This is the core dependency for achieving suspend/resume and cpuidle on AM335x and AM437x SoCs. I am hoping to have this series make 4.2. regards Suman > > .../bindings/remoteproc/wkup_m3_rproc.txt | 52 +++++ > Documentation/remoteproc.txt | 6 + > drivers/remoteproc/Kconfig | 13 ++ > drivers/remoteproc/Makefile | 1 + > drivers/remoteproc/remoteproc_core.c | 114 +++++++++- > drivers/remoteproc/wkup_m3_rproc.c | 249 +++++++++++++++++++++ > include/linux/platform_data/wkup_m3.h | 30 +++ > include/linux/remoteproc.h | 4 + > 8 files changed, 463 insertions(+), 6 deletions(-) > create mode 100644 Documentation/devicetree/bindings/remoteproc/wkup_m3_rproc.txt > create mode 100644 drivers/remoteproc/wkup_m3_rproc.c > create mode 100644 include/linux/platform_data/wkup_m3.h > -- 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
