[PATCH v3 0/9] mips: Support for RTL9302C

[PATCH v3 0/9] mips: Support for RTL9302C

[Chris Packham]

This series adds basic support for the RTL9302C reference board. Currently the
focus is on the CPU block stuff. I hope to get around to the DSA switch driver
eventually but this is a small start that lets me boot a mainline kernel on the
board I have. I initialiy started with code from openwrt but have paired it
down to just the clocksource driver and devicetree.

The first two patches in this series are fixing some complaints from make
dtbs_check for some existing realtek dts files. They can be applied on their
own if desired.

Chris Packham (9):
  mips: dts: realtek: use "serial" instead of "uart" in node name
  mips: dts: realtek: add device_type property to cpu node
  dt-bindings: vendor-prefixes: Add Cameo Communications
  dt-bindings: mips: realtek: Add rtl930x-soc compatible
  dt-bindings: timer: Add schema for realtek,otto-timer
  dt-bindings: interrupt-controller: realtek,rtl-intc: Add rtl9300-intc
  clocksource: realtek: Add timer driver for rtl-otto platforms
  mips: generic: add fdt fixup for Realtek reference board
  mips: dts: realtek: Add RTL9302C board

[PATCH v3 1/9] mips: dts: realtek: use "serial" instead of "uart" in node name

[Chris Packham]

Update the node name for the UARTs to resolve the following dtbs_check
complaints:

  uart@2000: $nodename:0: 'uart@2000' does not match '^serial(@.*)?$'
  uart@2100: $nodename:0: 'uart@2100' does not match '^serial(@.*)?$'

[PATCH v3 2/9] mips: dts: realtek: add device_type property to cpu node

[Chris Packham]

Add device_type = "cpu" to the cpu node for the rtl838x SoC. This
resolves the following dtbs_check complaint:

 cpus: cpu@0: 'cache-level' is a required property

[PATCH v3 4/9] dt-bindings: mips: realtek: Add rtl930x-soc compatible

[Chris Packham]

Add the rtl9302 SoC and the Cameo RTL9302C_2xRTL8224_2XGE reference
board to the list of Realtek compatible strings.

Notes:
    Changes in v3:
    - Use full board name
    - I've decided to stick with rtl9302-soc to disambiguate it from what I
      eventually plan to add as rtl9302-switch which is in the same package
      but are separate dies.
    Changes in v2:
    - Use specific compatible for rtl9302-soc
    - Fix to allow correct board, soc compatible

[PATCH v3 6/9] dt-bindings: interrupt-controller: realtek,rtl-intc: Add rtl9300-intc

[Chris Packham]

Add a compatible string for the interrupt controller found on the
rtl930x SoCs. The interrupt controller has registers for VPE1 so these
are added as a second reg cell.

Notes:
    Changes in v3:
    - Use items to describe the regs property
    Changes in v2:
    - Set reg:maxItems to 2 to allow for VPE1 registers on the rtl9300. Add
      a condition to enforce the old limit on other SoCs.
    - Connor and Krzysztof offered acks on v1 but I think the changes here
      are big enough to void those.

[PATCH v3 7/9] clocksource: realtek: Add timer driver for rtl-otto platforms

[Chris Packham]

The timer/counter block on the Realtek SoCs provides up to 5 timers. It
also includes a watchdog timer but this isn't being used currently (it
will be added as a separate wdt driver).

One timer will be used per CPU as a local clock event generator. An
additional timer will be used as an overal stable clocksource.

[PATCH v3 8/9] mips: generic: add fdt fixup for Realtek reference board

[Chris Packham]

The bootloader used on the Realtek RTL9302C boards is an ancient vendor
fork of U-Boot that doesn't understand device trees. So to run a modern
kernel it is necessary use one of the APPENDED_DTB options.

When appending the DTB the inintrd information, if present, needs to be
inserted into the /chosen device tree node. The bootloader provides the
initrd start/size via the firmware environment. Add a fdt fixup that
will update the device tree with the initrd information.

[PATCH v3 9/9] mips: dts: realtek: Add RTL9302C board

[Chris Packham]

Add support for the RTL9302 SoC and the RTL9302C_2xRTL8224_2XGE
reference board.

The RTL930x family of SoCs are Realtek switches with an embedded MIPS
core (800MHz 34Kc). Most of the peripherals are similar to the RTL838x
SoC and can make use of many existing drivers.

Add in full DSA switch support is still a work in progress.

Notes:
    Changes in v3:
    - Use full board name
    Changes in v2:
    - Use specific compatibles instead of rtl930x
    - Remove unnecessary irq flags (interrupt controller is one-cell)
    - Remove earlycon
    - Name clocks as recommended in dt schema

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Is this correct? Sometimes it makes sense to use DIV_ROUND_CLOSEST, but

Your emails are being sent as quoted-printable encoding which is
generally preferred to be avoided on maillists (as is base64).
git-send-email should normally use 8-bit encoding, but the man page
indicates QP may be used if there are carriage returns (there

Is this really specific to this board/soc? I think there are lots of
MIPS boards in this state. The code to handle all the possible
combinations of bootloader handoff information and sources of DTB is
quite the mess. Just for DTB source you have bootloader DTB, appended
DTB, or built-in DTB (and there's even logic if you have multiple of
those). Contrast that to arm32 ('the zoo"), where you have 2 choices:
bootloader DTB or appended DTB with legacy bootloader parameters
transferred to DTB. All the uglyness is contained and the kernel boot
deals with 1 possibility. </rant>

Instead of providing a (SoC dependent) number of reg and interrupt items, can't we just
provide one reg+interrupt per timer and instantiate one block for however many timers the
SoC has?

So this would become:
	timer@3200 {
		compatible = ...
		reg = <0x3200 0x10>;
		interrupt-parent = <&intc>;
		interrupts = <7>;
		...
	};
	timer@3210 {
		compatible = ...
		reg = <0x3210 0x10>;
		interrupt-parent = <&intc>;
		interrupts = <8>;
		...
	};
	...

More verbose, but it also makes the binding a bit simpler. The driver can then still do
whatever it wants with all the timers that are registered, although some more resource
locking might be required.

Sander

Do you mean the watchdog timer supported by drivers/watchdog/realtek_otto_wdt.c? Or are
you referring to another watchdog timer?

For reference, I submitted a driver for the same hardware back in 2022, but didn't manage

In the original review of this code, I had some doubts about the use of IRQF_PERCPU. Maybe
the people in Cc can shed some light on this.

If I understand correctly, the SoC interrupts these timers use are not per-cpu interrupts.
(For comparison, AFAICT the MIPS CPU interrupts are)

If the use of IRQF_PERCPU is appropriate, I wonder if the driver should also use
CLOCK_EVT_FEAT_PERCPU.

Hmm I really did test this. Even now running

`make ARCH=mips O=build_mips 
DT_SCHEMA_FILES=realtek,rtl-intc.yaml:realtek-rtl.yaml:realtek,otto-timer.yaml 
clean dt_binding_check` doesn't seem to yield any complaints. Am I 
testing this properly?

Based on my sample size of 1 I can't say. I thought this was a quirk of 
the realtek SDK version of U-Boot because it's based on something old 
and dt unaware. I did think about putting this code in a more generic 
place but in the end I went with something less invasive figuring it 
could be expanded on later if needed.

> I think there are lots of MIPS boards in this state.

If anyone can confirm that I'd be happy to make the workaround kick in 
if the fw_env has an initrd_start in it. I'm not sure if there is any 
risk in that approach. I don't know how other mips boards are currently 
booting using the generic board support.

Copy and paste from the existing arch/mips/generic/board-*.c. I'm fine

Hmm here's the output from when I sent this series.

Subject: [PATCH v3 0/9] mips: Support for RTL9302C
Date: Thu, 27 Jun 2024 16:33:08 +1200
Message-ID: <20240627043317.3751996-1-chris.packham@alliedtelesis.co.nz>

All the patches are also 8bit. So I think git chose the right thing.

I do keep needing to convince Thunderbird to send my replies as plain 
text. Occasionally I forget and vger complains at me.

Yes realtek_otto_wdt.c. I thought that was only on openwrt but looks 
like you've already landed that one. I'll reword my message to reflect that.

OK thanks for the link. I'll try and make sure I'm not rehashing things 
that have already been discussed.

I'm not exactly sure either and I've only got the single core RTL9302 to 
test with so if there were some difference I may not notice. Eventually 
we're planning a RTL931x based board so that may be something I can 
check then.

I kind of prefer the single entry for the whole TCU. If we were to fold 
the watchdog into this then we could have a single larger range that 
covered all the timers similar to the ingenic,tcu. But that would 
technically be a breaking change at this point.

Looks like there is a difference between 
`DT_SCHEMA_FILES=realtek,rtl-intc.yaml` and 
`DT_SCHEMA_FILES=realtek,rtl-intc.yaml:realtek-rtl.yaml:realtek,otto-timer.yaml`.

I did a bit of digging. My replies are indeed being sent as 
quoted-printable and get base64 encoded by the time they hit lore e.g. 
https://lore.kernel.org/all/68a574c0-2775-4275-b590-b7f362ae3885@alliedtelesis.co.nz/raw 
(not sure where that's happening).

There are some suggestions for older versions of Thunderbird but none of 
the options exist for me. It seems I'm not the only one with an issue 
https://www.reddit.com/r/Thunderbird/comments/18drd4p/how_to_set_contenttransferencoding/

I'll keep looking but if anyone knows how to tame Thunderbird that'd be 
a great help.

It's OK for me because the Lexra bus clock is 175mhz so plain division 
works fine. The docs do say something about a configurable divisor but 
the range seems fairly limited so I don't think there's a specific need 
to use DIV_ROUND_CLOSEST.
