dm: Use an allocated array for run-time device info

2020-10-29T20:42:18Z

At present we update the driver_info struct with a pointer to the device that it created (i.e. caused to be bound). This works fine when U-Boot SPL is stored in read-write memory. But on some platforms, such as Intel Apollo Lake, it is not possible to update the data memory. In any case, it is bad form to put this information in a structure that is in the data region, since it expands the size of the binary. Create a new driver_rt structure which holds runtime information about drivers. Update the code to store the device pointer in this instead. Also update the test check that this works.

dm: core: add support for device re-parenting

2020-09-22T08:27:18Z

In common clock framework the relation b/w parent and child clocks is determined based on the udevice parent/child information. A clock parent could be changed based on devices needs. In case this is happen the functionalities for clock who's parent is changed are broken. Add a function that reparent a device. This will be used in clk-uclass.c to reparent a clock device.

core: drop const for struct driver_info

2020-07-10T04:00:29Z

In order to prepare for a new support of phandle when OF_PLATDATA is used drop the const for struct driver_info as this struct will need to be updated on runtime. Signed-off-by: Walter Lozano Reviewed-by: Simon Glass

dm: core: Export a new function to read platdata

2020-01-07T23:02:38Z

Add a new internal function, device_ofdata_to_platdata() to handle allocating private space associated with each device and reading the platform data from the device tree. Call this new function from device_probe(). Signed-off-by: Simon Glass

dm: Correct pre_reloc_only parameter description in several APIs' comments

2018-11-14T17:16:27Z

The pre_reloc_only parameter description currently only mentions drivers with the DM_FLAG_PRE_RELOC flag, but does not mention the special device tree properties. Correct them. Signed-off-by: Bin Meng Reviewed-by: Simon Glass

device: expose the functions used to remove and unbind children of a device

2018-08-21T14:21:37Z

Also add a 'drv' parameter to filter the children to remove/unbind. Exporting those functions is a preparatory work for the addition of the bind/unbind commands. Signed-off-by: Jean-Jacques Hiblot

dm: core: Add a way to bind a device by ofnode

2018-07-09T15:11:00Z

Add a new device_bind_ofnode() function which can bind a device given its ofnode. This allows binding devices more easily with livetree nodes. Signed-off-by: Simon Glass

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

dm: core: Add a comment about the device_remove() flags

2017-08-17T07:44:16Z

We should explain which flags are used for this function. Update the comment to indicate this. Signed-off-by: Simon Glass

dm: core: Allow binding a device from a live tree

2017-06-01T13:03:08Z

When a live tree is being used we need to record the node that was used to create the device. Update device_bind_with_driver_data() to support this. Signed-off-by: Simon Glass
