From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx> This series removes the legacy timer code from mach-davinci in favor of a new clocksource driver it introduces. The first patch fixes a device tree bug that's been around for a while. Unfortunately any systems shipped with the buggy device will stop booting once they switch to the new clocksource driver. Patch 2 adds a new clocksource driver for davinci. Patch 3 enables the new driver for device-tree based systems. Patch 4 adds a WARN_ON() to the machine code of all davinci boards which is triggered if clk_get() for the timer clock fails. This is needed as the new driver expects the clock to be functional and doesn't check it. Patches 5-6 and 8-11 switch the board files to using the new clocksource driver while patch 7 moves some necessary defines to a different place since we'll be removing the file that contains them. Patch 12 removes legacy timer code. v1 -> v2: - changed the license to GPL-only - dropped regmap usage due to the additional code paths making the code too slow - minor code rearrangement - fixed the da830 timer configuration - correctly assign the timer halfs to clocksource and clockevent - sqashed the commits adding WARN() when clk_get() fails - used WARN_ON() and added a return when clk_get() fails to avoid entering the timer driver without a valid clock - request the register range before iomapping it - simplified the configuration structure (dropped the additional cmp struct) Bartosz Golaszewski (12): ARM: dts: da850: fix interrupt numbers for clocksource clocksource: davinci-timer: new driver ARM: davinci: enable the clocksource driver for DT mode ARM: davinci: WARN_ON() if clk_get() fails ARM: davinci: da850: switch to using the clocksource driver ARM: davinci: da830: switch to using the clocksource driver ARM: davinci: move timer definitions to davinci.h ARM: davinci: dm355: switch to using the clocksource driver ARM: davinci: dm365: switch to using the clocksource driver ARM: davinci: dm644x: switch to using the clocksource driver ARM: davinci: dm646x: switch to using the clocksource driver ARM: davinci: remove legacy timer support arch/arm/Kconfig | 1 + arch/arm/boot/dts/da850.dtsi | 2 +- arch/arm/mach-davinci/Makefile | 3 +- arch/arm/mach-davinci/da830.c | 53 ++- arch/arm/mach-davinci/da850.c | 60 ++- arch/arm/mach-davinci/davinci.h | 3 + arch/arm/mach-davinci/devices-da8xx.c | 1 - arch/arm/mach-davinci/devices.c | 19 - arch/arm/mach-davinci/dm355.c | 40 +- arch/arm/mach-davinci/dm365.c | 34 +- arch/arm/mach-davinci/dm644x.c | 40 +- arch/arm/mach-davinci/dm646x.c | 40 +- arch/arm/mach-davinci/include/mach/common.h | 17 - arch/arm/mach-davinci/include/mach/time.h | 35 -- arch/arm/mach-davinci/time.c | 414 ------------------- drivers/clocksource/Kconfig | 5 + drivers/clocksource/Makefile | 1 + drivers/clocksource/timer-davinci.c | 431 ++++++++++++++++++++ include/clocksource/timer-davinci.h | 44 ++ 19 files changed, 647 insertions(+), 596 deletions(-) delete mode 100644 arch/arm/mach-davinci/include/mach/time.h delete mode 100644 arch/arm/mach-davinci/time.c create mode 100644 drivers/clocksource/timer-davinci.c create mode 100644 include/clocksource/timer-davinci.h -- 2.20.1
