Do we use this 'optclk' in driver?
No we don't. Still the device seems to work without it.
This is supposed to be USB_LFPS_TX_GFCLK or USB3PHY_REF_CLK.
I think it should be enabled. Did you check the status of this clock in
CM_L3INIT_CLKSTCTRL? Moreover USB_LFPS_TX_GFCLK is an interface clock,
so IIUC setting the module mode will enable it.
Btw how did you tell dpll_core_h13x2_ck enables USB_LFPS_TX_GFCLK?
Cheers
Kishon
