This patch series adds support for attaching external sensors to INV MPU6050
secondary I2C interface (acting as an I2C bus).
First patch fixes a bug when using ACPI, the second one moves the interrupt out
of probe trigger code preparing the third patch which actually does $Subject.
I2C secondary bus can support up to 5 slaves. Slaves 0-3 have a common way
of operation while the 4 one is completely different. This patch series
only implements support for the 4th slave because it has a cleaner interface
(although less efficent for bulk transfer) and also provides a way of
signalling when data recevied from slave is available.
Ge,
In order to prepare support for slaves 0-3 we need to find the answer for
the following questions:
* when doing a read transaction after preparing I2C address, I2C
remote register, etc how do we know when to read for available data?
* how can we benefit from INV MPU6050 FIFO in case of external sensors?
(will look into in-kernel buffer consumers)
