dt-bindings: mmc: convert arasan sdhci bindings to yaml
Convert arasan,sdhci.txt file to yaml. The new file arasan,sdhci.yaml will inherit properties from mmc-controller.yaml. 'sdhci' is no longer a valid name for node and should be changed to 'mmc'.

Device Tree Bindings for the Arasan SDHCI Controller
|
|
||||||
|
|
||||||
The bindings follow the mmc[1], clock[2], interrupt[3] and phy[4] bindings.
|
|
||||||
Only deviations are documented here.

|
||||||

||||||
[1] Documentation/devicetree/bindings/mmc/mmc.txt
|
|
||||||
[2] Documentation/devicetree/bindings/clock/clock-bindings.txt

[4] Documentation/devicetree/bindings/phy/phy-bindings.txt
|
|
||||||
|
|
||||||
Required Properties:
|
|
||||||
- compatible: Compatibility string. One of:
|
|
||||||
- "arasan,sdhci-8.9a": generic Arasan SDHCI 8.9a PHY
|
|
||||||
- "arasan,sdhci-4.9a": generic Arasan SDHCI 4.9a PHY
|
|
||||||
- "arasan,sdhci-5.1": generic Arasan SDHCI 5.1 PHY

|
||||||
- "rockchip,rk3399-sdhci-5.1", "arasan,sdhci-5.1": rk3399 eMMC PHY
|
|
||||||
For this device it is strongly suggested to include arasan,soc-ctl-syscon.
|
|
||||||
- "xlnx,zynqmp-8.9a": ZynqMP SDHCI 8.9a PHY
|
|
||||||
For this device it is strongly suggested to include clock-output-names and
|
|
||||||
#clock-cells.
|
|
||||||
- "xlnx,versal-8.9a": Versal SDHCI 8.9a PHY
|
|
||||||
For this device it is strongly suggested to include clock-output-names and
|
|
||||||
#clock-cells.
|
|
||||||
- "ti,am654-sdhci-5.1", "arasan,sdhci-5.1": TI AM654 MMC PHY
|
|
||||||
Note: This binding has been deprecated and moved to [5].
|
|
||||||
- "intel,lgm-sdhci-5.1-emmc", "arasan,sdhci-5.1": Intel LGM eMMC PHY
|
|
||||||

|
|
||||||
- "intel,keembay-sdhci-5.1-emmc", "arasan,sdhci-5.1": Intel Keem Bay eMMC
|
|
||||||
For this device it is strongly suggested to include arasan,soc-ctl-syscon.
|
|
||||||
- "intel,keembay-sdhci-5.1-sd": Intel Keem Bay SD controller
|
|
||||||
For this device it is strongly suggested to include arasan,soc-ctl-syscon.
|
|
||||||
- "intel,keembay-sdhci-5.1-sdio": Intel Keem Bay SDIO controller
|
|
||||||
For this device it is strongly suggested to include arasan,soc-ctl-syscon.

|
||||||
|
|
||||||
[5] Documentation/devicetree/bindings/mmc/sdhci-am654.txt
|
|
||||||
|
|
||||||
- reg: From mmc bindings: Register location and length.
|
|
||||||
- clocks: From clock bindings: Handles to clock inputs.
|
|
||||||
- clock-names: From clock bindings: Tuple including "clk_xin" and "clk_ahb"
|
|
||||||
- interrupts: Interrupt specifier
|
|
||||||
|
|
||||||
Required Properties for "arasan,sdhci-5.1":
|
|
||||||
- phys: From PHY bindings: Phandle for the Generic PHY for arasan.
|
|
||||||
- phy-names: MUST be "phy_arasan".
|
|
||||||
|
|
||||||
Optional Properties:
|
|
||||||
- arasan,soc-ctl-syscon: A phandle to a syscon device (see ../mfd/syscon.txt)
|
|
||||||
used to access core corecfg registers. Offsets of registers in this
|
|
||||||
syscon are determined based on the main compatible string for the device.
|
|
||||||
- clock-output-names: If specified, this will be the name of the card clock
|
|
||||||
which will be exposed by this device. Required if #clock-cells is
|
|
||||||
specified.
|
|
||||||
- #clock-cells: If specified this should be the value <0> or <1>. With this
|
|
||||||
property in place we will export one or two clocks representing the Card
|
|
||||||
Clock. These clocks are expected to be consumed by our PHY.
|
|
||||||
- xlnx,fails-without-test-cd: when present, the controller doesn't work when
|
|
||||||
the CD line is not connected properly, and the line is not connected
|
|
||||||
properly. Test mode can be used to force the controller to function.
|
|
||||||
- xlnx,int-clock-stable-broken: when present, the controller always reports
|
|
||||||
that the internal clock is stable even when it is not.
|
|
||||||
|
|
||||||
- xlnx,mio-bank: When specified, this will indicate the MIO bank number in
|
|
||||||
which the command and data lines are configured. If not specified, driver
|
|
||||||
will assume this as 0.
