From 90486af5e0f7334091b94264a84713611933e97e Mon Sep 17 00:00:00 2001 From: Enric Balletbo i Serra Date: Wed, 8 May 2019 11:19:55 +0200 Subject: mfd: cros_ec: Instantiate properly CrOS FP MCU device Support Fingerprint MCU as a special of CrOS EC devices. The current FP MCU uses the same EC SPI protocol v3 as other CrOS EC devices on a SPI bus. When a MCU has fingerprint support (aka EC_FEATURE_FINGERPRINT), it is instantiated as a special CrOS EC device with device name 'cros_fp'. So regardless of the probing order between the actual cros_ec and cros_fp, the userspace and other kernel drivers should not confuse them.
