If SoC dependent, then it should be implied by the SoC specific
compatible. Also, seems like you should add clock binding support here
if you need more clock control.

The clock source selection is done by a register bit inside the IP block:
BIT13 CLKSRC CAN Engine Clock Source
0b - The CAN engine clock source is the oscillator clock.
1b - The CAN engine clock source is the peripheral clock.
Currently it's written 1 by default during driver initialization.
drivers/net/can/flexcan.c
/* select "bus clock", chip must be disabled */
reg = priv->read(®s->ctrl);
reg |= FLEXCAN_CTRL_CLK_SRC;
priv->write(reg, ®s->ctrl);
I'm not sure if it's a typical case to abstract CLKSRC bit into a common clock mux.
(Is there any similar case in kernel?)
But I think we can also use SoC specific compatible to write 0 for those special
Ones (currently only imx8qxp). Then this patch may not be needed.
Marc,
Please let us know if you have a different idea.

Hi,
My expression here might not be very accurate, this property just help to select the clock source for
Protocol Engine (PE). FlexCAN ip support two PE clock sources, so we have to add this property to
let driver know that SoC has selected which one.

Add support to select the clock source for CAN Protocol Engine (PE).
It's Soc Implementation dependent. Refer to RM for detailed definition
of each Soc. We select clock source 1 (peripheral clock) by default in
driver now, this patch add support to prase clock source in DTS file.
