Subject: imx8m: soc: Drop disable_pmu_cpu_nodes
X-Git-Url: http://git.dujemihanovic.xyz/img/static/git-favicon.png?a=commitdiff_plain;h=16fc64b5533e97f0eb43e82113e62b236728d23e;p=u-boot.git

imx8m: soc: Drop disable_pmu_cpu_nodes

i.MX8M use PPI for PMU interrupts, there is no reason to update
interrupt-affinity for PMU even interrupt-affinity was wrongly added
to device tree before.
