Subject: [PATCH V4] arm64: dts: qcom: sc7280: Add nodes for eMMC and SD card
Date:   Wed, 16 Jun 2021 14:53:01 +0530
Message-Id: <1623835381-29696-1-git-send-email-sbhanu@codeaurora.org>
Precedence: bulk

Add nodes for eMMC and SD card on sc7280.

Signed-off-by: Shaik Sajida Bhanu <sbhanu@codeaurora.org>
---

This change is depends on the below patch series:
https://lore.kernel.org/patchwork/cover/1418814/

Changes since V3:
	- Changed pinconfig names as suggested by Konrad Dybcio.
	- Removed extra lines and aligned some of lines as suggested by
	  Bjorn Andersson.

Change since V2:
	- Added leading zero's for register address and "qcom,sc7280-sdhci"
	  string in compatible as suggested by Stephen Boyd and Doug.
	- Removed max-frequency flag, no-mmc and no-sdio flags
	  for Sd card as suggested by Doug and Stephen Boyd.
	- Moved non-removable, no-sd, no-sdio and some pin config
	  changes from soc to board dts file as suggested by Doug.
	- Removed sleep state for CD line and drive-strength for input pins
	  as suggested by Doug.
	- Updated bus vote numbers for eMMC and SD card.

Changes since V1:
	- Moved SDHC nodes as suggested by Bjorn Andersson.
	- Dropped "pinconf-" prefix as suggested by Bjorn
	  Andersson.
	- Removed extra newlines as suggested by Konrad Dybcio.
	- Changed sd-cd pin to bias-pull-up in sdc2_off as suggested by
	  Veerabhadrarao Badiganti.
	- Added bandwidth votes for eMMC and SD card.
