The Techwell video decoder supports PAL, NTSC standards and
has a parallel BT.656 output interface.
This commit adds support for this device, with basic support
for NTSC and PAL, along with brightness and contrast controls.
The TW9900 is capable of automatic standard detection. This
driver is implemented with support for PAL and NTSC
autodetection.

media: rkisp1: resizer: Stop manual allocation of v4l2_subdev_state
Supported media bus codes on the resizer sink pad are identical to the
ISP source pad. The .enum_mbus_code() handler thus delegates the
enumeration to the ISP's operation. This is problematic for two
reasons:
- Format enumeration on the ISP source pad is dependent on the format
configured on the ISP sink pad for the same subdev state (TRY or
ACTIVE), while format enumeration on the resizer sink pad should
return all formats supported by the resizer subdev, regardless of the
ISP configuration.
- Delegating the operation involves creating a fake v4l2_subdev_state on
the stack to pass to the ISP .enum_mbus_code() handler. This gets in
the way of evolution of both the ISP enumeration handler and, more
generally, the V4L2 subdev state infrastructure.
Fix those two issues by implementing format enumeration manually for the
resizer.

media: rkisp1: Fix IRQ disable race issue
In rkisp1_isp_stop() and rkisp1_csi_disable() the driver masks the
interrupts and then apparently assumes that the interrupt handler won't
be running, and proceeds in the stop procedure. This is not the case, as
the interrupt handler can already be running, which would lead to the
ISP being disabled while the interrupt handler handling a captured
frame.
This brings up two issues: 1) the ISP could be powered off while the
interrupt handler is still running and accessing registers, leading to
board lockup, and 2) the interrupt handler code and the code that
disables the streaming might do things that conflict.
It is not clear to me if 2) causes a real issue, but 1) can be seen with
a suitable delay (or printk in my case) in the interrupt handler,
leading to board lockup.

In theory this should work fine, but in real life we have device bugs.
The Ali Corp. Newmine Camera (0402:8841) exposes four alternate

Switch to using the first best alternate setting when multiple are

media: videobuf2: request more buffers for vb2_read
The vb2 read support requests 1 buffer, leaving it to the driver
to increase this number to something that works.
Unfortunately, drivers do not deal with this reliably, and in fact
this caused problems for the bttv driver and reading from /dev/vbiX,
causing every other VBI frame to be all 0.
Instead, request as the number of buffers whatever is the maximum of
2 and q->min_buffers_needed+1.
In order to start streaming you need at least q->min_buffers_needed
queued buffers, so add 1 buffer for processing. And if that field
is 0, then choose 2 (again, one buffer is being filled while the
other one is being processed).
This certainly makes more sense than requesting just 1 buffer, and
the VBI bttv support is now working again.
It turns out that the old videobuf1 behavior of bttv was to allocate
8 (video) and 4 (vbi) buffers when used with read(). After the vb2
conversion that changed to 2 for both. With this patch it is 3, which
is really all you need.

media: qcom: camss: Flag VFE-lites to support more VFEs
Some platforms such as SC7280 have three VFEs and two VFE-lites. Current
code has hard-coded two as the maximum number of VFEs. Remove the
hard-coded maximum number of VFEs to handle all possible combinations of

media: qcom: camss: Add support for named power-domains
Right now we use fixed indexes to assign power-domains, with a
requirement for the TOP GDSC to come last in the list.
Adding support for named power-domains means the declaration in the dtsi
can come in any order.
After this change we continue to support the old indexing - if a SoC
resource declaration or the in-use dtb doesn't declare power-domain names
we fall back to the default legacy indexing.
From this point on though new SoC additions should contain named
power-domains, eventually we will drop support for legacy indexing.

Moving the location of the hooks to VFE power domains has several
advantages.
1. Separation of concerns and functional decomposition.
vfe.c should be responsible for and know best how manage
power-domains for a VFE, excising from camss.c follows this
principle.
2. Embedding a pointer to genpd in struct camss_vfe{} meas that we can
dispense with a bunch of kmalloc array inside of camss.c.
3. Splitting up titan top gdsc from vfe/ife gdsc provides a base for

Right now we use the top-level camss structure to provide pointers via

In effect this hard-codes VFE indexes to power-domain indexes in the
dtsi and mandates a very particular ordering of power domains in the
dtsi, which bears no relationship to a real hardware dependency.
As a first step to rationalising the VFE power-domain code and breaking
the magic indexing in dtsi use per-VFE pointers to genpd linkages.
The top-level index in msm_vfe_subdev_init is still used to attain the

media: qcom: camss: Flag which VFEs require a power-domain
At the moment we have some complex code for determining if a VFE requires a
power-domain attachment. Particularly discordant in this scheme is the
subtle reliance on VFE and VFE Lite declaration ordering in our resources.
VFE id is used to determine if a VFE is lite or not and consequently if a
VFE requires power-domain attachment. VFE Lite though is not a correct
delineation between power-domain and non power-domain state since early
SoCs have neither VFE Lite nor power-domains attached to VFEs.
Introduce has_pd to the VFE resource structure to allow the CAMSS code to
understand if it needs to try to attach a power-domain for a given VFE.
As a side-effect from this we no longer need to care about VFE Lite or
non-Lite or the id number associated with either and which order the
VFE/VFE Lite was declared in.

Any V4L2 subdevice that implements controls and declares
V4L2_SUBDEV_FL_HAS_DEVNODE should also declare V4L2_SUBDEV_FL_HAS_EVENTS
and implement subscribe_event and unsubscribe_event hooks.
With that done, v4l2-compliance testing is now ok.
