Here is the MHI patch set for v5.11. Most of the patches are cleanups and fixes but there are some noticeable changes too: 1. Loic finally removed the auto-start option from the channel parameters of the MHI controller. It is the duty of the client drivers like qrtr to start/stop the channels when required, so we decided to remove this option. As a side effect, we changed the qrtr driver to start the channels during its probe and removed the auto-start option from ath11k controller. **NOTE** Since these changes spawns both MHI and networking trees, the patches are maintained in an immutable branch [1] and pulled into both mhi-next and ath11k-next branches. The networking patches got acks from ath11k and networking maintainers as well. 2. Loic added a generic MHI pci controller driver. This driver will be used by the PCI based Qualcomm modems like SDX55 and exposes channels such as QMI, IP_HW0, IPCR etc... 3. Loic fixed the MHI device hierarchy by maintaining the correct parent child relationships. Earlier all MHI devices lived in the same level under the parent device like PCIe. But now, the MHI devices belonging to channels will become the children of controller MHI device. 4. Finally Loic also improved the MHI device naming by using indexed names such as mhi0, mhi1, etc... This will break the userspace applications depending on the old naming convention but since the only one user so far is Jeff Hugo's AI accelerator apps, we decided to make this change now itself with his agreement. 5. Bhaumik fixed the qrtr driver by stopping the channels during remove. This patch also got ack from networking maintainer and we decided to take it through MHI tree (via immutable branch) since we already had a qrtr change.

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.
