Subject: [PATCH V1 0/3] Internal voltage control for qcom SDHC
On qcom SD host controllers voltage switching be done after the HW
is ready for it. The HW informs its readiness through power irq.
The voltage switching should happen only then.
So added support to register voltage regulators from the msm driver
and use them.
This patchset was posted long back but not actively pursued
https://lore.kernel.org/linux-arm-msm/1539004739-32060-1-git-send-email-vbadigan@codeaurora.org/
So posting it as fresh patchset.
Veerabhadrarao Badiganti (1):
dt-bindings: mmc: Supply max load for mmc supplies
Vijay Viswanath (2):
mmc: sdhci-msm: Use internal voltage control
mmc: sdhci: Allow platform controlled voltage switching
