An all i.mx, but not on imx6, both clocks are the same, the bug doesn't show up. So before we can use the 24 MHz clock on mx53, we have to fix the driver. Feel free to add my Acked-by to the first patch and take it via your tree. >> [1] On i.MX6 the following patch is needed (which is already in Shawn's >> for-next): >> >> 9b3d423 ARM: i.MX6q: fix the wrong parent of can_root clock > > This one already hits mainline. But not net-next/master, which is my upstream.
