* Samsung Exynos specific extensions to the Synopsys Designware Mobile
|
||||
Storage Host Controller
|
||||
|
||||
The Synopsys designware mobile storage host controller is used to interface
|
||||
a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
|
||||
differences between the core Synopsys dw mshc controller properties described
|
||||
by synopsys-dw-mshc.txt and the properties used by the Samsung Exynos specific
|
||||
extensions to the Synopsys Designware Mobile Storage Host Controller.
|
||||
|
||||
Required Properties:
|
||||
|
||||
* compatible: should be
|
||||
- "samsung,exynos4210-dw-mshc": for controllers with Samsung Exynos4210
|
||||
specific extensions.
|
||||
- "samsung,exynos4412-dw-mshc": for controllers with Samsung Exynos4412
|
||||
specific extensions.
|
||||
- "samsung,exynos5250-dw-mshc": for controllers with Samsung Exynos5250
|
||||
specific extensions.
|
||||
- "samsung,exynos5420-dw-mshc": for controllers with Samsung Exynos5420
|
||||
specific extensions.
|
||||
- "samsung,exynos7-dw-mshc": for controllers with Samsung Exynos7
|
||||
specific extensions.
|
||||
- "samsung,exynos7-dw-mshc-smu": for controllers with Samsung Exynos7
|
||||
specific extensions having an SMU.
|
||||
- "axis,artpec8-dw-mshc": for controllers with ARTPEC-8 specific
|
||||
extensions.
|
||||
|
||||
* samsung,dw-mshc-ciu-div: Specifies the divider value for the card interface
|
||||
unit (ciu) clock. This property is applicable only for Exynos5 SoC's and
|
||||
ignored for Exynos4 SoC's. The valid range of divider value is 0 to 7.
|
||||
|
||||
* samsung,dw-mshc-sdr-timing: Specifies the value of CIU clock phase shift value
|
||||
in transmit mode and CIU clock phase shift value in receive mode for single
|
||||
data rate mode operation. Refer notes below for the order of the cells and the
|
||||
valid values.
|
||||
|
||||
* samsung,dw-mshc-ddr-timing: Specifies the value of CUI clock phase shift value
|
||||
in transmit mode and CIU clock phase shift value in receive mode for double
|
||||
data rate mode operation. Refer notes below for the order of the cells and the
|
||||
valid values.
|
||||
* samsung,dw-mshc-hs400-timing: Specifies the value of CIU TX and RX clock phase
|
||||
shift value for hs400 mode operation.
|
||||
|
||||
Notes for the sdr-timing and ddr-timing values:
|
||||
|
||||
The order of the cells should be
|
||||
- First Cell: CIU clock phase shift value for tx mode.
|
||||
- Second Cell: CIU clock phase shift value for rx mode.
|
||||
|
||||
Valid values for SDR and DDR CIU clock timing for Exynos5250:
|
||||
- valid value for tx phase shift and rx phase shift is 0 to 7.
|
||||
- when CIU clock divider value is set to 3, all possible 8 phase shift
|
||||
values can be used.
|
||||
- if CIU clock divider value is 0 (that is divide by 1), both tx and rx
|
||||
phase shift clocks should be 0.
|
||||
|
||||
* samsung,read-strobe-delay: RCLK (Data strobe) delay to control HS400 mode
|
||||
(Latency value for delay line in Read path)
|
||||
|
||||
Required properties for a slot (Deprecated - Recommend to use one slot per host):
|
||||
|
||||
* gpios: specifies a list of gpios used for command, clock and data bus. The
|
||||
first gpio is the command line and the second gpio is the clock line. The
|
||||
rest of the gpios (depending on the bus-width property) are the data lines in
|
||||
no particular order. The format of the gpio specifier depends on the gpio
|
||||
controller.
|
||||
(Deprecated - Refer to Documentation/devicetree/bindings/pinctrl/samsung-pinctrl.txt)
|
||||
|
||||
Example:
|
||||
|
||||
The MSHC controller node can be split into two portions, SoC specific and
|
||||
board specific portions as listed below.

MMC/SD/SDIO slot directly connected to a SPI bus
|
||||
|
||||
This file documents differences between the core properties described
|
||||
by mmc.txt and the properties used by the mmc_spi driver.
|
||||
|
||||
Required properties:
|
||||
- spi-max-frequency : maximum frequency for this device (Hz).
|
||||
|
||||
Optional properties:
|
||||
- voltage-ranges : two cells are required, first cell specifies minimum
|
||||
slot voltage (mV), second cell specifies maximum slot voltage (mV).
|
||||
Several ranges could be specified. If not provided, 3.2v..3.4v is assumed.
|
||||
- gpios : may specify GPIOs in this order: Card-Detect GPIO,
|
||||
Write-Protect GPIO. Note that this does not follow the
|
||||
binding from mmc.txt, for historical reasons.
|
||||
|
||||
Example:
|
||||
|
||||
mmc-slot@0 {

* Samsung's SDHCI Controller device tree bindings
|
||||
|
||||
Samsung's SDHCI controller is used as a connectivity interface with external
|
||||
MMC, SD and eMMC storage mediums. This file documents differences between the
|
||||
core mmc properties described by mmc.txt and the properties used by the
|
||||
Samsung implementation of the SDHCI controller.
|
||||
|
||||
Required SoC Specific Properties:
|
||||
- compatible: should be one of the following
|
||||
- "samsung,s3c6410-sdhci": For controllers compatible with s3c6410 sdhci
|
||||
controller.
|
||||
- "samsung,exynos4210-sdhci": For controllers compatible with Exynos4 sdhci
|
||||
controller.
|
||||
|
||||
Required Board Specific Properties:
|
||||
- pinctrl-0: Should specify pin control groups used for this controller.
|
||||
- pinctrl-names: Should contain only one value - "default".
|
||||
|
||||
Example:
|
||||
sdhci@12530000 {
|
||||
compatible = "samsung,exynos4210-sdhci";
|
||||
reg = <0x12530000 0x100>;
|
||||
interrupts = <0 75 0>;
|
||||
bus-width = <4>;
|
||||
cd-gpios = <&gpk2 2 0>;
|
||||
pinctrl-names = "default";
|
||||
pinctrl-0 = <&sd0_clk &sd0_cmd &sd0_bus4>;
|
||||
};
|
||||
|
||||
Note: This example shows both SoC specific and board specific properties
|
||||
in a single device node. The properties can be actually be separated
|
||||
into SoC specific node and board specific node.
