From 1bdae6f49c52af3a58998cdb051dbd5b942f9273 Mon Sep 17 00:00:00 2001 From: Narayanan G Date: Thu, 9 Feb 2012 12:41:37 +0530 Subject: dma40: Improve the logic of stopping logical chan can be directly stopped by issuing a SUSPEND_REQ on the EE bits. There is no need to suspend the physical channel and restart it. Also, the support for pre-V2 hw is discontinued. EE bits for writing: 00: disable only if AS=11 or AS=00 01: enable 10: suspend_req only if AS=01 & EE=01 or EE=11 11: round / no change for writing Signed-off-by: Narayanan G Acked-by: Linus Walleij Signed-off-by: Vinod Koul --- drivers/dma/ste_dma40_ll.h | 2 -- 1 file changed, 2 deletions(-) (limited to 'drivers/dma/ste_dma40_ll.h') diff --git a/drivers/dma/ste_dma40_ll.h b/drivers/dma/ste_dma40_ll.h index 8d3d490968a3..51e8e5396e9b 100644 --- a/drivers/dma/ste_dma40_ll.h +++ b/drivers/dma/ste_dma40_ll.h @@ -62,8 +62,6 @@ #define D40_SREG_ELEM_LOG_LIDX_MASK (0xFF << D40_SREG_ELEM_LOG_LIDX_POS) /* Link register */ -#define D40_DEACTIVATE_EVENTLINE 0x0 -#define D40_ACTIVATE_EVENTLINE 0x1 #define D40_EVENTLINE_POS(i) (2 * i) #define D40_EVENTLINE_MASK(i) (0x3 << D40_EVENTLINE_POS(i)) -- cgit v1.2.3
