Subject: [PATCH V2 0/3] Internal voltage control for qcom SDHC
Date: Thu, 21 May 2020 20:53:32 +0530 [thread overview]
Message-ID: <1590074615-10787-1-git-send-email-vbadigan@codeaurora.org> (raw)
In-Reply-To: <1589541535-8523-1-git-send-email-vbadigan@codeaurora.org>
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.
Changes since V1:
- Removed setting load for Vmmc regulator while turning it on/off.
Instead setting the active load once during probe.
- Simplified handlng of supplies for BUS_ON/OFF cases in shci_msm_handle_pwr_irq().
- Moved common code out of switch case in sdhci_msm_start_signal_voltage_switch().
- Updated variable name to sdhci_core_to_disable_vqmmc.
- Updated pr_err logs to dev_err logs.
