This patchset aims to support the legacy SCPI firmware implementation that was delivered as early technology preview for the JUNO platform.
Finally a stable, maintained and public implementation for the SCPI protocol has been upstreamed part of the JUNO support and it is the recommended way of implementing SCP communication on ARMv8 platforms.
The Amlogic GXBB platform is using this legacy protocol, as the RK3368 & RK3399 platforms.
This patchset add support for the legacy protocol in the arm_scpi.c file, avoiding code duplication.
Last RFC discution tread can be found at : https://lkml.org/lkml/2016/8/9/210
The first patch is here to provide vendor commands on the official SCPI protocol, it can be delayed to another patchset.
Patches 8 & 9 are only here to demo how Rockchip support could be implemented, these patches should be delayed to a rockchip specific patchset.
The last patch depends on the "Platform MHU" dtsi patch.
Neil Armstrong (13): scpi: Add vendor_send_message to enable access to vendor commands scpi: Add alternative legacy structures and macros scpi: Add legacy send, prepare and handle remote functions scpi: Add legacy SCP functions calling legacy_scpi_send_message scpi: move of_match table before probe functions scpi: add priv_scpi_ops and fill legacy structure scpi: ignore init_versions failure if reported not supported scpi: add a vendor_msg mechanism in case the mailbox message differs scpi: implement rockchip support via the vendor_msg mechanism scpi: grow MAX_DVFS_OPPS to 16 entries dt-bindings: Add support for Amlogic GXBB SCPI Interface ARM64: dts: meson-gxbb: Add SRAM node ARM64: dts: meson-gxbb: Add SCPI with cpufreq & sensors Nodes
