   8 commit cfe1580a6415bc37fd62d79eb8102a618f7650b2 upstream.

  10 commit 55ee7017ee31 ("arm: omap2: board-generic: use omap4_local_timer_init
  11 for AM437x") makes synctimer32k as the clocksource on AM43xx. By default
  12 the synctimer32k is clocked by 32K RTC OSC on AM43xx. But this 32K RTC OSC
  13 is not available on epos boards which makes it fail to boot.
  14
  15 Synctimer32k can also be clocked by a peripheral PLL, so making this as
  16 clock parent for synctimer3k on epos boards.
