From 92558d67a463bfbb351d30e28648de03b635f024 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 6 Sep 2007 16:27:37 +0000 Subject: strip the kernel version suffix from target directories, except for brcm-2.4 (the -2.4 will be included in the board name here). CONFIG_LINUX__ becomes CONFIG_TARGET_, same for profiles. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@8653 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- .../rb532/files/include/asm-mips/rc32434/dma_v.h | 72 ++++++++++++++++++++++ 1 file changed, 72 insertions(+) create mode 100644 target/linux/rb532/files/include/asm-mips/rc32434/dma_v.h (limited to 'target/linux/rb532/files/include/asm-mips/rc32434/dma_v.h') diff --git a/target/linux/rb532/files/include/asm-mips/rc32434/dma_v.h b/target/linux/rb532/files/include/asm-mips/rc32434/dma_v.h new file mode 100644 index 0000000000..81cb40505d --- /dev/null +++ b/target/linux/rb532/files/include/asm-mips/rc32434/dma_v.h @@ -0,0 +1,72 @@ +#ifndef __IDT_DMA_V_H__ +#define __IDT_DMA_V_H__ + +/******************************************************************************* + * + * Copyright 2002 Integrated Device Technology, Inc. + * All rights reserved. + * + * DMA register definition. + * + * File : $Id: dma.h,v 1.3 2002/06/06 18:34:03 astichte Exp $ + * + * Author : ryan.holmQVist@idt.com + * Date : 20011005 + * Update : + * $Log: dma.h,v $ + * Revision 1.3 2002/06/06 18:34:03 astichte + * Added XXX_PhysicalAddress and XXX_VirtualAddress + * + * Revision 1.2 2002/06/05 18:30:46 astichte + * Removed IDTField + * + * Revision 1.1 2002/05/29 17:33:21 sysarch + * jba File moved from vcode/include/idt/acacia + * + * + ******************************************************************************/ +#include +#include +#define DMA_CHAN_OFFSET 0x14 +#define IS_DMA_USED(X) (((X) & (DMAD_f_m | DMAD_d_m | DMAD_t_m)) != 0) +#define DMA_COUNT(count) \ + ((count) & DMAD_count_m) + +#define DMA_HALT_TIMEOUT 500 + + +static inline int rc32434_halt_dma(DMA_Chan_t ch) +{ + int timeout=1; + if (local_readl(&ch->dmac) & DMAC_run_m) { + local_writel(0, &ch->dmac); + for (timeout = DMA_HALT_TIMEOUT; timeout > 0; timeout--) { + if (local_readl(&ch->dmas) & DMAS_h_m) { + local_writel(0, &ch->dmas); + break; + } + } + } + + return timeout ? 0 : 1; +} + +static inline void rc32434_start_dma(DMA_Chan_t ch, u32 dma_addr) +{ + local_writel(0, &ch->dmandptr); + local_writel(dma_addr, &ch->dmadptr); +} + +static inline void rc32434_chain_dma(DMA_Chan_t ch, u32 dma_addr) +{ + local_writel(dma_addr, &ch->dmandptr); +} + +#endif // __IDT_DMA_V_H__ + + + + + + + -- cgit v1.2.3
