This patch adds support for APM X-Gene SoC Queue Manager/Traffic Manager. QMTM is required by APM X-Gene SoC Ethernet, PktDMA (XOR Engine) and Security Engine subsystems. All subsystems communicate with QMTM using messages which include information about the work to be performed and the location of associated data buffers. V3: * Switch to mailbox framework * Add support for little and big endian kernel * Change virt_to_phys function call to dma_zalloc_coherent V2: * Adding COMPILE_TEST dependency for QMTM in Kconfig * Updated license banner as per review comments * Fixed alignment for macros * Changed EXPORT_SYMBOL to EXPORT_SYMBOL_GPL V1: * inital version Signed-off-by: Ravi Patel <rapatel@xxxxxxx> Signed-off-by: Keyur Chudgar <kchudgar@xxxxxxx> --- Ravi Patel (4): Documentation: mailbox: APM X-Gene SoC QMTM Documentation: devicetree: bindings for APM X-Gene SoC QMTM mailbox: xgene: base driver for APM X-Gene SoC QMTM arm64: boot: dts: entries for APM X-Gene SoC QMTM .../devicetree/bindings/mailbox/apm-xgene-qmtm.txt | 53 ++ Documentation/mailbox/apm-xgene-qmtm.txt | 149 ++++++ MAINTAINERS | 9 + arch/arm64/boot/dts/apm-storm.dtsi | 18 +- drivers/mailbox/Kconfig | 2 + drivers/mailbox/Makefile | 1 + drivers/mailbox/xgene/Kconfig | 9 + drivers/mailbox/xgene/Makefile | 7 + drivers/mailbox/xgene/xgene_qmtm_main.c | 516 ++++++++++++++++++++ drivers/mailbox/xgene/xgene_qmtm_main.h | 112 +++++ drivers/mailbox/xgene/xgene_qmtm_storm.c | 358 ++++++++++++++ include/linux/platform_data/xgene_qmtm.h | 300 ++++++++++++ 12 files changed, 1533 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/mailbox/apm-xgene-qmtm.txt create mode 100644 Documentation/mailbox/apm-xgene-qmtm.txt create mode 100644 drivers/mailbox/xgene/Kconfig create mode 100644 drivers/mailbox/xgene/Makefile create mode 100644 drivers/mailbox/xgene/xgene_qmtm_main.c create mode 100644 drivers/mailbox/xgene/xgene_qmtm_main.h create mode 100644 drivers/mailbox/xgene/xgene_qmtm_storm.c create mode 100644 include/linux/platform_data/xgene_qmtm.h -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
