Linux kernel source tree
cc2f156a33
The GPIO controllers in most Rockchip SoCs are part of power domains that are always powered on, i.e. PD_BUS or PD_PMU. These always powered on power domains have typically not been described in the device tree. Because these power domains have been left out of the device tree there has not been any real need to properly describe the GPIO controllers power domain. On RK3528 the GPIO controllers are spread out among the described PD_RKVENC, PD_VO and PD_VPU power domains. However, one GPIO controller belong to an undescribed always powered on power domain. Add support to describe an optional power-domains for the GPIO controllers in Rockchip SoCs.

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.
