platform/chrome: cros_ec_sensorhub: simplify getting .driver_data

2021-09-27T07:18:58Z

We should get 'driver_data' from 'struct device' directly. Going via platform_device is an unneeded step back and forth. Signed-off-by: Wolfram Sang Signed-off-by: Enric Balletbo i Serra Link: https://lore.kernel.org/r/20210920090522.23784-9-wsa+renesas@sang-engineering.com

platform/chrome: cros_ec_sensorhub: Allocate sensorhub resource before claiming sensors

2020-04-29T21:17:45Z

Allocate callbacks array before enumerating the sensors: The probe routine for these sensors (for instance cros_ec_sensors_probe) can be called within the sensorhub probe routine (cros_ec_sensors_probe()) Fixes: 145d59baff594 ("platform/chrome: cros_ec_sensorhub: Add FIFO support") Signed-off-by: Gwendal Grignou Reported-by: Douglas Anderson Tested-by: Douglas Anderson Signed-off-by: Enric Balletbo i Serra

platform/chrome: cros_ec_sensorhub: Add FIFO support

2020-03-28T21:04:32Z

cros_ec_sensorhub registers a listener and query motion sense FIFO, spread to iio sensors registers. To test, we can use libiio: iiod& iio_readdev -u ip:localhost -T 10000 -s 25 -b 16 cros-ec-gyro | od -x Signed-off-by: Gwendal Grignou Reviewed-by: Jonathan Cameron Acked-by: Andy Shevchenko Signed-off-by: Enric Balletbo i Serra

platform/chrome: cros_ec_sensorhub: Add the number of sensors in sensorhub

2020-03-28T21:04:32Z

To better manage resources, store the number of sensors reported by the EC. Signed-off-by: Gwendal Grignou Signed-off-by: Enric Balletbo i Serra

cros_ec: treewide: Remove 'include/linux/mfd/cros_ec.h'

2020-01-07T16:36:46Z

This header file now only includes the cros_ec_dev struct, however, is the 'include/linux/platform_data/cros_ec_proto.h' who contains the definition of all the Chrome OS EC related structs. There is no reason to have a separate include for this struct so move to the place where other structs are defined. That way, we can remove the include itself, but also simplify the common pattern #include #include for a single include #include The changes to remove the cros_ec.h include were generated with the following shell script: git grep -l "" | xargs sed -i '//d' Signed-off-by: Enric Balletbo i Serra Acked-by: Lee Jones Acked-by: Alexandre Belloni Acked-by: Jonathan Cameron Acked-by: Sebastian Reichel Acked-by: Hans Verkuil

iio / platform: cros_ec: Add cros-ec-sensorhub driver

2019-11-21T10:23:14Z

Similar to HID sensor stack, the new driver sits between cros-ec-dev and the IIO device drivers: The EC based IIO device topology would be: iio:device1 -> ...0/0000:00:1f.0/PNP0C09:00/GOOG0004:00/cros-ec-dev.6.auto/ cros-ec-sensorhub.7.auto/ cros-ec-accel.15.auto/ iio:device1 It will be expanded to control EC sensor FIFO.
