    Subject[PATCH AUTOSEL 5.6 278/606] clk: ti: am33xx: fix RTC clock parent
    Date
    From: Tero Kristo <t-kristo@ti.com>

    [ Upstream commit dc6dbd51009fc412729c307161f442c0a08618f4 ]

    Right now, trying to use RTC purely with the ti-sysc / clkctrl framework
    fails to enable the RTC module properly. Based on experimentation, this
    appears to be because RTC is sourced from the clkdiv32k optional clock.
    TRM is not very clear on this topic, but fix the RTC to use the proper
    source clock nevertheless.
