[PATCH 0/4] Add support for Theobroma-Systems Tiger SoM

[Heiko Stuebner]

This adds support for the rk3588-based Tiger system-on-module from
Theobroma Systems and includes support for the combination with
the Haikou-baseboard.

Included is also a fix for the rk3588's i2s nodes to remove a
yet-unsupported devicetree property that slipped in.

[PATCH 1/4] arm64: dts: rockchip: drop rockchip,trcm-sync-tx-only from rk3588 i2s

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

The rockchip,trcm-sync-tx-only property is at this time only documented
for the tdm variant of Rockchip i2s controllers.

While there was a series [0] adding code and binding for the property,
it doesn't seem to have gone forward back in 2021.

So for now fix the devicetree check by removing the property from rk3588
i2s controllers until support for it gets merged.

[PATCH 3/4] arm64: dts: rockchip: add RK3588-Q7 (Tiger) SoM

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

The RK3588-Q7 SoM is a Qseven-compatible (70mm x 70mm, MXM-230
connector) system-on-module from Theobroma Systems, featuring the
Rockchip RK3588.

It provides the following feature set:
 * up to 16GB LPDDR4x
 * on-module eMMC
 * SD card (on a baseboard) via edge connector
 * Gigabit Ethernet with on-module GbE PHY
 * HDMI/eDP
 * MIPI-DSI
 * 4x MIPI-CSI (3x on FPC connectors, 1x over Q7)
 * HDMI input over FPC connector
 * CAN
 * USB
   - 1x USB 3.0 dual-role (direct connection)
   - 2x USB 3.0 host + 1x USB 2.0 host
 * PCIe
   - 1x PCIe 2.1 Gen3, 4 lanes
   - 2xSATA / 2x PCIe 2.1 Gen1, 2 lanes
 * on-module ATtiny816 companion controller, implementing:
   - low-power RTC functionality (ISL1208 emulation)
   - fan controller (AMC6821 emulation)
 * on-module Secure Element with Global Platform 2.2.1 compliant
   JavaCard environment

[PATCH 4/4] arm64: dts: rockchip: add Haikou baseboard with RK3588-Q7 SoM

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

Haikou is a Qseven and μQseven baseboard featuring PCIe, USB3 and a
video connector for a MIPI-DSI/CSI adapter.

This dts is for usage with the RK3588-Q7 SoM Tiger.

It seems like tx-only should be supported if the dai_link has a 
symmetric rate, c.f. 
https://elixir.bootlin.com/linux/latest/source/sound/soc/rockchip/rockchip_i2s.c#L455 
is doing the same as the patch from 3 years ago[1] was trying to do, 
only in the probe.

[1] 
https://patchwork.kernel.org/project/linux-rockchip/patch/1629796734-4243-4-git-send-email-sugar.zhang@rock-chips.com/

Considering that the RK3588 doesn't have RX only support according to 
the documentation of that register....

However, I have no clue how the dai_link would get the symmetrical rate 
set, because the only place I could see it set is in set_link_flags if 
SND_SOC_TPLG_LNK_FLGBIT_SYMMETRIC_RATES if set in the flag mask and the 
flags, but my grep-fu returned nothing setting this flag anywhere... so 
maybe that's just dead code?

In any case, with the current code:

I2S_CKR_TRCM_TXRX is put into I2S_CKR register, regardless of that DT 
property. While the naming seems to suggest TX+RX should be possible, 
its value is 0 (offset 28) and in the TRM it says:

2'b00: Generates LRCK for TX only.

Soooo... we are essentially in tx-only mode today with or without that 
property. Some things to fix later on :)

Which made me look for the same thing for the i2s_tdm driver and the 
same mistake is made, though here there's no support for tx-only or 
rx-only according to the TRM, and it is required to write 0b01 (offset 
28)... which we do by abusing the tx-only DT property which writes 
TRCM_TX whose value is 1 (offset 28). Considering that this is stored in 
clk_trcm member in the struct and that we do checks on that member to 
know in which situation we are (txrx, tx, rx), this seems very incorrect 
to me as we would configure it in the only mode it knows (txrx) but make 
the driver assume tx-only is selected. One more thing to fix later on :)

In any case, this patch is for matching the dt-bindings so there's no 
reason to not merge this, so:

I just realized we have one regulator missing here:

"""
         vcc5v0_otg: vcc5v0-otg-regulator {
                 compatible = "regulator-fixed";
                 enable-active-high;
                 gpio = <&gpio1 RK_PB5 GPIO_ACTIVE_HIGH>;
                 pinctrl-names = "default";
                 pinctrl-0 = <&otg_vbus_drv>;
                 regulator-name = "vcc5v0_otg";
                 regulator-always-on;
         };

&pinctrl {
         usb {
                 otg_vbus_drv: otg-vbus-drv {
                         rockchip,pins =
                           <1 RK_PB5 RK_FUNC_GPIO &pcfg_pull_none>;
                 };
         };
};
"""

This regulator is part of the U11 IC on Haikou and the signal to enable 
it is Q7_USB_OTG_PEN. I guess we can add this once we have SW support in 
the kernel for the USB PHY/controller, so not a blocker.

I think we're supposed to have status = "okay" as last property before 
the children nodes.

My bot found new DT warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


New warnings running 'make CHECK_DTBS=y rockchip/rk3588-tiger-haikou.dtb' for 20240227164659.705271-1-heiko@sntech.de:

arch/arm64/boot/dts/rockchip/rk3588-tiger-haikou.dtb: syscon@fd5a8000: 'clocks' is a required property
	from schema $id: http://devicetree.org/schemas/soc/rockchip/grf.yaml#

for the record, this is fixed by
https://lore.kernel.org/linux-rockchip/20240227210521.724754-1-heiko@sntech.de

which I applied earlier today.
