Merge tag 'omap-for-v4.15/soc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc
Pull "OMAP soc changes for omaps for v4.15 merge window" from Tony Lindgren: SoC changes for omaps for v4.15 merge window that are mostly non-urgent fixes and clean-up in preparation for dropping more platform data later on: - Fix am33xx/am437x MMC address space offsets - Fix overwriting clkctrl and modulemode values when dts data is used - Drop unused platform init code for omap_init_hdq - Drop unused struct omap_hwmod_mux_info - Remove duplicate define for dra722 es1.0 silicon revision - Add support for dra71x es2.1 - Make omap_dma_dev_info __initdata - A series of fixes for Coccinelle found issues * tag 'omap-for-v4.15/soc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP: Fix typos in two comment lines in _omap_dm_timer_request() ARM: OMAP: Use kcalloc() in omap_system_dma_probe() ARM: OMAP: Improve a size determination in two functions ARM: OMAP: Delete an error message for a failed memory allocation in two functions ARM: OMAP2+: make omap_dma_dev_info __initdata ARM: DRA722: Add support for DRA71x Silicon Rev 2.1 ARM: DRA722: remove redundant definition of 1.0 device ARM: OMAP2+: Drop unused omap_hwmod_mux_info ARM: OMAP2+: Drop unused omap_init_hdq ARM: OMAP2+: Fix overwriting of clkctrl and modulemode values ARM: OMAP2+: Fix MMC address space mismatch for am33xx and am43xx
