Linux kernel source tree

Several of the manuals for devices supported by this driver describes the need for a minimum wait time before the chip is ready to receive next command. This wait time is already implemented in the driver as a ltc_wait_ready function with a driver defined wait time of 100 ms, and is considered for specific devices before reading/writing data on the pmbus. Since this driver uses the default pmbus_regulator_ops for the enable/ disable/is_enabled functions we should add a driver specific callback for write_byte_data to prevent bypassing the wait time recommendations for the following devices: ltc3880/ltc3882/ltc3883/ltc3884/ltc3886/ ltc3887/ltc3889/ltm4664/ltm4675/ltm4676/ltm4677/ltm4678/ltm4680/ltm4686/ ltm4700/ltc7880.

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.
