From 2dc6c6f15da97cb3e810963c80e981f19d42cd7d Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 21 May 2010 03:12:44 +0200 Subject: [ARM] pata_pxa: DMA-capable PATA driver This patch adds a driver for a harddrive attached to PXA address and data bus. Unlike pata_platform, this driver allows usage of PXA DMA controller, making the transmission speed 3x higher.

The spitz.c file contained terrible mess and needed a cleanup, here it is: 1) Made every part modular, components are not built in if not selected. 2) Removed loads of preprocessor goo, mostly "#ifdef MACH_AKITA .... #endif" and similar code. The kernel size will grow by a few kb now, but the file is much more readable. 3) Reworked SD/CF power setting function and made it reentrant. 4) Add ISL6271A regulator support 5) Correctly register WM8750 Signed-off-by: Marek Vasut --- arch/arm/mach-pxa/include/mach/spitz.h | 6 + arch/arm/mach-pxa/spitz.c | 474 +++++++++++++++++++++------------ 2 files changed, 311 insertions(+), 169 deletions(-) (limited to 'arch/arm/mach-pxa/include/mach') diff --git a/arch/arm/mach-pxa/include/mach/spitz.h b/arch/arm/mach-pxa/include/mach/spitz.h index dc1ff254229..685749a51c4 100644 --- a/arch/arm/mach-pxa/include/mach/spitz.h +++ b/arch/arm/mach-pxa/include/mach/spitz.h @@ -181,3 +181,9 @@ #define SPITZ_IRQ_GPIO_CF2_IRQ IRQ_GPIO(SPITZ_GPIO_CF2_IRQ) #define SPITZ_IRQ_GPIO_nSD_INT IRQ_GPIO(SPITZ_GPIO_nSD_INT) #define SPITZ_IRQ_GPIO_nSD_DETECT IRQ_GPIO(SPITZ_GPIO_nSD_DETECT) + +/* + * Shared data structures + */ +extern struct platform_device spitzssp_device;
