2024-08-26test: Rename unit-test flagsSimon Glass
The UT_TESTF_ macros read as 'unit test test flags' which is not right. Rename to UTF ('unit test flags'). This has the benefit of being shorter, which helps keep UNIT_TEST() declarations on a single line. Give the enum a name and reference it from the UNIT_TEST() macros while we are here.

2024-07-31dm: use list_count_nodes() for counting list nodesSughosh Ganu
The linux kernel has the list_count_nodes() API functions which is used for counting nodes of a list. This has now been imported in U-Boot as part of an earlier commit. Use this function and drop the list_count_items().

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

2021-02-02common: Drop asm/global_data.h from common headerSimon Glass
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2021-01-05dm: core: Access device flags through functionsSimon Glass
At present flags are stored as part of the device. In preparation for storing them separately, change the access to go through inline functions. Signed-off-by: Simon Glass <[email protected]>
2021-01-05test: Move some test drivers into their own fileSimon Glass
At present several test drivers are part of the test file itself. Some of these are useful for of-platdata tests. Separate them out so we can use them for other things also. A few adjustments are needed so this driver can build for sandbox_spl as well. Signed-off-by: Simon Glass <[email protected]>
2021-01-05test: Use a simple variable to record removed deviceSimon Glass
At present the entire test state is effective passed into a test driver just to record which device was removed. This is unnecessary and makes it harder to track what is going on. Use a simple boolean instead. Also drop the unused 'removed' member while we are here. Signed-off-by: Simon Glass <[email protected]>
2020-12-18dm: Drop the unused arg in uclass_find_device_by_seq()Simon Glass

2020-12-13dm: treewide: Update 'auto' declarations to be on one lineSimon Glass
Fix up the code style for those declarations that should now fit onto one line, which is all of them that currently do not. This is needed for dtoc to detect the structs correctly, at present. Signed-off-by: Simon Glass <[email protected]>
2020-12-13dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <[email protected]>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <[email protected]>

2020-08-07dm: Rename DM test flags to make them more genericSimon Glass
The test flags used by driver model are currently not available to other tests. Rather than creating two sets of flags, make these flags generic by changing the DM_ prefix to UT_ and moving them to the test.h header. This will allow adding other test flags without confusion.

2020-08-03dm: core: Drop header files from dm/test.hSimon Glass

2018-10-08sandbox: Unprotect DATA regions in bus testsSimon Glass
On my Ubuntu 18.04.1 machine two driver-model bus tests have started failing recently. The problem appears to be that the DATA region of the executable is protected. This does not seem correct, but perhaps there is a reason. To work around it, unprotect the regions in these tests before accessing them. Signed-off-by: Simon Glass <[email protected]>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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 <[email protected]>

2015-01-29dm: core: Allow uclass to set up a device's child before it is probedSimon Glass
Some buses need to set up their devices before they can be used. This setup may well be common to all buses in a particular uclass.

2015-01-29dm: core: Allow the uclass to set up a device's child after bindingSimon Glass
For buses, after a child is bound, allow the uclass to perform some processing. This can be used to figure out the address of the child (e.g. the chip select for SPI slaves) so that it is ready to be probed. This avoids bus drivers having to repeat the same process, which really should be done by the uclass, since it is common.

2015-01-29dm: core: Allow uclasses to specify private data for a device's childrenSimon Glass
In many cases the per-child private data for a device's children is defined by the uclass rather than the individual driver. For example, a SPI bus needs to store information about each of its children, but all SPI drivers store the same information. It makes sense to allow the uclass to define this data. If the driver provides a size value for its per-child private data, then use it. Failng that, fall back to that provided by the uclass.

2015-01-29dm: core: Add a flag to control sequence numberingSimon Glass
At present we try to use the 'reg' property and device tree aliases to give devices a sequence number. The 'reg' property is often actually a memory address, so the sequence numbers thus-obtained are not useful. It would be better if the devices were just sequentially numbered in that case. In fact neither I2C nor SPI use this feature, so drop it. Some devices need us to look up an alias to number them within the uclass. Add a flag to control this, so it is not done unless it is needed.

In many cases the child platform data for a device's children is defined by the uclass rather than the individual devices. For example, a SPI bus needs to know the chip select and speed for each of its children. It makes sense to allow this information to be defined the SPI uclass rather than each individual driver.

2015-01-29dm: core: Allow parents to have platform data for their childrenSimon Glass
For buses it is common for parents to need to know the address of the child on the bus, the bus speed to use for that child, and other information.

2014-07-23dm: Add child_pre_probe() and child_post_remove() methodsSimon Glass

2014-07-23dm: Introduce per-child data for devicesSimon Glass
Some device types can have child devices and want to store information about them. For example a USB flash stick attached to a USB host controller would likely use this space. The controller can hold information about the USB state of each of its children. The data is stored attached to the child device in the 'parent_priv' member. It can be auto-allocated by dm when the child is probed. To do this, add a per_child_auto_alloc_size value to the parent driver. Signed-off-by: Simon Glass <[email protected]>
2014-07-23dm: Add functions to access a device's childrenSimon Glass
Devices can have childen that can be addressed by a simple index, the sequence number or a device tree offset. Add functions to access a child in each of these ways. The index is typically used as a fallback when the sequence number is not available. For example we may use a serial UART with sequence number 0 as the console, but if no UART has sequence number 0, then we can fall back to just using the first UART (index 0). The device tree offset function is useful for buses, where they want to locate one of their children. The device tree can be scanned to find the offset of each child, and that offset can then find the device. Signed-off-by: Simon Glass <[email protected]>
2014-07-23dm: Provide a function to scan child FDT nodesSimon Glass
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 <[email protected]>
