mfd: tps65219: Add support for TI TPS65215 PMIC
Use chip ID and chip_data struct to differentiate between devices in probe(). Add TPS65215 resource information. Update descriptions and copyright information to reflect the driver supports 2 PMIC devices. Signed-off-by: Shree Ramamoorthy <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Lee Jones <[email protected]>
