Subject: [PATCH 1/8] mach-k3: common: Instantiate AM65 CPSW NUSS wrapper
Date: Fri, 24 Dec 2021 12:55:29 +0530	[thread overview]
Message-ID: <20211224072536.270251-2-vigneshr@ti.com> (raw)
In-Reply-To: <20211224072536.270251-1-vigneshr@ti.com>

Probe toplevel AM65 CPSW NUSS driver from misc_init_r() when driver
is enabled. Since driver is modeled as UCLASS_MISC, we need to
explicitly probe the driver. Use common misc_init_r() that entire
K3 family of SoCs.
