In some situations, we need vbus level which lower than vbus valid
as wakeup source, eg, at the OTG certification test, the valid bus
level for b device is from 4.0v to 6.0v.

The commit c01cdab21b1e3cc045f40f29ca0d9292d238ffda introduced a different
configuration for rotation case in PxP driver, that is, it requires the rotated
width and height value. Thus EPDC driver, the user of PxP driver should also
adjust accordingly.

USB: gadget: mtp: Fix hang in ioctl(MTP_RECEIVE_FILE) for
WritePartialObject
In receive_file_work, we now queue reads with length rounded up to
max packet size rather than mtp_rx_req_len.
Otherwise the read request will never complete.

The output image area bounds check should be moved to
where the 'l', 't', 'w' and 'h' are finalized to avoid
the drect area beyond the maximum fb display area which
may cause overflow issue when calculating the PXP PS LRC

The FEC modules used on i.MX28 and newer have a register to tune the MDIO
output hold time that should be at least 10 ns. Up to now this value was not
explicitly set and so resulted in less hold time if the fec clock was
faster than 100 MHz.
This was noticed on an i.MX28 machine that uses an input clock of ~150
Mhz which resulted in unreliable communication with a Marvell switch.

When the driver is removed (e.g. using unbind through sysfs), the
clocks get disabled twice, once on fec_enet_close and once on
fec_drv_remove. Since the clocks are enabled only once, this leads
to a warning:
WARNING: CPU: 0 PID: 402 at drivers/clk/clk.c:992 clk_core_disable+0x64/0x68()
Remove the call to fec_enet_clk_enable in fec_drv_remove to balance
the clock enable/disable calls again. This has been introduce by
e8fcfcd5684a ("net: fec: optimize the clock management to save power").

Currently we find that if a usdhc is choosed to boot system, then ROM
code will set the burst length enable bit of this usdhc as 0.
This will make performance drop a lot if this usdhc's burst length is
16. So this patch set back the burst_length_enable bit as 1, which is
the default value, and means burst length is enabled for INCR.

currently we set burst length from 8 to 16 in our usdhc driver, but
we find if the burst length is 16, the SD3.0 performance on
i.MX6Q-sabreauto and i.MX6QP-sabreauto board will drop a lot.
for TOSHIBA 16GB SDR104 card,
if burst length is 16, the peformance on these two boards is:
read: 19.4MB/s, write: 13.2MB/s
when burst length is 8, the performance on these two boards is:
read: 63MB/s, write: 25.4MB/s
other boards like i.MX6sl-evk, i.MX6sx-sdb and i.MX7D-12x12-arm2
has no this issue.
The root cause still not find on these two boards. So this patch
just change the burst length to 16 for i.MX7d, all i.MX6 series
will remain 8.

Rather than using the streaming API, use the coherent allocator to
provide this memory, thereby eliminating cache flushing of it each
time we map and unmap it. This results in a 7.5% increase in
transfer speed with a UHS-1 card operating in 3.3v mode at a clock
of 49.5MHz.

parent on
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.

In a corner case: system suspend with usb device connected on OTG port, then
remove usb device and connect OTG port to PC, and then resume the system,
OTG cannot be enumrated by PC. Reason is there is no BSV irq generated after
resume, so b_sess_vld cannot be updated and otg fsm state keeps in b_idle state
with vbus on, this patch force a update of b_sess_vld flag according to OTGSC
BSV status.
