dt-bindings: Convert the BCM4329 bindings to YAML and extend
This converts the BCM4329 family bindings to YAML schema, and extends and fixes the bindings like this: - Name the bindings after the first chip (BCM4329) since wildcards like 43xx are nowadays frowned upon by the DT binding reviewers. We call this the "BCM4329 family" - Add compatible strings for all the variants that seem to exist in the wild. (Derived from firmware listings.) - Support specific-to-generic compatible strings (as already in use in DTS files). - Add required reg property (SDIO function number) - Add reset-gpios property (some systems wire this to a GPIO line). - I have only listed Arend as maintainer for now, volunteers can be added.

Broadcom BCM43xx Fullmac wireless SDIO devices
|
||||
|
||||
This node provides properties for controlling the Broadcom wireless device. The
|
||||
node is expected to be specified as a child node to the SDIO controller that
|
||||
connects the device to the system.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : Should be "brcm,bcm4329-fmac".
|
||||
|
||||
Optional properties:
|
||||
- brcm,drive-strength : drive strength used for SDIO pins on device in mA
|
||||
(default = 6).
|
||||
- interrupts : specifies attributes for the out-of-band interrupt (host-wake).
|
||||
When not specified the device will use in-band SDIO interrupts.
|
||||
- interrupt-names : name of the out-of-band interrupt, which must be set
|
||||
to "host-wake".
|
||||
|
||||
Example:
|
||||
|
||||
mmc3: mmc@1c12000 {
|
||||
#address-cells = <1>;
|
||||
#size-cells = <0>;
|
||||
|
||||
pinctrl-names = "default";
|
||||
pinctrl-0 = <&mmc3_pins_a>;
|
||||
vmmc-supply = <®_vmmc3>;
|
||||
bus-width = <4>;
|
||||
non-removable;
|
||||
|
||||
brcmf: wifi@1 {
|
||||
reg = <1>;
|
||||
compatible = "brcm,bcm4329-fmac";
|
||||
interrupt-parent = <&pio>;
|
||||
interrupts = <10 8>; /* PH10 / EINT10 */
|
||||
interrupt-names = "host-wake";
|
||||
};

||||
};
