* dm: core: Allow uclasses to specify platdata for a device's childrenSimon Glass2015-01-29-2/+30
| | | | | | | | | | | | | | 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. If the device provides a size value for its child platdata, then use it. Failng that, fall back to that provided by the uclass.

* dm: core: Allow parents to have platform data for their childrenSimon Glass2015-01-29-0/+81
| | | | | | | | | | | | 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. This can be provided in platform data attached to each child. Add driver model support for this, including auto-allocation which can be requested using a new property to specify the size of the data.

* dm: core: Allocate platform data when binding a deviceSimon Glass2015-01-29-2/+2
| | | | | | | | | | | | When using allocated platform data, allocate it when we bind the device. This makes it possible to fill in this information before the device is probed. This fits with the platform data model (when not using device tree), since platform data exists at bind-time.

* dm: i2c: Provide an offset length parameter where neededSimon Glass2015-01-29-5/+5
| | | | | | | | | | Rather than assuming that the chip offset length is 1, allow it to be provided. This allows chips that don't use the default offset length to be used (at present they are only supported by the command line 'i2c' command which sets the offset length explicitly).

* dm: i2c: Rename driver model I2C functions to permit compatibilitySimon Glass2015-01-29-30/+30
| | | | | | | | | | | Add a dm_ prefix to driver model I2C functions so that we can keep the old ones around. This is a little unfortunate, but on reflection it is too difficult to change the API. We can undo this rename when most boards and drivers are converted to use driver model for I2C. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: gpio: Add better functions to request GPIOsSimon Glass2015-01-29-2/+78
| | | | | | | | | | | | | | | | | | | | | | | At present U-Boot sort-of supports the standard way of reading GPIOs from device tree nodes, but the support is incomplete, a bit clunky and only works for GPIO bindings where #gpio-cells is 2. Add new functions to request GPIOs, taking full account of the device tree binding. These permit requesting a GPIO with a simple call like: gpio_request_by_name(dev, "cd-gpios", 0, &desc, GPIOD_IS_IN); This will request the GPIO, looking at the device's node which might be this, for example: cd-gpios = <&gpio TEGRA_GPIO(B, 3) GPIO_ACTIVE_LOW>; The GPIO will be set to input mode in this case and polarity will be honoured by the GPIO calls. It is also possible to request and free a list of GPIOs. Signed-off-by: Simon Glass <sjg@chromium.org>

* test: Add a simple test to detected warnings with uint64_t, uintptr_tSimon Glass2014-10-27-0/+71
| | | | | | | | | | | | | These types are problematic because they are typically declared in a non-standard way in U-Boot. For example, U-Boot uses 'long long' for int64_t even on a 64-bit machine whereas stdint.h uses 'long'. Similarly, U-Boot always uses 'long' for intptr_t whereas stdint.h mostly uses 'int'. This simple test script runs a few toolchains on a few archs to check for warnings. Signed-off-by: Simon Glass <sjg@chromium.org>
* cli: hush: Adjust 'run' command to run each line of the env varSimon Glass2014-10-27-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | The run command treats each argument an an environment variable. It gets the value of each variable and executes it as a command. If an environment variable contains a newline and the hush cli is used, it is supposed to execute each line one after the other. Normally a newline signals to hush to exit - this is used in normal command line entry - after a command is entered we want to return to allow the user to enter the next one. But environment variables obviously need to execute to completion. Add a special case for the execution of environment variables which continues when a newline is seen, and add a few tests to check this behaviour. Note: it's not impossible that this may cause regressions in other areas. I can't think of a case but with any change of behaviour with limited test coverage there is always a risk. From what I can tell this behaviour has been around since at least U-Boot 2011.03, although this pre-dates sandbox and I have not tested it on real hardware.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Various misc enhancements to dfu_gadget_test.sh: * After every write (download), perform a write to a different file with different data. This ensures that the DFU buffer's content is replaced, so that if the read (upload) succeeds, we know that the correct data was actually read from the storage device, rather than simply being left over in the DFU buffer. This requires two alt setting names to be passed to the script, and a dummy data file to be generated by dfu_gadget_test_init.sh. * Fix the assumption that dfu_gadget_test.sh is run from the directory that contains it, by cd'ing to that directory before invoking ./dfu_gadget_test_init.sh. * Use $DIR$RCV_DIR consistently, rather than using plain $RCV_DIR in some places. * Add 959, 961 test file sizes, to be consistent with having one more than and one less than all the other "round" sizes 64, 128, and 4096. * Remove references to $BKP_DIR from dfu_gadget_test_init.sh, since it isn't used.

* dm: Introduce per-child data for devicesSimon Glass2014-07-23-0/+65
| | | | | | | | | | | | | 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.

* dm: Add functions to access a device's childrenSimon Glass2014-07-23-0/+46
| | | | | | | | | | | | | | | | | 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 <sjg@chromium.org>

* dm: Introduce device sequence numberingSimon Glass2014-07-23-2/+63
| | | | | | | | | | | | | | | | | | | | | | | | | In U-Boot it is pretty common to number devices from 0 and access them on the command line using this numbering. While it may come to pass that we will move away from this numbering, the possibility seems remote at present. Given that devices within a uclass will have an implied numbering, it makes sense to build this into driver model as a core feature. The cost is fairly small in terms of code and data space. With each uclass having numbered devices we can ask for SPI port 0 or serial port 1 and receive a single device. Devices typically request a sequence number using aliases in the device tree. These are resolved when the device is probed, to deal with conflicts. Sequence numbers need not be sequential and holes are permitted. At present there is no support for sequence numbers using static platform data. It could easily be added to 'struct driver_info' if needed, but it seems better to add features as we find a use for them, and the use of -1 to mean 'no sequence' makes the default value somewhat painful.
