From 5eaed880282480a5a0a2b555c5f98a11252ed94e Mon Sep 17 00:00:00 2001 From: Przemyslaw Marczak Date: Wed, 15 Apr 2015 13:07:18 +0200 Subject: dm: core: Extend struct udevice by '.uclass_platdata' field. This commit adds 'uclass_platdata' field to 'struct udevice', which can be automatically allocated at bind. The allocation size is defined in 'struct uclass_driver' as 'per_device_platdata_auto_alloc_size'. New device's flag is added: DM_FLAG_ALLOC_UCLASS_PDATA, which is used for memory freeing at device unbind method. As for other udevice's fields, a complementary function is added: - dev_get_uclass_platdata() Signed-off-by: Przemyslaw Marczak Cc: Simon Glass Acked-by: Simon Glass --- drivers/core/device-remove.c | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'drivers/core/device-remove.c') diff --git a/drivers/core/device-remove.c b/drivers/core/device-remove.c index 7fee1c001e4..6a16b4f690f 100644 --- a/drivers/core/device-remove.c +++ b/drivers/core/device-remove.c @@ -92,6 +92,10 @@ int device_unbind(struct udevice *dev) free(dev->platdata); dev->platdata = NULL; } + if (dev->flags & DM_FLAG_ALLOC_UCLASS_PDATA) { + free(dev->uclass_platdata); + dev->uclass_platdata = NULL; + } if (dev->flags & DM_FLAG_ALLOC_PARENT_PDATA) { free(dev->parent_platdata); dev->parent_platdata = NULL; -- cgit v1.2.3
