This adds an IIO magnetometer driver for the Yamaha YAS530 family of magnetometer/compass chips YAS530, YAS532 and YAS533. A quick survey of the source code released by different vendors reveal that we have these variants in the family with some deployments listed: * YAS529 MS-3C (2005 Samsung Aries) * YAS530 MS-3E (2011 Samsung Galaxy S Advance) * YAS532 MS-3R (2011 Samsung Galaxy S4) * YAS533 MS-3F (Vivo 1633, 1707, V3, Y21L) * (YAS534 is a magnetic switch) * YAS535 MS-6C * YAS536 MS-3W * YAS537 MS-3T (2015 Samsung Galaxy S6, Note 5) * YAS539 MS-3S (2018 Samsung Galaxy A7 SM-A750FN) The YAS529 is so significantly different from the YAS53x variants that it will require its own driver. The YAS537 and YAS539 have slightly different register sets but have strong similarities so a common driver patching this one will probably be reasonable. The source code for Samsung Galaxy A7's YAS539 is not that is significantly different from the YAS530 in the Galaxy S Advance, so I believe we will only need this one driver with quirks to handle all of them. The YAS539 is actively announced on Yamaha's devices site: https://device.yamaha.com/en/lsi/products/e_compass/ This is a driver written from scratch using buffered IIO and runtime PM handling regulators and reset. Thanks to Andy Shevchenko for great help in finding all the special kernel infrastructure functions and quirks during review of this driver.
