Johan Hedberg says: ==================== pull request: bluetooth-next 2018-08-10 Here's one more (most likely last) bluetooth-next pull request for the 4.19 kernel. - Added support for MediaTek serial Bluetooth devices - Initial skeleton for controller-side address resolution support - Fix BT_HCIUART_RTL related Kconfig dependencies - A few other minor fixes/cleanups Please let me know if there are any issues pulling. Thanks. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

MediaTek SoC built-in Bluetooth Devices
|
||||
==================================
|
||||
|
||||
This device is a serial attached device to BTIF device and thus it must be a
|
||||
child node of the serial node with BTIF. The dt-bindings details for BTIF
|
||||
device can be known via Documentation/devicetree/bindings/serial/8250.txt.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible: Must be
|
||||
"mediatek,mt7622-bluetooth": for MT7622 SoC
|
||||
- clocks: Should be the clock specifiers corresponding to the entry in
|
||||
clock-names property.
|
||||
- clock-names: Should contain "ref" entries.
|
||||
- power-domains: Phandle to the power domain that the device is part of
|
||||
|
||||
Example:
|
||||
|
||||
btif: serial@1100c000 {
|
||||
compatible = "mediatek,mt7622-btif",
|
||||
"mediatek,mtk-btif";
|
||||
reg = <0 0x1100c000 0 0x1000>;
|
||||
interrupts = <GIC_SPI 90 IRQ_TYPE_LEVEL_LOW>;
|
||||
clocks = <&pericfg CLK_PERI_BTIF_PD>;
|
||||
clock-names = "main";
|
||||
reg-shift = <2>;
|
||||
reg-io-width = <4>;
|
||||
|
||||
bluetooth {
|
||||
compatible = "mediatek,mt7622-bluetooth";
|
||||
power-domains = <&scpsys MT7622_POWER_DOMAIN_WB>;
|
||||
clocks = <&clk25m>;
|
||||
clock-names = "ref";
|
||||
};
|
||||
};
