The Rockchip DMC devfreq driver is the only user of the Rockchip DDR
clock.
Both drivers perform SMC calls to the Trusted-Firmware A to run SiP
services related to the DDR memory.
This commit centralizes the SiP services in the DMC devfreq driver and
removes the DDR clock which becomes useless.

arm64 has a feature called Top Byte Ignore, which allows to embed pointer

Change the kernfs_node.priv to store the cgroup_subsys_state (CSS) pointer
for directories, instead of storing cgroup pointer. This is done in order
to support files within the cgroup associated with devices. We require
of_css() to return the device-specific CSS pointer for these files.
Cc:
Here we update memory cgroup to enable the newly introduced per-device
framework. As mentioned in the prior patch, the intent here is to allow
drivers to have their own private cgroup controls (such as memory limit)
to be applied to device resources instead of host system resources.
In summary,
i915 driver now includes DRIVER_CGROUPS in feature bits.
To charge device memory allocations, we need to (1) identify appropriate
cgroup to charge (currently decided at object creation time), and (2)
make the charging call at the time that memory pages are being allocated.
For (1), see prior DRM
In containerized or virtualized environments, there is desire to have
controls in place for resources that can be consumed by users of a GPU
device. For this purpose, we extend control groups with a mechanism
for device drivers to register with cgroup subsystems.
Device drivers (GPU or other) are
With new cgroups per-device framework, registration with memory cgroup
subsystem can allow us to enforce limit for allocation of device memory
against process cgroups.

will register the device with cgroups. Doing so allows
In containerized or virtualized environments, there is desire to have
