Subject: [PATCH v2 1/5] cpufreq: imx-cpufreq-dt: Remove global platform match list
Date: Wed, 5 Jun 2019 13:37:05 +0300 [thread overview]
Message-ID: <d5ce1eb3dec5760d1cf9ea92130f66ddd70a67ce.1559730963.git.leonard.crestez@nxp.com> (raw)
In-Reply-To: <cover.1559730963.git.leonard.crestez@nxp.com>
In-Reply-To: <cover.1559730963.git.leonard.crestez@nxp.com>
This is not currently needed, instead a platform device is always created
from SOC-specific code.
We can use of_machine_is_compatible for per-SOC behavior instead.
