This version addresses some\ncomments from Russell King and Johan Hovold in v3 found here [1].\n\nThe main change in this version is dropping the additions to the\narch/arm/kernel/asm-offsets.c file and instead generating our own local\n\"emif-asm-offsets.h\" using the same strategy in the drivers/memory Makefile.\nThis keeps our driver changes out of the arch or platform code and is a\ncleaner implementation. Otherwise some small fixups based on comments from\nJohan in v3 were done.\n\nThis code is required for low-power modes to work on AM335x and AM437x and a\nforthcoming PM series for those platforms will depend on this series. After\nboth this and the PM series are reviewed I will send the necessary device tree\nchanges for both, but in the meantime all remaining patches for am335x and\nam437x PM can be found here [2].\n\nRegards,\nDave\n\n[1] https://www.spinics.net/lists/linux-omap/msg138314.html\n[2] https://github.com/dgerlach/linux-pm/tree/upstream/v4.14/amx3-suspend-v4\n\nDave Gerlach (2):\n Documentation: dt: Update ti,emif bindings\n memory: ti-emif-sram: introduce relocatable suspend/resume handlers\n\n .../bindings/memory-controllers/ti/emif.txt | 18 +-\n drivers/memory/.gitignore | 1 +\n drivers/memory/Kconfig | 10 +\n drivers/memory/Makefile | 20 ++\n drivers/memory/emif-asm-offsets.c | 22 ++\n drivers/memory/emif.h | 17 ++\n drivers/memory/ti-emif-pm.c | 339 +++++++++++++++++++++\n drivers/memory/ti-emif-sram-pm.S | 334 ++++++++++++++++++++\n include/linux/ti-emif-sram.h | 148 +++++++++\n 9 files changed, 908 insertions(+), 1 deletion(-)\n create mode 100644 drivers/memory/.gitignore\n create mode 100644 drivers/memory/emif-asm-offsets.c\n create mode 100644 drivers/memory/ti-emif-pm.c\n create mode 100644 drivers/memory/ti-emif-sram-pm.S\n create mode 100644 include/linux/ti-emif-sram.h" }
