The Rockchip Video Decoder driver is expecting that the values in a
scaling list are in zig-zag order and applies the inverse scanning process
to get the values in matrix order.
Commit 0b0393d59e ("media: uapi: h264: clarify expected

Previously, the output format was programmed as part of the ioctl()
handler. However, this has two problems:
1) If there are multiple active streams with different output
formats, the hardware will use whichever format was set last
for both streams. Similarly, an ioctl() done in an inactive
context will wrongly affect other active contexts.
2) The registers are written while the device is not actively
streaming. To enable runtime PM tied to the streaming state,
all hardware access needs to be moved inside cedrus_device_run().
The call to cedrus_dst_format_set() is now placed just before the
codec-specific callback that programs the hardware.

There's a hack at the driver that selects a different table
for a BYT tablet, which sets the maximum frequency to 320 MHz,
instead of 400 MHz.
After looking at the Intel Aero Yocto's version from:
https://download.01.org/aero/deb/pool/main/l/linux-4.4.76-aero-1.3/
It was noticed that this depends on an Android-specific modprobe parameter,
which uses a macro (INTEL_MID_BOARD) from this file:
arch/x86/include/asm/spid.h
>From the comments there, it looks like this macro parses a
variable passed at boot time:
cmdline : androidboot.spid=vend:cust:manu:plat:prod:hard
The devices in question are identified there as:
INTEL_BYT_TABLET_BLK_PRO = 0x0000
INTEL_BYT_TABLET_BLK_ENG = 0x8000
Well, this is something that we don't have upstream. So,
without further details about that, we can't really parse it.
If we ever end supporting those devices with the upstream driver,
this patch can be reverted and the device can be detected
via DMI (or maybe via PCI ID?).
