From a576a849d5f33356e0d8fd3eae4fbaf8869417e5 Mon Sep 17 00:00:00 2001 From: Lorenzo Pieralisi Date: Tue, 5 Aug 2025 15:34:43 +0200 Subject: of/irq: Convert of_msi_map_id() callers to of_msi_xlate() With the introduction of the of_msi_xlate() function, the OF layer provides an API to map a device ID and retrieve the MSI controller node the ID is mapped to with a single call. of_msi_map_id() is currently used to map a deviceID to a specific MSI controller node; of_msi_xlate() can be used for that purpose too, there is no need to keep the two functions. Convert of_msi_map_id() to of_msi_xlate() calls and update the of_msi_xlate() documentation to describe how the struct device_node pointer passed in should be set-up to either provide the MSI controller node target or receive its pointer upon mapping completion.
