This patch adds CLK_IGNORE_UNUSED flag to hclk_usb_peri, hclk_usbotg0 and hclk_usbotg1
because these clocks must remain enabled to use the USB controllers in host mode.
This fixes a regression introduced by patch "clk: rockchip: disable unused clocks"

Could you refer the commit id instead ? something like "commit <ID>
("title of the corresponding commit") (and use scripts/checkpatch.pl
on your patch to be sure that the commit form is okay).
I confirm the regression.

This patch adds CLK_IGNORE_UNUSED flag to hclk_usb_peri, hclk_usbotg0
and hclk_usbotg1 because these clocks must remain enabled to use the
USB controllers in host mode.
This fixes a regression introduced by commit 78eaf6095cc7
("clk: rockchip: disable unused clocks").
