Hi Thomas,


The following changes since commit d48e0cd8fcaf314175a15d3076d7a1e71bd4e628:

  timekeeping: Boot should be boottime for coarse ns accessor

  Merge branch 'timers/drivers/davinci' into timers/drivers/next
(2019-06-26 16:24:33 +0200)

----------------------------------------------------------------
This version contains the following changes:

 - Rewrite of the davinci timer resulting to an immutable branch to be
   shared with davinci platform specific tree (Bartosz Golaszewski)

 - Cleanup and improvements of the tegra timer (Dmitry Osipenko)

 - Add new nxp system counter timer (Bai Ping)

 - Increase priority for exynos_mct to take over the initialization
   of the IP the arch ARM timer depends on (Marek Szyprowski)

 - Change macro use _BITUL() by BIT() on arc timer (Masahiro Yamada)

 - Implement the delay timer on ixp4xx (Linus Walleij)

 - Add the SPDX license identifier on the meson timer (Neil Armstrong)
