PM / devfreq: tegra20: Deprecate in a favor of emc-stat based driver

2020-11-23T07:01:13Z

Remove tegra20-devfreq in order to replace it with a EMC_STAT based devfreq driver. Previously we were going to use MC_STAT based tegra20-devfreq driver because EMC_STAT wasn't working properly, but now that problem is resolved. This resolves complications imposed by the removed driver since it was depending on both EMC and MC drivers simultaneously.

PM / devfreq: tegra20: Silence deferred probe error

2020-10-26T03:15:43Z

Tegra EMC driver was turned into a regular kernel driver, meaning that it could be compiled as a loadable kernel module now. Hence EMC clock isn't guaranteed to be available and clk_get("emc") may return -EPROBE_DEFER. Let's silence the deferred probe error.
