From eff443df679ea7e553830db992e2f02707ddbb47 Mon Sep 17 00:00:00 2001 From: Janusz Krzysztofik Date: Fri, 28 Aug 2009 10:51:37 -0700 Subject: [PATCH] OMAP1: AMS_DELTA: add modem support This patch adds support for modem device found on Amstrad E3 (Delta) board. Based on earlier patch by Jonathan McDowell, available at http://the.earth.li/pub/e3/2.6.19/ams-delta-modem.patch. Modified after Ladislav Michl's arch/arm/mach-omap1/board-voiceblue.c. This patch is dependent on 8250 driver changes getting accepted upstream: http://git.kernel.org/?p=linux/kernel/git/sfr/linux-next.git;a=commit;h=7053133124d5cdf207c1168c7a0c582a18e12ea7 Signed-off-by: Janusz Krzysztofik Signed-off-by: Tony Lindgren --- arch/arm/mach-omap1/board-ams-delta.c | 38 +++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) diff --git a/arch/arm/mach-omap1/board-ams-delta.c b/arch/arm/mach-omap1/board-ams-delta.c index 5807732..42920f9 100644 --- a/arch/arm/mach-omap1/board-ams-delta.c +++ b/arch/arm/mach-omap1/board-ams-delta.c @@ -15,8 +15,11 @@ #include #include #include +#include #include +#include +#include #include #include #include @@ -230,6 +233,41 @@ static void __init ams_delta_init(void) platform_add_devices(ams_delta_devices, ARRAY_SIZE(ams_delta_devices)); } +static struct plat_serial8250_port ams_delta_modem_ports[] = { + { + .membase = (void *) AMS_DELTA_MODEM_VIRT, + .mapbase = AMS_DELTA_MODEM_PHYS, + .irq = -EINVAL, /* changed later */ + .flags = UPF_BOOT_AUTOCONF, + .irqflags = IRQF_TRIGGER_RISING, + .iotype = UPIO_MEM, + .regshift = 1, + .uartclk = BASE_BAUD * 16, + }, + { }, +}; + +static struct platform_device ams_delta_modem_device = { + .name = "serial8250", + .id = PLAT8250_DEV_PLATFORM1, + .dev = { + .platform_data = ams_delta_modem_ports, + }, +}; + +static int __init ams_delta_modem_init(void) +{ + omap_cfg_reg(M14_1510_GPIO2); + ams_delta_modem_ports[0].irq = gpio_to_irq(2); + + ams_delta_latch2_write( + AMS_DELTA_LATCH2_MODEM_NRESET | AMS_DELTA_LATCH2_MODEM_CODEC, + AMS_DELTA_LATCH2_MODEM_NRESET | AMS_DELTA_LATCH2_MODEM_CODEC); + + return platform_device_register(&ams_delta_modem_device); +} +arch_initcall(ams_delta_modem_init); + static void __init ams_delta_map_io(void) { omap1_map_common_io(); -- 2.7.4
