Subject: [PATCH v3 1/5] pwm: omap-dmtimer: Drop unused header file
Date: Thu, 12 Mar 2020 09:52:06 +0530	[thread overview]
Message-ID: <20200312042210.17344-2-lokeshvutla@ti.com> (raw)
In-Reply-To: <20200312042210.17344-1-lokeshvutla@ti.com>

pwm_omap_dmtimer.h is used only:
- to typedef struct omap_dm_timer to pwm_omap_dmtimer
- for macro PWM_OMAP_DMTIMER_TRIGGER_OVERFLOW_AND_COMPARE
Rest of the file is pretty mush unsed. So reuse omap_dm_timer
and OMAP_TIMER_TRIGGER_OVERFLOW_AND_COMPARE in pwm-omap-dmtimer.c
and delete the header file.
