From ce310bd70414392448d7f8301e0817151555a34e Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Mon, 3 Aug 2020 15:57:12 +0300 Subject: dmaengine: ti: k3-psil: Use soc_device_match to get the psil map Instead of separate of_machine_is_compatible() it is better to use soc_device_match() and soc_device_attribute struct to get the PSI-L map for the booted device. By using soc_device_match() it is easier to add support for new devices.
