Merge tag 'omap-for-v4.17/timer-signed' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc
Pull "Move omap timer to drivers for 4.17" from Tony Lindgren: This series from Keerthy and Ladislav Michl move omap dmtimer code to drivers. As we don't want to export custom timer functions to random drivers, we also need to update the related PWM driver to pass the timer specific functions in platform data. Note that this series is based on a merge of omap1 specific timer fix and omap2+ platform data clean-up to keep things working and make the move a bit simpler. * tag 'omap-for-v4.17/timer-signed' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: clocksource: timer-ti-dm: Check prescaler value clocksource: timer-ti-dm: Consolidate set source clocksource: timer-ti-dm: Make unexported functions static ARM: OMAP: pdata-quirks: Remove unused timer pdata pwm: pwm-omap-dmtimer: Adapt driver to utilize dmtimer pdata ops clocksource: timer-ti-dm: Hook device platform data if not already assigned clocksource: timer-ti-dm: Populate the timer ops to the pdata clocksource: timer-ti-dm: Add timer ops to the platform data structure ARM: OMAP: Move dmtimer driver out of plat-omap to drivers under clocksource clocksource: timer-ti-dm: Replace architecture ARM: OMAP: Move dmtimer.h out of plat-omap ARM: OMAP: timer: Wrap the inline functions under OMAP2PLUS define ARM: OMAP: dmtimer: Remove all the exports ARM: OMAP: Fix dmtimer init for omap1
