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

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 clocks node scan

2017-09-12T03:43:58Z

Currently, all fixed-clock declared in "clocks" node in device tree can be binded by clk_fixed_rate.c driver only if each of them have the "simple-bus" compatible string. This constraint has been invoked here [1]. This patch offers a solution to avoid adding "simple-bus" compatible string to nodes that are not busses.

dm: core: Scan the live tree when setting up driver model

2017-06-01T13:03:08Z

When starting up driver model with a live tree we need to scan the tree for devices. Add code to handle this. Signed-off-by: Simon Glass

dm: core: Dont export dm_scan_fdt_node()

2017-06-01T13:03:03Z

This function is only used in one place. It is better to just declare it internally since there is a simpler replacement for use outside the driver-model core code. Signed-off-by: Simon Glass

dm: core: Add dm_remove_devices_flags() and hook it into device_remove()

2017-04-05T02:15:10Z

The new function dm_remove_devices_flags() is intented for driver specific last-stage cleanup operations before the OS is started. This patch adds this functionality and hooks it into the common device_remove() function. Drivers wanting to use this feature for some last-stage removal calls, need to add one of the DM_REMOVE_xx flags to their driver .flags. Signed-off-by: Stefan Roese Reviewed-by: Simon Glass

dm: core: Handle global_data moving in SPL

2016-12-03T03:53:19Z

When CONFIG_SPL_STACK_R is enabled, and spl_init() is called before board_init_r(), spl_relocate_stack_gd() will move global_data to a new place in memory. This affects driver model since it uses a list for the uclasses. Unless this is updated the list will become invalid. When looking for a non-existent uclass, such as when adding a new one, the loop in uclass_find() may continue forever, thus causing a hang. Add a function to correct this rather obscure bug.

dm: Add dm_scan_other() to locate board-specific devices

2014-07-23T13:08:37Z

Some boards will have devices which are not in the device tree and do not have platform data. They may be programnatically created, for example. Add a hook which boards can use to bind those devices early in boot. Signed-off-by: Simon Glass

dm: Provide a function to scan child FDT nodes

2014-07-23T13:08:36Z

At present only root nodes in the device tree are scanned for devices. But some devices can have children. For example a SPI bus may have several children for each of its chip selects. Add a function which scans subnodes and binds devices for each one. This can be used for the root node scan also, so change it. A device can call this function in its bind() or probe() methods to bind its children. Signed-off-by: Simon Glass
