The LRADC units in i.MX23 and i.MX28 differ and we need to distinguish both SoC variants in order to make the touchscreen work on i.MX23 Signed-off-by:

The delay units inside the LRADC depend on the presence of a 2 kHz clock. This change enables the clock to be able to use the delay unit for the touchscreen part of the driver. Signed-off-by:

The documentation says that the result of raw * scale should be in microvolts, but in reallity all drivers actually report the scale so that the result is in millivolts. So update the documentation to match reallity. Signed-off-by:

Call hid_sensor_hub_device_open when user space opens device and call hid_sensor_hub_device_close when device is closed. This helps in saving power. Signed-off-by:

Don't call hid_open_device till there is actually an user. This saves power by not opening underlying transport for HID. Also close device if there are no active mfd client using HID sensor hub. Signed-off-by:

Turns out that LL_MRF_RETURN is "void" so loop_make_request() would fall through to the error path for a successful call. Either this never matters, or the error path really doesn't do anything. Fix it up to do what the code is written to look like it is doing, if that really is what it should be doing is another story...
