This change makes the names of Broadcom targets consistent by using the common notation based on SoC/CPU ID (which is used internally anyway), bcmXXXX instead of brcmXXXX. This is even used for target TITLE in make menuconfig already, only the short target name used brcm so far. Despite, since subtargets range from bcm2708 to bcm2711, it seems appropriate to use bcm27xx instead of bcm2708 (again, as already done for BOARDNAME). This also renames the packages brcm2708-userland and brcm2708-gpu-fw. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de> Acked-by: Álvaro Fernández Rojas <noltari@gmail.com>

Subject: [PATCH] dt-bindings: pci: Add DT docs for Brcmstb PCIe device
|
|
|
|
The DT bindings description of the Brcmstb PCIe device is described. This
|
|
node can be used by almost all Broadcom settop box chips, using
|
|
ARM, ARM64, or MIPS CPU architectures.

+Brcmstb PCIe Host Controller Device Tree Bindings
|
|
+
|
|
+Required Properties:
|
|
+- compatible
|
|
+ "brcm,bcm7425-pcie" -- for 7425 family MIPS-based SOCs.
|
|
+ "brcm,bcm7435-pcie" -- for 7435 family MIPS-based SOCs.
|
|
+ "brcm,bcm7445-pcie" -- for 7445 and later ARM based SOCs (not including
|
|
+ the 7278).
|
|
+ "brcm,bcm7278-pcie" -- for 7278 family ARM-based SOCs.
|
|
+
|
|
+- reg -- the register start address and length for the PCIe reg block.
|
|
+- interrupts -- two interrupts are specified; the first interrupt is for
|
|
+ the PCI host controller and the second is for MSI if the built-in
|
|
+ MSI controller is to be used.
|
|
+- interrupt-names -- names of the interrupts (above): "pcie" and "msi".
|
|
+- #address-cells -- set to <3>.
|
|
+- #size-cells -- set to <2>.
|
|
+- #interrupt-cells: set to <1>.
|
|
+- interrupt-map-mask and interrupt-map, standard PCI properties to define the
|
|
+ mapping of the PCIe interface to interrupt numbers.
|
|
+- ranges: ranges for the PCI memory and I/O regions.
|
|
+- linux,pci-domain -- should be unique per host controller.
|
|
+
|
|
+Optional Properties:
|
|
+- clocks -- phandle of pcie clock.
|
|
+- clock-names -- set to "sw_pcie" if clocks is used.
|
|
+- dma-ranges -- Specifies the inbound memory mapping regions when
|
|
+ an "identity map" is not possible.
|
|
+- msi-controller -- this property is typically specified to have the
|
|
+ PCIe controller use its internal MSI controller.
|
|
+- msi-parent -- set to use an external MSI interrupt controller.
|
|
+- brcm,enable-ssc -- (boolean) indicates usage of spread-spectrum clocking.
|
|
+- max-link-speed -- (integer) indicates desired generation of link:
|
|
+ 1 => 2.5 Gbps (gen1), 2 => 5.0 Gbps (gen2), 3 => 8.0 Gbps (gen3).
