During HW readout/sanitization CRTCs can be disabled only if they don't have an attached encoder (and so the encoder disable hooks don't need to be called). An upcoming patch will need to disable CRTCs also with an attached encoder, so add support for this. For bigjoiner configs the encoder disabling hooks require the slave CRTC states, so add these too to the atomic state. Since the connector atomic state is already up-to-date when the CRTC is disabled the connector state needs to be updated (reset) after the CRTC is disabled, make this so. Follow the proper order of disabling first all bigjoiner slaves, then any port synced CRTC slaves followed by the CRTC originally requested to be disabled. v2: - Fix calculating the bigjoiner_masters mask in a port sync config, (Ville) - Keep _noatomic suffix in intel_crtc_disable_noatomic(). (Ville) - Rebase on full CRTC state reset in this patchset, not requiring resetting the bigjoiner state separately and (instead) resetting the full atomic CRTC and related global state after all linked pipes got disabled. - Disable portsync slaves before a portsync master. - Disable a portsync master if a linked portsync slave is disabled. v3: (Ville) - Use s/u32/u8 for transcoder and pipe masks. - Use is_power_of_2() instead of hweight()==1.

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.
