From e9c11c6e3a0e93903f5a13f8d2f97ae1bba512e1 Mon Sep 17 00:00:00 2001 From: Caleb Connolly Date: Fri, 29 Apr 2022 23:08:57 +0100 Subject: mfd: qcom-spmi-pmic: expose the PMIC revid information to clients Some PMIC functions such as the RRADC need to be aware of the PMIC chip revision information to implement errata or otherwise adjust behaviour, export the PMIC information to enable this. This is specifically required to enable the RRADC to adjust coefficients based on which chip fab the PMIC was produced in, this can vary per unique device and therefore has to be read at runtime.
