* [PATCH v7] ata/pata_buddha: Probe via modalias instead of initcall @ 2019-08-23 10:49 ` Max Staudt 2019-08-23 11:18 ` Bartlomiej Zolnierkiewicz 2019-08-23 12:59 ` Jens Axboe 0 siblings, 2 replies; 4+ messages in thread From: Max Staudt @ 2019-08-23 10:49 UTC (permalink / raw) To: b.zolnierkie, axboe Cc: linux-ide, linux-m68k, linux-kernel, glaubitz, schmitzmic, geert, Max Staudt Up until now, the pata_buddha driver would only check for cards on initcall time. Now, the kernel will call its probe function as soon as a compatible card is detected. v7: Removed suppress_bind_attrs that slipped in v6: Only do the drvdata workaround for X-Surf (remove breaks otherwise) Style v5: Remove module_exit(): There's no good way to handle the X-Surf hack. Also include a workaround to save X-Surf's drvdata in case zorro8390 is active. v4: Clean up pata_buddha_probe() by using ent->driver_data. Support X-Surf via late_initcall() v3: Clean up devm_*, implement device removal. v2: Rename 'zdev' to 'z' to make the patch easy to analyse with git diff --ignore-space-change Signed-off-by: Max Staudt <max@enpas.org> --- drivers/ata/pata_buddha.c | 228 +++++++++++++++++++++++++++------------------- 1 file changed, 135 insertions(+), 93 deletions(-) diff --git a/drivers/ata/pata_buddha.c b/drivers/ata/pata_buddha.c index 11a8044ff..27d4c417f 100644 --- a/drivers/ata/pata_buddha.c +++ b/drivers/ata/pata_buddha.c @@ -18,7 +18,9 @@ #include <linux/kernel.h> #include <linux/libata.h> #include <linux/mm.h> +#include <linux/mod_devicetable.h> #include <linux/module.h> +#include <linux/types.h> #include <linux/zorro.h> #include <scsi/scsi_cmnd.h> #include <scsi/scsi_host.h> @@ -29,7 +31,7 @@ #include <asm/setup.h> #define DRV_NAME "pata_buddha" -#define DRV_VERSION "0.1.0" +#define DRV_VERSION "0.1.1" #define BUDDHA_BASE1 0x800 #define BUDDHA_BASE2 0xa00 @@ -47,11 +49,11 @@ enum { BOARD_XSURF }; -static unsigned int buddha_bases[3] __initdata = { +static unsigned int buddha_bases[3] = { BUDDHA_BASE1, BUDDHA_BASE2, BUDDHA_BASE3 }; -static unsigned int xsurf_bases[2] __initdata = { +static unsigned int xsurf_bases[2] = { XSURF_BASE1, XSURF_BASE2 }; @@ -145,111 +147,151 @@ static struct ata_port_operations pata_xsurf_ops = { .set_mode = pata_buddha_set_mode, }; -static int __init pata_buddha_init_one(void) +static int pata_buddha_probe(struct zorro_dev *z, + const struct zorro_device_id *ent) { - struct zorro_dev *z = NULL; + static const char * const board_name[] = { + "Buddha", "Catweasel", "X-Surf" + }; + struct ata_host *host; + void __iomem *buddha_board; + unsigned long board; + unsigned int type = ent->driver_data; + unsigned int nr_ports = (type == BOARD_CATWEASEL) ?
