* dm: core: add function uclass_probe_all() to probe all devicesVabhav Sharma2021-01-161-0/+11
| | | | | | | | | | | | | | | | | | | | 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.

* dtoc: Drop dm_populate_phandle_data()Simon Glass2021-01-051-8/+0
| | | | | | | | | | | | | This has not been needed since parent information was added and we started using indicies for references to other drivers instead of pointers. It was kept around in the expectation that it might be needed later. However with the latest updates, it doesn't seem likely that we'll need this in the foreseeable future. Drop dm_populate_phandle_data() from dtoc and driver model. Signed-off-by: Simon Glass <sjg@chromium.org>
* dtoc: Rename dt-platdata.c to dt-plat.cSimon Glass2021-01-051-1/+1
| | | | | | | Use this new name to be consistent with the rest of U-Boot, which talks about 'plat' for the platform data, which is what this file holds. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Rename U_BOOT_DRIVER_ALIAS to DM_DRIVER_ALIASSimon Glass2021-01-051-1/+1
| | | | | | | | | | | | | We use the U_BOOT_ prefix (i.e. U_BOOT_DRIVER) to declare a driver but in every other case we just use DM_. Update the alias macros to use the DM_ prefix. We could perhaps rename U_BOOT_DRIVER() to DM_DRIVER(), but this macro is widely used and there is at least some benefit to indicating it us a U-Boot driver, particularly for code ported from Linux. So for now, let's keep that name. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Rename DM_GET_DRIVER() to DM_DRIVER_GET()Simon Glass2021-01-052-2/+2
| | | | | | | | 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 <sjg@chromium.org>
* dm: Rename DM_GET_DEVICE() to DM_DRVINFO_GET()Simon Glass2021-01-051-7/+3
| | | | | | | | | | | This does not get a device (struct udevice *) but a struct driver_info * so the name is confusing. Rename it accordingly. Since we plan to have several various of these macros, put GET at the end instead of the middle, so it is easier to spot the related macros. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Rename U_BOOT_DEVICE() to U_BOOT_DRVINFO()Simon Glass2021-01-054-12/+12
| | | | | | | | | | | | | | | | | | | | The current macro is a misnomer since it does not declare a device directly. Instead, it declares driver_info record which U-Boot uses at runtime to create a device. The distinction seems somewhat minor most of the time, but is becomes quite confusing when we actually want to declare a device, with of-platdata. We are left trying to distinguish between a device which isn't actually device, and a device that is (perhaps an 'instance'?) It seems better to rename this macro to describe what it actually is. The macros is not widely used, since boards should use devicetree to declare devices. Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is declaring a new driver_info record, not a device. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: core: Allow the uclass list to moveSimon Glass2021-01-051-0/+1
| | | | | | | | | | | At present the uclass list head is in global_data. This is convenient but with the new of-platdata we need the list head to be declared by the generated code. Change this over to be a pointer. Provide a 'static' version in global_data to retain the current behaviour. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | We have two functions which do the same thing. Standardise on dev_has_ofnode() since there is no such thing as an 'invalid' ofnode in normal operation: it is either null or missing. Also move the functions into one place.

* test: Move some test drivers into their own fileSimon Glass2021-01-051-0/+18
| | | | | | | | | | | 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.

* test: Use a simple variable to record removed deviceSimon Glass2021-01-051-2/+0
| | | | | | | | | | | | At present the entire test state is effective passed into a test driver just to record which device was removed.

* dm: core: Inline a few ofnode functions in SPLSimon Glass2020-12-221-11/+45
| | | | | | | | | | | | | | | | A recent change to unify the flattree/livetree code introduced a small size increase in SPL on some boards. For example SPL code size for px30-core-ctouch2-px30 increased by 40 bytes. To address this we can take advantage of the fact that some of the ofnode functions are only called a few times in SPL, so it is worth inlining them. Add new Kconfig options to control this. These functions are not inlined for U-Boot proper, since this increases code size.

* dm: core: Allow manual sequence numberingSimon Glass2020-12-181-0/+3
| | | | | | | | | | | | | 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 <sjg@chromium.org>
* dm: core: Add a new sequence number for devicesSimon Glass2020-12-181-0/+8
| | | | | | | | | | | | | | | | | | | | | | | At present each device has two sequence numbers, with 'req_seq' being set up at bind time and 'seq' at probe time. The idea is that devices can 'request' a sequence number and then the conflicts are resolved when the device is probed. This makes things complicated in a few cases, since we don't really know what the sequence number will end up being. We want to honour the bind-time requests if at all possible, but in fact the only source of these at present is the devicetree aliases. Since we have the devicetree available at bind time, we may as well just use it, in the hope that the required processing will turn out to be useful later (i.e. the device actually gets used). Add a new 'sqq' member, the bind-time sequence number. It operates in parallel to the old values for now. All devices get a valid sqq value, i.e. it is never -1. Drop an #ifdef while we are here.

* dm: core: Update uclass_find_next_free_req_seq() argsSimon Glass2020-12-181-2/+2
| | | | | | | | | | | At present this is passed a uclass ID and it has to do a lookup. The callers all have the uclass pointer, except for the I2C uclass where the code will soon be deleted.

* dm: Avoid accessing seq directlySimon Glass2020-12-181-0/+5
| | | | | | | | | | At present various drivers etc. access the device's 'seq' member directly. This makes it harder to change the meaning of that member. Change access to go through a function instead. The drivers/i2c/lpc32xx_i2c.c file is left unchanged for now. Signed-off-by: Simon Glass <sjg@chromium.org>

* dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass2020-12-132-19/+19
| | | | | | | | | | | | 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 <sjg@chromium.org>

* board: Rename uclass to sysinfoSimon Glass2020-11-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | This uclass is intended to provide a way to obtain information about a U-Boot board. But the concept of a U-Boot 'board' is the whole system, not just one circuit board, meaning that 'board' is something of a misnomer for this uclass. In addition, the name 'board' is a bit overused in U-Boot and we want to use the same uclass to provide SMBIOS information. The obvious name is 'system' but that is so vague as to be meaningless. Use 'sysinfo' instead, since this uclass is aimed at providing information on the system. Rename everything accordingly. Note: Due to the patch delta caused by the symbol renames, this patch shows some renamed files as being deleted in one place and created in another.
