Subject: [PATCH V2 0/2] Add SDHC interconnect bandwidth scaling 


Add interconnect bandwidths for SDHC driver using OPP framework that
is required by SDHC driver based on the clock frequency and bus width
of the card. 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].
