dm: Show both allocated and requested seq numbers in 'dm uclass'

Both of these values are useful for understanding what is going on, so show
them both.

The requested number comes from a device tree alias. The allocated one is
set up when the device is activated, and is unique throughout the uclass.

dm: core: Add a uclass pre_probe() method for devices

Some uclasses want to set up a device before it is probed. Add a method
for this.

An example is with PCI, where a PCI uclass wants to set up its private
data for later use. This allows the device's uclass() method to make calls

9 years agodm: core: Mark device as active before calling its probe() method

dm: core: Mark device as active before calling its probe() method

At present the device is not active when the probe() method is called. But
some probe() methods want to set up the device and this can involve
accessing it through normal methods. For example a PCI bus may wish to
set up its PCI parameters using calls to pci_hose_write_config_dword() and
similar.

At present this does not work because every such call within the probe()
method sees that the device is not active and attempts to probe it.

Already we mark the device as probed before calling the uclass post_probe()
method. This is a subtle change but I believe the new approach is better.
Since the scope of the change is only the probe() method and all its callees
it should still be within the control of the board author.

sunxi: usbc: Wait for vbus to fall after disabling it

When u-boot boots the board may be powering vbus, we turn off vbus in
sunxi_usbc_request_resources, if we are too quick with reading vusb-detect
after this we may see a residual charge and assume we've an external vusb
connected even though we do not. So when we see an external vusb wait a bit
and try again.

Without this when dealing with a pmic controller vbus and doing "reset" on
the u-boot console the musb host will only init once every other boot, because
the other boot it thinks an external vbus is present, this commit fixes this.

On boards which use the pmic to enable/disable vbus on the otg port, the
vbus value is not reset to 0 on reset, as reset only resets the SoC and not
