This works around a hardware bug.
From "Chip Errata for the i.MX 6Dual/6Quad"
ERR006687 ENET: Only the ENET wake-up interrupt request can wake the
system from Wait mode.
The ENET block generates many interrupts. Only one of these interrupt lines
is connected to the General Power Controller (GPC) block, but a logical OR
of all of the ENET interrupts is connected to the General Interrupt Controller
(GIC). When the system enters Wait mode, a normal RX Done or TX Done does not
wake up the system because the GPC cannot see this interrupt. This impacts
performance of the ENET block because its interrupts are serviced only when
the chip exits Wait mode due to an interrupt from some other wake-up source.

Also, apply same change to imx6qdl-nitrogen6x.
This change may not be appropriate for all boards.
Sabre Lite uses GPIO6 as a power down output for a ov5642
camera. As this expansion board does not yet work with mainline,
this is not yet a conflict. It would be nice to have an alternative
fix for boards where this is a problem.
For example Sabre SD uses GPIO6 for I2C3_SDA. It also
has long ping times currently. But cannot use this fix
without giving up a touchscreen.
Its ping times are also random.

The input reg is set to 0x3c to set IOMUX_OBSRV_MUX1 to ENET_IRQ.
The mux reg value is 0x11, so that the observable mux is routed to
this pin and to the gpio controller(sion bit). These magic values

ARM: dts: imx: specify the value of audmux pinctrl instead of 0x80000000
We must specify the value of audmux pinctrl if we want to use pinctrl_pm().
Thus change bypass value 0x80000000 to what we exactly need.
This patch also seperately unset PUE bit for TXD so that IOMUX won't pull
up/down the pin after turning into tristate. When we use SSI normal mode to
playback monaural audio via I2S signal, there'd be a pulled curve occur to
its signal at the second slot if setting PUE bit for TXD. And it will make
the second channel to play a constant noise. So by keeping the signal level
in the second slot, we can get a constant high level signal (-1) or a low
level one (0).

hpfs: optimize quad buffer loading
HPFS needs to load 4 consecutive 512-byte sectors when accessing the
directory nodes or bitmaps. We can't switch to 2048-byte block size
because files are allocated in the units of 512-byte sectors.
Previously, the driver would allocate a 2048-byte area using kmalloc,
copy the data from four buffers to this area and eventually copy them
back if they were modified.
In the current implementation of the buffer cache, buffers are allocated
in the pagecache. That means that 4 consecutive 512-byte buffers are
stored in consecutive areas in the kernel address space. So, we don't
need to allocate extra memory and copy the content of the buffers there.
This patch optimizes the code to avoid copying the buffers. It checks
if the four buffers are stored in contiguous memory - if they are not,
it falls back to allocating a 2048-byte area and copying data there.

New versions of wine are hammering on the statfs syscall very heavily,
making some games unplayable when they're stored on hpfs, with load
times in minutes.
This should be backported to the stable kernels because it fixes

TI_EDMA fell out of automatically selected options in the multi_v7

The rest is just the result of running 'make multi_v7_defconfig + make
