Ok looks okay overall but you are dropping my BME280 part changes here -> https://git.kernel.org/cgit/linux/kernel/git/jic23/iio.git/commit/?h=testing&id=14beaa8f5ab11b881c5e822e2474f5278d0946d5 > > Linus Walleij (9): > iio: pressure: bmp280: augment DT bindings > iio: pressure: bmp280: support device tree initialization > iio: pressure: bmp280: add reset GPIO line handling > iio: pressure: bmp280: support optional supply regulators > iio: pressure: bmp280: split driver in logical parts > iio: pressure: bmp280: split off an I2C Kconfig entry > iio: pressure: bmp280: add SPI interface driver > iio: pressure: bmp280: add support for the BMP058 EOC interrupt > iio: pressure: bmp280: read calibration data once > > .../devicetree/bindings/iio/pressure/bmp085.txt | 11 +- > drivers/iio/pressure/Kconfig | 27 +- > drivers/iio/pressure/Makefile | 3 + > drivers/iio/pressure/{bmp280.c => bmp280-core.c} | 428 ++++++++------------- > drivers/iio/pressure/bmp280-i2c.c | 79 ++++ > drivers/iio/pressure/bmp280-regmap.c | 78 ++++ > drivers/iio/pressure/bmp280-spi.c | 79 ++++ > drivers/iio/pressure/bmp280.h | 86 +++++ > 8 files changed, 526 insertions(+), 265 deletions(-) > rename drivers/iio/pressure/{bmp280.c => bmp280-core.c} (70%) > create mode 100644 drivers/iio/pressure/bmp280-i2c.c > create mode 100644 drivers/iio/pressure/bmp280-regmap.c > create mode 100644 drivers/iio/pressure/bmp280-spi.c > create mode 100644 drivers/iio/pressure/bmp280.h > > -- > 2.4.11 > > -- > To unsubscribe from this list: send the line "unsubscribe linux-iio" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
