SubjectRe: [PATCH] ARM: dts: imx6sl: correct PWM ipg clock source
[Cc: += linux-pwm]

I assume this is related to the patch "pwm: imx: add ipg clock
operation"? This patch doesn't fix a real problem because in practise
perclk is already enabled, right? (I don't question the patch, just
wonder how urgent it is.)

It's a bit irritating that IMX6SL_CLK_PERCLK is used for the "ipg" clk,
not the "per" clk. Is this correct?
