[libcamera-devel] [PATCH v3 0/3] Add HeapAllocator

[Harvey Yang]

Hi all,

The series of patches added HeapAllocator, which uses DmaHeap (moved
from Raspberry Pi pipeline handler) and UdmaHeap to allocate heap
buffers.

Fixed the c'tor of DmaHeap, where I incorrectly mixed some udma heap
code.

I've only build-test it, and I'll need to test it on my virtual pipeline
handler patches, but please take a look and let me know if it makes
sense. Thanks!

BR,
Harvey
