Allocate usb otg descriptor and initialize it according to gadget's otg
capabilities, if usb_otg_caps is not set, keep settings as current gadget
drivers. With this 2 new interfaces, gadget can use usb_otg_descriptor
for OTG 1.x, and usb_otg20_descriptor for OTG 2.0 or above, and otg
features can be decided by the combination of usb hardware property
and driver config.

When temperature >= the 'critical_trip' temperature, the common
framework code will call 'orderly_poweroff' function to power off
the system. During the power off procedure the thermal framework
will go on polling the temp, this will lead to recall the
'orderly_poweroff' again. In the first poweroff flow, some system
resource has been freezed, then if the secondary 'orderly_poweroff'
frees the resource again, it will lead to kernel dump.

During the read of NOR, the kernel actually calls the inline_map_copy_from()
to read the data out. And inline_map_copy_from() will use the memcpy_fromio()
to do the real job.
The memcpy_fromio macro maps _memcpy_fromio() in the current code.
But the _memcpy_fromio() will use readb() to do the copy work one byte
by one byte. This makes the read performance of NOR very slow(about 2~3MB/s).
A similiar discussion could be found in:
http://lists.infradead.org/pipermail/linux-arm-kernel/2009-November/003860.html
This patch replace the memcpy_fromio with memcpy which is optimized by the
kernel.

CAAM only has a single clock in i.mx7d. Logic was added to initialize only the
single clock.
The Secure Memory registers moved in CAAM era included in i.mx7d. This required
changes to support access to two different versions of the register map. The
registers are access through a data structure that overlay the register region.
Two new Secure Memory register structures were created to support the different
versions. Logic was also added to determine which version is implemented based on
the CAAM era, and access functions were added to support register access to the
Secure Memory Command and Status registers.

The i.MX6QP IOMUX_GPR5 PRE_PRG_SEL0/1 fields control the PRE/PRG muxing.
The muxing could be described by the following table.
------------------------------------------------------------------
|\ | PRG0/IPU0 | PRG1/IPU1 |
| mux |-----------------------------------------------------------|
| \ |ch0/ch23 |ch1/ch27 |ch2/ch28 |ch0/ch23 |ch1/ch27 |ch2/ch28 |
|------------------------------------------------------------------|
| PRE0 | fixed | n/a | n/a | n/a | n/a | n/a |
|------------------------------------------------------------------|
| PRE1 | n/a | A(2b'00)| A(2b'01)| n/a | A(2b'10)| A(2b'11)|
|------------------------------------------------------------------|
| PRE2 | n/a | B(2b'00)| B(2b'01)| n/a | B(2b'10)| B(2b'11)|

| PRE3 | n/a | n/a | n/a | fixed | n/a | n/a |
------------------------------------------------------------------
(Note - A: GPR5 bit12-13, B: GPR5 bit14-15)
We should bind PRG[x] channel[y] with IPU[x] channel[y+26] statically
instead of dynamically, where x=0or1, y=1or2. Also, the values for A/B
cannot be the same due to a SoC design requirement(even if one of the
PRE1/PRE2 is disabled, the two values cannot be the same). This patch
fixes the PRE/PRG muxing logic.

On Freescale i.MX7D platform, all clocks operations, including enable/disable,
rate change and re-parent, requires its parent clock on.
Current clock core can not support it well.
This patch introduce a new flag CLK_SET_PARENT_ON to handle this special case
in clock core that enable its parent clock firstly for each operation and disable
it later after operation complete.
The most special case is for set_parent() operation which requires both parent,
old one and new one, to be enabled at the same time during the operation.
