From 7074bb286de24b9e9c8a1fd159bbabe69442ebf6 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Wed, 30 Oct 2013 06:50:52 +0000 Subject: ar71xx: add kernel support for DRAGINO2 This patch adds support for DRAGINO2 board (used by Meshpotato v2). Most of the files included can be found in the official svn repository provided by the company [1]. I have just adapt it to the last OpenWrt trunk revision (Fri Oct 4 10:49:47 2013). 1. http://svn.dragino.com/dragino2 Patchwork: http://patchwork.openwrt.org/patch/4234/ Signed-off-by: Pau Escrich [juhosg: - rename and refresh kernel patch, - fix checkpatch warnings in mach-dragino2.c] Signed-off-by: Gabor Juhos SVN-Revision: 38587 --- .../ar71xx/files/arch/mips/ath79/mach-dragino2.c | 127 +++++++++++++++++++++ 1 file changed, 127 insertions(+) create mode 100644 target/linux/ar71xx/files/arch/mips/ath79/mach-dragino2.c (limited to 'target/linux/ar71xx/files/arch/mips/ath79/mach-dragino2.c') diff --git a/target/linux/ar71xx/files/arch/mips/ath79/mach-dragino2.c b/target/linux/ar71xx/files/arch/mips/ath79/mach-dragino2.c new file mode 100644 index 0000000000..156fbe50eb --- /dev/null +++ b/target/linux/ar71xx/files/arch/mips/ath79/mach-dragino2.c @@ -0,0 +1,127 @@ +/* + * DRAGINO V2 board support, based on Atheros AP121 board support + * + * Copyright (C) 2011-2012 Gabor Juhos + * Copyright (C) 2012 Elektra Wagenrad + * + * This program is free software; you can redistribute it and/or modify it + * under the terms of the GNU General Public License version 2 as published + * by the Free Software Foundation. + */ + +#include +#include +#include +#include "common.h" +#include "dev-eth.h" +#include "dev-gpio-buttons.h" +#include "dev-leds-gpio.h" +#include "dev-m25p80.h" +#include "dev-spi.h" +#include "dev-usb.h" +#include "dev-wmac.h" +#include "machtypes.h" + +#define DRAGINO2_GPIO_LED_WLAN 0 +#define DRAGINO2_GPIO_LED_LAN 13 +#define DRAGINO2_GPIO_LED_WAN 17 + +/* + * The following GPIO is actually named "Router" on the board. + * However, since the "Router" feature is not supported as of yet + * we use it to display USB activity. + */ + +#define DRAGINO2_GPIO_LED_USB 28 +#define DRAGINO2_GPIO_BTN_JUMPSTART 11 +#define DRAGINO2_GPIO_BTN_RESET 12 + +#define DRAGINO2_KEYS_POLL_INTERVAL 20 /* msecs */ +#define DRAGINO2_KEYS_DEBOUNCE_INTERVAL (3 * DRAGINO2_KEYS_POLL_INTERVAL) + +#define DRAGINO2_MAC0_OFFSET 0x0000 +#define DRAGINO2_MAC1_OFFSET 0x0006 +#define DRAGINO2_CALDATA_OFFSET 0x1000 +#define DRAGINO2_WMAC_MAC_OFFSET 0x1002 + +static struct gpio_led dragino2_leds_gpio[] __initdata = { + { + .name = "dragino2:red:lan", + .gpio = DRAGINO2_GPIO_LED_LAN, + .active_low = 0, + }, + { + .name = "dragino2:red:wlan", + .gpio = DRAGINO2_GPIO_LED_WLAN, + .active_low = 0, + }, + { + .name = "dragino2:red:wan", + .gpio = DRAGINO2_GPIO_LED_WAN, + .active_low = 0, + }, + { + .name = "dragino2:red:usb", + .gpio = DRAGINO2_GPIO_LED_USB, + .active_low = 0, + }, +}; + +static struct gpio_keys_button dragino2_gpio_keys[] __initdata = { + { + .desc = "jumpstart button", + .type = EV_KEY, + .code = KEY_WPS_BUTTON, + .debounce_interval = DRAGINO2_KEYS_DEBOUNCE_INTERVAL, + .gpio = DRAGINO2_GPIO_BTN_JUMPSTART, + .active_low = 1, + }, + { + .desc = "reset button", + .type = EV_KEY, + .code = KEY_RESTART, + .debounce_interval = DRAGINO2_KEYS_DEBOUNCE_INTERVAL, + .gpio = DRAGINO2_GPIO_BTN_RESET, + .active_low = 1, + } +}; + +static void __init dragino2_common_setup(void) +{ + u8 *art = (u8 *) KSEG1ADDR(0x1fff0000); + + ath79_register_m25p80(NULL); + ath79_register_wmac(art + DRAGINO2_CALDATA_OFFSET, + art + DRAGINO2_WMAC_MAC_OFFSET); + + ath79_init_mac(ath79_eth0_data.mac_addr, art + DRAGINO2_MAC0_OFFSET, 0); + ath79_init_mac(ath79_eth1_data.mac_addr, art + DRAGINO2_MAC1_OFFSET, 0); + + ath79_register_mdio(0, 0x0); + + /* Enable GPIO15 and GPIO16 and possibly GPIO26 and GPIO27 */ + ath79_gpio_function_disable(AR933X_GPIO_FUNC_ETH_SWITCH_LED2_EN | + AR933X_GPIO_FUNC_ETH_SWITCH_LED3_EN); + + /* LAN ports */ + ath79_register_eth(1); + + /* WAN port */ + ath79_register_eth(0); +} + +static void __init dragino2_setup(void) +{ + dragino2_common_setup(); + + ath79_register_leds_gpio(-1, ARRAY_SIZE(dragino2_leds_gpio), + dragino2_leds_gpio); + ath79_register_gpio_keys_polled(-1, DRAGINO2_KEYS_POLL_INTERVAL, + ARRAY_SIZE(dragino2_gpio_keys), + dragino2_gpio_keys); + ath79_register_usb(); +} + +MIPS_MACHINE(ATH79_MACH_DRAGINO2, "DRAGINO2", "Dragino Dragino v2", + dragino2_setup); + -- cgit v1.2.3
