Adds a OP-TEE driver which also can be compiled as a loadable module.
* Targets ARM and ARM64
* Supports using reserved memory from OP-TEE as shared memory
* CMA as shared memory is optional and only tried if OP-TEE doesn't
supply a reserved shared memory region
* Probes OP-TEE version using SMC
Hi,
This patch set introduces a generic TEE subsystem. The TEE subsystem will be
able contain drivers for various TEE implementations. A TEE (Trusted
Execution Environment) is a trusted OS running in some secure environment,
for example, TrustZone on ARM cpus, or a separate secure co-processor etc
Initial patch for generic TEE subsystem.
This subsystem provides:
* Registration/un-registration of TEE drivers.
* Shared memory between normal world and secure world.
* Ioctl interface for interaction with user space.
A TEE (Trusted Execution Environment) driver is a driver that interfaces
with a
Hello, device tree folks,
Can I ask a little piece of advice?
Which is a preferred way for specifying an interrupt property,
interrupt-parent & interrupts, or interrupts-extended ?
There is only one interrupt controller on my SoC,
so I think either should work enough for me.

Based on the datasheet found here:
http://www.richtek.com/download_ds.jsp?p=RT9455
Updates from the previous version:
- replaced license GPLv2 with GPL
- replaced vendor prefix rt with richtek
- replaced uppercase properties names from devicetree with lowercase separated
by dash properties names
Export the oversampling ratio so that the user can change the
number of repetions for x/y/z axis.
The sampling frequency is limited by the oversampling ratio.
The available sampling frequencies might change depending
on the values of oversampling_ratio.

This mailbox driver provides a single mailbox channel to write 32-bit
values to the VPU and get a 32-bit response. The Raspberry Pi
firmware uses this mailbox channel to implement firmware calls, while
Roku 2 (despite being derived from the same firmware tree) doesn't.

v11:
- reduce the patch series to adding the tda998x codec only
v10:
- add the generic dt-card
- define the audio ports from a DT graph of ports (Russell King)
- reuse HDMI constants (Andrew Jackson - Jyri Sarha)
- alloc rate_constraints in
Two kinds of ports may be declared in a DT graph of ports: video and audio.
This patch accepts the port value from a video port as an alternative
to the video-ports property.
It also accepts audio ports in the case the transmitter is not used as
a slave encoder.

Given this patch-set has been on the list for some time now and we
haven't heard from Alessandro in all that time, I'm going to just
apply the set and send out a pull-request to the other Maintainers.
No point waiting any longer IMHO.

This patch set adds support for Exynos SROM controller DT based driver.
Currently SROM register sets are used only during S2R, so driver
basically added for taking care of S2R. It will help us in removing
static mapping from exynos.c and other extra code handline during S2R.
This patch set also up
This patch adds Exynos SROM controller driver which will handle
