pci: sandbox: Move the emulators into their own node
Sandbox pci works using emulation drivers which are currently children of
the pci device:
pci-controller {
pci@1f,0 {
compatible = "pci-generic";
reg = <0xf800 0 0 0 0>;
emul@1f,0 {
compatible = "sandbox,swap-case";
};
};
};
In this case the emulation device is attached to pci device on address
f800 (device 1f, function 0) and provides the swap-case functionality.
However this is not ideal, since every device on a PCI bus has a child
device. This is only really the case for sandbox, but we want to avoid
special-case code for sandbox.
Worse, child devices cannot be probed before their parents. This forces
us to use 'find' rather than 'get' to obtain the emulator device. In fact
the emulator devices are never probed. There is code in
sandbox_pci_emul_post_probe() which tries to track when emulators are
active, but at present this does not work.
A better approach seems to be to add a separate node elsewhere in the
device tree, an 'emulation parent'. This could be given a bogus address
(such as -1) to hide the emulators away from the 'pci' command, but it
seems better to keep it at the root node to avoid such hacks.
Then we can use a phandle to point from the device to the correct
emulator, and only on sandbox. The code to find an emulator does not
interfere with normal pci operation.
Add a new UCLASS_PCI_EMUL_PARENT uclass which allows finding an emulator
given a bus, and finding a bus given an emulator. Update the existing
device trees and the code for finding an emulator.
This brings PCI emulators more into line with I2C.
