The old driver has two main deficencies:
i) No repeated start (Sr) condiction is possible, this makes it unusable
e.g. for most SMBus transfers.
ii) I/O was done with polling/busy waiting what caused over-/underruns
even at light system loads and clock speeds.
The new driver overcomes
The G45 datasheets explicitly states that setting the open drain property
on peripheral function gpios is not allowed. (How about other A91 chips?)

This driver has the following properties compared to the old driver:
1. Support for multiple interfaces.
2. Interrupt driven I/O as opposed to polling/busy waiting.
3. Support for _one_ repeated start (Sr) condition, which is enough
for most real-world applications including all SMBus transfer

Hi Thomas,
With the updated patch and the modified sensors-detect I have been
able to probe all ports and have not encountered the power issue
again. If no further issues are identified I will seperate the patch
Hi James,
Quite a long Cc list for such a trivial patch...

No, the platform device isn't deleted. The i2c adapters are deleted but

Can you please do also a separate patch for the device tree binding for
getting the GPIO pins for this controller?
Other than that thanks for doing this and:
