Merge tag 'timers-v7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/daniel.lezcano/linux into timers/clocksource

  - Added the DT bindings for the compatible string 'fsl,imx25-epit'
    (Frank Li)

  - Made the rttm_cs variable static for the rtl otto timer driver
    (Krzysztof Kozlowski)

  - Fixed error return code handling in the sun5i timer driver (Chen Ni)

  - Made the timer-of and the mmio code compatible with modules (Daniel
    Lezcano)
