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. The patch set is based on v3.12-rc1 and further depends on a topic branch created by Stephen Warren for mach-tegra [3]. It is now split into preparation and removal patches to not break bisectability. I added all Acked-by/Tested-by's where applicable or dropped them, if the patch was separated into two. It has been compile tested for all machs involved with the following defconfigs (multi_v7, bcm2835, dove, exynos, kirkwood, mxs, nhk8815) and nspire selected on multi_v4_v5. Patches 1-8 comprise preparation patches that convert machs nomadik, prima2, socfpga, sunxi, tegra, and vt8500 to usual .init_time callbacks calling only of_clk_init and clocksource_of_init. Patch 9 then introduces of_clk_init(NULL) to the arch-wide default .init_time callback. Patches 10-26 finally remove custom .init_time callbacks from the machs involved. The patches have been pushed to a topic branch based on v3.12-rc1 with tegra's tegra-for-3.13-deps-for-arm-init-time-cleanup branch merged in to https://github.com/shesselba/linux-dove.git clk-of-init-v1_for-3.13 [1] http://www.spinics.net/lists/arm-kernel/msg268260.html [2] http://www.spinics.net/lists/arm-kernel/msg270173.html [3] http://www.spinics.net/lists/arm-kernel/msg273957.html git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra.git tegra-for-3.13-deps-for-arm-init-time-cleanup Sebastian Hesselbarth (26): ARM: nomadik: move mtu setup to clocksource init clk: nomadik: move src init out of nomadik_clk_init clk: nomadik: declare OF clock provider clk: prima2: declare OF clock provider ARM: socfgpa: prepare for arch-wide .init_time callback clk: sunxi: declare OF clock provider clk: vt8500: parse pmc_base from clock driver ARM: vt8500: prepare for arch-wide .init_time callback ARM: call of_clk_init from default time_init handler ARM: bcm2835: remove custom .init_time hook ARM: dove: remove custom .init_time hook ARM: exynos: remove custom .init_time hook ARM: highbank: remove custom .init_time hook ARM: imx: remove custom .init_time hook ARM: kirkwood: remove custom .init_time hook ARM: mxs: remove custom .init_time hook ARM: nomadik: remove custom .init_time hook ARM: nspire: remove custom .init_time hook ARM: prima2: remove custom .init_time hook ARM: rockchip: remove custom .init_time hook ARM: socfpga: remove custom .init_time hook ARM: sti: remove custom .init_time hook ARM: sunxi: remove custom .init_time hook ARM: tegra: remove custom .init_time hook ARM: vexpress: remove custom .init_time hook ARM: vt8500: remove custom .init_time hook arch/arm/kernel/time.c | 27 ++--- arch/arm/mach-bcm2835/bcm2835.c | 2 - arch/arm/mach-dove/board-dt.c | 11 -- arch/arm/mach-exynos/common.c | 8 -- arch/arm/mach-exynos/common.h | 1 - arch/arm/mach-exynos/mach-exynos4-dt.c | 2 - arch/arm/mach-exynos/mach-exynos5-dt.c | 2 - arch/arm/mach-highbank/highbank.c | 23 ++--- arch/arm/mach-imx/clk-imx51-imx53.c | 29 ++---- arch/arm/mach-imx/common.h | 4 - arch/arm/mach-imx/imx51-dt.c | 6 -- arch/arm/mach-imx/mach-imx53.c | 6 -- arch/arm/mach-imx/mach-imx6q.c | 14 +-- arch/arm/mach-imx/mach-imx6sl.c | 7 -- arch/arm/mach-imx/mach-vf610.c | 9 -- arch/arm/mach-kirkwood/board-dt.c | 8 -- arch/arm/mach-mxs/mach-mxs.c | 13 --- arch/arm/mach-nomadik/cpu-8815.c | 36 ------- arch/arm/mach-nspire/nspire.c | 9 -- arch/arm/mach-prima2/common.c | 11 -- arch/arm/mach-prima2/common.h | 1 - arch/arm/mach-rockchip/rockchip.c | 9 -- arch/arm/mach-socfpga/socfpga.c | 2 - arch/arm/mach-sti/board-dt.c | 10 +- arch/arm/mach-sunxi/sunxi.c | 10 -- arch/arm/mach-tegra/tegra.c | 9 -- arch/arm/mach-vexpress/v2m.c | 14 +-- arch/arm/mach-vt8500/common.h | 24 ----- arch/arm/mach-vt8500/vt8500.c | 6 -- drivers/clk/clk-bcm2835.c | 8 -- drivers/clk/clk-highbank.c | 10 +- drivers/clk/clk-nomadik.c | 161 ++++++++++++++--------------- drivers/clk/clk-prima2.c | 29 ++---- drivers/clk/clk-vt8500.c | 31 ++++-- drivers/clk/mxs/clk-imx23.c | 15 +-- drivers/clk/mxs/clk-imx28.c | 16 +-- drivers/clk/sunxi/clk-sunxi.c | 11 +- drivers/clocksource/nomadik-mtu.c | 11 ++ include/linux/clk/mxs.h | 2 - include/linux/clk/sunxi.h | 22 ---- include/linux/platform_data/clk-nomadik.h | 2 - 41 files changed, 182 insertions(+), 449 deletions(-) delete mode 100644 arch/arm/mach-vt8500/common.h delete mode 100644 include/linux/clk/sunxi.h delete mode 100644 include/linux/platform_data/clk-nomadik.h --- Cc: Olof Johansson Cc: Arnd Bergmann Cc: Russell King Cc: STEricsson Cc: linux-tegra@vger.kernel.org Cc: linux-rpi-kernel@lists.infradead.org Cc: linux-samsung-soc@vger.kernel.org Cc: kernel@stlinux.com Cc: linux-arm-kernel@lists.infradead.org Cc: linux-kernel@vger.kernel.org -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
