Previously the MR and SCR registers were just set with the supposedly
required values, from cached register values (cached reg content
initialized to zero).
All parts fixed here did not consider the current register (cache)
content, which would make future support of cs_setup, cs_hold, and
cs_inactive impossible.
Setting SCBR in atmel_qspi_setup() erases a possible DLYBS setting from
atmel_qspi_set_cs_timing(). The DLYBS setting is applied by ORing over
the current setting, without resetting the bits first. All writes to MR
did not consider possible settings of DLYCS and DLYBCT.

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 reStructuredText 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.
