[PATCH v5 1/2] gpio: tps65219: Update _IDX & _OFFSET macro prefix

There is a newer version of this series
[PATCH v5 1/2] gpio: tps65219: Update _IDX & _OFFSET macro prefix
Posted by Shree Ramamoorthy 7 months, 1 week ago 
TPS65215 and TPS65219 are overlapping PMIC devices. While their regulator
features differe, the GPIO features are the same. In the TPS65219 MFD
driver, the 2 PMICs share the same "tps65219-gpio" compatible string to
limit support for TPS65215 in this GPIO driver to comments.

The TPS6521X_GPIO0_IDX and TPS6521X_GPIO0_OFFSET macro name prefixes are
updated to indicate these macros apply to both PMICs.
