So that's enum with previous entry... What's with Allwinner patches
recently that they do not use that syntax?

Heh, no it isn't only that. You actually broke other users! And you
received that comment already at v3 which you completely ignored.
This looks like introducing real bugs.

The current sd_database does not contain an entry for ATP (Manufacturer ID 0x09).
Add it so that lsmmc can correctly identify ATP SD cards.

Hi Jernej,

Agreed on both points. I'll move the UART0 pin definition into the main
A733 DTSI for the next revision, following the other Allwinner SoCs.
I will also hold off on sending a v2 until the A733 clock prerequisites
are in a better state, unless maintainers prefer a different ordering.
For now I'll keep this series as a checkpoint and continue tracking/testing
the RTC, clock and pinctrl prerequisite work.
Best regards,
Enzo

Besides sashiko bot comments, these pins should go to main A733 DTSI,
like it's done for other SoCs.
In any case, it's a bit early for DT. At least clocks should land before.

* [PATCH 0/4] arm64: dts: allwinner: add A733/Cubie A7S DTS support
From: Enzo Adriano via B4 Relay @ 2026-06-13 9:42 UTC (permalink / raw)
To: Rob Herring, Krzysztof Kozlowski, Conor Dooley, Chen-Yu Tsai,
Jernej Skrabec, Samuel Holland, Maxime Ripard, Ulf Hansson
Cc: devicetree, linux-arm-kernel, linux-sunxi, linux-kernel,
linux-mmc, Enzo Adriano
This series adds initial devicetree support for the Allwinner A733 SoC and
Radxa Cubie A7S board.
It includes the Radxa Cubie A7S board compatible, the A733 MMC compatible,
an initial A733 SoC DTSI with CPUs, timer, GICv3, RTC oscillator provider,
CCU/R-CCU, pinctrl, UART0, and SDMMC0, and a board DTS enabling UART0 console
and SD card boot storage.
This series intentionally does not carry local CCU/PRCM or pinctrl driver
patches. Those areas overlap active A733 RFC work and remain external
prerequisites unless maintainers ask for a different plan. The A733 CCU RFC
also depends on the A733 RTC series.
Ethernet, VPU/Cedrus, display, Wi-Fi, Bluetooth, USB-C, PCIe, and other board
peripherals are intentionally out of scope. Vendor U-Boot workarounds used for
local proof collection are not encoded in these device trees.
Cubie A7S runtime proof has shown the v4 Image and DTB loading, Linux
7.1.0-rc6-gabc8d07b0a63, Radxa Cubie A7S machine model, 8 CPUs, GICv3
redistributors, A733 pinctrl/UART0, SDMMC0 enumeration, mmcblk0 partition
discovery, and a read-only mmcblk0p3 root mount via the corrected PARTUUID
path.

* [PATCH v4 2/2] dt-bindings: mmc: st,sdhci: Convert to DT schema

To: Ulf Hansson, Rob Herring, Krzysztof Kozlowski, Conor Dooley,
Peter Griffin, Patrice Chotard

In-Reply-To: <20260613-st-mmc-v4-0-b3c385617c16@gmail.com>
Convert STMicroelectronics sdhci-st MMC/SD controller binding to
DT schema.
The 'icn' clock and 'top-mmc-delay' register region are optional in
the text binding and remain so in the YAML schema. minItems: 1 is
set on clock-names and reg-names to match the flexibility of their
paired clocks and reg properties, preserving compatibility with
existing in-tree DTS nodes that provide only a single clock or
register entry.

-* STMicroelectronics sdhci-st MMC/SD controller
-
-This file documents the differences between the core properties in
-Documentation/devicetree/bindings/mmc/mmc.txt and the properties
-used by the sdhci-st driver.
-
-Required properties:
-- compatible: Must be "st,sdhci" and it can be compatible to "st,sdhci-stih407"
- to set the internal glue logic used for configuring the MMC
- subsystem (mmcss) inside the FlashSS (available in STiH407 SoC
- family).
-
-- clock-names: Should be "mmc" and "icn". (NB: The latter is not compulsory)
- See: Documentation/devicetree/bindings/resource-names.txt
-- clocks: Phandle to the clock.
- See: Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-- interrupts: One mmc interrupt should be described here.
-- interrupt-names: Should be "mmcirq".
-
-- pinctrl-names: A pinctrl state names "default" must be defined.
-- pinctrl-0: Phandle referencing pin configuration of the sd/emmc controller.
- See: Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
-
-- reg: This must provide the host controller base address and it can also
- contain the FlashSS Top register for TX/RX delay used by the driver
- to configure DLL inside the flashSS, if so reg-names must also be
- specified.
-
-Optional properties:
-- reg-names: Should be "mmc" and "top-mmc-delay". "top-mmc-delay" is optional
- for eMMC on stih407 family silicon to configure DLL inside FlashSS.
-
-- non-removable: Non-removable slot. Also used for configuring mmcss in STiH407 SoC
- family.
- See: Documentation/devicetree/bindings/mmc/mmc.txt.
-
-- bus-width: Number of data lines.
- See: Documentation/devicetree/bindings/mmc/mmc.txt.
-
-- max-frequency: Can be 200MHz, 100MHz or 50MHz (default) and used for
- configuring the CCONFIG3 in the mmcss.
- See: Documentation/devicetree/bindings/mmc/mmc.txt.
-
-- resets: Phandle and reset specifier pair to softreset line of HC IP.
- See: Documentation/devicetree/bindings/reset/reset.txt
-
-- vqmmc-supply: Phandle to the regulator dt node, mentioned as the vcc/vdd
- supply in eMMC/SD specs.
-
-- sd-uhs-sdr50: To enable the SDR50 in the mmcss.
- See: Documentation/devicetree/bindings/mmc/mmc.txt.
-
-- sd-uhs-sdr104: To enable the SDR104 in the mmcss.
- See: Documentation/devicetree/bindings/mmc/mmc.txt.
-

* [PATCH v4 0/2] dt-bindings: mmc: st,sdhci: convert STMicroelectronics SDHCI-ST MMC/SD Controller controller binding to YAML
From: Charan Pedumuru @ 2026-06-13 9:39 UTC (permalink / raw)
To: Ulf Hansson, Rob Herring, Krzysztof Kozlowski, Conor Dooley,

Cc: linux-mmc, devicetree, linux-kernel, linux-arm-kernel,
Charan Pedumuru
This patch series converts the legacy text-based Device Tree binding for
STMicroelectronics SDHCI-ST MMC/SD controller to DT schema (YAML) format.
Note:
The patch "dt-bindings: mmc: st,sdhci: convert to DT schema"
depends on the patch "arm: dts: st: align node patterns with established
convention". If the DT schema patch is applied before the DTS
cleanup patch, `dtbs_check` will fail due to the presence of the removed
properties in the existing DTS.
Signed-off-by: Charan Pedumuru <charan.pedumuru@gmail.com>
---
Changes in v4:
- st,sdhci: Add minItems: 1 to clock-names and reg-names to allow single-entry
configurations, fixing dtbs_check failures on nodes that omit the
optional 'icn' clock or 'top-mmc-delay' register region.
- st,sdhci: Modify the commit message to explain the changes.
- Link to v3: https://patch.msgid.link/20260508-st-mmc-v3-0-81c329ed28e8@gmail.com
Changes in v3:
- st,sdhci: Edit description of reg property. Modify reg-names. Add
"minItems" for clocks and clock-names properties.
- Modify the commit message to match with the updated changes.
- Link to v2: https://patch.msgid.link/20260503-st-mmc-v2-0-11ae3216d2ce@gmail.com
Changes in v2:
- Fix node name in DTS for the MMC to match with the estableshed convention.
- st,sdhci: drop unnecessary properties, modify "reg", "reg-names" and
"clock-names" properties, include an allOf with $ref to mmc-controller.
- Link to v1: https://patch.msgid.link/20260409-st-mmc-v1-1-4c54321c3535@gmail.com

I understand that with this series you are targeting the m68K tree, am I
correct?
A possibly better option would be, after that the pre-req patches land
into Linus's tree, to share an immutable branch for this series, so that
both m68k and net-next could pull it.

Kuleep highlighted a concern with the usage of "Link:" tag. The link i
provided guides on posting patches to upstream linux. Wanted to highlight
what i folloed and I did not find any specific comment/line in the guide
which prohibits author to use "Link:" tag in trailer section. If there
are guidelines otherwise please let me know and i will correct and post

Add device trees for the Shikra EVK platform, which combines each
of Shikra SoM variant with a common carrier board.
Three EVK boards are introduced:
- shikra-cqm-evk.dts: pairs with CQ2390M SoM (retail, with modem)
- shikra-cqs-evk.dts: pairs with CQ2390S SoM (retail, without modem)
- shikra-iqs-evk.dts: pairs with IQ2390S SoM (industrial, without modem)
Also add shikra-evk.dtsi, it represents the common carrier-board and
daughter-card configuration shared across all Shikra EVK variants.

System-on-Module, an industrial compute module integrating the Shikra
SoC and PMIC for industrial IoT applications, designed to mount on
carrier boards.
- shikra-iqs-som.dtsi: Industrial SoM without modem (PM8150 PMIC)
The DTSI includes the common shikra.dtsi and adds PM8150 PMIC regulator
definitions specific to this variant.

In-Reply-To: <20260612-shikra-dt-v6-0-6b6cb58db477@oss.qualcomm.com>
Add device tree include for the CQ2390M variant of the Shikra
System-on-Module, a compact compute module integrating the Shikra SoC
and PMIC for IoT applications, designed to mount on carrier boards.
- shikra-cqm-som.dtsi: Retail SoM with modem (PM4125 and PM8005 PMIC)
The DTSI includes the common shikra.dtsi, adds PM4125 and PM8005 PMIC
peripheral definitions specific to this variant. Since PM8005 regulators
are controlled by rpmpd, so disabling the pm8005 regulators.

In-Reply-To: <20260612-shikra-dt-v6-0-6b6cb58db477@oss.qualcomm.com>
Shikra is a Qualcomm IoT SoC available in a System-on-Module (SoM)
form factor. The SoM integrates the Shikra SoC, PMICs, and essential
passives, and is designed to be mounted on carrier boards.
Three eSoM variant are introduced:
- CQM: retail variant with integrated modem (PM4125 and PM8005 PMIC)
- CQS: retail variant without modem (PM4125 and PM8005 PMIC)
- IQS: industrial-grade variant without modem (PM8150 PMIC)
Each SoM variant pairs with a common EVK carrier board provides debug
UART, USB, and other peripheral interfaces.
Add compatible strings for the CQ2390M, CQ2390S, IQ2390S SoM variant and
its corresponding EVK boards.

Add initial device tree support for the Qualcomm Shikra SoC.
Shikra ships in a SoM form factor; this series covers the CQ2390M,
CQ2390S and IQ2390S SoM variants and their EVK boards.
The series adds:
- dt-bindings for the Shikra SoC, CQ2390M/CQ2390S/IQ2390S EVK boards
- SoC base DTSI
- CQ2390M SoM DTSI with PM4125 and PM8005 PMIC regulator definitions
- IQ2390S SoM DTSI with PM8150 PMIC regulator definitions
- EVK DTS files enabling UART and eMMC on the carrier board
Note: USB support is intentionally dropped from this series. It will be
sent separately once the USB driver changes for Shikra are concluded.
