Linus Torvalds cc0f7c3f97 soc: driver updates for 6.11 
The updates to the mediatek, allwinner, ti, tegra, microchip, stm32,
 samsung, imx, zynq and amlogic platoforms are farily small maintenance
 changes, either addressing minor mistakes or enabling additional hardware.
 
 The qualcomm platform changes add a number of features and are larger
 than the other ones combined, introducing the use of linux/cleanup.h
 across several drivers, adding support for Snapdragon X1E and other
 SoCs in platform drivers, a new "protection domain mapper" driver, and a
 "shared memory bridge" driver.
 
 The cznic "turris omnia" router based on Marvell Armada gets a platform
 driver that talks to the board specific microcontroller.
 
 The reset and cache subsystems get a few minor updates to SoC specific
 drivers, while the ff-a, scmi and optee firmware drivers get some
 code refactoring and new features.

title: Last Level Cache Controller
maintainers:
- Bjorn Andersson <andersson@kernel.org>
description: |
LLCC (Last Level Cache Controller) provides last level of cache memory in SoC,
that can be shared by multiple clients. Clients here are different cores in the
SoC, the idea is to minimize the local caches at the clients and migrate to
common pool of memory. Cache memory is divided into partitions called slices
which are assigned to clients. Clients can query the slice details, activate
and deactivate them.
