Linux/AM5728: am5728 xref_clk issues with Linux booting

Hi Pavel,

Thanks for the response.

My use case is : XREF_CLK1 -> AHCLKX input. 

I want to use external  xref_clk (6.144 MHz) in order to get ACLKX and AFSX for 8KHz, 16KHz and 48KHz sample rates because my McASP should be master for the external codec. I don't need to have AHCLKX as output.

The funny thing is that when I set abe_sys_clk_div as input for mcasp2_ahclkx_mux in the device tree, Linux boots, and audio works, but it doesn't with ref_clkin1_ck (or with any other xref).

So, how can I configure device tree to clock McASP AHCLKX with the external xref clock? (as described in the last post here: e2e.ti.com/.../1782796

I also set xref_clk1 pin as an input, mode0 (0x298 (PIN_INPUT_PULLUP | MUX_MODE0) /*XREF1 */) but that doesn't solve the problem with kernel panic.

Here is my am57xx-beagle-x15-common.dtsi and kernel printout:
