From 7cdc39eeadf11824b62f65c22de60aca611b0744 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 24 Aug 2012 15:10:04 +0200 Subject: ARM: at91: move platform_data definitions Platform data for device drivers should be defined in include/linux/platform_data/*.h, not in the architecture and platform specific directories. This moves such data out of the at91 include directories Signed-off-by: Arnd Bergmann Acked-by: Mark Brown Acked-by: Greg Kroah-Hartman Acked-by: Nicolas Pitre Acked-by: Nicolas Ferre Acked-by: Vinod Koul Cc: Jean-Christophe Plagniol-Villard Cc: Dan Williams --- include/linux/platform_data/atmel-aes.h | 2 +- include/linux/platform_data/dma-atmel.h | 61 +++++++++++++++++++++++++++++++++ 2 files changed, 62 insertions(+), 1 deletion(-) create mode 100644 include/linux/platform_data/dma-atmel.h (limited to 'include') diff --git a/include/linux/platform_data/atmel-aes.h b/include/linux/platform_data/atmel-aes.h index e7a1949bad26..ab68082fbcb0 100644 --- a/include/linux/platform_data/atmel-aes.h +++ b/include/linux/platform_data/atmel-aes.h @@ -1,7 +1,7 @@ #ifndef __LINUX_ATMEL_AES_H #define __LINUX_ATMEL_AES_H -#include +#include /** * struct aes_dma_data - DMA data for AES diff --git a/include/linux/platform_data/dma-atmel.h b/include/linux/platform_data/dma-atmel.h new file mode 100644 index 000000000000..cab0997be3de --- /dev/null +++ b/include/linux/platform_data/dma-atmel.h @@ -0,0 +1,61 @@ +/* + * Header file for the Atmel AHB DMA Controller driver + * + * Copyright (C) 2008 Atmel Corporation + * + * 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. + */ +#ifndef AT_HDMAC_H +#define AT_HDMAC_H + +#include + +/** + * struct at_dma_platform_data - Controller configuration parameters + * @nr_channels: Number of channels supported by hardware (max 8) + * @cap_mask: dma_capability flags supported by the platform + */ +struct at_dma_platform_data { + unsigned int nr_channels; + dma_cap_mask_t cap_mask; +}; + +/** + * struct at_dma_slave - Controller-specific information about a slave + * @dma_dev: required DMA master device + * @cfg: Platform-specific initializer for the CFG register + */ +struct at_dma_slave { + struct device *dma_dev; + u32 cfg; +}; + + +/* Platform-configurable bits in CFG */ +#define ATC_SRC_PER(h) (0xFU & (h)) /* Channel src rq associated with periph handshaking ifc h */ +#define ATC_DST_PER(h) ((0xFU & (h)) << 4) /* Channel dst rq associated with periph handshaking ifc h */ +#define ATC_SRC_REP (0x1 << 8) /* Source Replay Mod */ +#define ATC_SRC_H2SEL (0x1 << 9) /* Source Handshaking Mod */ +#define ATC_SRC_H2SEL_SW (0x0 << 9) +#define ATC_SRC_H2SEL_HW (0x1 << 9) +#define ATC_DST_REP (0x1 << 12) /* Destination Replay Mod */ +#define ATC_DST_H2SEL (0x1 << 13) /* Destination Handshaking Mod */ +#define ATC_DST_H2SEL_SW (0x0 << 13) +#define ATC_DST_H2SEL_HW (0x1 << 13) +#define ATC_SOD (0x1 << 16) /* Stop On Done */ +#define ATC_LOCK_IF (0x1 << 20) /* Interface Lock */ +#define ATC_LOCK_B (0x1 << 21) /* AHB Bus Lock */ +#define ATC_LOCK_IF_L (0x1 << 22) /* Master Interface Arbiter Lock */ +#define ATC_LOCK_IF_L_CHUNK (0x0 << 22) +#define ATC_LOCK_IF_L_BUFFER (0x1 << 22) +#define ATC_AHB_PROT_MASK (0x7 << 24) /* AHB Protection */ +#define ATC_FIFOCFG_MASK (0x3 << 28) /* FIFO Request Configuration */ +#define ATC_FIFOCFG_LARGESTBURST (0x0 << 28) +#define ATC_FIFOCFG_HALFFIFO (0x1 << 28) +#define ATC_FIFOCFG_ENOUGHSPACE (0x2 << 28) + + +#endif /* AT_HDMAC_H */ -- cgit v1.2.2
