On some systems, we come out of the bootloader with some gates set with the clock "enabled" but the reset also asserted. Since8a53fc511c"clk: aspeed: Prevent reset if clock is enabled" we check that enabled bit in aspeed_clk_enabled(), and do nothing if already set. This breaks when the above scenario occurs, as the clock is enabled, but the reset still needs to be lifted. This patch fixes it by also checking the reset bit (if any) and treating a gate in "reset" as being disabled.

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.
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.
