| 2 | ================================== |
| 3 | |
| 4 | - User space interface refinement |
| 5 | - Controls should be used when possible rather than private ioctl |
| 6 | - No enums should be used |
| 7 | - Use of MC and V4L2 subdev APIs when applicable |
| 8 | - Single interface header might suffice |
| 9 | - Current interface forces to configure everything at once |
| 10 | - Get rid of the dm365_ipipe_hw.[ch] layer |
| 11 | - Active external sub-devices defined by link configuration; no strcmp |
| 12 | needed |
| 13 | - More generic platform data (i2c adapters) |
| 14 | - The driver should have no knowledge of possible external subdevs; see |
| 15 | struct vpfe_subdev_id |
| 16 | - Some of the hardware control should be refactorede |
| 17 | - Check proper serialisation (through mutexes and spinlocks) |
| 18 | - Names that are visible in kernel global namespace should have a common |
| 19 | prefix (or a few) |
| 20 | - While replacing the older driver in media folder, provide a compatibility |
| 21 | layer and compatibility tests that warrants (using the libv4l's LD_PRELOAD |
| 22 | approach) there is no regression for the users using the older driver. |
| 23 | |
| 24 | Building of uImage and Applications: |
| 25 | ================================== |
| 26 | |
| 27 | As of now since the interface will undergo few changes all the include |
| 28 | files are present in staging itself, to build for dm365 follow below steps, |
| 29 | |
| 30 | - copy vpfe.h from drivers/staging/media/davinci_vpfe/ to |
| 31 | include/media/davinci/ folder for building the uImage. |
| 32 | - copy davinci_vpfe_user.h from drivers/staging/media/davinci_vpfe/ to |
| 33 | include/uapi/linux/davinci_vpfe.h, and add a entry in Kbuild (required |
| 34 | for building application). |
| 35 | - copy dm365_ipipeif_user.h from drivers/staging/media/davinci_vpfe/ to |
| 36 | include/uapi/linux/dm365_ipipeif.h and a entry in Kbuild (required |
| 37 | for building application). |
