Hi everyone, This patch series adds device tree support to rfkill-gpio, and fixes some issues I ran into. This is so we can define and control RF devices through the device tree, such as the Broadcom BCM20710 UART-based Bluetooth device found on the CubieTruck. The series is based on Heikki's rfkill-gpio cleanup patches [1], applied on 3.15-rc1. Kudos to Heikki for paving the way. [1] https://lkml.org/lkml/2014/4/1/451 The device tree bindings are much better than was defined in the RFC series I sent a few months earlier [2], due to cleanups by Heikki, and named gpios (via gpio-names) implemented in the first two patches. Hopefully this will satisfy everyone. [2] https://lkml.org/lkml/2014/1/17/31 The CubieTruck uses a non-default clock rate oscillator for the BCM20710 device. As the datasheet states, a precise 32.768 KHz low power clock must be provided at power on for the device to detect the correct clock rate of the main oscillator. Hence the need for the "clock-frequency" property. The first 2 patches should go through the gpio tree. The 4 rfkill-gpio patches should go through the same tree that Heikki's patches are in. Maxime, can you take the last one? A big thanks to everyone who gave reviews and suggestions. Changes since RFC: - Dropped gpio name buffer fix patch (not needed after cleanup patches) - New gpios/gpio-names support for device trees - Simplify device tree bindings due to name cleanup and gpio-names support Cheers ChenYu Chen-Yu Tsai (7): gpiolib: gpiolib-of: Implement device tree gpio-names based lookup gpiolib: Support purely name based gpiod lookup in device trees net: rfkill: gpio: use clk_prepare_enable/clk_disable_unprepare net: rfkill: gpio: fix reversed clock enable state net: rfkill: gpio: add device tree support net: rfkill: gpio: add clock-frequency device tree property ARM: sun7i: cubietruck: enable bluetooth module .../devicetree/bindings/rfkill/rfkill-gpio.txt | 26 ++++++++++++ arch/arm/boot/dts/sun7i-a20-cubietruck.dts | 25 +++++++++++ drivers/gpio/gpiolib-of.c | 48 ++++++++++++++++++++++ drivers/gpio/gpiolib.c | 9 +++- include/linux/of_gpio.h | 3 ++ net/rfkill/rfkill-gpio.c | 34 +++++++++++++-- 6 files changed, 140 insertions(+), 5 deletions(-) create mode 100644 Documentation/devicetree/bindings/rfkill/rfkill-gpio.txt -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
