Provide functions which get and set the 3A (Auto white balance/Auto
exposure/Auto
focus) parameters.
These are achieved by the ioctl request codes VIDIOC_G_EXT_CTRLS and
VIDIOC_S_EXT_CTRLS which have the following settings:
1. ctrl_class = V4L2_CTRL_CLASS_CAMERA
2. id = V4L2_CID_3A_PARAMETER
Also, provide function which get the 3A adjustment status.
This is achieved by the ioctl request codes VIDIOC_G_EXT_CTRLS which has the
following settings:
1. ctrl_class = V4L2_CTRL_CLASS_CAMERA
2. id = V4L2_CID_3A_STATUS
Fix the following three bugs about ON/OFF control of auto white balance and auto
exposure:
- The returned value of VIDIOC_G_CTRL with id = V4L2_CID_AUTO_WHITE_BALANCE is
different from V4L2 specification.
- Auto exposure is locked if auto white balance lock is requested.
- Auto exposure and auto white balance are locked if auto exposure lock is
requested.
This reverts commit b9ace36fcc.
This change was added by PR 625 but has a serious logic flaw. It removes all occurrences of INCDIROPT and replaces it with a definition in tools/Config.mk:
else ifeq ($(WINTOOL),y)
DEFINE = "$(TOPDIR)/tools/define.sh"
INCDIR = "$(TOPDIR)/tools/incdir.sh" -w
This logic flaw is the Config.mk is included in all Make.defs files BEFORE WINTOOL is defined. As a result, the definition is wrong in many places when building under Cygwin with a Windows native toolchain.
This sensor driver needs rework to match the needed layout for standar NuttX driver.
In the meantime it is moved to board specific sensors to fix the violation.
