Merge tag 'omap-for-v3.10/fixes-for-merge-window-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren: Omap fixes for things that were discovered during the merge window: - Few GPMC fixes and binding doc updates noted after sending pull requests for the GPMC branch. - Board fixes for beagle usb host and rx51 spi probe order - SoC fixes dt earlyprintk, omap1 dma and omap2+ id.c error handling fixes Then few minor things that are not strictly fixes but are good to get out of the way: - Add missing legacy mux registers for am/dm73x gpio - Add detection for am33xx pg2.1 silicon - Enable twl4030 audio modules in defconfig * tag 'omap-for-v3.10/fixes-for-merge-window-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP2+: Remove bogus IS_ERR_OR_NULL checking from id.c ARM: OMAP4+: omap2plus_defconfig: Enable audio via TWL6040 as module ARM: OMAP2: AM33XX: id: Add support for new AM335x PG2.1 Si omap: mux: add AM/DM37x gpios ARM: OMAP1: DMA: fix error handling in omap1_system_dma_init() ARM: OMAP2+: omap_device: use late_initcall_sync ARM: OMAP: RX-51: change probe order of touchscreen and panel SPI devices ARM: OMAP3: Beagle: Fix USB Host on beagle xM Ax/Bx ARM: OMAP2+: only WARN if a GPMC child probe function fail ARM: OMAP2+: only search for GPMC DT child nodes on probe Documentation: dt: update properties in TI GPMC NAND example Documentation: dt: update TI GPMC ethernet binding properties Signed-off-by: Olof Johansson <olof@lixom.net>
