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 --- include/dm/uclass.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'include/dm/uclass.h') diff --git a/include/dm/uclass.h b/include/dm/uclass.h index d57d804..b271472 100644 --- a/include/dm/uclass.h +++ b/include/dm/uclass.h @@ -65,6 +65,9 @@ struct udevice; * @per_device_auto_alloc_size: Each device can hold private data owned * by the uclass.
