The TWL6032 has some clock outputs which are controlled like
fixed-voltage regulators, in some drivers for these chips
found in the wild, just the regulator api is abused for controlling
them, so simply use something similar to the regulator functions.
Due to a lack of hardware available for testing, leave out the
TWL6030-specific part of those functions.

tools: ynl-gen: support full range of min/max checks
YNL code gen currently supports only very simple range checks
within the range of s16. Add support for full range of u64 / s64
which is good to have, and will be even more important with uint / sint.

Extend the support to full range of min/max checks.
None of the existing YNL families required complex integer validation.
The support is less than trivial, because we try to keep struct nla_policy
tiny the min/max members it holds in place are s16. Meaning we can only
express checks in range of s16. For larger ranges we need to define
a structure and link it in the policy.

Expand the sockopt test to use also check for io_uring {g,s}etsockopt
commands operations.
This patch starts by marking each test if they support io_uring support
or not.
Right now, io_uring cmd getsockopt() has a limitation of only
accepting level == SOL_SOCKET, otherwise it returns -EOPNOTSUPP. Since
there aren't any test exercising getsockopt(level == SOL_SOCKET), this
patch changes two tests to use level == SOL_SOCKET, they are
"getsockopt: support smaller ctx->optlen" and "getsockopt: read
ctx->optlen".
There is no limitation for the setsockopt() part.
Later, each test runs using regular {g,s}etsockopt systemcalls, and, if
liburing is supported, execute the same test (again), but calling
liburing {g,s}setsockopt commands.
This patch also changes the level of two tests to use SOL_SOCKET for the
following two tests. This is going to help to exercise the io_uring
subsystem:
* getsockopt: read ctx->optlen
* getsockopt: support smaller ctx->optlen

Add support for getsockopt command (SOCKET_URING_OP_GETSOCKOPT), where
level is SOL_SOCKET. This is leveraging the sockptr_t infrastructure,
where a sockptr_t is either userspace or kernel space, and handled as
such.
Differently from the getsockopt(2), the optlen field is not a userspace
pointers. In getsockopt(2), userspace provides optlen pointer, which is
overwritten by the kernel. In this implementation, userspace passes a
u32, and the new value is returned in cqe->res. I.e., optlen is not a
pointer.

At present, we have found that there may be a problem of blurred
screen during fast sleep/resume. The direct cause of the blurred
screen is that the IC does not receive 0x28/0x10. Because of the
particularity of the IC, before the panel enters sleep hid must
stop scanning, as i2c_hid_core_suspend before ili9882t_disable.
If move the ili9882t_enter_sleep_mode function to ili9882t_unprepare,
touch reset will pull low before panel entersleep, which does not meet
the timing requirements.. So in order to solve this problem, the IC
can handle it through the exception mechanism when it cannot receive
0x28/0x10 command. Handling exceptions requires a reset 50ms delay.
Refer to vendor detailed analysis [1].
Ilitek vendor also suggested switching the page before entering sleep to
avoid panel IC not receiving 0x28/0x10 command.
Note: 0x28 is display off, 0x10 is sleep in.

The Starry ILI9882t-based panel should never have been part of the boe
tv101wum driver, it is clearly based on the Ilitek ILI9882t display
controller and if you look at the custom command sequences for the
panel these clearly contain the signature Ilitek page switch (0xff)
commands. The hardware has nothing in common with the other panels
supported by this driver.
Break this out into a separate driver and config symbol instead.
If the placement here is out of convenience for using similar code,
we should consider creating a helper library instead.

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
Two nice cleanups from Brent Lu and Charles Keepax, and one RaptorLake
update.
Feels like an up-tick in regression fixes, mostly for older releases.
The hfsc fix, tcp_disconnect() and Intel WWAN fixes stand out as fairly
clear-cut user reported regressions. The mlx5 DMA bug was causing strife
for 390x folks. The fixes themselves are not particularly scary, tho.
No open investigations / outstanding reports at the time of writing.
Current release - regressions:
- eth: mlx5: perform DMA operations in the right locations,
make devices usable on s390x, again
- sched: sch_hfsc: upgrade 'rt' to 'sc' when it becomes a inner curve,
previous fix of rejecting invalid config broke some scripts
- rfkill: reduce data->mtx scope in rfkill_fop_open, avoid deadlock
- revert "ethtool: Fix mod state of verbose no_mask bitset",
needs more work
Current release - new code bugs:
- tcp: fix listen() warning with v4-mapped-v6 address
Previous releases - regressions:
- tcp: allow tcp_disconnect() again when threads are waiting,
it was denied to plug a constant source of bugs but turns out
.NET depends on it
- eth: mlx5: fix double-free if buffer refill fails under OOM
- revert "net: wwan: iosm: enable runtime pm support for 7560",
it's causing regressions and the WWAN team at Intel disappeared
- tcp: tsq: relax tcp_small_queue_check() when rtx queue contains
a single skb, fix single-stream perf regression on some devices
Previous releases - always broken:
- Bluetooth:
- fix issues in legacy BR/EDR PIN code pairing
- correctly bounds check and pad HCI_MON_NEW_INDEX name
- netfilter:
- more fixes / follow ups for the large "commit protocol" rework,
which went in as a fix to 6.5
- fix null-derefs on netlink attrs which user may not pass in
- tcp: fix excessive TLP and RACK timeouts from HZ rounding
(bless Debian for keeping HZ=250 alive)
- net: more strict VIRTIO_NET_HDR_GSO_UDP_L4 validation, prevent
letting frankenstein UDP super-frames from getting into the stack
- net: fix interface altnames when ifc moves to a new namespace
- eth: qed: fix the size of the RX buffers
- mptcp: avoid sending RST when closing the initial subflow

Pull networking fixes from Jakub Kicinski:
"Including fixes from bluetooth, netfilter, WiFi.
Feels like an up-tick in regression fixes, mostly for older releases.
The hfsc fix, tcp_disconnect() and Intel WWAN fixes stand out as
fairly clear-cut user reported regressions. The mlx5 DMA bug was
causing strife for 390x folks. The fixes themselves are not
particularly scary, tho. No open investigations / outstanding reports
at the time of writing.
Current release - regressions:
- eth: mlx5: perform DMA operations in the right locations, make
devices usable on s390x, again
- sched: sch_hfsc: upgrade 'rt' to 'sc' when it becomes a inner
curve, previous fix of rejecting invalid config broke some scripts
- rfkill: reduce data->mtx scope in rfkill_fop_open, avoid deadlock
- revert "ethtool: Fix mod state of verbose no_mask bitset", needs
more work
Current release - new code bugs:
- tcp: fix listen() warning with v4-mapped-v6 address
Previous releases - regressions:
- tcp: allow tcp_disconnect() again when threads are waiting, it was
denied to plug a constant source of bugs but turns out .NET depends
on it
- eth: mlx5: fix double-free if buffer refill fails under OOM
- revert "net: wwan: iosm: enable runtime pm support for 7560", it's
causing regressions and the WWAN team at Intel disappeared
- tcp: tsq: relax tcp_small_queue_check() when rtx queue contains a
single skb, fix single-stream perf regression on some devices
Previous releases - always broken:
- Bluetooth:
- fix issues in legacy BR/EDR PIN code pairing
- correctly bounds check and pad HCI_MON_NEW_INDEX name
- netfilter:
- more fixes / follow ups for the large "commit protocol" rework,
which went in as a fix to 6.5
- fix null-derefs on netlink attrs which user may not pass in
- tcp: fix excessive TLP and RACK timeouts from HZ rounding (bless
Debian for keeping HZ=250 alive)
- net: more strict VIRTIO_NET_HDR_GSO_UDP_L4 validation, prevent
letting frankenstein UDP super-frames from getting into the stack
- net: fix interface altnames when ifc moves to a new namespace
- eth: qed: fix the size of the RX buffers
- mptcp: avoid sending RST when closing the initial subflow"

...
This patch adds genradix_peek_prev(), genradix_iter_rewind(), and
genradix_for_each_reverse(), for iterating backwards over a generic
radix tree.

When we started spreading new inode numbers throughout most of the 64
bit inode space, that triggered some corner case bugs, in particular
some integer overflows related to the radix tree code. Oops.
