Otherwise, the system clocks may run at minimum clock speed and thus affecting the performance. This change is based on [1] [Patch v8] Introduce OPP bandwidth bindings (https://lkml.org/lkml/2020/5/12/493) [2] [Patch v3 09/17] mmc: sdhci-msm: Fix error handling for dev_pm_opp_of_add_table() (https://lkml.org/lkml/2020/5/5/491) [3] [RFC v6 2/2] dt-bindings: mmc: sdhci-msm: Add interconnect BW scaling strings (https://lkml.org/lkml/2020/3/23/409) as there were no extra changes made on [3], retaining the Acked-by and Reviewed-by sign-off from [3].
