+Subject: [PATCH 1/6] bcm63xx_enet: correct clock usage
+
+Check the return code of prepare_enable and change one last instance of
+enable only to prepare_enable. Also properly disable and release the
+clock in error paths and on remove for enetsw.

+ BCM6345
+
+The DMA controller regs actually point to DMA channel 0, so the write to
+ENETDMA_CFG_REG will actually modify a random DMA channel.
+
+Since DMA controller registers do not exist on BCM6345, guard the write
+with the usual check for dma_has_sram.

+Do not rely on the shared device being probed before the enet(sw)
+devices. This makes it easier to eventually move out the shared
+device as a dma controller driver (what it should be).
