From a08f2f7b944f6926843b26a216db58b8d02a19e1 Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Mon, 8 Jun 2020 11:27:19 +0200 Subject: [PATCH] net: dwc_eth_qos: add Kconfig option to select supported configuration Add configuration flag to select the supported dwc driver configuration: - CONFIG_DWC_ETH_QOS_TEGRA186 - CONFIG_DWC_ETH_QOS_IMX - CONFIG_DWC_ETH_QOS_STM32 See Linux driver ethernet/stmicro/stmmac and associated glue layers for other configuration examples. This patch removes the not-selected compatibles and lets the linker remove the unused functions to reduce the size of the driver.
