PM: AVS: qcom-cpr: Fix an error handling path in cpr_probe()

2023-02-01T07:23:11Z

[ Upstream commit 6049aae52392539e505bfb8ccbcff3c26f1d2f0b ] If an error occurs after a successful pm_genpd_init() call, it should be undone by a corresponding pm_genpd_remove(). Add the missing call in the error handling path, as already done in the remove function.

PM: AVS: qcom-cpr: Use div64_ul instead of do_div

2022-01-27T09:54:17Z

[ Upstream commit 92c550f9ffd2884bb5def52b5c0485a35e452784 ] do_div() does a 64-by-32 division. Here the divisor is an unsigned long which on some platforms is 64 bit wide. So use div64_ul instead of do_div to avoid a possible truncation.

PM: AVS: qcom-cpr: Move the driver to the qcom specific drivers

2020-10-22T16:38:21Z

The avs drivers are all SoC specific drivers that doesn't share any code. Instead they are located in a directory, mostly to keep similar functionality together. From a maintenance point of view, it makes better sense to collect SoC specific drivers like these, into the SoC specific directories. Therefore, let's move the qcom-cpr driver to the qcom directory.
