Jonathan Cameron	6c5bffa80e	iio:accel: drop assign iio_info.driver_module and iio_trigger_ops.owner The equivalent of both of these are now done via macro magic when the relevant register calls are made. The actual structure elements will shortly go away. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Lars-Peter Clausen <lars@metafoo.de>	2017-08-22 21:22:40 +01:00
Hans de Goede	1696566f99	iio: accel: mxc6255: Fix chip-id check The initial commit adding support for the mxc6225 assumed the mxc6225 has a chip-id of 0xe5 based on testing on a single Allwinner A23 tablet with a mxc6225. Testing on a bunch of other Allwinner tablets have shown that the chip-id for the mxc6225 is not constant. A datasheet for the MXC6255 which I've found online says that bits 7 and 6 of the chip-id register are undefined (for the mxc6255), testing on 5 different tablets with a mxc6225 has found the following ids: 0x25, 0x45, 0x65, 0x85, 0xe5. So it seems that for the mxc6225 bits 7, 6 and 5 of the chip-id register are undefined. This commit adjusts the chip-id check so that the mxc6255 driver properly recognizes the mxc6225 in all these tablets.

Hans de Goede	06777c562a	iio: accel: mxc6255 add support for the mxc6225 The mxc6225 is fully compatible with the existing mxc6255 driver, add support for it. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>	2016-09-05 21:18:16 +01:00
Teodora Baluta	75b6548f17	iio: accel: add support for Memsic MXC6255XC sensor This patch adds a minimal implementation for the Memsic MXC6255XC orientation sensing accelerometer. The supported operations are reading raw acceleration values for X/Y axis that can be scaled using the exposed scale.
