[PATCH v4 11/14] riscv: dts: canaan: remove spi-max-frequency from controllers

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

spi-max-frequency is a device, not a controller  property and should be
removed.

From: Conor Dooley <conor.dooley@microchip.com>

Testing & checking the Canaan devicetrees is inconvenient as only the

Change the Makefile so that all devicetrees are built by default if
SOC_CANAAN but only the one specified by SOC_CANAAN_K210_DTB_BUILTIN
gets built as an object.

[PATCH v4 14/14] riscv: dts: canaan: build all devicetress if SOC_CANAAN

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

Testing & checking the Canaan devicetrees is inconvenient as only the
devicetree corresponding to SOC_CANAAN_K210_DTB_BUILTIN will be built.
Change the Makefile so that all devicetrees are built by default if
SOC_CANAAN but only the one specified by SOC_CANAAN_K210_DTB_BUILTIN
gets built as an object.

[03/14] ASoC: dt-bindings: convert designware-i2s to dt-schema
        commit: bc4c9d85179ca90679c8bb046cf7aad16fb88076

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Yeah, I was a bit gung-ho & sent before v4 with other fixes prior
to his review of v3. I didn't intentionally ignore him :)

I'll resend later tonight.

Yeah, I was a bit gung-ho & sent before v4 with other fixes prior
to his review of v3. I didn't intentionally ignore him :)

I'll resend later tonight.

How the OS going to do that? You don't have any way defined to access
