[libcamera-devel] [PATCH v3 0/2] Replace Raspberry Pi VCSM CMA with DMA heaps

[Laurent Pinchart]

Hi Naush,

I'm posting a v3 of your patches as I've rebased them on top of the
IPAInterface::configure() series that was recently merged. This version
contains the few changes I mentioned in the review of v2. Would you be
able to give it a last round of review ?

Feel free to push the kernel changes whenever is convenient, and notify
me when it will be done. I'll push this series right after.

  libcamera: pipeline: ipa: raspberrypi: Use dma heap allocs for LS
    tables
