These updates are all for board specific code, including * defconfig updates for shmobile, davinci, bcm2835, imx, omap and tegra * SD/MMC and I2C support on bcm2835 (Raspberry PI) * minor updates for PXA * shmobile updates to GPIO usage in board files * More things in OMAP board files are moved over to device tree probing * Better support for audio devices on some OMAP platforms Conflicts include the omap board-apollon.c file that is removed without a replacement, and conflicting context in the 4430sdp board file. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUSUyPmCrR//JCVInAQKc4xAAm3UXWLjjIecgdcWperYzUn8wVGg2sRvT eFFtGvj3iC+HttPw01O2uVn2O/ixW6SJIgls1O3VTt6IKXPQg3OCjeu1/1vvgq14 IWuOVS9TLUS4IWkbIvQSdWrDTHocon1Umx+yIgyOpenHBn6kHMg1Tx6qQlUKKo8q ne8DKlAfSmao2oHg08Biuzc+cjUOCj7Dq57P1Y5gRhtmdXiFfvdd6GytyFAGUl/m 60c7BECUs9ileeAUTgehsUk84uV9w/FHeWhccxKspd8GjuHg31t5lB/PEEud34FK CTBWoPRn/xG6qjmp34kjP2zIFVfiYYscJpSzXw+cOmPx2gNcs9mGUflAmG9I2t/C TPuRCgmhqjZkfHjoNPUaGSvLa4m3279lrqxVqU6BWs8NlqzXSma1rqUKCxikV4lR OlPasykwIGdHoJWyrm517RRkLq9Jn2XxtZmequp8TAsUBzW1Su3ZNArSQ6VqGTgs W8T20UGVj4bDaAUG4VICeRZGIJx5wknEr11NrRL1a0/EFhFUxNFZf5JAs1YHw/Yi rJP8oTppbo6eAaTThc6/a1/rklu8TUcRvmeS+iIH4IFxbroqc/ntAYd16+cKhPbO EJtvUv2B3WQZesV7zmDG4TzleYjgYeFxPzTeYHHOYRIgDA3al2eSlp6EIZULSmul gqxlMv/YHF8= =/qBE -----END PGP SIGNATURE----- Merge tag 'boards' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC board specific changes from Arnd Bergmann: "These updates are all for board specific code, including - defconfig updates for shmobile, davinci, bcm2835, imx, omap and tegra - SD/MMC and I2C support on bcm2835 (Raspberry PI) - minor updates for PXA - shmobile updates to GPIO usage in board files - More things in OMAP board files are moved over to device tree probing - Better support for audio devices on some OMAP platforms" * tag 'boards' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (55 commits) ARM: imx_v4_v5_defconfig: Add VPU support ARM: imx: configs: enable netfilter support ARM: OMAP2+: Fix twl section warnings related to omap_twl4030_audio_init ARM: OMAP2+: omap2plus_defconfig: enable omap1 rtc RX-51: Register twl4030-madc device RX-51: Add leds lp5523 names from Maemo 5 2.6.28 kernel ARM: OMAP2+: AM33XX: omap2plus_defconfig: Add support for few drivers ARM: OMAP1: nokia770: enable CBUS/Retu ARM: OMAP2+: omap2plus_defconfig: enable CMA allocator ARM: OMAP2+: omap2plus_defconfig: enable TFP410 chip support ARM: OMAP3: igep0020: simplify GPIO LEDs dependencies ARM: OMAP2+: craneboard: support the TPS65910 PMU ARM: OMAP2+: craneboard: support NAND device ARM: OMAP3: cm-t3517: add MMC support ARM: OMAP2+: Remove apollon board support ARM: shmobile: armadillo800eva: set clock rates before timer init ARM: tegra: defconfig updates ARM: shmobile: mackerel: Use gpio_request_one() ARM: shmobile: kzm9g: Use gpio_request_one() ARM: shmobile: bonito: Use gpio_request_one() ...
