The main addition is the split of bus and driver into distinct modules The FF-A bus module is initialized at subsys_initcall level when builtin. FF-A drivers initialization is now changed to module_init level so that pKVM ffa proxy is all setup and running in case pKVM hypervisor needs to trap and handle FF-A calls. One of the reason for not having this split from the beginning is the need to workaround the FF-A v1.0 NULL UUID. The FF-A bus layer called into FF-A driver and populated the device UUID if it matches with the driver attempting to match. Moving the workaround away from the FF-A bus layer to the FF-A core driver as a bus notifier will help to remove the dependency. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEunHlEgbzHrJD3ZPhAEG6vDF+4pgFAmZ1dMsACgkQAEG6vDF+ 4phkJBAA0ybLo3iExgUTUi7G+zoCvbnt2vCWGhcd/TnOHuQYEl2pJG8N4tAytBDd CsUpWtX7nzo2DKV9UOM+TjyFVP0J2m8UvlUVb+X2CNbg2vUfVZLm831EN7WbdS1w yXAgyf3QMaLrmT9QVhf5FZDLJF2YV589cdBLML8PsJjbkKE5q3Xre2w3uv7dW7uE 21zfAxrlqdbj3AuWSTt9aBxnkOXifhw93raoFL3Jr3RHOhaIot7KJbsFUFPNikZQ Q5daFnwGkKMslW18LUBB7VYlkDBtsHe4QPFddMKXRSufdQk65kB4q/TL79QDoSQ3 7CgJZ2yl/gCeLr5nEmTGeQVnxaqQDE0bw1q9DqskcE/2Tfo916l260qix3qzLmtF /nmkP8geLijRAqkeAKXxj0vr5j3CWSGn2ziLi0167QUPnYBvtAgKKuPVUwZG3GBE hLwPIiclzJA5HnswsQm8zEOWwF1po5mycRV+dxINRWt6rh4jhSWVZvYH77kg6t0I wEc7mauh879G5CHuLGiwSof6R2pDzhXRwX9Q37kpYoq10/Vm9KPnm5XeUOQZ5F/s lZH8PZfds6M7tALrc9nsdMMF3YMU31oH9bpBYYQrad5J89Cx41OeNM41BkKLK7dW K2pJ7wOL3Us7a/gNszbL7kUG7wRVe/qVNouhC0y3uGOPFNScuTs= =Kl7/ -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmZ9eiUACgkQYKtH/8kJ Uif0zBAAjk+BS5UP627Uhej+cXrZhHkwRrj6mJ9C4wFYR6672vxhdMh+wPZcbh/H yl8/Z+1TUBTmVmQtmKyi0cRhFFX12I0FyXpa7n7WVMhXnmvYRd2SjbRctYfc3pxW C1TqHxM3a7bkaknzM4N5Uuj3qpwV74Hbp+rfaEdH4pL44vV2o2OkueM5IsBpgnSb Pe1Wn6zXgXFIQyo8aVF7DGxNuBleNgxtX+zfcY5694IGKDKn2llsKxVeM5cDNg2q WmKQ7rz7ZqpkDxQBL3wLZnd7lziSPVQ9jJ3m7ECzj7W0RAPQTskeNIlKyKK+9kHB HmmiOlLbQu+lirgZ15N3t8kiYFNVh8HDK+p5w/dgUD4EAT+TZgQgun9d61VLf6AT uD4XF0fPB3B3PKAfOhp7ZOU6sZH4uibFh+8RAm9xRJjXYvA0Il7gcwbC45O1dQK7 cqusKECEPTKsFggj0fuYgfDiNEgZpGSFjKAfYvB63aRZjoj7L29YhMl0Hwr87dFC vsoJgs0pDW+V4ajqDoRPOLWkDwafMWjIrXxDFTEEw8xLQMTSOUC2Yei4sPDViLLG 3HTlssc1gO2axhrn5SpxPCgX+UruC4MIacj7kntv1VhYmOE5yoOLeTGV6lWA0LGm NSqz0Gr8N+ycbtU2hNu/HULt6TViI3/SwRr2KK45rWHK7qHBu0Q= =tW+N -----END PGP SIGNATURE----- Merge tag 'ffa-updates-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm FF-A driver updates for v6.11 The main addition is the split of bus and driver into distinct modules The FF-A bus module is initialized at subsys_initcall level when builtin.

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.
