From af75655c066621352c419646ec0775e9523dc720 Mon Sep 17 00:00:00 2001 From: Jamie Iles Date: Mon, 25 Jul 2011 17:36:42 +0100 Subject: picoxcell: support for Picochip picoxcell devices picoXcell is a family of femtocell devices with an ARM application processor and picoArray DSP processor array. This patch adds support for picoXcell boards to be booted using the device tree registering the VIC's, UART's and timers. v3: - fixup vic compatible string in binding v2: - cleanup empty mach headers - convert to of_platform_populate() - simplify uncompress.h - split vic node into 2 devices - add missing __initconst attributes Signed-off-by: Jamie Iles --- arch/arm/mach-picoxcell/common.c | 55 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 55 insertions(+) create mode 100644 arch/arm/mach-picoxcell/common.c (limited to 'arch/arm/mach-picoxcell/common.c') diff --git a/arch/arm/mach-picoxcell/common.c b/arch/arm/mach-picoxcell/common.c new file mode 100644 index 00000000000..34d08347be5 --- /dev/null +++ b/arch/arm/mach-picoxcell/common.c @@ -0,0 +1,55 @@ +/* + * Copyright (c) 2011 Picochip Ltd., Jamie Iles + * + * 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. + * + * All enquiries to support@picochip.com + */ +#include +#include +#include +#include +#include + +#include +#include + +#include +#include + +#include "common.h" + +static void __init picoxcell_init_machine(void) +{ + of_platform_populate(NULL, of_default_bus_match_table, NULL, NULL); +} + +static const char *picoxcell_dt_match[] = { + "picochip,pc3x2", + "picochip,pc3x3", + NULL +}; + +static const struct of_device_id vic_of_match[] __initconst = { + { .compatible = "arm,pl192-vic" }, + { /* Sentinel */ } +}; + +static void __init picoxcell_init_irq(void) +{ + vic_init(IO_ADDRESS(PICOXCELL_VIC0_BASE), 0, ~0, 0); + vic_init(IO_ADDRESS(PICOXCELL_VIC1_BASE), 32, ~0, 0); + irq_domain_generate_simple(vic_of_match, PICOXCELL_VIC0_BASE, 0); + irq_domain_generate_simple(vic_of_match, PICOXCELL_VIC1_BASE, 32); +} + +DT_MACHINE_START(PICOXCELL, "Picochip picoXcell") + .map_io = picoxcell_map_io, + .nr_irqs = ARCH_NR_IRQS, + .init_irq = picoxcell_init_irq, + .timer = &picoxcell_timer, + .init_machine = picoxcell_init_machine, + .dt_compat = picoxcell_dt_match, +MACHINE_END -- cgit v1.2.3-70-g09d2
