From f1a325d2812797166c744ff7ffb2ccbafbac20ad Mon Sep 17 00:00:00 2001 From: Praveen Talari Date: Fri, 27 Feb 2026 11:45:37 +0530 Subject: soc: qcom: geni-se: Introduce helper API for attaching power domains The GENI Serial Engine drivers (I2C, SPI, and SERIAL) currently handle the attachment of power domains. This often leads to duplicated code logic across different driver probe functions. Introduce a new helper API, geni_se_domain_attach(), to centralize the logic for attaching "power" and "perf" domains to the GENI SE device.
