When CONFIG_OF_LIVE is enabled, dev_of_offset() cannot be used and
|
||||
if used returns an invalid offset. This causes the call to
|
||||
fdt_stringlist_get() in the psci_probe() to fail to read the 'method'
|
||||
property from the PSCI node for the device and hence prevents PSCI
|
||||
from working. Fix this by using the ofnode_read_string() API instead
|
||||
of the fdt_stringlist_get() because this will handle reading the
|
||||
property both when CONFIG_OF_LIVE is enabled or disabled.
|
||||
|
||||
Due to the above problem and since commit 81ea00838c68 ("efi_loader:
|
||||
PSCI reset and shutdown") was added, the EFI system reset has been
|
||||
broken for Tegra210 and Tegra196 platforms. This also fixes the EFI
|
||||
system reset for these Tegra platforms.

|

The PSCI nodes are currently not populated for the Tegra210 and Tegra186
|
||||
devices. This prevents the PSCI driver from being able to identify the
|
||||
PSCI method used by these devices and causes the probe of the PSCI
|
||||
driver to fail.
|
||||
|
||||
Since commit 81ea00838c68 ("efi_loader: PSCI reset and shutdown") was
|
||||
added, which moves the PSCI EFI system reset handler into the PSCI
|
||||
driver, this has prevented the EFI system reset from working for
|
||||
Tegra210 and Tegra186. Therefore, populating these nodes is necessary
|
||||
to fix the EFI system reset for Tegra210 and Tegra186.

When needed, RPi4's co-processor (called VideoCore) has to be instructed
|
||||
to load VL805's firmware (the chip providing xHCI support). VideCore's
|
||||
firmware expects the board's PCIe bus to be already configured in order
|
||||
for it to load the xHCI chip firmware. So we have to make sure this
|
||||
happens in between the PCIe configuration and xHCI startup.
|
||||
|
||||
Introduce a callback in xhci_pci_probe() to run this platform specific
|
||||
routine.
|
||||
Raspberry Pi 4's co-processor controls some of the board's HW
|
||||
initialization process, but it's up to Linux to trigger it when
|
||||
relevant. Introduce a reset controller capable of interfacing with
|
||||
RPi4's co-processor that models these firmware initialization routines as
|
||||
reset lines.

There is no distinction in DT between the PCI controller device and the
|
||||
root bridge, whereas such distinction exists from dm's perspective. Make
|
||||
sure the root bridge ofnode is assigned to the controller's platform
|
||||
device node.
|
||||
|
||||
This permits setups like this to work correctly:
|
||||
|
||||
pcie {
|
||||
compatible = "...";
|
||||
...
|
||||
dev {
|
||||
reg = <0 0 0 0 0>;
|
||||
...
|
||||
};
|
||||
};
|
||||
|
||||
Without this the dev node is assigned to the root bridge and the
|
||||
actual device search starts one level lower than expected.

Some atypical users of xhci-pci might need to manually reset their xHCI
|
||||
controller before starting the HCD setup. Check if a reset controller
|
||||
device is available to the PCI bus and trigger a reset.
