In normal case, dsc power domain will enable when crtc enable and disabled when crtc disable. When enable dsc in uboot to show logo, the dsc in kernel driver can't know the real power domain status, which will trigger something wrong when disable/endale dsc power domain. To avoid this issue, we check the dsc power domain status when vop_initial. the dsc power domain get in vop_initial function is enabled only when dsc is enabled in uboot and enter into kernel driver. It need to update dsc power domain status in this case. Signed-off-by: Sandy Huang <hjc@rock-chips.com> Change-Id: I9641373c2c8facc17ff90d4141909bcc3ac6b13d
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.
