Subject: BCM2048 bluetooth connected over OMAP serial
Date: Wed, 10 Dec 2014 17:43:33 +0100 [thread overview]
Message-ID: <20141210164333.GA3154@amd> (raw)
Hi!
So, there's bluetooth chip that's connected to the SoC by UART and some
GPIOs. What would be right representation in the device tree?
Something like this?
bluetooth {
compatible = "broadcom,bcm2048";
uart = <&uart2>;
reset-gpios = <&gpio3 27 GPIO_ACTIVE_HIGH>; /* want 91 */
host-wakeup-gpios = <&gpio4 5 GPIO_ACTIVE_HIGH>; /* want 101 */
bluetooth-wakeup-gpios = <&gpio2 5 GPIO_ACTIVE_HIGH>; /* want 37 */
chip-type = <3>;
bt-sysclk = <2>;
reset-gpio-shared = <0>;
};
Is there some way to prevent OMAP tty driver from binding to the
device and exporting the device to userspace?
Best regards,
Pavel
