The previously provided device path made no difference, all
integrated PCI devices point back to the same chip_info
structure.
Change reduces the exposure of various SA_DEVFN_xx and
PCH_DEVFN_xx from (ugly) soc/pci_devs.h.

dev_find_slot() can sometimes fail to return the desired device object
prior to full PCI enumeration. Comment the declaration and
implementation accordingly to help the user understand the problem and
avoid its usage.

Fix regression with commit
903b40a soc/intel: Replace uses of dev_find_slot()
Platforms where FSP hides PCI devices before enumeration
may halt with error message 'PCI: dev is NULL!'.
The workaround here is to print an error message revealing
the faulty source code function and revert to old behaviour
of dev_find_slot().

This function is duplicated in many AMD northbridge files, and all
the definitions have started to diverge somewhat. This moves a single
copy into device utils and deletes the rest. The function definition
from nb/amd/amdfam10 was chosen to be kept, since it contains several
fixes from commit 59d609217b (AMD fam10: Fix add_more_links) that
the others don't have.
For the ease of diffing, the checkpatch lints and other small cleanups
will be done in a follow-up patch.

Semantics of dev_find_slot() are ill in the sense that
it only works after device enumeration has completed in
ramstage. Plan is to declare it as deprecated.
Introduce pcidev_on_root() and pcidev_path_on_root()
functions to replace cases where this was called with
static argument bus == 0. New implementation only walks
the root bus of the PCI tree, while old one walked
the entire linked list of devices.
Introduce pcidev_path_behind() to replace cases where
argument bus != 0. The required parent node is typically
one of the PCIe root functions that you locate using
pcidev_on_root() above.
New forms are safe to use with early devicetree and
before PCI bus numbers have been assigned.

This commit adds support for describing USB ports in devicetree.cb.
It allows a USB port location to be described in the tree with
configuration information, and ACPI code to be generated that
provides this information to the OS.
A new scan_usb_bus() is added that will scan bridges for devices so
a tree of ports and hubs can be created.
The device address is computed with a 'port type' and a 'port id'
which is flexible for SOC to handle depending on their specific USB
setup and allows USB2 and USB3 ports to be described separately.
For example a board may have devices on two ports, one with a USB2
device and one with a USB3 device, both of which are connected to an
xHCI controller with a root hub:
xHCI
|
RootHub

USB2[0] USB3[2]

device usb 2.0 on end
end
chip drivers/usb/acpi
register "name" = ""USB 3.0 Port 2""
device usb 3.2 on end
end
end
end

functions that operate on struct device. struct device is a known

The devicetree data structures have been available in more than just
ramstage and romstage. In order to provide clearer and consistent
semantics two new macros are provided:
1. DEVTREE_EARLY which is true when !ENV_RAMSTAGE
2. DEVTREE_CONST as a replacment for ROMSTAGE_CONST
The ROMSTAGE_CONST attribute is used in the source code to mark
the devicetree data structures as const in early stages even though
it's not just romstage. Therefore, rename the attribute to
DEVTREE_CONST as that's the actual usage. The only place where the
usage was not devicetree related is console_loglevel, but the same
name was used for consistency. Any stage that is not ramstage has
the const C attribute applied when DEVTREE_CONST is used.

scan_smbus routine does not perform any smbus specific operation. Thus,
rename the routine to scan_generic_bus so that it can be used by other
buses like SPI. Add a wrapper scan_smbus to allow other users of smbus
scan to continue working as before.

Add support for a new "SPI" device type in the devicetree to bind a
device on the SPI bus. Allow device to provide chip select number for
the device as a parameter.
Add spi_bus_operations with operation dev_to_bus which allows SoCs to
define a translation method for converting "struct device" into a unique
SPI bus number.

In order to support doing bus operations on an I2C device that is
described in the devicetree there needs to be some linkage of the
device and the existing opaque I2C controller bus number.
This is provided in a similar fashion to the existing SMBUS operations
but modified to fit within the existing I2C infrastructure.
Variants of the existing I2C helper functions are provided that will
obtain the bus number that corresponds to this device by looking for
the SOC-provided I2C bus operation structure to provide a function
that will make that translation.
For example an SOC using a PCI I2C controller at 0:15.0 could use:
soc/intel/.../i2c.c:
static int i2c_dev_to_bus(struct device *dev)
{
if (dev->path.pci.devfn == PCI_DEVFN(0x15, 0))
return 0;
return -1;
}
static struct i2c_bus_operation i2c_bus_ops = {
.dev_to_bus = &i2c_dev_to_bus
}
static struct device_operations i2c_dev_ops = {
.ops_i2c_bus = &i2c_bus_ops
...
}
With an I2C device on that bus at address 0x1a described in the tree:
devicetree.cb:
device pci 15.0 on # I2C0
chip drivers/i2c/sample
device i2c 1a.0 on end
end
end
That driver can then do I2C transactions with the device object
without needing to know that the SOC-specific bus number that this
I2C device lives on is "0".
For example it could read a version value from register address 0
with a byte transaction:
drivers/i2c/sample/sample.c:
static void i2c_sample_enable(struct device *dev)
{
uint8_t ver;
if (!i2c_dev_readb(dev, 0x00, &ver))
printk(BIOS_INFO, "I2C %s version 0x02x\n", dev_path(dev), ver);
}

Add a function to "struct device_operations" to return the ACPI name
for the device, and helper functions to find this name (either from
the device or its parent) and to build a fully qualified ACPI path
from the root device.
This addition will allow device drivers to generate their ACPI AML in
the SSDT at boot, with customization supplied by devicetree.cb,
instead of needing custom DSDT ASL for every mainboard.
The root device acpi_name is defined as "\\_SB" and is used to start
the path when building a fully qualified name.
This requires SOC support to provide handlers for returning the ACPI
name for devices that it owns, and those names must match the objects
declared in the DSDT. The handler can be done either in each device
driver or with a global handler for the entire SOC.
Simplified example of how this can be used for an i2c device declared
in devicetree.cb with:
chip soc/intel/skylake # "\_SB" (from root device)
device domain 0 on # "PCI0"
device pci 19.2 on # "I2C4"
chip drivers/i2c/test0
device i2c 1a.0 on end # "TST0"
end
end
end
end
And basic SSDT generating code in the device driver:
acpigen_write_scope(acpi_device_scope(dev));
acpigen_write_device(acpi_device_name(dev));
acpigen_write_string("_HID", "TEST0000");
acpigen_write_byte("_UID", 0);
acpigen_pop_len(); /* device */
acpigen_pop_len(); /* scope */
Will produce this ACPI code:
Scope (\_SB.PCI0.I2C4) {
Device (TST0) {
Name (_HID, "TEST0000")
Name (_UID, 0)
}
}
