We can use iopoll for checking the EOCZ (end of conversion) bit. And with this we now also want to handle the timeout errors properly. For omap3, we need about 1.2ms for the single mode sampling to wait for EOCZ down, so let's use 1.5ms timeout there. Waiting for sampling to start is faster and we can use 1ms timeout.

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.
