media: add imx355 camera sensor driver
Add a v4l2 sub-device driver for the Sony imx355 image sensor.
This is a camera sensor using the i2c bus for control and the
csi-2 bus for data.
This driver supports following features:
- manual exposure and analog/digital gain control support
- vblank/hblank control support
- 4 test patterns control support
- vflip/hflip control support (will impact the output bayer order)
- support following resolutions:
- 3268x2448, 3264x2448, 3280x2464 @ 30fps
- 1940x1096, 1936x1096, 1924x1080, 1920x1080 @ 60fps
- 1640x1232, 1640x922, 1300x736, 1296x736,
1284x720, 1280x720 820x616 @ 120fps
- support 4 bayer orders output (via change v/hflip)
- SRGGB10(default), SGRBG10, SGBRG10, SBGGR10

media: add imx355 camera sensor driver
Add a v4l2 sub-device driver for the Sony imx355 image sensor.
This is a camera sensor using the i2c bus for control and the
csi-2 bus for data.
This driver supports following features:
- manual exposure and analog/digital gain control support
- vblank/hblank control support
- 4 test patterns control support
- vflip/hflip control support (will impact the output bayer order)
- support following resolutions:
- 3268x2448, 3264x2448, 3280x2464 @ 30fps
- 1940x1096, 1936x1096, 1924x1080, 1920x1080 @ 60fps
- 1640x1232, 1640x922, 1300x736, 1296x736,
1284x720, 1280x720 820x616 @ 120fps
- support 4 bayer orders output (via change v/hflip)
- SRGGB10(default), SGRBG10, SGBRG10, SBGGR10

media: v4l2-subdev: add subdev-wide state struct
We have 'struct v4l2_subdev_pad_config' which contains configuration for
a single pad used for the TRY functionality, and an array of those
structs is passed to various v4l2_subdev_pad_ops.
I was working on subdev internal routing between pads, and realized that
there's no way to add TRY functionality for routes, which is not pad
specific configuration. Adding a separate struct for try-route config
wouldn't work either, as e.g. set-fmt needs to know the try-route
configuration to propagate the settings.
This patch adds a new struct, 'struct v4l2_subdev_state' (which at the
moment only contains the v4l2_subdev_pad_config array) and the new
struct is used in most of the places where v4l2_subdev_pad_config was
used. All v4l2_subdev_pad_ops functions taking v4l2_subdev_pad_config
are changed to instead take v4l2_subdev_state.
The changes to drivers/media/v4l2-core/v4l2-subdev.c and
include/media/v4l2-subdev.h were written by hand, and all the driver
changes were done with the semantic patch below. The spatch needs to be
applied to a select list of directories. I used the following shell
commands to apply the spatch:
dirs="drivers/media/i2c drivers/media/platform drivers/media/usb drivers/media/test-drivers/vimc drivers/media/pci drivers/staging/media"
for dir in $dirs; do spatch -j8 --dir --include-headers --no-show-diff --in-place --sp-file v4l2-subdev-state.cocci $dir; done
Note that Coccinelle chokes on a few drivers (gcc extensions?). With
minor changes we can make Coccinelle run fine, and these changes can be
reverted after spatch. The diff for these changes is:

media: v4l2-subdev: add subdev-wide state struct
We have 'struct v4l2_subdev_pad_config' which contains configuration for
a single pad used for the TRY functionality, and an array of those
structs is passed to various v4l2_subdev_pad_ops.
I was working on subdev internal routing between pads, and realized that
there's no way to add TRY functionality for routes, which is not pad
specific configuration. Adding a separate struct for try-route config
wouldn't work either, as e.g. set-fmt needs to know the try-route
configuration to propagate the settings.
This patch adds a new struct, 'struct v4l2_subdev_state' (which at the
moment only contains the v4l2_subdev_pad_config array) and the new
struct is used in most of the places where v4l2_subdev_pad_config was
used. All v4l2_subdev_pad_ops functions taking v4l2_subdev_pad_config
are changed to instead take v4l2_subdev_state.
The changes to drivers/media/v4l2-core/v4l2-subdev.c and
include/media/v4l2-subdev.h were written by hand, and all the driver
changes were done with the semantic patch below. The spatch needs to be
applied to a select list of directories. I used the following shell
commands to apply the spatch:
dirs="drivers/media/i2c drivers/media/platform drivers/media/usb drivers/media/test-drivers/vimc drivers/media/pci drivers/staging/media"
for dir in $dirs; do spatch -j8 --dir --include-headers --no-show-diff --in-place --sp-file v4l2-subdev-state.cocci $dir; done
Note that Coccinelle chokes on a few drivers (gcc extensions?). With
minor changes we can make Coccinelle run fine, and these changes can be
reverted after spatch. The diff for these changes is:

csi-2 bus for data.
This driver supports following features:
- manual exposure and analog/digital gain control support
- vblank/hblank control support
- 4 test patterns control support
- vflip/hflip control support (will impact the output bayer order)
- support following resolutions:
- 3268x2448, 3264x2448, 3280x2464 @ 30fps
- 1940x1096, 1936x1096, 1924x1080, 1920x1080 @ 60fps
- 1640x1232, 1640x922, 1300x736, 1296x736,
1284x720, 1280x720 820x616 @ 120fps
- support 4 bayer orders output (via change v/hflip)
- SRGGB10(default), SGRBG10, SGBRG10, SBGGR10

csi-2 bus for data.
This driver supports following features:
- manual exposure and analog/digital gain control support
- vblank/hblank control support
- 4 test patterns control support
- vflip/hflip control support (will impact the output bayer order)
- support following resolutions:
- 3268x2448, 3264x2448, 3280x2464 @ 30fps
- 1940x1096, 1936x1096, 1924x1080, 1920x1080 @ 60fps
- 1640x1232, 1640x922, 1300x736, 1296x736,
1284x720, 1280x720 820x616 @ 120fps
- support 4 bayer orders output (via change v/hflip)
- SRGGB10(default), SGRBG10, SGBRG10, SBGGR10

media: v4l2-subdev: add subdev-wide state struct
We have 'struct v4l2_subdev_pad_config' which contains configuration for
a single pad used for the TRY functionality, and an array of those
structs is passed to various v4l2_subdev_pad_ops.
I was working on subdev internal routing between pads, and realized that
there's no way to add TRY functionality for routes, which is not pad
specific configuration. Adding a separate struct for try-route config
wouldn't work either, as e.g. set-fmt needs to know the try-route
configuration to propagate the settings.
This patch adds a new struct, 'struct v4l2_subdev_state' (which at the
moment only contains the v4l2_subdev_pad_config array) and the new
struct is used in most of the places where v4l2_subdev_pad_config was
used. All v4l2_subdev_pad_ops functions taking v4l2_subdev_pad_config
are changed to instead take v4l2_subdev_state.
The changes to drivers/media/v4l2-core/v4l2-subdev.c and
include/media/v4l2-subdev.h were written by hand, and all the driver
changes were done with the semantic patch below. The spatch needs to be
applied to a select list of directories. I used the following shell
commands to apply the spatch:
dirs="drivers/media/i2c drivers/media/platform drivers/media/usb drivers/media/test-drivers/vimc drivers/media/pci drivers/staging/media"
for dir in $dirs; do spatch -j8 --dir --include-headers --no-show-diff --in-place --sp-file v4l2-subdev-state.cocci $dir; done
Note that Coccinelle chokes on a few drivers (gcc extensions?). With
minor changes we can make Coccinelle run fine, and these changes can be
reverted after spatch. The diff for these changes is:

media: add imx355 camera sensor driver
Add a v4l2 sub-device driver for the Sony imx355 image sensor.
This is a camera sensor using the i2c bus for control and the
csi-2 bus for data.
This driver supports following features:
- manual exposure and analog/digital gain control support
- vblank/hblank control support
- 4 test patterns control support
- vflip/hflip control support (will impact the output bayer order)
- support following resolutions:
- 3268x2448, 3264x2448, 3280x2464 @ 30fps
- 1940x1096, 1936x1096, 1924x1080, 1920x1080 @ 60fps
- 1640x1232, 1640x922, 1300x736, 1296x736,
1284x720, 1280x720 820x616 @ 120fps
- support 4 bayer orders output (via change v/hflip)
- SRGGB10(default), SGRBG10, SGBRG10, SBGGR10

media: v4l2-subdev: add subdev-wide state struct
We have 'struct v4l2_subdev_pad_config' which contains configuration for
a single pad used for the TRY functionality, and an array of those
structs is passed to various v4l2_subdev_pad_ops.
I was working on subdev internal routing between pads, and realized that
there's no way to add TRY functionality for routes, which is not pad
specific configuration. Adding a separate struct for try-route config
wouldn't work either, as e.g. set-fmt needs to know the try-route
configuration to propagate the settings.
This patch adds a new struct, 'struct v4l2_subdev_state' (which at the
moment only contains the v4l2_subdev_pad_config array) and the new
struct is used in most of the places where v4l2_subdev_pad_config was
used. All v4l2_subdev_pad_ops functions taking v4l2_subdev_pad_config
are changed to instead take v4l2_subdev_state.
The changes to drivers/media/v4l2-core/v4l2-subdev.c and
include/media/v4l2-subdev.h were written by hand, and all the driver
changes were done with the semantic patch below. The spatch needs to be
applied to a select list of directories. I used the following shell
commands to apply the spatch:
dirs="drivers/media/i2c drivers/media/platform drivers/media/usb drivers/media/test-drivers/vimc drivers/media/pci drivers/staging/media"
for dir in $dirs; do spatch -j8 --dir --include-headers --no-show-diff --in-place --sp-file v4l2-subdev-state.cocci $dir; done
Note that Coccinelle chokes on a few drivers (gcc extensions?). With
minor changes we can make Coccinelle run fine, and these changes can be
reverted after spatch. The diff for these changes is:

media: v4l2-subdev: add subdev-wide state struct
We have 'struct v4l2_subdev_pad_config' which contains configuration for
a single pad used for the TRY functionality, and an array of those
structs is passed to various v4l2_subdev_pad_ops.
I was working on subdev internal routing between pads, and realized that
there's no way to add TRY functionality for routes, which is not pad
specific configuration. Adding a separate struct for try-route config
wouldn't work either, as e.g. set-fmt needs to know the try-route
configuration to propagate the settings.
This patch adds a new struct, 'struct v4l2_subdev_state' (which at the
moment only contains the v4l2_subdev_pad_config array) and the new
struct is used in most of the places where v4l2_subdev_pad_config was
used. All v4l2_subdev_pad_ops functions taking v4l2_subdev_pad_config
are changed to instead take v4l2_subdev_state.
The changes to drivers/media/v4l2-core/v4l2-subdev.c and
include/media/v4l2-subdev.h were written by hand, and all the driver
changes were done with the semantic patch below. The spatch needs to be
applied to a select list of directories. I used the following shell
commands to apply the spatch:
dirs="drivers/media/i2c drivers/media/platform drivers/media/usb drivers/media/test-drivers/vimc drivers/media/pci drivers/staging/media"
for dir in $dirs; do spatch -j8 --dir --include-headers --no-show-diff --in-place --sp-file v4l2-subdev-state.cocci $dir; done
Note that Coccinelle chokes on a few drivers (gcc extensions?). With
minor changes we can make Coccinelle run fine, and these changes can be
reverted after spatch. The diff for these changes is:
