Merge tag 'timers-v7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/daniel.lezcano/linux into timers/clocksource

  - Use designated initializers for sh_mtu2, sh_cmt, and sh_tmu, and
    drop the unused initializer in the platform_device_id table for
    sh_mtu2 (Uwe Kleine-König)

  - Remove redundant dev_err()/dev_err_probe() messages when
    devm_request_*_irq() fails, as the helper already logs an error
    message (Pan Chuang)

  - Fix a boot hang on Allwinner D1 when a forced minimum delta is used
    with the sun4i timer (Felix Yan)

  - Fix an IRQ leak in the cpuhp_setup_state() error path by freeing the
    IRQ on failure in the NXP PIT driver (WenTao Liang)

  - Fix incorrect unmapping of shared MMIO between the clocksource and
    clockevent drivers. If one of them fails to initialize, the error
    path unmaps the shared MMIO region, leaving the other driver with an
    invalid mapping on clps711x (Guangshuo Li)

  - Make the samsung_pwm driver compatible with PREEMPT_RT by replacing
    regular spinlocks with raw_spinlock_t in atomic contexts (Marek
    Szyprowski)

  - Use __raw_readl() and __raw_writel() instead of ioread32() and
    iowrite32() to support SWAP_IO_SPACE in the rtl-otto driver (Rustam
    Adilov)

  - Fix a missing clk_disable_unprepare() call in the timer
    initialization error path of the Armada driver (Yuho Choi)
