-* Qualcomm SDHCI controller (sdhci-msm)
-
-This file documents differences between the core properties in mmc.txt
-and the properties used by the sdhci-msm driver.
-
-Required properties:
-- compatible: Should contain a SoC-specific string and a IP version string:
- version strings:
- "qcom,sdhci-msm-v4" for sdcc versions less than 5.0
- "qcom,sdhci-msm-v5" for sdcc version 5.0
- For SDCC version 5.0.0, MCI registers are removed from SDCC
- interface and some registers are moved to HC. New compatible
- string is added to support this change - "qcom,sdhci-msm-v5".
- full compatible strings with SoC and version:
- "qcom,apq8084-sdhci", "qcom,sdhci-msm-v4"
- "qcom,msm8226-sdhci", "qcom,sdhci-msm-v4"
- "qcom,msm8953-sdhci", "qcom,sdhci-msm-v4"
- "qcom,msm8974-sdhci", "qcom,sdhci-msm-v4"
- "qcom,msm8916-sdhci", "qcom,sdhci-msm-v4"
- "qcom,msm8992-sdhci", "qcom,sdhci-msm-v4"
- "qcom,msm8994-sdhci", "qcom,sdhci-msm-v4"
- "qcom,msm8996-sdhci", "qcom,sdhci-msm-v4"
- "qcom,qcs404-sdhci", "qcom,sdhci-msm-v5"
- "qcom,sc7180-sdhci", "qcom,sdhci-msm-v5";
- "qcom,sc7280-sdhci", "qcom,sdhci-msm-v5";
- "qcom,sdm845-sdhci", "qcom,sdhci-msm-v5"
- "qcom,sdx55-sdhci", "qcom,sdhci-msm-v5";
- "qcom,sm8250-sdhci", "qcom,sdhci-msm-v5"
- NOTE that some old device tree files may be floating around that only
- have the string "qcom,sdhci-msm-v4" without the SoC compatible string
- but doing that should be considered a deprecated practice.
-
-- reg: Base address and length of the register in the following order:
- - Host controller register map (required)
- - SD Core register map (required for controllers earlier than msm-v5)
- - CQE register map (Optional, CQE support is present on SDHC instance meant
- for eMMC and version v4.2 and above)
- - Inline Crypto Engine register map (optional)
-- reg-names: When CQE register map is supplied, below reg-names are required
- - "hc" for Host controller register map
- - "core" for SD core register map
- - "cqhci" for CQE register map
- - "ice" for Inline Crypto Engine register map (optional)
-- interrupts: Should contain an interrupt-specifiers for the interrupts:
- - Host controller interrupt (required)
-- pinctrl-names: Should contain only one value - "default".
-- pinctrl-0: Should specify pin control groups used for this controller.
-- clocks: A list of phandle + clock-specifier pairs for the clocks listed in clock-names.
-- clock-names: Should contain the following:
- "iface" - Main peripheral bus clock (PCLK/HCLK - AHB Bus clock) (required)
- "core" - SDC MMC clock (MCLK) (required)
- "bus" - SDCC bus voter clock (optional)
- "xo" - TCXO clock (optional)
- "cal" - reference clock for RCLK delay calibration (optional)
- "sleep" - sleep clock for RCLK delay calibration (optional)
- "ice" - clock for Inline Crypto Engine (optional)
-
-- qcom,ddr-config: Certain chipsets and platforms require particular settings
- for the DDR_CONFIG register. Use this field to specify the register
- value as per the Hardware Programming Guide.
-
-- qcom,dll-config: Chipset and Platform specific value. Use this field to
- specify the DLL_CONFIG register value as per Hardware Programming Guide.
-
-Optional Properties:
-* Following bus parameters are required for interconnect bandwidth scaling:
-- interconnects: Pairs of phandles and interconnect provider specifier
- to denote the edge source and destination ports of
- the interconnect path.
-
-- interconnect-names: For sdhc, we have two main paths.
- 1. Data path : sdhc to ddr
- 2. Config path : cpu to sdhc
- For Data interconnect path the name supposed to be
- is "sdhc-ddr" and for config interconnect path it is
- "cpu-sdhc".
- Please refer to Documentation/devicetree/bindings/
- interconnect/ for more details.
