Dear
I am trying to enable the 25MHz clock ENET1_REF_CLK_25M on pad MX6UL_PAD_GPIO1_IO02__ENET1_REF_CLK_25M. I however want this clock to be available as soon as the kernel is booting and this clock must be continuously available. This clock must also be available if fec is disabled.
How can I configure this in the device tree?
Thanks
Pieter
Hi Pieter
clock configuration can be made in uboot function setup_fec()
mx6ul_14x14_evk.c\mx6ul_14x14_evk\freescale\board - uboot-imx - i.MX U-Boot
For enabling clock in linux one can pay attention to gating enet clock settings in
CCM CCM_CCGR3 register.
Best regards
igor
