R-Car I2C is similar with SH7760 I2C.
But the SH7760 I2C driver had many workaround operations, since H/W had bugs.
Thus, it was pointless to keep compatible between SH7760 and R-Car I2C drivers.
This patch creates new Renesas R-Car I2C driver.

Hi Shubhrajyoti
Thank you for checking patch.
I create v2 patch and post it soon.
There is not big reason, but I would like to keep adap-retries for now.

Hi Morimoto
all H2/M2/E2/V2.
And, from HW team point of view, they don't want to create
same name but multi feature IP in same generation.
Creating and Testing new IP needs too much time / money / paper work.

rcar_i2c_init() initializes I2C device, but it should be called
*after* pm_runtime_get_sync(). Otherwise it outputs very hi speed
clock. This patch solved this issue,
This patch also removes pointless rcar_i2c_init()
from rcar_i2c

I tested this branch on Lagar and Salvator-X with Sound.
(Sound uses I2C for ak4642, ak4613, and CS2000)
Actually, above branch is missing some necessary sound patch,
but anyway, I2C works good for sound.

Do you mean you can call init() in callback ?
I don't care detail of design. But my concern was that
register value might be disappear during many
