In doing so, we can easily introduce SPI support and let regmap handle the rest. Recap of basic features: read_raw for x, y and z axes, scale. After applying this series, driver now supports the SPI protocol and enumeration of device via device tree. Changes from v4: [PATCH 1/4] * Update subject-prefix * Update node name from "adxl345@unit-address" to "accelerometer@unit-address" Patches 2-4 * Add Andy's Reviewed-by tag Changes from v3: [PATCH 1/4] * None [PATCH 2/4] * Keep intact I2C client structure which was deleted from v3 * Make use of regmap_get_device to retrieve struct device, use these for debugging prints instead of &client->dev. [PATCH 3/4] and [PATCH 4/4] * Revert to explicit and separate I2C and SPI configuration * Add OF match table, make it enumerable in ACPI environment (Andy's suggestion) Changes from v2: * Drop PATCH 4 iio: accel: adxl345: Add ACPI support * Add OF match table on both I2C and SPI files and document them Changes from v1: [PATCH 1/4] * Move other deletions from patch 2 in here -- make it clear what got deleted and/or modified that is hard to see previously * Introduce the driver header file "adxl345.h" here instead of doing it in the next patch * Completely omit traces of i2c_client and let this file (adxl345.c) mirror the core file on the next patch. * Improve debugging print about invalid device ID in probe. [PATCH 2/4] * Update Kconfig to Jonathan's preferred style * Improve similarity index from 78% to 100% (rename detection) [PATCH 4/4] * Correct acpi_device_id: ADX0345 -> ADS0345 Eva Rachel Retuya (4): dt-bindings: iio: accel: Document ADXL345 accelerometer binding iio: accel: adxl345: Use I2C regmap instead of direct I2C access iio: accel: adxl345: Split driver into core and I2C iio: accel: adxl345: Add SPI support .../devicetree/bindings/iio/accel/adxl345.txt | 38 +++++++++ drivers/iio/accel/Kconfig | 26 ++++++- drivers/iio/accel/Makefile | 4 +- drivers/iio/accel/adxl345.h | 18 +++++ drivers/iio/accel/{adxl345.c => adxl345_core.c} | 89 +++++++++------------- drivers/iio/accel/adxl345_i2c.c | 78 +++++++++++++++++++ drivers/iio/accel/adxl345_spi.c | 83 ++++++++++++++++++++ 7 files changed, 281 insertions(+), 55 deletions(-) create mode 100644 Documentation/devicetree/bindings/iio/accel/adxl345.txt create mode 100644 drivers/iio/accel/adxl345.h rename drivers/iio/accel/{adxl345.c => adxl345_core.c} (62%) create mode 100644 drivers/iio/accel/adxl345_i2c.c create mode 100644 drivers/iio/accel/adxl345_spi.c -- 2.7.4
