From: "Lad, Prabhakar" <[email protected]>
The first patch of the series adds supports for asynchronous subdev
registration for ths8200 driver, and the second patch of the series
adds OF support the driver.
Lad, Prabhakar (2):
media: i2c: ths8200: support asynchronous probing
media: i2c: ths8200: add OF support
