[PATCH 0/3] mailbox: Allow direct registration to a channel

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Two mailbox controllers have channel/client binding mechanisms that are
controller-specific and not using the devicetree binding mechanisms. Mailbox
channel/client is conceptually done in two steps: selecting the channel
and binding the selected to channel to a client. Channel selection is sometimes
controller specific (pcc and omap are examples). The channel/client binding
code is all the same.

This small series de-duplicates and refactors the channel/client binding
into a common framework function: "mbox_bind_client" which all of the
channel selection mechanisms can use.

I found this duplicate code while working on the support for Gunyah hypervisor
message queues [1]. I've only been able to compile-test omap-maiblox and pcc,
however it is a straightforward conversion here.
