Fork of reMarkable kernel https://github.com/reMarkable/linux

The Linear Technology LTC2631, LTC2633 and LTC2635 are very similar
to the AD5064 device, in particular the LTC2627.
This patch adds support for those devices. Only the LTC2633 has been
tested, which is the 2-channel variant. The LTC2631 is the 1-channel,
and the LTC2635 the 4-channel version. The actual DAC resolution depends
on the exact chip type and can be 12, 10 or 8 bits, using the upper bits
so this has no effect on the register map. The internal reference is set
to 2.5V on "L" versions, and it's 4.096V for "H" versions.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
