Subject: ARM: dts: AM33XX: Set pinmux for clkout2 pad used for clock output
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4d9275709649f82dcec157766e86318f6c2c61f6;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ARM: dts: AM33XX: Set pinmux for clkout2 pad used for clock output

xdma_event_intr1.clkout2 pad can be used to source clock
from either 32K OSC or any of the PLL (except MPU) outputs.
On the existing AM335x based boards (EVM, EVM-SK and Bone),
this pad is used to feed the clock to audio codes.

So, this patch configures the pinmux to get clkout2 on the pad.
