+TODO (general):
+==================================
+
+- User space interface refinement
+ - Controls should be used when possible rather than private ioctl
+ - No enums should be used
+ - Use of MC and V4L2 subdev APIs when applicable
+ - Single interface header might suffice
+ - Current interface forces to configure everything at once
+- Get rid of the dm365_ipipe_hw.[ch] layer
+- Active external sub-devices defined by link configuration; no strcmp
+ needed
+- More generic platform data (i2c adapters)
+- The driver should have no knowledge of possible external subdevs; see
+ struct vpfe_subdev_id
+- Some of the hardware control should be refactorede
+- Check proper serialisation (through mutexes and spinlocks)
+- Names that are visible in kernel global namespace should have a common
+ prefix (or a few)
+- While replacing the older driver in media folder, provide a compatibility
+ layer and compatibility tests that warrants (using the libv4l's LD_PRELOAD
+ approach) there is no regression for the users using the older driver.
+
+Building of uImage and Applications:
+==================================
+
+As of now since the interface will undergo few changes all the include
+files are present in staging itself, to build for dm365 follow below steps,
+
+- copy vpfe.h from drivers/staging/media/davinci_vpfe/ to
+ include/media/davinci/ folder for building the uImage.
+- copy davinci_vpfe_user.h from drivers/staging/media/davinci_vpfe/ to
+ include/uapi/linux/davinci_vpfe.h, and add a entry in Kbuild (required
+ for building application).
+- copy dm365_ipipeif_user.h from drivers/staging/media/davinci_vpfe/ to
+ include/uapi/linux/dm365_ipipeif.h and a entry in Kbuild (required
+ for building application).
