[PATCH v2 4/6] power: supply: bq27xxx: add separate flag for single SoC register

From: Krzysztof Kozlowski
Date: Sat Sep 19 2020 - 10:04:48 EST


bq27000, bq27010 and upcoming bq34z100 have a single byte SoC
register. However except this similarity, bq34z100 is quite different
than bq27000/bq27010, so flag BQ27XXX_O_ZERO cannot be reused here. Add
a new bit flag describing that SoC is a single byte register.

No functional change for bq27000 and bq27010.
