Jens Kehne b1b15c7b24 mfd: da9063: Split chip variant reading in two bus transactions 
[ Upstream commit 9ac4890ac3 ]

We observed the initial probe of the da9063 failing in
da9063_get_device_type in about 30% of boots on a Xilinx ZynqMP based
board. The problem originates in da9063_i2c_blockreg_read, which uses
a single bus transaction to turn the register page and then read a
register. On the bus, this should translate to a write to register 0,
followed by a read to the target register, separated by a repeated
start. However, we found that after the write to register 0, the
controller sometimes continues directly with the register address of
the read request, without sending the chip address or a repeated start
in between, which makes the read request invalid.

To fix this, separate turning the page and reading the register into
two separate transactions. This brings the initialization code in line
with the rest of the driver, which uses register maps (which to my
knowledge do not use repeated starts after turning the page). This has
been included in our kernel for several months and was recently
included in a shipped product. For us, it reliably fixes the issue,
and we have not observed any new issues.

While the underlying problem is probably with the i2c controller or
its driver, I still propose a change here in the interest of
robustness: First, I'm not sure this issue can be fixed on the
controller side, since there are other issues related to repeated
start which can't (AR# 60695, AR# 61664). Second, similar problems
might exist with other controllers.
