Hi

These are targeted for the v6.13 cycle, i.e for the i3c/next branch
after v6.12-rc1 is tagged.

Patch 1/2 is stable looking material but I think it gets visible only
after patch 2/2 on a MIPI I3C HCI v1.0+ compatible HW so in my opinnion
should go through normal development cycle.

AMD folks: You said you have non-functional DMA mode on your HW. Can the
patch 2/2 make it functional or are there some other than interrupt
issues?

  i3c: mipi-i3c-hci: Mask ring interrupts before ring stop request
  i3c: mipi-i3c-hci: Handle interrupts according to current
    specifications
