* dm: core: Allow uclass to set up a device's child before it is probedSimon Glass2015-01-29-0/+3
| | | | | | | | | 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. Support a common pre-probe method for the uclass, called before any bus devices are probed. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* test: dm: Support memory leak checking as a core featureSimon Glass2014-10-23-0/+23
| | | | | | | | Check the state of the malloc() heap before each test is run, so that tests can verify that all is well at the end. Provide helper functions to mark the heap and to check that it returns to its initial state. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Add child_pre_probe() and child_post_remove() methodsSimon Glass2014-07-23-0/+4
| | | | | | | | | | | Some devices (particularly bus devices) must track their children, knowing when a new child is added so that it can be set up for communication on the bus. Add a child_pre_probe() method to provide this feature, and a corresponding child_post_remove() method. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Introduce per-child data for devicesSimon Glass2014-07-23-0/+9
| | | | | | | | | | | | | 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 <sjg@chromium.org>
* dm: Provide a function to scan child FDT nodesSimon Glass2014-07-23-0/+9
| | | | | | | | | | | | | | 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 <sjg@chromium.org>
* dm: rename device struct to udeviceHeiko Schocher2014-05-27-6/+6
| | | | | | | | | | | | using UBI and DM together leads in compiler error, as both define a "struct device", so rename "struct device" in include/dm/device.h to "struct udevice", as we use linux code (MTD/UBI/UBIFS some USB code,...) and cannot change the linux "struct device" Signed-off-by: Heiko Schocher <hs@denx.de> Cc: Simon Glass <sjg@chromium.org> Cc: Marek Vasut <marex@denx.de>
* dm: Add basic testsSimon Glass2014-03-04-0/+167
Add some tests of driver model functionality. Coverage includes: - basic init - binding of drivers to devices using platform_data - automatic probing of devices when referenced - availability of platform data to devices - lifecycle from bind to probe to remove to unbind - renumbering within a uclass when devices are probed/removed - calling driver-defined operations - deactivation of drivers when removed - memory leak across creation and destruction of drivers/uclasses - uclass init/destroy methods - automatic probe/remove of children/parents when needed This function is enabled for sandbox, using CONFIG_DM_TEST.
