dm: core: add function uclass_probe_all() to probe all devices

2021-01-16T19:49:09Z

Support a common method to probe all devices associated with uclass. This includes data structures and code for finding the first device and looping for remaining devices associated with uclasses (groups of devices with the same purpose, e.g. all SERIAL ports will be in the same uclass). An example is SBSA compliant PL011 UART IP, where firmware does the serial port initialization and prepare uart device to let the kernel use it for sending and reveiving the characters.SERIAL uclass will use this function to initialize PL011 UART ports. The feature is enabled with CONFIG_DM. Signed-off-by: Vabhav Sharma Reviewed-by: Stefan Roese Reviewed-by: Simon Glass Reviewed-by: Sean Anderson

dm: Rename DM_GET_DRIVER() to DM_DRIVER_GET()

2021-01-05T19:26:35Z

In the spirit of using the same base name for all of these related macros, rename this to have the operation at the end. This is not widely used so the impact is fairly small. Signed-off-by: Simon Glass

dm: core: Rename the priv/plat members

2021-01-05T19:24:40Z

These are supposed to be private to driver model, not accessed by any code outside. Add a trailing underscore to indicate this. Signed-off-by: Simon Glass

dm: core: Add function to access uclass priv

2021-01-05T19:24:40Z

Add functions so this information is not accessed directly. This will be needed for of-platdata which stores it in a different place. Signed-off-by: Simon Glass

dm: core: Use 'uclass_driver' for the uclass linker_list

2021-01-05T19:24:40Z

At present the name 'uclass_driver' is used for the uclass linker list. This does not follow the convention of using the struct name. Fix it. Signed-off-by: Simon Glass

dm: Drop uclass_resolve_seq()

2020-12-19T03:32:21Z

This function is not needed anymore. Drop it. Signed-off-by: Simon Glass

dm: core: Allow manual sequence numbering

2020-12-19T03:32:21Z

Some buses have their own rules which require assigning sequence numbers with a bus-specific algorithm. For example, PCI requires that sub-buses are numbered higher than their parent buses, meaning effectively that parent buses must be numbered only after all of their child buses have been numbered. Add a uclass flag to indicate that driver model should not assign sequence numbers. In this case, the uclass must do it. Signed-off-by: Simon Glass

dm: treewide: Rename 'platdata' variables to just 'plat'

2020-12-13T23:51:08Z

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

dm: treewide: Rename auto_alloc_size members to be shorter

2020-12-13T15:00:25Z

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
