From 37c12e7497b6fe2b6a890814f0ff4edce696d862 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 5 Nov 2005 21:19:33 +0000 Subject: [DRIVER MODEL] Improved dynamically allocated platform_device interface Re-jig the simple platform device support to allow private data to be attached to a platform device, as well as allowing the parent device to be set. Example usage: pdev = platform_device_alloc("mydev", id); if (pdev) { err = platform_device_add_resources(pdev, &resources, ARRAY_SIZE(resources)); if (err == 0) err = platform_device_add_data(pdev, &platform_data, sizeof(platform_data)); if (err == 0) err = platform_device_add(pdev); } else { err = -ENOMEM; } if (err) platform_device_put(pdev); Signed-off-by: Russell King Acked-by: Greg Kroah-Hartman --- include/linux/platform_device.h | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'include/linux/platform_device.h') diff --git a/include/linux/platform_device.h b/include/linux/platform_device.h index a726225e0af..1a165b7ae01 100644 --- a/include/linux/platform_device.h +++ b/include/linux/platform_device.h @@ -37,4 +37,10 @@ extern int platform_add_devices(struct platform_device **, int); extern struct platform_device *platform_device_register_simple(char *, unsigned int, struct resource *, unsigned int); +extern struct platform_device *platform_device_alloc(const char *name, unsigned int id); +extern int platform_device_add_resources(struct platform_device *pdev, struct resource *res, unsigned int num); +extern int platform_device_add_data(struct platform_device *pdev, void *data, size_t size); +extern int platform_device_add(struct platform_device *pdev); +extern void platform_device_put(struct platform_device *pdev); + #endif /* _PLATFORM_DEVICE_H_ */ -- cgit v1.2.3
