[PATCH v3 00/15] Canaan devicetree fixes

[PATCH v3 00/15] 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 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 v3 01/15] 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 v3 01/15] 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 v3 03/15] ASoC: dt-bindings: convert designware-i2s to dt-schema

[Conor Dooley]

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

Convert the Synopsys DesignWare I2S controller binding to dt-schema.
There was no listed maintainer but Jose Abreu was the last editor of the
txt binding so add him as maintainer.

-DesignWare I2S controller
-
-Required properties:
- - compatible : Must be "snps,designware-i2s"
- - reg : Must contain the I2S core's registers location and length
- - clocks : Pairs of phandle and specifier referencing the controller's
-   clocks. The controller expects one clock: the clock used as the sampling
-   rate reference clock sample.
- - clock-names : "i2sclk" for the sample rate reference clock.
- - dmas: Pairs of phandle and specifier for the DMA channels that are used by
-   the core. The core expects one or two dma channels: one for transmit and
-   one for receive.
- - dma-names : "tx" for the transmit channel, "rx" for the receive channel.
-
-Optional properties:
- - interrupts: The interrupt line number for the I2S controller. Add this
-   parameter if the I2S controller that you are using does not support DMA.
-
-For more details on the 'dma', 'dma-names', 'clock' and 'clock-names'
-properties please check:

[PATCH v3 04/15] spi: dt-bindings: dw-apb-ssi: update spi-{r,t}x-bus-width

[Conor Dooley]

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

Most users of dw-apb-ssi use spi-{r,t}x-bus-width of 1, however the
Canaan k210 is wired up for a width of 4.
Quoting Serge:
The modern DW APB SSI controllers of v.4.* and newer also support the
enhanced SPI Modes too (Dual, Quad and Octal). Since the IP-core
version is auto-detected at run-time there is no way to create a
DT-schema correctly constraining the Rx/Tx SPI bus widths.
/endquote

As such, drop the restriction on only supporting a bus width of 1.

[PATCH v3 05/15] 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.

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

[PATCH v3 07/15] riscv: dts: canaan: fix the k210's memory node

[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. The regs property does not fit in
either node, so is replaced by comments.

[PATCH v3 08/15] 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 v3 09/15] riscv: dts: canaan: fix mmc node names

[Conor Dooley]

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

The newly-converted-to-dt-schema binding expects the mmc node name to be
'^mmc(@.*)?$' so align the devicetree with the schema.

[PATCH v3 09/15] riscv: dts: canaan: fix mmc node names

[Conor Dooley]

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

The newly-converted-to-dt-schema binding expects the mmc node name to be
'^mmc(@.*)?$' so align the devicetree with the schema.

[PATCH v3 10/15] 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 v3 11/15] 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 v3 12/15] 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.

[PATCH v3 13/15] riscv: dts: canaan: fix bus {ranges,reg} warnings

[Conor Dooley]

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

The k210 devicetrees warn about missing/empty reg and/or ranges
properties:
arch/riscv/boot/dts/canaan/k210.dtsi:408.22-460.5: Warning (unit_address_vs_reg): /soc/bus@52000000: node has a unit name, but no reg or ranges property
arch/riscv/boot/dts/canaan/k210.dtsi:352.22-406.5: Warning (simple_bus_reg): /soc/bus@50400000: missing or empty reg/ranges property

Add reg and ranges properties that naively cap the buses after the
allocation of their last devices.

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

I first tried to apply your series on top of next-20220630,
but was greeted by a bunch of different warnings on boot,
including endless RCU stall warnings.
However, even when booting next-20220630 without your patches,
I got the same warnings and RCU stall.

So I tested your series on top of v5.19-rc4 +
commit 0397d50f4cad ("spi: dt-bindings: Move 'rx-sample-delay-ns' to
spi-peripheral-props.yaml") cherry-picked,
(in order to avoid conflicts when applying your series,)
and the board was working as intended, no warnings or RCU stalls.

I tried both booting both via u-boot (with u-boots DTB)
and booting the kernel (with an initrd) directly.
I could successfully read data from the MMC in both cases.

This looks wrong.

The property is called "reg" not "regs".

And I don't think that you should provide "reg" at all,
simply supplying "ranges" should be sufficient, no?

FYI, I see rcu warnings on boot on my dual-socket 8-cores Xeon system, but
the same kernel does not have the rcu warnings with an AMD Epyc single
socket 16-cores box.

Just to note. IMO the DW APB Timer driver has been incorrectly
designed in the first place. The dts-node is supposed to describe the
whole IP-core timers set as the original Canaan k210 DT-file expected,
since there are common CSRs in the registers range, which currently
get to be unreachable. But since the DT-bindings has already been
defined that way in the framework of DW APB Timer driver alas there
is nothing we can do to fix it.

whole IP-core timers set as the original Canaan k210 DT-file expected,
since there are common CSRs in the registers range, which currently
get to be unreachable. But since the DT-bindings has already been
defined that way in the framework of DW APB Timer driver alas there
is nothing we can do to fix it.

I will change it to:
  interrupts:
    description: |
      If the IP-core synthesis parameter DMAX_INTR_IO_TYPE is set to 1, this
      will be per-channel interrupts. Otherwise, this is a single combined IRQ
      for all channels.
    minItems: 1
    maxItems: 8

How's that sound?

[04/15] spi: dt-bindings: dw-apb-ssi: update spi-{r,t}x-bus-width
        commit: 8b037cabc4966b010c44a76e05a43d276318bc49

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.
