Tegra186 CQHCI host has a known bug where CQHCI controller selects DATA_PRESENT_SELECT bit to 1 for DCMDs with R1B response type and since DCMD does not trigger any data transfer, DCMD task complete happens leaving the DATA FSM of host controller in wait state for the data. This effects the data transfer tasks issued after the DCMDs with R1b response type resulting in timeout. SW WAR is to set CMD_TIMING to 1 in DCMD task descriptor. This bug and SW WAR is applicable only for Tegra186 and not for Tegra194. This patch implements this WAR thru NVQUIRK_CQHCI_DCMD_R1B_CMD_TIMING for Tegra186 and also implements update_dcmd_desc of cqhci_host_ops interface to set CMD_TIMING bit depending on the NVQUIRK.

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.
