The VBATTB controller controls the clock for the RTC on the Renesas RZ/G3S. The HW block diagram for the clock logic is as follows: +----------+ XC `\ RTXIN --->| |----->| \ +----+ VBATTCLK | 32K clock| | |----->|gate|-----------> | osc | XBYP | | +----+ RTXOUT --->| |----->| / +----------+ ,/ One could connect as input to this HW block either a crystal or an external clock device. This is board specific. After discussions w/ Stephen Boyd the clock tree associated with this hardware block was exported in Linux as: input-xtal xbyp xc mux vbattclk where: - input-xtal is the input clock (connected to RTXIN, RTXOUT pins) - xc, xbyp are mux inputs - mux is the internal mux - vbattclk is the gate clock that feeds in the end the RTC to allow selecting the input of the MUX though assigned-clock DT properties, using the already existing clock drivers and avoid adding other DT properties. This allows select the input of the mux based on the type of the connected input clock: - if the 32768 crystal is connected as input for the VBATTB, the input of the mux should be xc - if an external clock device is connected as input for the VBATTB the input of the mux should be xbyp Add bindings for the VBATTB controller.
