Jonathan Bell ccb5099195 mmc: use downstream DT property to modify CQE and/or SD CQ behaviour
Implement a tristate-style option for "supports-cqe". If the property is
absent or zero, disable CQ completely. For 1, enable CQ unconditionally
for eMMC cards, and known-good SD cards. For 2, enable for eMMC cards,
and all SD cards that are not known-bad.

The sdhci-brcmstb driver needs to know about the tristate as its probe
sequence would otherwise override a disable in mmc_of_parse().

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.
