[PATCH v2 3/4] firmware/qcom_scm: Add scm call to handle smmu errata

2018-09-10 Thread Vivek Gautam
Qcom's smmu-500 needs to toggle wait-for-safe sequence to handle TLB invalidation sync's. Few firmwares allow doing that through SCM interface. Add API to toggle wait for safe from firmware through a SCM call. Signed-off-by: Vivek Gautam --- drivers/firmware/qcom_scm-32.c | 5 +
