Merge branch 'clk-of-init-v2_for-3.13' of https://github.com/shesselba/linux-dove into next/cleanup
From Sebastian Hasselbarth: This is a patch set based on an RFC [1][2] sent earlier to provide a common arch/arm init for DT clock providers. Currently, the call to of_clk_init(NULL) to initialize DT clock providers is spread among several mach-dirs. Since most machs require DT clocks initialized before timers, no initcall can be used. By adding of_clk_init(NULL) to arch/arm time_init(), we can remove all mach-specific .init_time hooks that basically called of_clk_init and clocksource_of_init. In contrast to the RFC version, of_clk_init(NULL) is now only called if no custom .init_time callback is set. This allows some machs to still call clock init themselves, as not all can be converted now. Therefore, this patch sets drops conversion of mach-mvebu and mach-zynq. New machs that were introduced with v3.12-rc1 are also converted, except mach-u300 that requires clocks before irqs. * 'clk-of-init-v2_for-3.13' of https://github.com/shesselba/linux-dove: (29 commits) ARM: vt8500: remove custom .init_time hook ARM: vexpress: remove custom .init_time hook ARM: tegra: remove custom .init_time hook ARM: sunxi: remove custom .init_time hook ARM: sti: remove custom .init_time hook ARM: socfpga: remove custom .init_time hook ARM: rockchip: remove custom .init_time hook ARM: prima2: remove custom .init_time hook ARM: nspire: remove custom .init_time hook ARM: nomadik: remove custom .init_time hook ARM: mxs: remove custom .init_time hook ARM: kirkwood: remove custom .init_time hook ARM: imx: remove custom .init_time hook ARM: highbank: remove custom .init_time hook ARM: exynos: remove custom .init_time hook ARM: dove: remove custom .init_time hook ARM: bcm2835: remove custom .init_time hook ARM: bcm: provide common arch init for DT clocks ARM: call of_clk_init from default time_init handler ARM: vt8500: prepare for arch-wide .init_time callback ...
