2021-08-03regulator: sy8824x: Enable REGCACHE_FLATJisheng Zhang1-1/+15
Enable regmap cache to reduce i2c transactions and corresponding interrupts if regulator is accessed frequently. Since the register map is small -- there's only one register in sy8824c and sy8824e, there are only two registers in sy20276 and sy20278, so we use a FLAT regmap cache.

2020-01-13regulator: Convert i2c drivers to use .probe_newAxel Lin1-3/+2
Use the new .probe_new for i2c drivers. These drivers do not use const struct i2c_device_id * argument, so convert them to utilise the simplified i2c driver registration.

2019-08-27regulator: add support for SY8824C regulatorJisheng Zhang1-0/+192
SY8824C is an I2C attached single output regulator made by Silergy Corp, which is used on several Synaptics berlin platforms to control the power supply of the ARM cores. Add a driver for it.
