From 5b8a39dcf909a4723a58e424ae1b0595d6f5032d Mon Sep 17 00:00:00 2001 From: Praveen Talari Date: Fri, 27 Feb 2026 11:45:34 +0530 Subject: soc: qcom: geni-se: Introduce helper API for resource initialization The GENI Serial Engine drivers (I2C, SPI, and SERIAL) currently duplicate code for initializing shared resources such as clocks and interconnect paths. Introduce a new helper API, geni_se_resources_init(), to centralize this initialization logic, improving modularity and simplifying the probe function.
