The RB532 platform specific irq_to_gpio() implementation has been removed with commit 832f5dacfa0b ("MIPS: Remove all the uses of custom gpio.h"). Now the platform uses the generic stub which causes the following error: pata-rb532-cf pata-rb532-cf: no GPIO found for irq149 pata-rb532-cf: probe of pata-rb532-cf failed with error -2 Drop the irq_to_gpio() call and get the GPIO number from platform data instead. After this change, the driver works again: scsi host0: pata-rb532-cf ata1: PATA max PIO4 irq 149 ata1.00: CFA: CF 1GB, 20080820, max MWDMA4 ata1.00: 1989792 sectors, multi 0: LBA ata1.00: configured for PIO4 scsi 0:0:0:0: Direct-Access ATA CF 1GB 0820 PQ: 0\ ANSI: 5 sd 0:0:0:0: [sda] 1989792 512-byte logical blocks: (1.01 GB/971 MiB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Write cache: disabled, read cache: enabled, doesn't\ support DPO or FUA sda: sda1 sda2 sd 0:0:0:0: [sda] Attached SCSI disk Fixes: 832f5dacfa0b ("MIPS: Remove all the uses of custom gpio.h") Cc: Alban Bedel <albeu@xxxxxxx> Cc: Ralf Baechle <ralf@xxxxxxxxxxxxxx> Cc: Arnd Bergmann <arnd@xxxxxxxx> Cc: <stable@xxxxxxxxxxxxxxx> Signed-off-by: Gabor Juhos <juhosg@xxxxxxxxxxx> --- drivers/ata/pata_rb532_cf.c | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) diff --git a/drivers/ata/pata_rb532_cf.c b/drivers/ata/pata_rb532_cf.c index 12fe0f3..c8b6a78 100644 --- a/drivers/ata/pata_rb532_cf.c +++ b/drivers/ata/pata_rb532_cf.c @@ -32,6 +32,8 @@ #include <linux/libata.h> #include <scsi/scsi_host.h> +#include <asm/mach-rc32434/rb.h> + #define DRV_NAME "pata-rb532-cf" #define DRV_VERSION "0.1.0" #define DRV_DESC "PATA driver for RouterBOARD 532 Compact Flash" @@ -107,6 +109,7 @@ static int rb532_pata_driver_probe(struct platform_device *pdev) int gpio; struct resource *res; struct ata_host *ah; + struct cf_device *pdata; struct rb532_cf_info *info; int ret; @@ -122,7 +125,13 @@ static int rb532_pata_driver_probe(struct platform_device *pdev) return -ENOENT; } - gpio = irq_to_gpio(irq); + pdata = dev_get_platdata(&pdev->dev); + if (!pdata) { + dev_err(&pdev->dev, "no platform data specified\n"); + return -EINVAL; + } + + gpio = pdata->gpio_pin; if (gpio < 0) { dev_err(&pdev->dev, "no GPIO found for irq%d\n", irq); return -ENOENT; -- 1.7.10 -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
