Some touch controllers send out touch data in a similar way to a greyscale frame grabber. Add new device type VFL_TYPE_TOUCH: - This uses a new device prefix v4l-touch for these devices, to stop generic capture software from treating them as webcams. Otherwise, touch is treated similarly to video capture. - Add V4L2_INPUT_TYPE_TOUCH - Add MEDIA_INTF_T_V4L_TOUCH - Add V4L2_CAP_TOUCH to indicate device is a touch device Add formats: - V4L2_TCH_FMT_DELTA_TD16 for signed 16-bit touch deltas - V4L2_TCH_FMT_DELTA_TD08 for signed 16-bit touch deltas - V4L2_TCH_FMT_TU16 for unsigned 16-bit touch data - V4L2_TCH_FMT_TU08 for unsigned 8-bit touch data This support will be used by: - Atmel maXTouch (atmel_mxt_ts) - Synaptics RMI4. - sur40 Signed-off-by: Nick Dyer <nick@shmanahar.org> Tested-by: Chris Healy <cphealy@gmail.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Acked-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> |
