Hi, This is an RFC patch adding DT support to the si4713 radio transmitter i2c driver. The changes can be summarized as follows: * Move regulator information back into the driver. The regulators needed are documented in the chip and have nothing to do with boarddata. Instead devm_regulator_get_optional and errors are handled quite loosely now. Maybe the USB driver should provide dummy regulators. * GPIO handling is updated to gpiod consumer interface, resulting in a driver cleanup and easy DT handling * The driver is updated to use managed resources wherever possible So much about the nice stuff. But there is also * Instantiation of the platform device from the i2c (sub-)device. Since DT is not supposed to contain linuxisms the device is a simple i2c node resulting in the i2c probe function being called. Thus registering the main v4l device must happen from there. Tested: * Compilation on torvalds/linux.git:master * Booting in DT mode * Some simply driver queries using v4l2-ctl Not tested: * The USB driver, since I do not own the USB dongle * The legacy platform code (only DT boot has been tested). (The legacy platform code is supposed to removed in the near future anyways) -- Sebastian Sebastian Reichel (2): [media] si4713: add Device Tree support [media] Ad DT binding documentation for si4713 Documentation/devicetree/bindings/media/si4713.txt | 30 ++++ arch/arm/mach-omap2/board-rx51-peripherals.c | 67 ++++----- drivers/media/radio/si4713/radio-platform-si4713.c | 28 +--- drivers/media/radio/si4713/si4713.c | 166 +++++++++++++-------- drivers/media/radio/si4713/si4713.h | 15 +- include/media/radio-si4713.h | 30 ---- include/media/si4713.h | 4 +- 7 files changed, 183 insertions(+), 157 deletions(-) create mode 100644 Documentation/devicetree/bindings/media/si4713.txt delete mode 100644 include/media/radio-si4713.h -- 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
