22 LT7182S is a Dual Channel 6A, 20V PolyPhase Step-Down Silent Switcher with
23 Digital Power System Management support.
29 This driver does not probe for PMBus devices. You will have to instantiate
32 Example: the following commands will load the driver for a LT7182S
33 at address 0x4f on I2C bus #4::
36 # echo lt7182s 0x4f > /sys/bus/i2c/devices/i2c-4/new_device
38 It can also be instantiated by declaring an entry in device tree.
