Hi, At the last Plumbers and Linaro Connect, there was some discussion related to Ion. One of the items that came up towards eventually getting Ion out of staging was some concept of stable devicetree bindings. This is a proof of concept for bindings. Most of this is based on previously submitted work (https://lkml.org/lkml/2015/6/30/425 thank you Andrew Andrianov for getting this started!) and also the out of tree qcom bindings (available somewhere on codeaurora.org). As the title indicates, this is an RFC and the purpose here is to get feedback on if these bindings would potentially work. If there are platforms out there that don't use devicetree, the bindings would hopefully also serve as a guide for how to setup the platform data for heaps like CMA. One of the big things this series improves on is giving a standard mechanism for defining and allocating memory for all heap types. DMA/CMA is handled as well as memory for carveout and chunk heaps. Further TODO: - Need to fixup include paths so heap types can be cleanly included in DTS files - Figure out callbacks or similar for support custom platform heaps Laura Abbott (2): WIP: Devicetree bindings for Ion staging: ion: Add files for parsing the devicetree (WIP) drivers/staging/android/ion/Kconfig | 10 ++ drivers/staging/android/ion/Makefile | 7 +- drivers/staging/android/ion/devicetree.txt | 53 +++++++++ drivers/staging/android/ion/ion_of.c | 185 +++++++++++++++++++++++++++++ drivers/staging/android/ion/ion_of.h | 3 + 5 files changed, 255 insertions(+), 3 deletions(-) create mode 100644 drivers/staging/android/ion/devicetree.txt create mode 100644 drivers/staging/android/ion/ion_of.c create mode 100644 drivers/staging/android/ion/ion_of.h -- 2.4.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
