media: mediatek: vcodec: Only apply 4K frame sizes on decoder formats

2023-05-26T09:47:47+00:00

When VCODEC_CAPABILITY_4K_DISABLED is not set in dec_capability, skip
formats that are not MTK_FMT_DEC so only decoder formats is updated in
mtk_init_vdec_params.

media: camss: camss-video: Don't zero subdev format again after initialization

2023-05-26T09:47:30+00:00

In an earlier commit, setting the which field of the subdev format struct
in video_get_subdev_format was moved to a designated initializer that also
zeroes all other fields. However, the memset call that was zeroing the
fields earlier was left in place, causing the which field to be cleared
after being set in the initializer.

Remove the memset call from video_get_subdev_format to avoid clearing the
initialized which field.

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]

      |                                    ^~~~

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:

  328 | static int mxc_isi_pm_resume(struct device *dev)

  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.

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.
