This include rt3050, rt3052, -rt3352 and rt5350. These all have a builtin 5 port 100mbit switch. This patch -includes rudimentary code to power up the switch. There are a lot of magic -values that get written to the switch and the internal phys. These values -come straight from the SDK driver and we do not know the meaning of most of -them. - -Signed-off-by: John Crispin <blogic@openwrt.org> -Signed-off-by: Felix Fietkau <nbd@openwrt.org> -Signed-off-by: Michael Lee <igvtee@gmail.com> ---- - drivers/net/ethernet/mediatek/esw_rt3050.c | 18 +--- - drivers/net/ethernet/mediatek/soc_rt3050.c | 158 ++++++++++++++++++++++++++++ - 2 files changed, 159 insertions(+), 17 deletions(-) - create mode 100644 drivers/net/ethernet/mediatek/soc_rt3050.c - ---- a/drivers/net/ethernet/mediatek/esw_rt3050.c -+++ b/drivers/net/ethernet/mediatek/esw_rt3050.c -@@ -14,27 +14,11 @@ - - #include <linux/module.h> - #include <linux/kernel.h> --#include <linux/types.h> --#include <linux/dma-mapping.h> --#include <linux/init.h> --#include <linux/skbuff.h> --#include <linux/etherdevice.h> --#include <linux/ethtool.h> - #include <linux/platform_device.h> --#include <linux/of_device.h> --#include <linux/clk.h> --#include <linux/of_net.h> --#include <linux/of_mdio.h> -- - #include <asm/mach-ralink/ralink_regs.h> - - #include "mtk_eth_soc.h" - --#include <linux/ioport.h> --#include <linux/mii.h> -- --#include <ralink_regs.h> -- - /* HW limitations for this switch: - * - No large frame support (PKT_MAX_LEN at most 1536) - * - Can't have untagged vlan and tagged vlan on one port at the same time, -@@ -559,7 +543,7 @@ static irqreturn_t esw_interrupt(int irq - - static int esw_probe(struct platform_device *pdev) - { -- struct resource *res = platform_get_resource(p, IORESOURCE_MEM, 0); -+ struct resource *res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - struct device_node *np = pdev->dev.of_node; - const __be32 *port_map, *reg_init; - struct rt305x_esw *esw; -@@ -629,12 +613,9 @@ static struct platform_driver esw_driver - }, - }; - --int __init mtk_switch_init(void) --{ -- return platform_driver_register(&esw_driver); --} -+module_platform_driver(esw_driver); - --void mtk_switch_exit(void) --{ -- platform_driver_unregister(&esw_driver); --} -+MODULE_LICENSE("GPL"); -+MODULE_AUTHOR("John Crispin <blogic@openwrt.org>"); -+MODULE_DESCRIPTION("Switch driver for RT305X SoC"); -+MODULE_VERSION(MTK_FE_DRV_VERSION); ---- /dev/null -+++ b/drivers/net/ethernet/mediatek/soc_rt3050.c -@@ -0,0 +1,158 @@ -+/* This program is free software; you can redistribute it and/or modify -+ * it under the terms of the GNU General Public License as published by -+ * the Free Software Foundation; version 2 of the License -+ * -+ * This program is distributed in the hope that it will be useful, -+ * but WITHOUT ANY WARRANTY; without even the implied warranty of -+ * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
