b9f34757db usb: sunxi: access ahb_reset0_cfg in CCM using its offset
struct sunxi_ccm_reg doesn't have ahb_reset0_cfg on sun4i and sun5i,
thus compilation fails with:

drivers/usb/host/ohci-sunxi.c:96:26: error: 'struct sunxi_ccm_reg' has
no member named 'ahb_reset0_cfg'

Access this reg using its offset to fix this issue.

Fixes commit 1ed9c1118 ("usb: sunxi: ehci: get rid of ifdefs")

f8c987f8f1 lib: Add hexdump
Often during debugging session it's very interesting to see
what data we were dealing with. For example what we write or read
to/from memory or peripherals.

This change introduces functions that allow to dump binary
data with one simple function invocation like:
------------------->8----------------
print_hex_dump_bytes("", DUMP_PREFIX_OFFSET, buf, len);
------------------->8----------------

which gives us the following:

afa314d3a3 rockchip: xhci: remove DTS parsing for PHY (which is unused)
The xhci wrapper-driver for Rockchip searches the DTS to find its
child node compatbile with 'rockchip,rk3399-usb3-phy' to retrieve the
base-address of the PHY.  However, this is currently broken (and
always has been), returning NULL.  However, the (wrongly) retrieved
base-address is never used.

We thus remove this code for now.

eaaefb066c usb: xhci: Fix config fail of FS hub behind a HS hub with MTT
If a full speed hub connects to a high speed hub which supports MTT,
the MTT field of its slot context will be set to 1 when xHCI driver
setups an xHCI virtual device in xhci_setup_addressable_virt_dev().
Once usb core fetch its hub descriptor, and need to update the xHC's
internal data structures for the device, the HUB field of its slot
context will be set to 1 too, meanwhile MTT is also set before, this
will cause configure endpoint command fail. In the case, we should
clear MTT to 0 for full speed hub according to section 6.2.2.

This keeps in sync with Linux kernel commit:

793c819c6e usb: xhci: Set accurate add context flags when updating hub attributes
If a USB 3.0 hub is plugged into the root port of the xHC, the xHCI
driver will issue a 'Configure Endpoint' command to the xHC for it
to update its internal data structure for this hub device. The hub
attributes are in the slot context so we need tell xHC to update the
slot context by setting the add context flags of the input control
context to only cover the slot context.

At present the add context flags is or'ed with the slot context bit,
but it should really be accurately set to the slot context, as the
variable that holds the value of the add context flags comes from
whatever was set in the last command execution, which may contain
additional contexts that 'Configure Endpoint' command should not
touch. Some xHC implementations like x86 don't complain such, but
it was observed on Renesas RCar Gen3 platform that the RCar xHC
complains with a 'TRB error' completion codes as the response.

To address that situation we discussed on the list moving to

This patch switches over to generic_set_bit to maintain consistency between

5ac73f6879 usb: f_mass_storage: Fix set_bit and clear_bit usage
Compiling the f_mass_storage driver for an x86 target results in a
compilation error as set_bit and clear_bit are provided by bitops.h

Looking at the provenance of the current u-boot code and the git change
history in the kernel, it looks like we have a local copy of set_bit and
clear_bit as a hold-over from porting the Linux driver into u-boot.

These days __set_bit and __clear_bit are optionally provided by an arch and
can be used as inputs to generic_bit_set and generic_bit_clear.

This patch switches over to generic_set_bit and generic_clear_bit to
accommodate.

Tested on i.MX WaRP7 and Intel Edison

f739fcd831 SPDX: Convert a few files that were missed before
As part of the main conversion a few files were missed.  These files had
additional whitespace after the '*' and before the SPDX tag and my
previous regex was too strict.  This time I did a grep for all SPDX tags
and then filtered out anything that matched the correct styles.

8c1de5e08b regmap: clean up regmap allocation
Putting zero length array at the end of struct is a common technique
to embed arbitrary length of members.  There is no good reason to let
regmap_alloc_count() branch by "if (count <= 1)".

As far as I understood the code, regmap->base is an alias of
regmap->ranges[0].start, but it is not helpful but make the code
just ugly.

Rename regmap_alloc_count() to regmap_alloc() because the _count
suffix seems pointless.

4549e789c1 SPDX: Convert all of our multiple license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document.  Note that parenthesis are
allowed so when they were used before we continue to use them.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.
