From b26b4e91700ff45d033eeaac91597d6d479378a4 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 30 Jun 2016 03:48:51 +0200 Subject: iio: pressure: bmp280: add SPI interface driver This patch mimics the SPI functionality found in the misc driver in drivers/misc/bh085-spi.c to make it possible to reuse the existing BMP280/BMP180/BMP085 driver with all clients of the other driver. The adoption is straight-forward since like the other driver, it is a simple matter of using regmap. This driver is also so obviously inspired/copied from the old misc driver in drivers/misc/bmp085.c that I just took the liberty to add in the authors of the other drivers + self in the core driver file. The MISC driver also supports a variant named "BMP181" so include that here to be complete in comparison to the old driver. The bus mapping code for SPI was written by Akinobu Mita.
