This series adds DTS for following Beaglebone capes: Memory Cape: http://beagleboardtoys.info/index.php?title=BeagleBone_Memory_Expansion NAND Cape: http://beagleboardtoys.info/index.php?title=BeagleBone_4Gb_16-Bit_NAND_Module NOR Cape: http://elinux.org/Beagleboardtoys:BeagleBone_128Mb_16-Bit_NOR_Module LCD4 Cape: http://elinux.org/CircuitCo:BeagleBone_LCD4 Based on Tree: git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap omap-for-v3.16/dt-v2 Acceptance of cape DTS in mainline is still under discussion [1], so multiple 'Tested-by' would be helpful. Note: In order to avoid conflicts with existing DTS, device nodes added in these patches have status="disabled", and need to be "enabled" via u-boot. DT nodes can be selectively enabled | disabled via u-boot [2] Example: Below sequence works for NAND cape patch. --------------- /* load DTB */ u-boot> tftp 0x81000000 am335x-boneblack.dtb u-boot> fdt addr 0x81000000 /* disable MMC2 node */ u-boot> fdt list /ocp/mmc@481d8000 u-boot> fdt set /ocp/mmc@481d8000 status \d\i\s\a\b\l\e\d u-boot> fdt list /ocp/mmc@481d8000 status /* enable GPMC node */ u-boot> fdt list /ocp/gpmc u-boot> fdt set /ocp/gpmc status \o\k\a\y u-boot> fdt list /ocp/gpmc status /* enable ELM node */ u-boot> fdt list /ocp/elm u-boot> fdt set /ocp/elm status \o\k\a\y u-boot> fdt list /ocp/elm status /* boot uImage */ tftp 0x82000000 uImage bootm 0x82000000 - 0x81000000 Note: "fdt set" command does not accept string literals as binding values, it internally converts them to string, so escape sequenced characters were used here.. "okay" == \o\k\a\y "disabled" == \d\i\s\a\b\l\e\d" --------------- [1] http://www.spinics.net/lists/linux-omap/msg108505.html [2] http://www.denx.de/wiki/view/DULG/UBootCmdFDT Pekon Gupta (3): ARM: dts: am335x-bone: add support for beaglebone NAND cape ARM: dts: am335x-bone: add support for beaglebone NOR cape ARM: dts: am335x-bone: add support for beaglebone LCD4 cape arch/arm/boot/dts/am335x-bone-display-cape.dts | 104 +++++++++++ arch/arm/boot/dts/am335x-bone-memory-cape.dts | 249 +++++++++++++++++++++++++ arch/arm/boot/dts/am335x-bone.dts | 2 + arch/arm/boot/dts/am335x-boneblack.dts | 2 + 4 files changed, 357 insertions(+) create mode 100644 arch/arm/boot/dts/am335x-bone-display-cape.dts create mode 100644 arch/arm/boot/dts/am335x-bone-memory-cape.dts -- 1.8.5.1.163.gd7aced9 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
