Subject: [PATCH v2 0/6] mailbox: arm_mhu: add support for doorbell mode


Hi,

This series adds doorbell support to ARM MHU mailbox controller driver.
Since we need to callback the different client based on the doorbel bits
triggered from the remote, we can manage with single channel for the set
of 32 doorbells.

Regards,
Sudeep

v1->v2:
	- Removed the notion od subchannels
	- Treat each bit in the MHU register as a doorbell and hence
	  different channel with respect to mailbox framework

v1: https://www.spinics.net/lists/kernel/msg2500461.html
