dt-bindings: net: broadcom-bluetooth: Add conditional constraints

2022-07-22T00:11:44Z

Add conditional constraint to make property "reset-gpios" available only for compatible devices acually having the reset pin. Make property "brcm,requires-autobaud-mode" depend on property "shutdown-gpios" as the shutdown pin is required to enter autobaud mode. I looked at all compatible devices and compiled the matrix below before formulating the conditional constraint. This was a pure paper exercise and no verification testing has been performed. d e v h i o c s s e t h - - u w w v t r a a v d d e k k b d o s e e a i w e u u t o n t p p - - - - - - s s g g g g u u p p p p t p p i i i i x l p p o o o o c p l l s s s s o o y y --------------------------------------- brcm,bcm20702a1 X X X X X X X X brcm,bcm4329-bt X X X X X X X X brcm,bcm4330-bt X X X X X X X X brcm,bcm4334-bt X - X X X X X X brcm,bcm43438-bt X - X X X X X X brcm,bcm4345c5 X - X X X X X X brcm,bcm43540-bt X - X X X X X X brcm,bcm4335a0 X - X X X X X X brcm,bcm4349-bt X - X X X X X X infineon,cyw55572-bt X - X X X X X X Signed-off-by: Hakan Jansson Reviewed-by: Rob Herring Reviewed-by: Linus Walleij Signed-off-by: Luiz Augusto von Dentz

dt-bindings: net: broadcom-bluetooth: Add property for autobaud mode

2022-07-22T00:04:26Z

Add property, "brcm,requires-autobaud-mode", to enable autobaud mode selection. Some devices (e.g. CYW5557x) require autobaud mode to enable FW loading. Autobaud mode can also be required on some boards where the controller device is using a non-standard baud rate when first powered on.

dt-bindings: bluetooth: broadcom: Fix clocks check

2021-10-12T14:05:34Z

The original binding was mentioning that valid values for the clocks and clock-names property were one or two clocks from extclk, txco and lpo, with extclk being deprecated in favor of txco. However, the current binding lists a valid array as extclk, txco and lpo, with either one or two items. While this looks similar, it actually enforces that all the device trees use either ["extclk"], or ["extclk", "txco"]. That doesn't make much sense, since the two clocks are said to be equivalent, with one superseeding the other. lpo is also not a valid clock anymore, and would be as the third clock of the list, while we could have only this clock in the previous binding (and in DTs). Let's rework the clock clause to allow to have either: - extclk, and mark it a deprecated - txco alone - lpo alone - txco, lpo While ["extclk", "lpo"] wouldn't be valid, it wasn't found in any device tree so it's not an issue in practice. Similarly, ["lpo", "txco"] is still considered invalid, but it's generally considered as a best practice to fix the order of clocks. Cc: "David S.

Bluetooth: btbcm: Rewrite bindings in YAML and add reset

2021-03-08T09:25:49Z

This rewrites the Broadcom bluetooth bindings in YAML and adds a GPIO handle for the BT_RST_N line as used on some platforms. The Ingenic UART binding was using this binding in its example DTS fragment, however mistakenly using "vcc-supply" for what is called "vbat-supply". The proper DTS files and the code in the kernel all use "vbat-supply" so fix up the example in this patch so we ge a clean check.
