This patch fixup that the wrong position when dma desc status
is DONE. even if the desc status is DONE, it is still able to
get the position from the dma driver. so, just remove the judgement.

This patch adds needed nodes for trust in rk3288-linux:
1.Add psci v1.0 support to call into secure world
through psci APIs.
2.Use non-secure dmac instead of secure one.
3.Use new efuse compatible to match secure interface
when kernel is in no-secure mode.

The rk3288 also has one function that can be routed to one of two pins,
the hdmi cec functionality can use either gpio7c0 or gpio7c7.
So add the route switching support for it.

The Kconfig currently controlling compilation of this code is:
drivers/pinctrl/Kconfig:config PINCTRL_ROCKCHIP
drivers/pinctrl/Kconfig: bool
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.
Note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

When building with 'make W=1', we get harmless warnings about
five drivers in drivers/pinctrl, which all contain a copy of
the same line:
drivers/pinctrl/freescale/pinctrl-imx1-core.c:160:1: error: 'inline' is not at beginning of declaration [-Werror=old-style-declaration]
This replaces the somewhat nonstandard 'static const inline'
with 'static inline const', which has the same meaning but
does not cause this warning.

If isoc split in transfer with no data (the length of DATA0
packet is zero), we can't simply return immediately. Because
the DATA0 can be the first transaction or the second transaction
for the isoc split in transaction. If the DATA0 packet with no
data is in the first transaction, we can return immediately.
But if the DATA0 packet with no data is in the second transaction
of isoc split in transaction sequence, we need to increase the
qtd->isoc_frame_index and giveback urb to device driver if needed,
otherwise, the MDATA packet will be lost.
A typical test case is that connect the dwc2 controller with an
usb hs Hub (GL852G-12), and plug an usb fs audio device (Plantronics
headset) into the downstream port of Hub. Then use the usb mic
to record, we can find noise when playback.
In the case, the isoc split in transaction sequence like this:
- SSPLIT IN transaction
- CSPLIT IN transaction
- MDATA packet (176 bytes)
- CSPLIT IN transaction
- DATA0 packet (0 byte)
This patch use both the length of DATA0 and qtd->isoc_split_offset
to check if the DATA0 is in the second transaction.

The commit 3bc04e28a0 ("usb: dwc2: host: Get aligned DMA in
a more supported way") rips out a lot of code to simply the
allocation of aligned DMA. However, it also introduces a new
issue when use isoc split in transfer.
In my test case, I connect the dwc2 controller with an usb hs
Hub (GL852G-12), and plug an usb fs audio device (Plantronics
headset) into the downstream port of Hub. Then use the usb mic
to record, we can find noise when playback.
It's because that the usb Hub uses an MDATA for the first
transaction and a DATA0 for the second transaction for the isoc
split in transaction. An typical isoc split in transaction sequence
like this:
- SSPLIT IN transaction
- CSPLIT IN transaction
- MDATA packet
- CSPLIT IN transaction
- DATA0 packet
The DMA address of MDATA (urb->dma) is always DWORD-aligned, but
the DMA address of DATA0 (urb->dma + qtd->isoc_split_offset) may
not be DWORD-aligned, it depends on the qtd->isoc_split_offset (the
length of MDATA). In my test case, the length of MDATA is usually
unaligned, this cause DATA0 packet transmission error.
This patch use kmem_cache to allocate aligned DMA buf for isoc
split in transaction. Note that according to usb 2.0 spec, the
maximum data payload size is 1023 bytes for each fs isoc ep,
and the maximum allowable interrupt data payload size is 64 bytes
or less for fs interrupt ep. So we set the size of object to be
1024 bytes in the kmem cache.
