I told you about this already.
If you want this set to be merged for v4.3 then you'll need commit
b4fe8ba ("regmap: Add generic macro to define regmap_irq") from my
tree.
You asked me to submit this to Mark Brown, I didn't realize you also
wanted me to use the one in your tree. Using yours will make my lines
over 80 chars and so it kind of defeats the purpose but I'll do it
for v4.
I asked two of you to upstream a generic incarnation of your
implementation. The other guy got there first. Now I want everyone
to use it instead of hand-rolling their own.
Got it.

+static struct i2c_driver tps65912_i2c_driver = {

+ .of_match_table = tps65912_i2c_of_match_table,

Why? tps65912_i2c_of_match_table is always compiled in.
But it needn't be.
This driver is DT only, would it make more sense to just add a dependency
on CONFIG_OF in the Kconfig?
Yes, that is the alternitive.
I don't see many other drivers that are DT
only doing this, the driver should compile just fine without OF enabled,
it just wont have DT functionality, so is it really dependent on OF?
Then it should be "depends on OF || COMPILE_TEST"
OK, I'll add this.
The of_match_ptr(x) macro looks to be useful when the x is conditionally
compiled in, but in my case the x (my of_device_id table) is always compiled.
