imx287 SAIF1_MCLK as general purpose clock

I would know if it's possible with imx287 custom board to drive SAIF1_MCLK gpio (pin GPMI_CE3N) as general purpose clock with frequency about 4-5 KHz.

What's the configuration I need to deploy during kernel startup? Working with kernel I've applied a similar initialitiation that I found into audio_clk_init() function (source file mach-mx28/device.c) but it didn't work.
