Simon, All, This patch series is my attempt to learn device tree with a driver I'm familiar with. Also, to create a real, working example for fdt in U-boot.
To make this work, I applied v2 of Simon Glass' patch series (what this email is in reply to) against v2011.09-rc1. I then cherry picked my dreamplug board support patch. Last, I applied the following series. It works, although with CONFIG_OF_EMBED. I haven't tried _SEPARATE yet. Some thoughts: 1.) 'kirkwood-dreamplug.dts' can be renamed 'dreamplug.dts'. Due to machine_is_XXX 'dreamplug' will be unique, concise, and descriptive. This requires changes to Simon Glass' patchset. 2.) The fdt files should be moved up one directory level, in the end, it should look like: board/Marvell/armada100-dt.c board/Marvell/armada100-dt.h board/Marvell/armada100.dtsi board/Marvell/dreamplug.dts board/Marvell/gplugd.dts # this includes armada100.dtsi board/Marvell/guruplug.dts board/Marvell/kirkwood.dtsi board/Marvell/kirkwood-dt.c board/Marvell/kirkwood-dt.h board/Marvell/openrd.dts board/Marvell/sheevaplug.dts ... board/Marvell/<other boards>.dts This also requires changes to Simon's patchset. 3.) Since mach names (dreamplug) and SoC names (kirkwood) are unique, should we put all .dts and .dtsi files in one dir? eg /dts ? This would facilitate migration to Grant Likely's device-tree.git whereever and whenever it lands. This is also similar to how Linux currently does it (arch/arm/boot/dts/) Jason Cooper (4): fdt: remove i2c example code. fdt_decode: make more available. mvrtc: add fdt support. dreamplug: enable fdt board/Marvell/dreamplug/kirkwood-dreamplug.dts | 12 +++++ board/Marvell/dreamplug/kirkwood.dtsi | 25 ++++++++++ common/fdt_decode.c | 26 ++-------- drivers/rtc/mvrtc.c | 62 ++++++++++++++++++++++- drivers/rtc/mvrtc.h | 7 +++ include/configs/dreamplug.h | 5 ++ include/fdt_decode.h | 46 +++++------------ 7 files changed, 128 insertions(+), 55 deletions(-) create mode 100644 board/Marvell/dreamplug/kirkwood-dreamplug.dts create mode 100644 board/Marvell/dreamplug/kirkwood.dtsi _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
