Hi all,
i.MX27's usb needs three clocks (usb_ipg_gate, usb_ahb_gate and usb_div)
but the current chipidea driver implementation, and devicetree, provides
only ipg and ahb. Consequently, if the bootloader don't enable the last
one, the kernel will crash.
Our approach/idea is to add a second, optionnal, clock in ci_hdrc_imx.c
with 'per' name in devicetree and to add clock name 'main_clk' for mandatory clock.
This approach it correct? Or an other approach seems better?
Thank you very much for your point of view.
Regards,
Philippe and Gwenhael
