The goal was to isolate reset phandles to a single patch. The series with this patch dropped works because resets in their default state are deasserted, so this isn't a fix. And it allows testing the series on hardware with only the base platform series, which I found useful. Noted, I'll be squashed for next revision.

The series That was what you did, not the goal. If that's the goal, then it is clearly wrong. > with this patch dropped works because resets in their default state are > deasserted, so this isn't a fix.

Anyway, commits must be logical chunks, so one chunk is to add I2C controllers, not "part of I2C controllers". DTS is also independent of drivers (and it will go via different trees!), so whatever dependency you think of, it does not exist. Best regards, Krzysztof

My reasoning was focused on my point-of-view as a contributor and tester of the series. Your explanation makes sense; I had never thought this through from the maintainer's POV.

Add resets properties to each I2C controller. This depends on the reset-eyeq5 platform reset controller driver. Signed-off-by: Théo Lebrun <theo.lebrun@bootlin.com> --- arch/mips/boot/dts/mobileye/eyeq5.dtsi | 5 +++++ 1 file changed, 5 insertions(+)
