From bf2c750b45a57fe120571950f24a5ab9e86a06c3 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Tue, 28 Jun 2011 22:21:57 +0000 Subject: brcm47xx: add initial support for devices with bcma bus. Ethernet and wifi are not working and this is highly experimental. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@27301 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- package/broadcom-diag/src/diag.c | 73 ++++++++++++++----------- package/broadcom-diag/src/gpio.h | 115 ++------------------------------------- 2 files changed, 46 insertions(+), 142 deletions(-) (limited to 'package') diff --git a/package/broadcom-diag/src/diag.c b/package/broadcom-diag/src/diag.c index 00a72e9076..8e7ffa6cc7 100644 --- a/package/broadcom-diag/src/diag.c +++ b/package/broadcom-diag/src/diag.c @@ -149,9 +149,9 @@ static void __init bcm4780_init(void) { /* Enables GPIO 3 that controls HDD and led power on ASUS WL-700gE */ printk(MODULE_NAME ": Spinning up HDD and enabling leds\n"); - gpio_outen(pin, pin); - gpio_control(pin, 0); - gpio_out(pin, pin); + ssb_gpio_outen(&ssb_bcm47xx, pin, pin); + ssb_gpio_control(&ssb_bcm47xx, pin, 0); + ssb_gpio_out(&ssb_bcm47xx, pin, pin); /* Wait 5s, so the HDD can spin up */ set_current_state(TASK_INTERRUPTIBLE); @@ -161,14 +161,14 @@ static void __init bcm4780_init(void) { static void __init NetCenter_init(void) { /* unset pin 6 (+12V) */ int pin = 1 << 6; - gpio_outen(pin, pin); - gpio_control(pin, 0); - gpio_out(pin, pin); + ssb_gpio_outen(&ssb_bcm47xx, pin, pin); + ssb_gpio_control(&ssb_bcm47xx, pin, 0); + ssb_gpio_out(&ssb_bcm47xx, pin, pin); /* unset pin 1 (turn off red led, blue will light alone if +5V comes up) */ pin = 1 << 1; - gpio_outen(pin, pin); - gpio_control(pin, 0); - gpio_out(pin, pin); + ssb_gpio_outen(&ssb_bcm47xx, pin, pin); + ssb_gpio_control(&ssb_bcm47xx, pin, 0); + ssb_gpio_out(&ssb_bcm47xx, pin, pin); /* unset pin 3 (+5V) and wait 5 seconds (harddisk spin up) */ bcm4780_init(); } @@ -177,9 +177,9 @@ static void __init bcm57xx_init(void) { int pin = 1 << 2; /* FIXME: switch comes up, but port mappings/vlans not right */ - gpio_outen(pin, pin); - gpio_control(pin, 0); - gpio_out(pin, pin); + ssb_gpio_outen(&ssb_bcm47xx, pin, pin); + ssb_gpio_control(&ssb_bcm47xx, pin, 0); + ssb_gpio_out(&ssb_bcm47xx, pin, pin); } static struct platform_t __initdata platforms[] = { @@ -1166,18 +1166,18 @@ static void register_buttons(struct button_t *b) platform.button_mask &= ~gpiomask; - gpio_outen(platform.button_mask, 0); - gpio_control(platform.button_mask, 0); - platform.button_polarity = gpio_in() & platform.button_mask; - gpio_intpolarity(platform.button_mask, platform.button_polarity); - gpio_setintmask(platform.button_mask, platform.button_mask); + ssb_gpio_outen(&ssb_bcm47xx, platform.button_mask, 0); + ssb_gpio_control(&ssb_bcm47xx, platform.button_mask, 0); + platform.button_polarity = ssb_gpio_in(&ssb_bcm47xx, ~0) & platform.button_mask; + ssb_gpio_polarity(&ssb_bcm47xx, platform.button_mask, platform.button_polarity); + ssb_gpio_intmask(&ssb_bcm47xx, platform.button_mask, platform.button_mask); gpio_set_irqenable(1, button_handler); } static void unregister_buttons(struct button_t *b) { - gpio_setintmask(platform.button_mask, 0); + ssb_gpio_intmask(&ssb_bcm47xx, platform.button_mask, 0); gpio_set_irqenable(0, button_handler); } @@ -1237,12 +1237,12 @@ static irqreturn_t button_handler(int irq, void *dev_id) struct button_t *b; u32 in, changed; - in = gpio_in() & platform.button_mask; - gpio_intpolarity(platform.button_mask, in); + in = ssb_gpio_in(&ssb_bcm47xx, ~0) & platform.button_mask; + ssb_gpio_polarity(&ssb_bcm47xx, platform.button_mask, in); changed = platform.button_polarity ^ in; platform.button_polarity = in; - changed &= ~gpio_outen(0, 0); + changed &= ~ssb_gpio_outen(&ssb_bcm47xx, 0, 0); for (b = platform.buttons; b->name; b++) { struct event_t *event; @@ -1298,10 +1298,10 @@ static void register_leds(struct led_t *l) } } - gpio_outen(mask, oe_mask); - gpio_control(mask, 0); - gpio_out(mask, val); - gpio_setintmask(mask, 0); + ssb_gpio_outen(&ssb_bcm47xx, mask, oe_mask); + ssb_gpio_control(&ssb_bcm47xx, mask, 0); + ssb_gpio_out(&ssb_bcm47xx, mask, val); + ssb_gpio_intmask(&ssb_bcm47xx, mask, 0); } static void unregister_leds(struct led_t *l) @@ -1336,11 +1336,11 @@ static void led_flash(unsigned long dummy) { mask &= ~gpiomask; if (mask) { - u32 val = ~gpio_in(); + u32 val = ~ssb_gpio_in(&ssb_bcm47xx, ~0); - gpio_outen(mask, mask); - gpio_control(mask, 0); - gpio_out(mask, val); + ssb_gpio_outen(&ssb_bcm47xx, mask, mask); + ssb_gpio_control(&ssb_bcm47xx, mask, 0); + ssb_gpio_out(&ssb_bcm47xx, mask, val); } if (mask || extif_blink) { mod_timer(&led_timer, jiffies + FLASH_TIME); @@ -1367,7 +1367,7 @@ static ssize_t diag_proc_read(struct file *file, char *buf, size_t count, loff_t if (led->gpio & GPIO_TYPE_EXTIF) { len = sprintf(page, "%d\n", led->state); } else { - u32 in = (gpio_in() & led->gpio ?
