Subject: [RFC v3 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 Georgi Djakov [RFC]
(https://lkml.org/lkml/2018/10/11/499) and

Saravana Kannan [PATCH v6]
(https://lkml.org/lkml/2019/12/6/740)

change from RFC v2 -> v3 changes:
- Modified interconnect bandwidth support using OPP framework.
- Addressed review comments on v2.

  mmc: sdhci-msm: Add interconnect bus bandwidth scaling support
  dt-bindings: mmc: sdhci-msm: Add interconnect BW scaling strings
