From 34e31d871ee4b6a9f6c5504da7d6dcc24967844c Mon Sep 17 00:00:00 2001 From: Robert Schwebel Date: Tue, 8 Jan 2008 08:44:23 +0100 Subject: [ARM] 4744/1: pcm027: add support for phyCORE-PXA270 CPU module This patch adds main support for the generic phyCORE-PXA270 CPU module (aka PCM-027). Its as generic as possible to support any kind of baseboard. Note: Neither the CPU module nor the pcm027.c implementation can work without a baseboard support. Baseboard support can be added by the PCM-990 or any custom variant. V2: After comments by Eric Miao: - Currently unsupported devices moved into separate patch - direct call of baseboard initialisation V3: After comments by Russell King - sort include files - setting RTC bit for power control removed - style problems fixed (discovered by checkpatch.pl) Signed-off-by: Juergen Beisert Signed-off-by: Russell King --- include/asm-arm/arch-pxa/irqs.h | 10 +++++- include/asm-arm/arch-pxa/pcm027.h | 75 +++++++++++++++++++++++++++++++++++++++ 2 files changed, 84 insertions(+), 1 deletion(-) create mode 100644 include/asm-arm/arch-pxa/pcm027.h (limited to 'include') diff --git a/include/asm-arm/arch-pxa/irqs.h b/include/asm-arm/arch-pxa/irqs.h index b76ee6d1f5b..c562b972a4a 100644 --- a/include/asm-arm/arch-pxa/irqs.h +++ b/include/asm-arm/arch-pxa/irqs.h @@ -180,7 +180,8 @@ #define NR_IRQS (IRQ_LOCOMO_SPI_TEND + 1) #elif defined(CONFIG_ARCH_LUBBOCK) || \ defined(CONFIG_MACH_LOGICPD_PXA270) || \ - defined(CONFIG_MACH_MAINSTONE) + defined(CONFIG_MACH_MAINSTONE) || \ + defined(CONFIG_MACH_PCM027) #define NR_IRQS (IRQ_BOARD_END) #else #define NR_IRQS (IRQ_BOARD_START) @@ -227,6 +228,13 @@ #define IRQ_LOCOMO_LT_BASE (IRQ_BOARD_START + 2) #define IRQ_LOCOMO_SPI_BASE (IRQ_BOARD_START + 3) +/* phyCORE-PXA270 (PCM027) Interrupts */ +#define PCM027_IRQ(x) (IRQ_BOARD_START + (x)) +#define PCM027_BTDET_IRQ PCM027_IRQ(0) +#define PCM027_FF_RI_IRQ PCM027_IRQ(1) +#define PCM027_MMCDET_IRQ PCM027_IRQ(2) +#define PCM027_PM_5V_IRQ PCM027_IRQ(3) + /* ITE8152 irqs */ /* add IT8152 IRQs beyond BOARD_END */ #ifdef CONFIG_PCI_HOST_ITE8152 diff --git a/include/asm-arm/arch-pxa/pcm027.h b/include/asm-arm/arch-pxa/pcm027.h new file mode 100644 index 00000000000..7beae1472c3 --- /dev/null +++ b/include/asm-arm/arch-pxa/pcm027.h @@ -0,0 +1,75 @@ +/* + * linux/include/asm-arm/arch-pxa/pcm027.h + * + * (c) 2003 Phytec Messtechnik GmbH + * (c) 2007 Juergen Beisert + * + * 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; either version 2 of the License, or + * (at your option) any later version. + * + * 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.
