d281a982c2 soc: ti: replace usage of found with dedicated list iterator variable
To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.

To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean [1].

This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.

1f854536a8 dmaengine: Clarify cyclic transfer residue documentation
The current documentation for the residue reported in a cyclic transfer
case mentions that the reported residue should be relative to the current
period only. However the definition of DMA_RESIDUE_GRANULARITY_SEGMENT
specifies that the residue should be updated after each period for
a cyclic transfer, which is in direct contradiction.

Moreover the pcm_dmaengine common code uses the residue relative to
the whole cyclic buffer size, not one period.

Correct the residue-related documentation to reflect this.

5f77876013 drm: add a check to verify the size alignment
Add a simple check to reject any size not aligned to the
min_page_size.

when size is not aligned to min_page_size, driver module
should handle in their own way either to round_up() the
size value to min_page_size or just to enable WARN_ON().

If we dont handle the alignment properly, we may hit the
following bug, Unigine Heaven has allocation requests for
example required pages are 257 and alignment request is 256.
To allocate the left over 1 page, continues the iteration to
find the order value which is 0 and when it compares with
min_order = 8, triggers the BUG_ON(order < min_order).

v2: add more commit description
v3: remove WARN_ON()

206680c4e4 dma: at_xdmac: fix a missing check on list iterator
The bug is here:
	__func__, desc, &desc->tx_dma_desc.phys, ret, cookie, residue);

The list iterator 'desc' will point to a bogus position containing
HEAD if the list is empty or no element is found. To avoid dev_dbg()
prints a invalid address, use a new variable 'iter' as the list
iterator, while use the origin variable 'desc' as a dedicated
pointer to point to the found element.

STM32_MDMA_CCR bit[8] is used to enable Secure Mode (SM). If this bit is
set, it means that all the channel registers are write-protected. So the
channel is not available for Linux use.

Add stm32_mdma_filter_fn() callback filter and give it to
__dma_request_chan (instead of dma_get_any_slave_channel()), to exclude the
channel if it is marked Secure.

needs the pasid_en bit. Remove system pasid programming on device config

The GPIO port layout on the RTL930x SoC series is reversed compared to
the RTL838x and RTL839x SoC series. Add new port offset calculator
functions to ensure the correct order is used when reading port IRQ
data, and ensure bgpio uses the right byte ordering.

Add the "realtek,rlt9300-gpio", "realtek,otto-gpio" compatible for GPIO
nodes on the RTL930x SoC series. This SoC requires an extra register
range, defining the interrupt CPU mapping registers.

80380f89d0 dmaengine: mediatek-cqdma: Use platform_get_irq() to get the interrupt
platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static
allocation of IRQ resources in DT core code, this causes an issue
when using hierarchical interrupt domains using "interrupts" property
in the node as this bypasses the hierarchical setup and messes up the
irq chaining.

In preparation for removal of static setup of IRQ resource from DT core
code use platform_get_irq().

There are no non-DT users for this driver so interrupt range
(irq_res->start-irq_res->end) is no longer required and with DT we will
be sure it will be a single IRQ resource for each index.

e782f5bad3 Merge branch 'mptcp-next'
Mat Martineau says:

====================
mptcp: Miscellaneous changes for 5.19

Four separate groups of patches here:

Patch 1 optimizes flag checking when releasing mptcp socket locks.

Patches 2 and 3 update the packet scheduler when subflow priorities
change.

Patch 4 adds some pernet helper functions for MPTCP.

Patches 5-8 add diag support for MPTCP listeners, including a selftest.

Check dumping of mptcp listener sockets:

2. filter by sport should return listen sk
3. filter by saddr+sport should return listen sk
4. no filter should return listen sk

4fa39b701c mptcp: listen diag dump support
makes 'ss -Ml' show mptcp listen sockets.

Iterate over the tcp listen sockets and pick those that have mptcp ulp
info attached.

mptcp_diag_get_info() is modified to prefer msk->first for mptcp sockets
in listen state.  This reports accurate number for recv and send queue
(pending / max connection backlog counters).

Sample output:
ss -Mil
State        Recv-Q Send-Q Local Address:Port  Peer Address:Port
LISTEN       0      20     127.0.0.1:12000     0.0.0.0:*

e8887b7161 mptcp: remove locking in mptcp_diag_fill_info
Problem is that listener iteration would call this from atomic context
so this locking is not allowed.

One way is to drop locks before calling the helper, but afaics the lock
isn't really needed, all values are fetched via READ_ONCE().

This patch adds two pm_nl_pernet related helpers, named pm_nl_get_pernet()
and pm_nl_get_pernet_from_msk() to get pm_nl_pernet from 'net' or 'msk'.
Use these helpers instead of using net_generic() directly.

status of any subflow, we need to reset the packet
scheduler status, or the next send could keep using

Reorganize the code to avoid multiple conditionals in the
most common scenarios.
