version 6: - add platform_bus and platform_bus_type when register Ion devices to make them appear in /sys/devices/platform. - re-order include files in aphabetic order. version 5: - create a configuration flag to keep legacy Ion misc device version 4: - add a configuration flag to switch between legacy Ion misc device and one device per heap version. This change has been suggested after Laura talks at XDC 2017. version 3: - change ion_device_add_heap prototype to return a possible error. version 2: - simplify ioctl check like propose by Dan - make sure that we don't register more than ION_DEV_MAX heaps. Until now all ion heaps are addressing using the same device "/dev/ion". This way of working doesn't allow to give access rights (for example with SElinux rules) per heap. This series propose to have one device "/dev/ionX" per heap. Query heaps informations will be possible on each device node but allocation request will only be possible if heap_mask_id match with device minor number. Using legacy Ion misc device is still by setting ION_LEGACY_DEVICE_API configuration flag.
