Subject: [PATCH] clk: rockchip: add CLK_IGNORE_UNUSED flag to fix USB Host

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.

I can also fix this up when applying the patch

instead of prose-confirmation please provide appropriate tags, like
