Brian Norris 3dce99e2eb mmc: sdhci-tegra: Fix SDHCI_RESET_ALL for CQHCI 
commit 8360784494 upstream.

[[ NOTE: this is completely untested by the author, but included solely
    because, as noted in commit df57d73276 ("mmc: sdhci-pci: Fix
    SDHCI_RESET_ALL for CQHCI for Intel GLK-based controllers"), "other
    drivers using CQHCI might benefit from a similar change, if they
    also have CQHCI reset by SDHCI_RESET_ALL." We've now seen the same
    bug on at least MSM, Arasan, and Intel hardware. ]]

SDHCI_RESET_ALL resets will reset the hardware CQE state, but we aren't
tracking that properly in software. When out of sync, we may trigger
various timeouts.

It's not typical to perform resets while CQE is enabled, but this may
occur in some suspend or error recovery scenarios.

Include this fix by way of the new sdhci_and_cqhci_reset() helper.

This patch depends on (and should not compile without) the patch
entitled "mmc: cqhci: Provide helper for resetting both SDHCI and
CQHCI".

Fixes: 3c4019f979 ("mmc: tegra: HW Command Queue Support for Tegra SDMMC")

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
