X-Git-Url: http://git.dujemihanovic.xyz/img/static/gitweb.css?a=commitdiff_plain;h=c08decd29ec44b38262eaa93e0e66d3965d26232;p=u-boot.git

firmware: scmi: use multi channel in mailbox, optee and smccc agents

Updates .process_msg operators of the SCMI transport drivers that
supports multi-channel to use it now that drivers do provide
the reference through channel argument. These are the mailbox
agent, the optee agent and the smccc agent.
