From f737020d24e47d6e8b893a2fee2b43268a6af629 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Fri, 6 Oct 2023 12:03:20 +0200 Subject: [PATCH] Input: max77693-haptic - add device-tree compatible strings Add the needed device-tree compatible strings to the MAX77693 haptic driver, so it can be automatically loaded when compiled as a kernel module and given device-tree contains separate (i.e. 'motor-driver') node under the main PMIC node. When device is instantiated from device-tree, the driver data cannot be read via platform_get_device_id(), so get device type from the parent MFD device instead, what works for both cases.
