[PATCH v3 03/18] driver core: platform: Rename platform_dma_configure()

From: Lu Baolu
Date: Sun Dec 05 2021 - 21:00:01 EST


The platform_dma_configure() is shared between platform and amba bus
drivers. Rename the common helper to firmware_dma_configure() so that
both platform and amba bus drivers could customize their dma_configure
callbacks.
