Subject: [PATCH v4 1/4] dt-bindings: mmc: Add dll-hsr-list for HS400 and HS200 modes

From: Sachin Gupta <quic_sachgupt@...cinc.com>

Document the 'dll-hsr-list' property for MMC device tree bindings.
The 'dll-hsr-list' property defines the DLL configurations for HS400
and HS200 modes.

QC SoCs can have 0 to 4 SDHCI instances, and each one may need
different tuning.
