musb currently uses a wrapper driver that binds on the parent device of
the actual musb devices to manage the differentiation between gadget and
host modes. However in the upstream devicetree this parent devicetree
node can not be used to match the wrapper driver.
To be able to probe the musb devices in host/gadget mode directly, this
series introduces support for returning -ENODEV in bind functions
resulting in iterating the remaining drivers potentially binding to
other drivers that match the compatible.

The loop in lists_bind_fdt uses an indented style for log messages
within the loop and normal messages for errors that lead to the exit of
the function. Due to the change of the previous patch that adds support
for continuation on -ENODEV returned by bind, the log message should be
indented.

Currently once a driver matched the compatible string of a device, other
drivers are ignored. If the first matching driver returns -ENODEV, no
other possibly matching drivers are iterated with that compatible of the
device. Instead the next compatible in the list of compatibles is
selected, assuming only one driver matches one compatible at a time.
To be able to use the bind function to return -ENODEV and continue
matching other drivers with the same compatible, move the for loop a bit
to continue the for loop after -ENODEV was returned. The loop had to be
adjusted a bit to still support the 'drv' argument properly. Some
simplifications were done as well.
The modification will only add additional loop iterations if -ENODEV is
returned. Otherwise the exit and continue conditions for the loop stay
the same and do not cause any additional iterations and should not
impact performance.
This is required for ti-musb-host and ti-musb-peripheral which both
match on the same device but differ based on the dr_mode DT property.
Depending on this property, the driver is either UCLASS_USB or
UCLASS_USB_GADGET_GENERIC. By checking the DT property in the bind
function and returning -ENODEV the other driver can probe instead.

When aborting a Transfer Descriptor (TD), the xHCI driver updates the
device dequeue pointer by converting the virtual enqueue TRB pointer
into a DMA address.
Previously, the code OR-ed the ring's Dequeue Cycle State (DCS) bit into
the virtual TRB pointer before passing it to xhci_trb_virt_to_dma().
This produced an unaligned virtual address (e.g. ending in 0x...1).
Inside xhci_trb_virt_to_dma(), the offset calculation:
segment_offset = trb - seg->trbs;
operated on this unaligned pointer, resulting in an incorrect TRB index.
In wraparound cases, this caused the bounds check to fail and the
function to return 0.
As a result, a SET_DEQ_PTR command was issued with a DMA address of 0x0,
leading to controller hangs and transfer timeouts, most commonly when
aborting TDs near the end of a ring segment (e.g. index 63).
Fix this by translating the aligned virtual TRB pointer to a DMA address
first, and only then applying the DCS bit to the resulting physical
address.

Pass the unmapped parent ID when setting parent for mux clocks.
For technical reasons, some Mediatek clock driver have a mapping between
the clock IDs used in the devicetree and ID used in the generic clock
framework.
The mtk_clk_mux_set_parent() function is comparing the passed mapped
parent ID against the unmapped IDs in the chip-specific data structures.
Before this change, we were passing the mapped parent ID. When there is
a mapping, this resulted in buggy behavior (usually just incorrectly
failing to find a match and returning an error). We need to pass the
unmapped ID of the parent clock instead for the matching to work
correctly.
Since the reverse lookup is a bit verbose, a helper function is added to
keep the code clean.

Therefore, this error should not be propagated.

- sa8775p clock fixes
- support for "flattened" dwc3 DT that recently landed upstream for

Qualcomm devicetrees are moving away from having a glue node with dwc3
as a subnode and now may just have a single flattened node.
Rockchip already have a glue_get_ctrl_dev op which returns the node for
the glue device itself, commonise this and reuse it for the new Qualcomm
node.
Lastly adjust the qscratch base address since it now requires an offset

define the different possible panels.
To make our work easier, create a compatible way of fetching and
defining these modes in u-boot. get_modes() fetches the available modes
from the panel driver. The get_display_timing() call maps the

between dwc3 and the USB2/USB3 PHY and reset-controller for USB role

To keep USB working as before when the nodes still carried "snps,dwc3"
as compatible add "apple,t8103-dwc3" to the of match table. Eventually
it is probably advisable to add a dwc3-apple glue driver and write code
