From 7002ca237b216d651d032439c45dc664f1f955bb Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Thu, 8 Oct 2020 20:14:52 +0100 Subject: mailbox: arm_mhu: Add ARM MHU doorbell driver The MHU drives the signal using a 32-bit register, with all 32 bits logically ORed together. The MHU provides a set of registers to enable software to set, clear, and check the status of each of the bits of this register independently. The use of 32 bits for each interrupt line enables software to provide more information about the source of the interrupt. For example, each bit of the register can be associated with a type of event that can contribute to raising the interrupt. This patch adds a separate the MHU controller driver for doorbel mode of operation using the extended DT binding to add support the same.
