Those patch series make cameras on Nokia N900 partially working. Some more patches are needed, but I've already sent them for upstreaming so they are not part of the series:
https://lkml.org/lkml/2016/4/16/14 https://lkml.org/lkml/2016/4/16/33 As omap3isp driver supports only one endpoint on ccp2 interface, but cameras on N900 require different strobe settings, so far it is not possible to have both cameras correctly working with the same board DTS. DTS patch in the series has the correct settings for the front camera. This is a problem still to be solved. The needed pipeline could be made with: media-ctl -r media-ctl -l '"vs6555 binner 2-0010":1 -> "video-bus-switch":2 [1]' media-ctl -l '"video-bus-switch":0 -> "OMAP3 ISP CCP2":0 [1]' media-ctl -l '"OMAP3 ISP CCP2":1 -> "OMAP3 ISP CCDC":0 [1]' media-ctl -l '"OMAP3 ISP CCDC":2 -> "OMAP3 ISP preview":0 [1]' media-ctl -l '"OMAP3 ISP preview":1 -> "OMAP3 ISP resizer":0 [1]' media-ctl -l '"OMAP3 ISP resizer":1 -> "OMAP3 ISP resizer output":0 [1]' media-ctl -V '"vs6555 pixel array 2-0010":0 [SGRBG10/648x488 (0,0)/648x488 (0,0)/648x488]' media-ctl -V '"vs6555 binner 2-0010":1 [SGRBG10/648x488 (0,0)/648x488 (0,0)/648x488]' media-ctl -V '"OMAP3 ISP CCP2":0 [SGRBG10 648x488]' media-ctl -V '"OMAP3 ISP CCP2":1 [SGRBG10 648x488]' media-ctl -V '"OMAP3 ISP CCDC":2 [SGRBG10 648x488]' media-ctl -V '"OMAP3 ISP preview":1 [UYVY 648x488]' media-ctl -V '"OMAP3 ISP resizer":1 [UYVY 656x488]' and tested with: mplayer -tv driver=v4l2:width=656:height=488:outfmt=uyvy:device=/dev/video6 -vo xv -vf screenshot tv:// Ivaylo Dimitrov (8): smiaregs: Generic i2c register writing et8ek8: Toshiba 5MP sensor driver v4l: of: Support CSI-1 and CCP2 busses media: video-bus-switch: new driver ARM: dts: omap3-n900: enable cameras [media] omap3isp: Correctly set IO_OUT_SEL and VP_CLK_POL for CCP2 mode [media] omap3isp: Make sure CSI1 interface is enabled in CPP2 mode ARM: dts: omap3-n900: enable cameras - remove invalid entry Sakari Ailus (10): smiapp-pll: Take existing divisor into account in minimum divisor check smiapp: Add smiapp_has_quirk() to tell whether a quirk is implemented smiapp: Add quirk control support v4l: of: Call CSI2 bus csi2, not csi v4l: of: Obtain data bus type from bus-type property v4l: Add CSI1 and CCP2 bus type to enum v4l2_mbus_type v4l: of: Separate lane parsing from CSI-2 bus parameter parsing dt: bindings: v4l: Add bus-type video interface property dt: bindings: Add CSI1/CCP2 related properties to video-interfaces.txt omap3isp: dt: Add support for CSI1/CCP2 busses Sebastian Reichel (5): media: et8ek8: add device tree binding document media: add subdev type for bus switch smiapp: add CCP2 support v4l2-async: per notifier locking v4l2_device_register_subdev_nodes: allow calling multiple times Tuukka.O Toivonen (1): V4L fixes .../bindings/media/i2c/toshiba,et8ek8.txt | 56 + .../devicetree/bindings/media/video-interfaces.txt | 11 +- arch/arm/boot/dts/omap3-n900.dts | 139 ++ drivers/media/i2c/Kconfig | 1 + drivers/media/i2c/Makefile | 1 + drivers/media/i2c/smia/Kconfig | 17 + drivers/media/i2c/smia/Makefile | 2 + drivers/media/i2c/smia/et8ek8.c | 1788 ++++++++++++++++++++ drivers/media/i2c/smia/smiaregs.c | 724 ++++++++ drivers/media/i2c/smiapp-pll.c | 3 +- drivers/media/i2c/smiapp/smiapp-core.c | 18 +- drivers/media/i2c/smiapp/smiapp-quirk.h | 10 +- drivers/media/platform/Kconfig | 10 + drivers/media/platform/Makefile | 2 + drivers/media/platform/omap3isp/isp.c | 112 +- drivers/media/platform/omap3isp/ispccp2.c | 34 +- drivers/media/platform/omap3isp/ispreg.h | 4 + drivers/media/platform/omap3isp/omap3isp.h | 1 + drivers/media/platform/video-bus-switch.c | 366 ++++ drivers/media/v4l2-core/v4l2-async.c | 50 +- drivers/media/v4l2-core/v4l2-device.c | 3 + drivers/media/v4l2-core/v4l2-of.c | 137 +- include/media/smiaregs.h | 143 ++ include/media/v4l2-async.h | 2 + include/media/v4l2-mediabus.h | 4 + include/media/v4l2-of.h | 17 + include/uapi/linux/media.h | 1 + include/uapi/linux/v4l2-controls.h | 17 + 28 files changed, 3579 insertions(+), 94 deletions(-) create mode 100644 Documentation/devicetree/bindings/media/i2c/toshiba,et8ek8.txt create mode 100644 drivers/media/i2c/smia/Kconfig create mode 100644 drivers/media/i2c/smia/Makefile create mode 100644 drivers/media/i2c/smia/et8ek8.c create mode 100644 drivers/media/i2c/smia/smiaregs.c create mode 100644 drivers/media/platform/video-bus-switch.c create mode 100644 include/media/smiaregs.h -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
