d929241225 media: mtk-vcodec: add missing put_device() call in mtk_vcodec_init_dec_pm()
[ Upstream commit 5d4fa2c50125c9cda9e380d89268757cc5fa743d ]

if of_find_device_by_node() succeed, mtk_vcodec_init_dec_pm() doesn't have
a corresponding put_device(). Thus add jump target to fix the exception
handling for this function implementation.

22ec701910 media: tm6000: Fix sizeof() mismatches
[ Upstream commit a08ad6339e0441ca12533969ed94a87e3655426e ]

The are two instances of sizeof() being used incorrectly. The
sizeof(void *) is incorrect because urb_buffer is a char ** pointer,
fix this by using sizeof(*dev->urb_buffer).  The sizeof(dma_addr_t *)
is incorrect, it should be sizeof(*dev->urb_dma), which is a dma_addr_t
and not a dma_addr_t *.  This errors did not cause any issues because
it just so happens the sizes are the same.

Addresses-Coverity: ("Sizeof not portable (SIZEOF_MISMATCH)")

commit 9c60cc797cf72e95bb39f32316e9f0e5f85435f9 upstream.

SPI bus number must be assigned dynamically for each device, otherwise it

bac63f1239 media: vb2: set cache sync hints when init buffers
We need to set ->need_cache_sync_on_prepare and
->need_cache_sync_on_finish when we initialize vb2 buffer.

Currently these flags are set/adjusted only in V4L2's
vb2_queue_or_prepare_buf(), which means that for the code
paths that don't use V4L2 vb2 will always tell videobuf2
core to skip ->prepare() and ->finish() cache syncs/flushes.
Fix this by setting cache sync hints for new buffers; except
VB2_MEMORY_DMABUF buffers, for which DMA exporter syncs
caches.

024e01dead media: pulse8-cec: fix duplicate free at disconnect or probe error
Commit 601282d65b ("media: pulse8-cec: use adap_free callback") used
the adap_free callback to clean up on disconnect. What I forgot was that
in the probe it will call cec_delete_adapter() followed by kfree(pulse8)
if an error occurs. But by using the adap_free callback,
cec_delete_adapter() is already freeing the pulse8 struct.

This wasn't noticed since normally the probe works fine, but Pulse-Eight
published a new firmware version that caused a probe error, so now it
hits this bug. This affects firmware version 12, but probably any
version >= 10.

Commit aa9eda7612 ("media: pulse8-cec: close serio in disconnect, not
adap_free") made this worse by adding the line 'pulse8->serio = NULL'
right after the call to cec_unregister_adapter in the disconnect()
function. Unfortunately, cec_unregister_adapter will typically call
cec_delete_adapter (unless a filehandle to the cec device is still
open), which frees the pulse8 struct. So now it will also crash on a
simple unplug of the Pulse-Eight device.

With this fix both the unplug issue and a probe() error situation are
handled correctly again.

It will still fail to probe() with a v12 firmware, that's something
to look at separately.

1d2b2a6d8c media: vidtv: fix the network ID range
As defined at ETSI TS 101 162, original network IDs up to 0xfebf
are reserved for registration at dvb.org.

Let's use, instead, an original network ID at the range
0xff00-0xffff, as this is for private temporary usage.

As the same value is also used for the network ID,
the range 0xff01-0xffff also fits better, as values
lower than that depend if the network is used for
satellite, terrestrial, cable of CI.

While here, move the TS ID to the bridge code, where it
is used, and change its value, as it was identical to
the value previously used by network ID. While we could
keep the same value, let's change it, just to make easier
to check for the new code while reading it with DVB tools
like dvbinspector.

After revisit the OPP part of the code I found that OPP pmdomain
is detached with direct call to dev_pm_domain_detach instead of
OPP wraper for detaching pmdomains with OPP table. Correct this
by calling the OPP dev_pm_opp_detach_genpd.

2da185d6fe media: mtk-vcodec: fix build breakage when one of VPU or SCP is enabled
The addition of MT8183 support added a dependency on the SCP remoteproc
module. However the initial patch used the "select" Kconfig directive,
which may result in the SCP module to not be compiled if remoteproc was
disabled. In such a case, mtk-vcodec would try to link against
non-existent SCP symbols. "select" was clearly misused here as explained
in kconfig-language.txt.

Replace this by a "depends" directive on at least one of the VPU and
SCP modules, to allow the driver to be compiled as long as one of these
is enabled, and adapt the code to support this new scenario.

Also adapt the Kconfig text to explain the extra requirements for MT8173
and MT8183.

The underlying cause is that the while condition is wrong. It should be:

(status < 0 || wait_cmd) && (retry_count < DRXK_MAX_RETRIES)

'wait_cmd' is only valid if '!(status < 0)'.

which is rather confusing and can cause gcc warnings:

s5k5baf.c: In function 's5k5baf_load_setfile.isra':
s5k5baf.c:390:13: warning: array subscript 65535 is outside the bounds of an interior zero-length array 'struct <anonymous>[0]' [-Wzero-length-bounds]
  390 |   if (f->seq[i].offset + d <= end)
      |       ~~~~~~^~~

It turns out that 'data[]' is used in only one place and it can
easily be replaced by &fw->seq[0].id and 'seq[0]' can be replaced by
'seq[]'.

This is both more readable and solved that warnings.

ff1c9223b7 media: rc: gpio-ir-recv: add QoS support for cpuidle system
GPIO IR receive is much rely on interrupt response, uneven interrupt
latency will lead to incorrect timing, so the decoder fails to decode
it. The issue is particularly acute on some systems which support
cpuidle, not all, dynamically disable and enable cpuidle can solve this
problem to a great extent.

However, there is a downside to this approach, the measurement of header
on the first frame may incorrect. Test on i.MX8M serials, when enable
cpuidle, interrupt latency could be about 500us.

With this patch:
1. has no side effect on non-cpuidle system, even runtime pm api won't
be invoked to avoid a bunch of pm busy work for devices that do not need
it, including spinlocks, ktime, etc.
2. latency is still much longer for the first gpio interrupt on cpuidle
system, so the first frame may not be decoded. Generally, RC would transmit
multiple frames at once press, we can sacrifice the first frame.
3. add "linux,autosuspend-period" property in device tree if you also
suffer this cpuidle issue.

7dae2aaaf4 media: ti-vpe: Fix a missing check and reference count leak
pm_runtime_get_sync() increments the runtime PM usage counter even
when it returns an error code, causing incorrect ref count if
pm_runtime_put_noidle() is not called in error handling paths.
And also, when the call of function vpe_runtime_get() failed,
we won't call vpe_runtime_put().
Thus call pm_runtime_put_noidle() if pm_runtime_get_sync() fails
inside vpe_runtime_get().

Calling pm_runtime_get_sync increments the counter even in case of
failure, causing incorrect ref count if pm_runtime_put is not
called in error handling paths. Thus replace the jump target
"err_release_buffers" by "err_pm_putw".
