Subject: [PATCH V3 0/2] Deactivate CQE during SDHC reset
Date: Fri,  6 Mar 2020 19:38:41 +0530	[thread overview]
Message-ID: <1583503724-13943-1-git-send-email-vbadigan@codeaurora.org> (raw)
In-Reply-To: <1582890639-32072-1-git-send-email-vbadigan@codeaurora.org>

Host controllers can reset CQHCI either directly or as a consequence
of host controller reset. In the later case, driver should deactivate
CQHCI just before reset to puts the CQHCI driver into a state that is
consistent with that h/w state.

Changes sicne V2:
	- Added support cqhci_deactivate()
	- Use cqhci_deactivate() instead of cqhci_disable().
	- Deactivate CQCHI just before SDHC reset.

Changes since V1:
	- Disable CQE only when SDHC undergoes s/w reset for all.
