adin: add support for clock output
This patch series adds support for configuring the two clock outputs of adin
1200 and 1300 PHYs. Certain network controllers require an external reference
clock which can be provided by the PHY.
One of the replies to v1 was asking why the common clock framework isn't used.
Currently no PHY driver has implemented providing a clock to the network
controller. Instead they rely on vendor extensions to make the appropriate
configuration. For example ar8035 uses qca,clk-out-frequency - this patchset
aimed to replicate the same functionality.
Finally the 125MHz free-running clock is enabled in the device-tree for
SolidRun i.MX6 SoMs, to support revisions 1.9 and later, where the original phy
has been replaced with an adin 1300.
To avoid introducing new warning messages during boot for SoMs before rev 1.9,
the status field of the new phy node is disabled by default, and will be
enabled by U-Boot on demand.

Since SoM revision 1.9 the PHY has been replaced with an ADIN1300,
add an entry for it next to the original.
As Russell King pointed out, additional phy nodes cause warnings like:
mdio_bus 2188000.ethernet-1: MDIO device at address 1 is missing
To avoid this the new node has its status set to disabled. U-Boot will
be modified to enable the appropriate phy node after probing.
The existing ar8035 nodes have to stay enabled by default to avoid
breaking existing systems when they update Linux only.

Technically the phy also supports a recovered 125MHz clock for

runtime, however Linux does not currently have a toggle for this,
so support is explicitly omitted.

instead of doing it from garbage collector path.
7) Disable register tracking infrastructure, either user-space or

The TCU clock gate on X1000 wasn't requested by the driver and could
be gated automatically later on in boot, which prevents timers from
running and breaks PWM.
Add a workaround to support old device trees that don't specify the

This patch tries to fix permission consistency issue as all other
mainline filesystems.
Since the initial introduction of (posix) fallocate back at the turn of
the century, it has been possible to use this syscall to change the
user-visible contents of files. This can happen by extending the file
size during a preallocation, or through any of the newer modes (punch,
zero, collapse, insert range). Because the call can be used to change
file contents, we should treat it like we do any other modification to a
file -- update the mtime, and drop set[ug]id privileges/capabilities.
The VFS function file_modified() does all this for us if pass it a
locked inode, so let's make fallocate drop permissions correctly.

We use ->buf_pages != 0 to tell if this is a shared buffer ring or a
classic provided buffer group. If we unregister the shared ring and
then attempt to use it, buf_pages is zero yet the classic list head
isn't properly initialized. This causes io_buffer_select() to think
that we have classic buffers available, but then we crash when we try
and get one from the list.
Just initialize the list if we unregister a shared buffer ring, leaving
it in a sane state for either re-registration or for attempting to use
it. And do the same for the initial setup from the classic path.

Currently, when trying to suspend and resume with VirtualPS/2 VMMouse
there is an error message after resuming:
psmouse serio1: vmmouse: Unable to re-enable mouse when reconnecting, err: -6
and the mouse will no longer be operable, requiring full rescan to find a
another driver to use for the port.
This error is due to QEMU still generating PS2 events which the kernel is
not consuming until resume time, where they interfere with mouse
identification and ultimately resulting in an error getting
VMMOUSE_VERSION_ID.
Test scenario:
1) start virtual machine with qemu command "vmport=on"
2) click suspend botton to enter suspend mode
3) resume and observe the error message in the kernel logs
Let's fix this by disabling the vmmouse in its reset handler. This will
notify qemu to stop vmmouse and remove the handler.

Consider CPU, L2 cache, and memory clocks as critical to prevent
them -- and the parent clocks -- from being automatically gated,
since nothing calls clk_get() on these clocks.
Gating the CPU clock hangs the processor, and gating memory makes
external DRAM inaccessible. Normal kernel code can't hope to deal
with either situation so those clocks have to be critical.
The L2 cache is required only if caches are running, and could be
gated if the kernel takes care to flush and disable caches before
gating the clock. There's no mechanism to do this, and probably no
reason to do it, so it's simpler to mark the L2 cache as critical.

request_reinit() is not only ugly as the comment rightfully suggests,
but also unsafe. Even though it is called with osdc->lock held for
write in all cases, resetting the OSD request refcount can still race
with handle_reply() and result in use-after-free. Taking linger ping
as an example:
handle_timeout thread handle_reply thread
down_read(&osdc->lock)
req = lookup_request(...)
...
finish_request(req) # unregisters
up_read(&osdc->lock)
__complete_request(req)
linger_ping_cb(req)
# req->r_kref == 2 because handle_reply still holds its ref
down_write(&osdc->lock)
send_linger_ping(lreq)
req = lreq->ping_req # same req
# cancel_linger_request is NOT
# called - handle_reply already
# unregistered
request_reinit(req)
WARN_ON(req->r_kref != 1) # fires
request_init(req)
kref_init(req->r_kref)
# req->r_kref == 1 after kref_init
ceph_osdc_put_request(req)
kref_put(req->r_kref)
# req->r_kref == 0 after kref_put, req is freed
<further req initialization/use> !!!
This happens because send_linger_ping() always (re)uses the same OSD
request for watch ping requests, relying on cancel_linger_request() to
unregister it from the OSD client and rip its messages out from the
messenger. send_linger() does the same for watch/notify registration
and watch reconnect requests. Unfortunately cancel_request() doesn't
guarantee that after it returns the OSD client would be completely done
with the OSD request -- a ref could still be held and the callback (if
specified) could still be invoked too.
The original motivation for request_reinit() was inability to deal with
allocation failures in send_linger() and send_linger_ping(). Switching
to using osdc->req_mempool (currently only used by CephFS) respects that
and allows us to get rid of request_reinit().
