Subject: [RFC v6 0/2] Add SDHC interconnect bandwidth scaling
Date: Mon, 23 Mar 2020 19:55:00 +0530 [thread overview]
Message-ID: <1584973502-14775-1-git-send-email-ppvk@codeaurora.org> (raw)
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
[RFC] mmc: host: sdhci-msm: Use the interconnect API
(https://lkml.org/lkml/2018/10/11/499) and
[PATCH v6] Introduce Bandwidth OPPs for interconnects
(https://lkml.org/lkml/2019/12/6/740)

mmc: sdhci-msm: Add interconnect bus bandwidth scaling support

RFC v5 -> v6:
- Added Rob's Acked-by and Bjorn Reviewed-by for the DT patch.
- Added new goto jump tag to put both icc paths.
- Removed bus vote data error check and added is_null check.
- Addressed minor code style comments.
