Performance protocol fast channels 2. Reset Management Protocol among several other features. This series adds support for the above 2. The code is based on the cleanup[2] and Rx/async/delayed response series[3] and is available @[4] -- Regards, Sudeep v1[5]->v2: - Changed the macro SCMI_PERF_FC_RING_DB to use do {} while(0) - Renamed RESET_ARM_SCMI to RESET_SCMI and reworded Kconfig text - Dropped unused struct device pointer from scmi_reset_data - Added to_scmi_handle which helped to remove some repetitive code - Fixed some doxygen comments - Initialised rcdev.nr_resets - Fixed MODULE_DESCRIPTION [1] http://infocenter.arm.com/help/topic/com.arm.doc.den0056b/DEN0056B_System_Control_and_Management_Interface_v2_0.pdf [2] https://lore.kernel.org/lkml/20190726134531.8928-1-sudeep.holla@arm.com [3] https://lore.kernel.org/lkml/20190726135138.9858-1-sudeep.holla@arm.com/ [4] git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux.git scmi_updates [5] https://lore.kernel.org/lkml/20190726135954.11078-1-sudeep.holla@arm.com/ Sudeep Holla (5): firmware: arm_scmi: Add discovery of SCMI v2.0 performance fastchannels firmware: arm_scmi: Make use SCMI v2.0 fastchannel for performance protocol dt-bindings: arm: Extend SCMI to support new reset protocol firmware: arm_scmi: Add RESET protocol in SCMI v2.0 reset: Add support for resets provided by SCMI .../devicetree/bindings/arm/arm,scmi.txt | 17 ++ MAINTAINERS | 1 + drivers/firmware/arm_scmi/Makefile | 2 +- drivers/firmware/arm_scmi/perf.c | 257 +++++++++++++++++- drivers/firmware/arm_scmi/reset.c | 231 ++++++++++++++++ drivers/reset/Kconfig | 11 + drivers/reset/Makefile | 1 + drivers/reset/reset-scmi.c | 126 +++++++++ include/linux/scmi_protocol.h | 26 ++ 9 files changed, 663 insertions(+), 9 deletions(-) create mode 100644 drivers/firmware/arm_scmi/reset.c create mode 100644 drivers/reset/reset-scmi.c -- 2.17.1
