PD#148057: for m8bb m200 platform, we have the latest linux kernel
and a relative old version uboot running on it. For some historic
resons, the unifykey data stored in emmc/nand has totally different
format, which means the key stored by old uboot cannot be fetched
out by new kernel. To solve this problem, we have to support both
the old and new unifykey dataformat in lasted kernel.

PD#146539: usb: fix adb reboot panic.
Avoid kernel panic caused by race condition. For example,
1. In the ffs_epfile_io function, data buffer is allocated
for non-halt requests and the address of this buffer is
writed to usb controller registers.
2. After adb process be killed, data buffer is freed and
this memory is allocated for the other. But the address
is hold by the controller.
3. Adbd in PC is running. So, the controller receive the
data and write to this memory.
4. The value of this memory is modified by the controller.
This could cause the kernel panic.
To avoid this, during FunctionFS mount, we allocated the
data buffer for requests. And the memory resources has
been released in kill_sb.

PD#147238: enable DRM driver on kernel 4.9
The Amlogic Meson Display controller is composed of several components :
DMC|---------------VPU (Video Processing Unit)----------------|------HHI------|
| vd1 _______ _____________ _________________ | |
D |-------| |----| | | | | HDMI PLL |
D | vd2 | VIU | | Video Post | | Video Encoders |<---|-----VCLK |

A | osd1 | | | Blenders | | Encl ----------|----|---------------|
M |-------|______|----|____________| |________________| | |
___|__________________________________________________________|_______________|
VIU: Video Input Unit
---------------------
The Video Input Unit is in charge of the pixel scanout from the DDR memory.
It fetches the frames addresses, stride and parameters from the "Canvas" memory.
This part is also in charge of the CSC (Colorspace Conversion).
It can handle 2 OSD Planes and 2 Video Planes.
VPP: Video Post Processing
--------------------------
The Video Post Processing is in charge of the scaling and blending of the
various planes into a single pixel stream.
There is a special "pre-blending" used by the video planes with a dedicated
scaler and a "post-blending" to merge with the OSD Planes.
The OSD planes also have a dedicated scaler for one of the OSD.
VENC: Video Encoders
--------------------
The VENC is composed of the multiple pixel encoders :
- ENCI : Interlace Video encoder for CVBS and Interlace HDMI
- ENCP : Progressive Video Encoder for HDMI
- ENCL : LCD LVDS Encoder
The VENC Unit gets a Pixel Clocks (VCLK) from a dedicated HDMI PLL and clock
tree and provides the scanout clock to the VPP and VIU.
The ENCI is connected to a single VDAC for Composite Output.
The ENCI and ENCP are connected to an on-chip HDMI Transceiver.
This driver is a DRM/KMS driver using the following DRM components :
- GEM-CMA
- PRIME-CMA
- Atomic Modesetting
- FBDev-CMA
For the following SoCs :
- GXBB Family (S905)
- GXL Family (S905X, S905D)
- GXM Family (S912)
The current driver only supports the CVBS PAL/NTSC output modes, but the
CRTC/Planes management should support bigger modes.
But Advanced Colorspace Conversion, Scaling and HDMI Modes will be added in
a second time.
The Device Tree bindings makes use of the endpoints video interface definitions
to connect to the optional CVBS and in the future the HDMI Connector nodes.
HDMI Support is planned for a next release.

will return the next node. The data will be used by

This change adds flags to flat_binder_object.flags
to allow indicating a minimum scheduling policy for
the node. It also clarifies the valid value range
for the priority bits in the flags.
Internally, we use the priority map that the kernel
uses, e.g. [0..99] for real-time policies and [100..139]
for the SCHED_NORMAL/SCHED_BATCH policies.

Instead of pushing new transactions to the process
waitqueue, select a thread that is waiting on proc
work to handle the transaction. This will make it
easier to improve priority inheritance in future
patches, by setting the priority before we wake up
a thread.
If we can't find a waiting thread, submit the work
to the proc waitqueue instead as we did previously.

Removes the process waitqueue, so that threads
can only wait on the thread waitqueue. Whenever
there is process work to do, pick a thread and
wake it up.
This also fixes an issue with using epoll(),
since we no longer have to block on different
waitqueues.
