bc2dc4406c compiler-clang: remove version check for BPF Tracing
bpftrace parses the kernel headers and uses Clang under the hood.

Remove the version check when __BPF_TRACING__ is defined (as bpftrace
does) so that this tool can continue to parse kernel headers, even with
older clang sources.

Fixes: commit 1f7a44f63e ("compiler-clang: add build check for clang 10.0.1")

8c41245872 dt-bindings:iio:adc:renesas,rcar-gyroadc: txt to yaml conversion.
This is a somewhat unusual device, in that it effectively does
spi offload.   That means that it doesn't act as a full SPI
master, but supports some functionality.  As such it supports
a subset of specific SPI ADCs.  There is potential for a future
clash in bindings, but as these are simple devices hopefully that
will not occur.

One addition to this from testing it against existing dts files
was to add a resets property.
This is specified in arch/arm/boot/dts/r8a7791.dtsi
If it's the dtsi that is wrong and not the binding doc, then
we can fix that instead.

4c68e499bb dma-buf: heaps: Skip sync if not mapped
This patch is basically a port of Ørjan Eide's similar patch for ION
 https://lore.kernel.org/lkml/20200414134629.54567-1-orjan.eide@arm.com/

Only sync the sg-list of dma-buf heap attachment when the attachment
is actually mapped on the device.

dma-bufs may be synced at any time. It can be reached from user space
via DMA_BUF_IOCTL_SYNC, so there are no guarantees from callers on when
syncs may be attempted, and dma_buf_end_cpu_access() and
dma_buf_begin_cpu_access() may not be paired.

Since the sg_list's dma_address isn't set up until the buffer is used
on the device, and dma_map_sg() is called on it, the dma_address will be
NULL if sync is attempted on the dma-buf before it's mapped on a device.

Before v5.0 (commit 55897af630 ("dma-direct: merge swiotlb_dma_ops
into the dma_direct code")) this was a problem as the dma-api (at least
the swiotlb_dma_ops on arm64) would use the potentially invalid
dma_address. How that failed depended on how the device handled physical
address 0. If 0 was a valid address to physical ram, that page would get
flushed a lot, while the actual pages in the buffer would not get synced
correctly. While if 0 is an invalid physical address it may cause a
fault and trigger a crash.

In v5.0 this was incidentally fixed by commit 55897af630 ("dma-direct:
merge swiotlb_dma_ops into the dma_direct code"), as this moved the
dma-api to use the page pointer in the sg_list, and (for Ion buffers at
least) this will always be valid if the sg_list exists at all.

But, this issue is re-introduced in v5.3 with
commit 449fa54d68 ("dma-direct: correct the physical addr in
dma_direct_sync_sg_for_cpu/device") moves the dma-api back to the old
behaviour and picks the dma_address that may be invalid.

dma-buf core doesn't ensure that the buffer is mapped on the device, and
thus have a valid sg_list, before calling the exporter's
begin_cpu_access.

a5d2d29e24 dma-buf: heaps: Move heap-helper logic into the cma_heap implementation
Since the heap-helpers logic ended up not being as generic as
hoped, move the heap-helpers dma_buf_ops implementations into
the cma_heap directly.

This will allow us to remove the heap_helpers code in a following
patch.

3812957587 dma-buf: system_heap: Rework system heap to use sgtables instead of pagelists
In preparation for some patches to optmize the system
heap code, rework the dmabuf exporter to utilize sgtables rather
then pageslists for tracking the associated pages.

This will allow for large order page allocations, as well as
more efficient page pooling.

In doing so, the system heap stops using the heap-helpers logic
which sadly is not quite as generic as I was hoping it to be, so
this patch adds heap specific implementations of the dma_buf_ops
function handlers.

74cde1a533 irqchip/gic-v3-its: Unconditionally save/restore the ITS state on suspend
On systems without HW-based collections (i.e. anything except GIC-500),
we rely on firmware to perform the ITS save/restore. This doesn't
really work, as although FW can properly save everything, it cannot
fully restore the state of the command queue (the read-side is reset
to the head of the queue). This results in the ITS consuming previously
processed commands, potentially corrupting the state.

Instead, let's always save the ITS state on suspend, disabling it in the
process, and restore the full state on resume. This saves us from broken
FW as long as it doesn't enable the ITS by itself (for which we can't do
anything).

This amounts to simply dropping the ITS_FLAGS_SAVE_SUSPEND_STATE.

b4fa73358c soc: ti: Fix reference imbalance in knav_dma_probe
The patch fix two reference leak.

  1) pm_runtime_get_sync will increment pm usage counter even it
     failed. Forgetting to call put operation will result in
     reference leak.

  2) The pm_runtime_enable will increase power disable depth. Thus
     a pairing decrement is needed on the error handling path to
     keep it balanced.

We fix it by: 1) adding call pm_runtime_put_noidle or
pm_runtime_put_sync in error handling. 2) adding pm_runtime_disable
in error handling, to keep usage counter and disable depth balanced.
