In order to maximise performance of the LCD Controller's 64-bit AXI bus, for any give speed bin of the device, the AXI master interface clock(ACLK) clock can be up to CPU_frequency/2, which is already capable of optimal performance. In general, ACLK is always expected to be equal to CPU_frequency/2. APB slave interface clock(PCLK) and Main processing clock(PCLK) both are tied to the same clock as ACLK. This change followed the LS1028A Architecture Specification Manual. Signed-off-by: Wen He <wen.he_1@nxp.com> Acked-by: Li Yang <leoyang.li@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
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.
