From 85bcc13072c54592596c5b41d40d1c6a18b04e19 Mon Sep 17 00:00:00 2001 From: Pierre Ossman Date: Sun, 8 May 2005 19:35:27 +0100 Subject: [PATCH] MMC: wbsd update Updates to the wbsd driver. * Fix to handle DAT3 card detection. * Fixed bug which could cause large writes to stall in FIFO mode. * Plug 'n Play support. In most cases you need ACPI PNP for this to work. * Uses generic DMA API (ISA dependency removed). --- drivers/mmc/wbsd.h | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'drivers/mmc/wbsd.h') diff --git a/drivers/mmc/wbsd.h b/drivers/mmc/wbsd.h index fdc03b56a81f..864f30828d01 100644 --- a/drivers/mmc/wbsd.h +++ b/drivers/mmc/wbsd.h @@ -35,6 +35,12 @@ const int valid_ids[] = { #define DEVICE_SD 0x03 +#define WBSD_PINS_DAT3_HI 0x20 +#define WBSD_PINS_DAT3_OUT 0x10 +#define WBSD_PINS_GP11_HI 0x04 +#define WBSD_PINS_DETECT_GP11 0x02 +#define WBSD_PINS_DETECT_DAT3 0x01 + #define WBSD_CMDR 0x00 #define WBSD_DFR 0x01 #define WBSD_EIR 0x02 @@ -133,6 +139,7 @@ const int valid_ids[] = { #define WBSD_CRC_OK 0x05 /* S010E (00101) */ #define WBSD_CRC_FAIL 0x0B /* S101E (01011) */ +#define WBSD_DMA_SIZE 65536 struct wbsd_host { @@ -140,6 +147,11 @@ struct wbsd_host spinlock_t lock; /* Mutex */ + int flags; /* Driver states */ + +#define WBSD_FCARD_PRESENT (1<<0) /* Card is present */ +#define WBSD_FIGNORE_DETECT (1<<1) /* Ignore card detection */ + struct mmc_request* mrq; /* Current request */ u8 isr; /* Accumulated ISR */ -- cgit v1.2.3
