0d23b548d7 media: mt9m114: Fix deadlock in get_frame_interval/set_frame_interval
commit 298d1471cf upstream.

Getting / Setting the frame interval using the V4L2 subdev pad ops
get_frame_interval/set_frame_interval causes a deadlock, as the
subdev state is locked in the [1] but also in the driver itself.

In [2] it's described that the caller is responsible to acquire and
release the lock in this case. Therefore, acquiring the lock in the
driver is wrong.

Remove the lock acquisitions/releases from mt9m114_ifp_get_frame_interval()
and mt9m114_ifp_set_frame_interval().

commit 76142b137b upstream.

ov2659_probe() doesn't properly free control handler resources in failure
paths, causing memory leaks. Add v4l2_ctrl_handler_free() to prevent these

5c54ef825c media: hi556: correct the test pattern configuration
commit 020f602b06 upstream.

Hynix hi556 support 8 test pattern modes:
hi556_test_pattern_menu[] = {
{
	"Disabled",
	"Solid Colour",
	"100% Colour Bars",
	"Fade To Grey Colour Bars",
	"PN9",
	"Gradient Horizontal",
	"Gradient Vertical",
	"Check Board",
	"Slant Pattern",
}

The test pattern is set by a 8-bit register according to the
specification.
+--------+-------------------------------+
| BIT[0] |  Solid color                  |
+--------+-------------------------------+
| BIT[1] |  Color bar                    |
+--------+-------------------------------+
| BIT[2] |  Fade to grey color bar       |
+--------+-------------------------------+
| BIT[3] |  PN9                          |
+--------+-------------------------------+
| BIT[4] |  Gradient horizontal          |
+--------+-------------------------------+
| BIT[5] |  Gradient vertical            |
+--------+-------------------------------+
| BIT[6] |  Check board                  |
+--------+-------------------------------+
| BIT[7] |  Slant pattern                |
+--------+-------------------------------+
Based on function above, current test pattern programming is wrong.
This patch fixes it by 'BIT(pattern - 1)'. If pattern is 0, driver
will disable the test pattern generation and set the pattern to 0.

f25d566c56 media: tc358743: Increase FIFO trigger level to 374
[ Upstream commit 86addd2531 ]

The existing fixed value of 16 worked for UYVY 720P60 over
2 lanes at 594MHz, or UYVY 1080P60 over 4 lanes. (RGB888
1080P60 needs 6 lanes at 594MHz).
It doesn't allow for lower resolutions to work as the FIFO
underflows.

374 is required for 1080P24 or 1080P30 UYVY over 2 lanes @
972Mbit/s, but >374 means that the FIFO underflows on 1080P50
UYVY over 2 lanes @ 972Mbit/s.

Whilst it would be nice to compute it, the required information
isn't published by Toshiba.

b42b107293 media: tc358743: Return an appropriate colorspace from tc358743_set_fmt
[ Upstream commit 377cc006a3 ]

When calling tc358743_set_fmt, the code was calling tc358743_get_fmt
to choose a valid format. However that sets the colorspace
based on information read back from the chip, not the colour
format requested.

The result was that if you called try or set format for UYVY
when the current format was RGB3 then you would get told SRGB,
and try RGB3 when current was UYVY and you would get told
SMPTE170M.

The value programmed in the VI_REP register for the colorspace
is always set by this driver, therefore there is no need to read
back the value, and never set to REC709.
Return the colorspace based on the format set/tried instead.

3e03ee3b65 media: tc358743: Check I2C succeeded during probe
[ Upstream commit 303d81635e ]

The probe for the TC358743 reads the CHIPID register from
the device and compares it to the expected value of 0.
If the I2C request fails then that also returns 0, so
the driver loads thinking that the device is there.

Generally I2C communications are reliable so there is
limited need to check the return value on every transfer,
therefore only amend the one read during probe to check
for I2C errors.

d41111bb46 media: hi556: Fix reset GPIO timings
[ Upstream commit 99f2211a9d ]

probe() requests the reset GPIO to be set to high when getting it.
Immeditately after this hi556_resume() is called and sets the GPIO low.

If the GPIO was low before requesting it this will result in the GPIO
only very briefly spiking high and the sensor not being properly reset.
The same problem also happens on back to back runtime suspend + resume.

Fix this by adding a sleep of 2 ms in hi556_resume() before setting
the GPIO low (if there is a reset GPIO).

The final sleep is kept unconditional, because if there is e.g. no reset
GPIO but a controllable clock then the sensor also needs some time after
enabling the clock.

1f78790d98 media: i2c: imx335: Fix frame size enumeration
commit b240df2913 upstream.

In commit cfa49ff055 ("media: i2c: imx335: Support 2592x1940 10-bit
mode") the IMX335 driver was extended to support multiple output
bitdepth modes.

This incorrectly extended the frame size enumeration to check against
the supported mbus_codes array instead of the supported mode/frame
array. This has the unwanted side effect of reporting the currently
supported frame size 2592x1944 three times.

Fix the check accordingly to report a frame size for each supported
size, which is presently only a single entry.

c2aa6567a6 media: tc358746: improve calculation of the D-PHY timing registers
[ Upstream commit 78d7265e2e ]

When calculating D-PHY registers, using data rates that are not multiples
of 16 can lead to precision loss in division operations. This can result in
register values that produce timing violations against the MIPI standard.

An example:
cfg->hs_clk_rate = 294MHz
hf_clk = 18

If the desired value in cfg->init is 100us, which is the minimum allowed
value, then the LINEINITCNT register is calculated as 1799. But since the
actual clock is 18.375MHz instead of 18MHz, this setting results in a time
that is shorter than 100us and thus violates the standard. The correct
value for LINEINITCNT would be 1837.

Improve the precision of calculations by using Hz instead of MHz as unit.

fc96a720d8 media: i2c: imx214: Fix link frequency validation
[ Upstream commit acc294519f ]

The driver defines IMX214_DEFAULT_LINK_FREQ 480000000, and then
IMX214_DEFAULT_PIXEL_RATE ((IMX214_DEFAULT_LINK_FREQ * 8LL) / 10),
which works out as 384MPix/s. (The 8 is 4 lanes and DDR.)

Parsing the PLL registers with the defined 24MHz input. We're in single
PLL mode, so MIPI frequency is directly linked to pixel rate.  VTCK ends
up being 1200MHz, and VTPXCK and OPPXCK both are 120MHz.  Section 5.3
"Frame rate calculation formula" says "Pixel rate
[pixels/s] = VTPXCK [MHz] * 4", so 120 * 4 = 480MPix/s, which basically
agrees with my number above.

3.1.4. MIPI global timing setting says "Output bitrate = OPPXCK * reg
0x113[7:0]", so 120MHz * 10, or 1200Mbit/s. That would be a link
frequency of 600MHz due to DDR.
That also matches to 480MPix/s * 10bpp / 4 lanes / 2 for DDR.

Keep the previous link frequency for backward compatibility.

6f77a6d2ea media: i2c: imx214: Rectify probe error handling related to runtime PM
commit ccc888d169 upstream.

There were multiple issues in the driver's probe function related to
error handling:

- Device's PM runtime status wasn't reverted to suspended on some errors
  in probe.

- Runtime PM was left enabled for the device on some probe errors.

- Device was left powered on if a probe failure happened or when it
  was removed when it was powered on.

- An extra pm_runtime_set_suspended() was issued in driver's remove
  function when the device was suspended.

Fix these bugs.

b933486f6b media: imx219: Adjust PLL settings based on the number of MIPI lanes
commit 591a07588c upstream.

Commit ceddfd4493 ("media: i2c: imx219: Support four-lane operation")
added support for device tree to allow configuration of the sensor to
use 4 lanes with a link frequency of 363MHz, and amended the advertised
pixel rate to 280.8MPix/s.

However it didn't change any of the PLL settings, so actually it would
have been running overclocked in the MIPI block, and with the frame
rate and exposure calculations being wrong as the pixel rate was
unchanged.

The pixel rate and link frequency advertised were taken from the "Clock
Setting Example" section of the datasheet. However those are based on an
external clock of 12MHz, and are unachievable with a clock of 24MHz - it
seems PREPLLCLK_VT_DIV and PREPLLCK_OP_DIV can ONLY be set via the
automatic configuration documented in "9-1-2 EXCK_FREQ setting depend on
INCK frequency", not by writing the registers.
The closest we can get with a 24MHz clock is 281.6MPix/s and 364MHz.

Dropping all support for the 363MHz link frequency would cause problems
for existing users, so allow it, but log a warning that the requested
value is being changed to the supported one.

6de9786c61 media: i2c: ds90ub960: Fix UB9702 VC map
commit 5dbbd0609b upstream.

The driver uses a static CSI-2 virtual channel mapping where all virtual
channels from an RX port are mapped to a virtual channel number matching
the RX port number.

The UB960 and UB9702 have different registers for the purpose, and the
UB9702 version is not correct. Each of the VC_ID_MAP registers do not
contain a single mapping, as the driver currently thinks, but two.

This can cause received VCs other than 0 to be mapped in a wrong way.

Fix this by writing both mappings to each register.
