Qoriq and related devices allow reading out state of GPIO set as output.
However, currently on driver's init, all outputs are configured as driven
low. So, any changes to GPIO confiuration will drive all pins (configured
as output) as output-low.
This patch latches state of output GPIOs before any GPIO configuration
takes place. This preserves any output settings done prior to loading
the driver (for example, by u-boot).

Add support for the BlueField-3 SoC GPIO driver.
This driver configures and handles GPIO interrupts. It also enables a user
to manipulate certain GPIO pins via libgpiod tools or other kernel drivers.
The usables pins are defined via the "gpio-reserved-ranges" property.

in that case as object files tc_bindings.o and tc_encap_actions.o
are not built, so the calls to them from ef100_netdev_event and

Intel Barlow Ridge is the first USB4 v2 controller from Intel. The
controller exposes standard USB4 PCI class ID in typical configurations,
however there is a way to configure it so that it uses a special class
ID to allow using s different driver than the Windows inbox one. For
this reason add the Barlow Ridge PCI ID to the Linux driver too so that
the driver can attach regardless of the class ID.

USB4 v2 added a bit that can be used to reset the host router so we use
this to trigger reset when the driver probes. This will reset the
already connected topology as well but doing this simplifies things a

a module parameter to prevent this in case of problems.

The current implementation allocates page-sized rx buffers.
As traffic may consist of different types and sizes of packets,
in various cases, buffers are not fully used.
This change (Dynamic RX Buffers - DRB) uses part of the allocated rx
page needed for the incoming packet, and returns the rest of the
unused page to be used again as an rx buffer for future packets.
A threshold of 2K for unused space has been set in order to declare
whether the remainder of the page can be reused again as an rx buffer.
As a page may be reused, dma_sync_single_for_cpu() is added in order
to sync the memory to the CPU side after it was owned by the HW.
In addition, when the rx page can no longer be reused, it is being
unmapped using dma_page_unmap(), which implicitly syncs and then
unmaps the entire page. In case the kernel still handles the skbs
pointing to the previous buffers from that rx page, it may access
garbage pointers, caused by the implicit sync overwriting them.
The implicit dma sync is removed by replacing dma_page_unmap() with
dma_unmap_page_attrs() with DMA_ATTR_SKIP_CPU_SYNC flag.
The functionality is disabled for XDP traffic to avoid handling
several descriptors per packet.

Pull regmap fix from Mark Brown:
"Another fix for the maple tree cache, Takashi noticed that unlike
other caches the maple tree cache didn't check for read only registers
before trying to sync which would result in spurious syncs for read
only registers where we don't have a default.
This was due to the check being open coded in the caches, we now check
in the shared 'does this register need sync' function so that is fixed
for this and future caches"

This seems to have existed for ever but is now more apparant after
commit 9bff18d13473 ("drm/ttm: use per BO cleanup workers")
My analysis: two threads are running, one in the irq signalling the
fence, in dma_fence_signal_timestamp_locked, it has done the
DMA_FENCE_FLAG_SIGNALLED_BIT setting, but hasn't yet reached the
callbacks.
The second thread in nouveau_cli_work_ready, where it sees the fence is
signalled, so then puts the fence, cleanups the object and frees the
work item, which contains the callback.
Thread one goes again and tries to call the callback and causes the
use-after-free.
Proposed fix: lock the fence signalled check in nouveau_cli_work_ready,
so either the callbacks are done or the memory is freed.

Fix a possible memory leak in __stmmac_open when stmmac_init_phy fails.
It's also needed to free everything allocated by stmmac_setup_dma_desc
and not just the dma_conf struct.
Drop free_dma_desc_resources from __stmmac_open and correctly call
free_dma_desc_resources on each user of __stmmac_open on error.
