[PATCH v4 7/9] dt-bindings: mmc: sdhci-msm: add ICE registers and clock

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Eric Biggers <ebiggers@xxxxxxxxxx>

Document the bindings for the registers and clock for the MMC instance
of the Inline Crypto Engine (ICE) on Snapdragon SoCs.  These bindings
are needed in order for sdhci-msm to support inline encryption.
