Pull timer updates from Thomas Gleixner: "The timer department delivers the following christmas presents: Core code: - Use proper seqcount initializer to make lockdep happy - SPDX annotations and cleanup of license boilerplates - Use DEFINE_SHOW_ATTRIBUTE() instead of open coding it - Minor cleanups Driver code: - Add the sched_clock for the arc timer (Alexey Brodkin) - Change the file timer names for riscv, rockchip, tegra20, sun4i and meson6 (Daniel Lezcano) - Add the DT bindings for r8a7796, r8a77470 and r8a774a1 (Biju Das) - Remove the early platform driver registration for timer-ti-dm (Bartosz Golaszewski) - Provide the sched_clock for the riscv timer (Anup Patel) - Add support for ARM64 for the imx-gpt and convert the imx-tpm to the timer-of API (Anson Huang) - Remove useless irq protection for the imx-gpt (Clément Péron) - Remove a duplicate function name for the vt8500 (Dan Carpenter) - Remove obsolete inclusion of <asm/smp_twd.h> for the tegra20 (Geert Uytterhoeven) - Demote the prcmu and the custom sched_clock for the dbx500 and the ux500 (Linus Walleij) - Add a new timer clock for the RDA8810PL (Manivannan Sadhasivam) - Rename the macro to stick to the register name and add the delay timer (Martin Blumenstingl) - Switch the bcm2835 to the SPDX identifier (Stefan Wahren) - Fix the interrupt register access on the fttmr010 (Tao Ren) - Add missing of_node_put in the initialization path on the integrator-ap (Yangtao Li)" * 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (39 commits) dt-bindings: timer: Document RDA8810PL SoC timer clocksource/drivers/rda: Add clock driver for RDA8810PL SoC clocksource/drivers/meson6: Change name meson6_timer timer-meson6 clocksource/drivers/sun4i: Change name sun4i_timer to timer-sun4i clocksource/drivers/tegra20: Change name tegra20_timer to timer-tegra20 clocksource/drivers/rockchip: Change name rockchip_timer to timer-rockchip clocksource/drivers/riscv: Change name riscv_timer to timer-riscv clocksource/drivers/riscv_timer: Provide the sched_clock clocksource/drivers/timer-imx-tpm: Specify clock name for timer-of clocksource/drivers/fttmr010: Fix invalid interrupt register access clocksource/drivers/integrator-ap: Add missing of_node_put() clocksource/drivers/bcm2835: Switch to SPDX identifier dt-bindings: timer: renesas, cmt: Document r8a774a1 CMT support clocksource/drivers/timer-imx-tpm: Convert the driver to timer-of clocksource/drivers/arc_timer: Utilize generic sched_clock dt-bindings: timer: renesas, cmt: Document r8a77470 CMT support dt-bindings: timer: renesas, cmt: Document r8a7796 CMT support clocksource/drivers/imx-gpt: Remove unnecessary irq protection clocksource/drivers/imx-gpt: Add support for ARM64 clocksource/drivers/meson6_timer: Implement the ARM delay timer ...
