This is because set_fmt ops maybe called when PD is off,
and in such case, regmap_ops will lead system hang.
enale PD before doing regmap_ops.

invalidate the BTB on CPUs that are known to be affected when taking

In order to avoid aliasing attacks against the branch predictor,
some implementations require to invalidate the BTB when switching
from one user context to another.
For this, we reuse the existing implementation for Cortex-A8, and
apply it to A9, A12 and A17.

Add constants and callback functions for the dwmac on px30 soc.
The base structure is the same, but registers and the bits in
them moved slightly, and add the clk_mac_speed for the select
of mac speed.

The default value of the max_transfer_size is only 65535,
but according to the field of PktSizeWidth in GHWCFG3, the
otg controller on rockchip platforms can support max 512KB
transfer size. So we increase the otg max_transfer_size to
128KB, it can help to avoid dividing into two hardware
transmissions if the usb device class driver(e.g. f_mtp.c)
request to transfer more than 65535 Bytes data in a single
usb request.

If there is more data in the request than we could fit into
a single hardware request, then check both of the following
conditions:
- ep->dwc_ep.xfer_len < ep->dwc_ep.total_len;
- deptsiz.b.xfersize == 0;
If ep->dwc_ep.xfer_len < ep->dwc_ep.total_len and deptsiz.b.xfersize
isn't zero, it means that we have received a short packet from
host, then we shouldn't setup transfer for next portion of
data.
This patch can fix the following issue:
Use MTP to transfer more than 4GB single file from PC to RK3368
tablet base on the follow conditions:
- Increase the default Tx/Rx buf size to 64K or more in f_mtp.c
- Set the core_params->max_transfer_size to 65535;
Without this patch, it will fail to transfer the file at the end
because the f_mtp driver is waiting for a short packet to signal
EOF for file sizes > 4 gig, but the dwc2 driver doesn't handle
the short packet.

For the hardware bug of RK3288 OHCI, we use commit cfe6f1dd57
("usb: ehci: add rockchip relinquishing port quirk support") to fix
it previously. However, it have been ineffective after upstream commit
94c43b9897 ("USB: Check for dropped connection before switching to
full speed") was merged due to the condition of relinquishing port was
changed.
This patch adds an additional condition for the previous commit to ensure
no relinquish port quirk can take effect for RK3288 EHCI.
