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 will only add support for Amlogic GXBB SoC.
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 last patch depends on the "Platform MHU" dtsi patch.
Changes since v1 at : http://lkml.kernel.org/r/1471515066-3626-1-git-send-email-narmstrong@baylibre.com - Dropped vendor_send_message and rockchip vendor mechanism patches - Merged alternate functions into main functions using is_legacy boolean - Added DT match table to set is_legacy to true - Kept alternate scpi_ops structure for legacy
Neil Armstrong (7): scpi: Add alternative legacy structures, functions and macros scpi: Use legacy variants command index calling scpi_send_message scpi: Add support for Legacy match table for Amlogic GXBB SoC 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
