Subject: [PATCH V5 0/2] firmware: arm_scmi: add smc/hvc transports support
Date: Sun,  8 Mar 2020 21:24:37 +0800	[thread overview]
Message-ID: <1583673879-20714-1-git-send-email-peng.fan@nxp.com> (raw)

From: Peng Fan <peng.fan@nxp.com>

V5:
 Add Rob's R-b tag for patch 1
 Add mutex for patch 2

V4:
 Drop prot_id in scmi_chan_info, since not used for now.

V3:
 Add back arm,scmi-smc compatible string
 Change smc-id to arm,smc-id
 Directly use arm_smccc_1_1_invoke
 Add prot_id in scmi_chan_info for per protocol shmem usage.

V2:
 patch 1/2: only add smc-id property
 patch 2/2: Parse smc/hvc from psci node
	    Use prot_id as 2nd arg when issue smc/hvc
	    Differentiate tranports using mboxes or smc-id property
https://lore.kernel.org/patchwork/cover/1193435/

This is to add smc/hvc transports support, based on Viresh's v6.
SCMI firmware could be implemented in EL3, S-EL1, NS-EL2 or other
A core exception level. Then smc/hvc could be used. And for vendor
specific firmware, a wrapper layer could added in EL3, S-EL1,
NS-EL2 and etc to translate SCMI calls to vendor specific firmware calls.

A new compatible string arm,scmi-smc is added. arm,scmi is still for
mailbox transports.

Per smc/hvc, only Tx supported.
