media: platform: mtk-mdp3: work around unused-variable warning

2023-05-08T11:11:25+00:00

When CONFIG_OF is disabled, the 'data' variable is not used at all
because of_match_node() turns into a dummy macro:

drivers/media/platform/mediatek/mdp3/mtk-mdp3-comp.c: In function 'mdp_comp_sub_create':
drivers/media/platform/mediatek/mdp3/mtk-mdp3-comp.c:1038:36: error: unused variable 'data' [-Werror=unused-variable]
 1038 |  const struct mtk_mdp_driver_data *data = mdp->mdp_data;
      |                                    ^~~~

Remove the variable again by moving the pointer dereference into the
of_match_node call.

media: nxp: ignore unused suspend operations

2023-05-08T11:11:25+00:00

gcc warns about some functions being unused when CONFIG_PM_SLEEP
is disabled:

drivers/media/platform/nxp/imx8-isi/imx8-isi-core.c:328:12: error: 'mxc_isi_pm_resume' defined but not used [-Werror=unused-function]
  328 | static int mxc_isi_pm_resume(struct device *dev)
      |            ^~~~~~~~~~~~~~~~~
drivers/media/platform/nxp/imx8-isi/imx8-isi-core.c:314:12: error: 'mxc_isi_pm_suspend' defined but not used [-Werror=unused-function]
  314 | static int mxc_isi_pm_suspend(struct device *dev)
      |            ^~~~~~~~~~~~~~~~~~

Use the modern SYSTEM_SLEEP_PM_OPS()/RUNTIME_PM_OPS() helpers in place
of the old SET_SYSTEM_SLEEP_PM_OPS()/SET_RUNTIME_PM_OPS() ones.

By convention, use pm_ptr() to guard the reference to the operations.
This makes no difference as long as the driver requires CONFIG_PM,
but is what users of SET_RUNTIME_PM_OPS() are supposed to do.

media: rcar-vin: Select correct interrupt mode for V4L2_FIELD_ALTERNATE

2023-05-08T11:11:25+00:00

When adding proper support for V4L2_FIELD_ALTERNATE it was missed that
this field format should trigger an interrupt for each field, not just
for the whole frame. Fix this by marking it as progressive in the
capture setup, which will then select the correct interrupt mode.

Tested on both Gen2 and Gen3 with the result of a doubling of the frame
rate for V4L2_FIELD_ALTERNATE. From a PAL video source the frame rate is
now 50, which is expected for alternate field capture.

The VIN modules on Gen3 can not scale NV12, fail format validation if
the user tries. Currently no frames are produced if this is attempted.

media: nxp: imx8-isi: fix buiding on 32-bit

2023-05-08T16:10:07+00:00

The #if check is wrong, leading to a build failure:

  drivers/media/platform/nxp/imx8-isi/imx8-isi-hw.c: In function 'mxc_isi_channel_set_inbuf':
  drivers/media/platform/nxp/imx8-isi/imx8-isi-hw.c:33:5: error: "CONFIG_ARCH_DMA_ADDR_T_64BIT" is not defined, evaluates to 0 [-Werror=undef]
     33 | #if CONFIG_ARCH_DMA_ADDR_T_64BIT
        |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

This could just be an #ifdef, but it seems nicer to just remove the
check entirely.  Apparently the only reason for the #ifdef is to avoid
another warning:

  drivers/media/platform/nxp/imx8-isi/imx8-isi-hw.c:55:24: error: right shift count >= width of type [-Werror=shift-count-overflow]

But this is best avoided by using the lower_32_bits()/upper_32_bits()
helpers.

media: nxp: imx8-isi: Remove 300ms sleep after enabling channel

2023-04-16T06:38:01+00:00

The current implementation of the mxc_isi_channel_enable() function has
a hard 300ms sleep. This was copied from the NXP BSP, which has since
dropped the sleep in a commit that implied the delay was meant to wait
for the sensor to be "stable". As the sensor is started after the ISI,
the delay won't affect sensor operation. Drop it.
