Re: [PATCH 2/2] bootcount: Add driver model I2C driver

Hi Simon, maybe you can give me a hint on how to implement this cleanly in driver model? To sum it up, I'd like to have a phandle pointing to *any* I2C device, not knowing which UCLASS actually fits. Then the device and the parent bus should be probed/prepared such that dm_i2c_read() can be used.

[PATCH 2/2] bootcount: Add driver model I2C driver

This adds a generic I2C bootcounter adhering to driver model to replace the previously removed legacy implementation. There is no change in functionality, it can be used on any I2C device. The device tree configuration may look like this for example: bootcount { compatible
