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)"
