Merge tag 'omap-cleanup-devices-for-v3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup2
Changes to split plat-omap/devices.c into mach-omap1 and mach-omap2 except for the RNG driver that will be done later on. As this depends on omap-devel-hwmod-data-for-v3.5 and causes merge conflict with omap-fixes-non-critical-for-v3.5, this branch is based on merge of the two. By Tony Lindgren (7) and others via Tony Lindgren (4) and Paul Walmsley (1) * tag 'omap-cleanup-devices-for-v3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (27 commits) ARM: OMAP1: Pass dma request lines in platform data to MMC driver ARM: OMAP: Move omap_mmc_add() to mach-omap1 ARM: OMAP2: Use hwmod to initialize mmc for 2420 ARM: OMAP2+: Move omap_dsp_reserve_sdram_memblock() to mach-omap2 ARM: OMAP1: Move omap_init_uwire to mach-omap1 ARM: OMAP1: Move omap_init_audio() to keep the devices in alphabetical order ARM: OMAP2+: WDTIMER integration: fix !PM boot crash, disarm timer after hwmod reset ARM: OMAP2/3: hwmod data: Add 32k-sync timer data to hwmod database ARM: OMAP4: hwmod_data: Name the common irq for McBSP ports ARM: OMAP4: hwmod data: I2C: add flag for context restore ARM: OMAP3: hwmod_data: Rename the common irq for McBSP ports ARM: OMAP2xxx: hwmod data: add HDQ/1-wire hwmod ARM: OMAP3: hwmod data: add HDQ/1-wire hwmod ARM: OMAP2+: hwmod data: add HDQ/1-wire hwmod shared data ARM: OMAP2+: HDQ1W: add custom reset function ARM: OMAP2420: hwmod data: Add MMC hwmod data for 2420 arm: omap3: clockdomain data: Remove superfluous commas from gfx_sgx_3xxx_wkdeps[] ARM: OMAP2+: powerdomain: Get rid off duplicate pwrdm_clkdm_state_switch() API ARM: OMAP3: clock data: add clockdomain for HDQ functional clock ARM: OMAP3+: dpll: Configure autoidle mode only if it's supported ...
