Subject: i2c/tps65010: update for current i2c-omap
From: David Brownell <david-b@xxxxxxxxxxx>
This updates the TPS6501x driver to stop trying to use the faked-out I2C probe
protocol (never guaranteed to work), since the OMAP I2C driver merged to
kernel.org no longer tries to support it.
Until the I2C stack is updated to offer full driver model support from static
board-specific device tables, and is able to pass things like IRQ resources
and chip IDs, the only way to address this type of issue is for drivers to
have board-specific info kick in before registering the driver (for
addressing), and in the probe code (for other resources). So that's what this
patch adds.
