Some TV support specific video mode that different with
CEA standard, and it's pixel clock not comply CEA standard.
But audio configuration paramter N and CTS should follow CEA standard.
So audio may not work in these specific video mode.
Filter video mode get from EDID, only keep standard CEA video mode
in the modelist.

Early versions of this driver used a set of entropy generation parameters
inherited from QorIQ devices. Those parameters were a hardcoded set
based upon internally-suggested values, and worked well on QorIQ. However,
for certain mx6 devices, oscillator values were found to be exceeding
the upper limit, and so RNG instantiation was failing in those cases.
This code improves initialization by (a) making sure the oscillator
divider is set to a known value, and (b) converting the parameter selection
to a symbolic compiler-generated form, instead of using embedded
magic number constants.
The calculation is now based on the definition of RNG4_ENT_CLOCKS_SAMPLE,
which defaults to 1600 unless overridden by something. The lower limit
is then set as /4, and the upper limit set to *8.

the original low memory killer only take care of system memory accounting,
but for so large shared memory occupy by GPU, and each process memory
killer account become unfair, very large 3D game will not killed firstly
if it going to background.
Add this account to let real large memory user get killed if going to background
eg, the "angry bird Space" will acquire 68,215,360 GPU memory for 1-6 toll-gate.
The test show it can quicker recovery from memory shortage situation,
since it's very like to be killed after add so much GPU memory for such 3D game.

Bug: VPU easily hang during suspend/resume standby mode i.MX6Q/i.MX6DL
Fix: standby mode doesn't power off/on PU but changes voltage instead, thus
VPU requires a reset cause there's always chance some cell is on
unstable state after voltage change
suspend/resume DSM is OK because it power off/on PU and probably there is a
power-on-reset sequence embedded in SOC

The synchronize_rcu() call resulting from making every serial driver
wake-up capable (commit b3b708fa) slows boot down on my Tegra2x system
(with CONFIG_PREEMPT disabled).
But this is avoidable since it is the device_set_wakeup_enable() and then
subsequence disable which causes the delay. We might as well just make
the device wakeup capable but not actually enable it for wakeup until
needed.
Effectively the current code does this:
device_set_wakeup_capable(dev, 1);
device_set_wakeup_enable(dev, 1);
device_set_wakeup_enable(dev, 0);
We can just drop the last two lines.
Before this change my boot log says:
[ 0.227062] Serial: 8250/16550 driver, 4 ports, IRQ sharing disabled
[ 0.702928] serial8250.0: ttyS0 at MMIO 0x70006040 (irq = 69) is a Tegra

However, SDMA can meet more kinds of DMA operation mode requirement. The

In this patch,
1 Construct a new enum sdma_mode to declare more kind of SDMA
modes. This new variable would replace the old flags.
2 Init sdma_mode to unvalid every time allocating a SDMA channel

busy with the high priority task, which will cause the thermal

To allocate an SDMA channel, imx_dma_data struct is need. However,
if the member dma_request_p2p is not set to 0 before configuration,
SDMA driver would treat the channel as p2p(periphal to periphal) DMA and
set SDMA channel context in p2p way. In the worst case, SDMA would
access some unexisted address cause of mis configuration above and thus
cause kernel panic or hang.
In this patch, set imx_dma_data struct to 0 once it is allocated from
stack.
