Commit Message

Linus Walleij March 15, 2021, 10:59 a.m. UTC
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.

ChangeLog v1->v2:
- Specify specific-to-generic compatible strings such as
  "brcm,bcm4334-fmac", "brcm,bcm4329-fmac"
- Also allow just "brcm,bcm4329-fmac" for legacy platforms.
- Use this scheme in the example.

-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 = <&reg_vmmc3>;
-	bus-width = <4>;
-	non-removable;
