| * dm: core: Add a way to set a device nameSimon Glass2015-08-06-0/+15
| | | | | | | | | | | | | | | | | | | | Some devices are bound entirely by probing and do not have the benefit of a device tree to give them a name. This is very common with PCI and USB. In most cases this is fine, but we should add an official way to set a device name. This should be called in the device's bind() method.

| * devres: add debug command to dump device resourcesMasahiro Yamada2015-08-06-0/+9

The fields in every line shows: - The address of the resource - The size of the resource - The name of the release function - The stage in which the resource has been acquired (BIND/PROBE) Currently, there is no driver using devres, but if such drivers are implemented, the output of this command should look like this: => dm devres - root_driver - soc - extbus - serial@54006800 bfb541e8 (8 byte) devm_kmalloc_release BIND bfb54440 (4 byte) devm_kmalloc_release PROBE bfb54460 (4 byte) devm_kmalloc_release PROBE - serial@54006900 bfb54270 (8 byte) devm_kmalloc_release BIND - gpio@55000000 - i2c@58780000 bfb5bce8 (12 byte) devm_kmalloc_release PROBE bfb5bd10 (4 byte) devm_kmalloc_release PROBE - eeprom bfb54418 (12 byte) devm_kmalloc_release BIND Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Simon Glass <sjg@chromium.org>
| * devres: make Devres optional with CONFIG_DEVRESMasahiro Yamada2015-08-06-0/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, Devres requires additional 16 byte for each allocation, which is not so insignificant in some cases. Add CONFIG_DEVRES to make this framework optional. If the option is disabled, devres functions fall back to non-managed variants. For example, devres_alloc() to kzalloc(), devm_kmalloc() to kmalloc(), etc. Because devres_head is also surrounded by an ifdef conditional, there is no memory overhead when CONFIG_DEVRES is disabled.

| * devres: introduce Devres (Managed Device Resource) frameworkMasahiro Yamada2015-08-06-0/+159
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In U-Boot's driver model, memory is basically allocated and freed in the core framework. So, low level drivers generally only have to specify the size of needed memory with .priv_auto_alloc_size, .platdata_auto_alloc_size, etc. Nevertheless, some drivers still need to allocate/free memory on their own in case they cannot statically know the necessary memory size. So, I believe it is reasonable enough to port Devres into U-boot. Devres, which originates in Linux, manages device resources for each device and automatically releases them on driver detach. With devres, device resources are guaranteed to be freed whether initialization fails half-way or the device gets detached. The basic idea is totally the same to that of Linux, but I tweaked it a bit so that it fits in U-Boot's driver model. In U-Boot, drivers are activated in two steps: binding and probing. Binding puts a driver and a device together. It is just data manipulation on the system memory, so nothing has happened on the hardware device at this moment. When the device is really used, it is probed. Probing initializes the real hardware device to make it really ready for use. So, the resources acquired during the probing process must be freed when the device is removed. Likewise, what has been allocated in binding should be released when the device is unbound. The struct devres has a member "probe" to remember when the resource was allocated. CONFIG_DEBUG_DEVRES is also supported for easier debugging. If enabled, debug messages are printed each time a resource is allocated/freed. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Simon Glass <sjg@chromium.org>

| * cros_ec: Support the LDO access method used by springSimon Glass2015-08-05-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a driver to support the special LDO access used by spring. This is a custom method in the cros_ec protocol - it does not use an I2C pass-through. There are two implementation choices: 1. Write a special LDO driver which can talk across the EC. Duplicate all the logic from TPS65090 for retrying when the LDO fails to come up. 2. Write a special I2C bus driver which pretends to be a TPS65090 and transfers reads and writes using the LDO message. Either is distasteful. The latter method is chosen since it results in less code duplication and a fairly simple (30-line) implementation of the core logic. The crosec 'ldo' subcommand could be removed (since i2c md/mw will work instead) but is retained as a convenience. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: cros_ec: Convert the I2C tunnel code to use driver modelSimon Glass2015-08-05-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Chrome OS EC supports tunnelling through to an I2C bus on the EC. This currently uses a copy of the I2C command code and a special 'crosec' sub-command. With driver model we can define an I2C bus which tunnels through to the EC, and use the normal 'i2c' command to access it. This simplifies the code and removes some duplication. Add an I2C driver which tunnels through to the EC. Adjust the EC code to support binding child devices so that it can be set up. Adjust the existing I2C xfer function to fit driver model better. For now the old code remains to allow things to still work. It will be removed in a later patch once the new flow is fully enabled. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: i2c: Add support for multiplexed I2C busesSimon Glass2015-08-05-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new I2C_MUX uclass. Devices in this class can multiplex between several I2C buses, selecting them one at a time for use by the system. The multiplexing mechanism is left to the driver to decide - it may be controlled by GPIOs, for example. The uclass supports only two methods: select() and deselect(). The current mux state is expected to be stored in the mux itself since it is the only thing that knows how to make things work. The mux can record the current state and then avoid switching unless it is necessary. So select() can be skipped if the mux is already in the correct state. Also deselect() can be made a nop if required. Signed-off-by: Simon Glass <sjg@chromium.org>
