X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ad8dfac66fb1995014060302bda19a15bc62bd6d;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

arm/dts: OMAP4: Add a main ocp entry bound to l3-noc driver

Used the main OCP node to add bindings with the l3_noc driver.
Remove l3_noc static device creation if DT is populated.
