    Subject[PATCH 00/17] ARM: davinci: modernize the timer support
    Date
    From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

    This series removes the legacy timer code from mach-davinci in favor of
    a new clocksource driver it introduces.

    The first patch fixes a device tree bug that's been around for a while.
    Unfortunately any systems shipped with the buggy device will stop booting
    once they switch to the new clocksource driver.

    Patch 2 adds a new clocksource driver for davinci.

    Patch 3 enables the new driver for device-tree based systems.

    Patches 4-9 add a WARN() to the machine code of all davinci boards
    which is triggered if clk_get() for the timer clock fails. This is needed
    as the new driver expects the clock to be functional and doesn't check it.

    Patches 10-11 and 13-16 switch the board files to using the new
    clocksource driver while patch 12 moves some necessary defines to
    a different place since we'll be removing the file that contains them.

    Patch 17 removes legacy timer code.
