2020-11-26memory: tegra20: Support interconnect frameworkDmitry Osipenko3-4/+386
Now Internal and External Memory Controllers are memory interconnection providers. This allows us to use interconnect API for tuning of memory configuration. EMC driver now supports OPPs and DVFS.

2020-11-26memory: tegra20-emc: Continue probing if timings are missing in device-treeDmitry Osipenko1-18/+16
EMC driver will become mandatory after turning it into interconnect provider because interconnect users, like display controller driver, will fail to probe using newer device-trees that have interconnect properties. Thus make EMC driver to probe even if timings are missing in device-tree.

2020-11-26memory: tegra-mc: Add interconnect frameworkDmitry Osipenko4-0/+140
Add common SoC-agnostic ICC framework which turns Tegra Memory Controller into a memory interconnection provider. This allows us to use interconnect API for tuning of memory configurations.

2020-11-26memory: tegra: Add missing latency allowness entry for Page Table CacheDmitry Osipenko3-0/+18
Add missing PTC memory client latency allowness entry to the Tegra MC drivers. This prevents erroneous clearing of MC_INTSTATUS 0x0 register during of the LA programming in tegra_mc_setup_latency_allowance() due to the missing entry. Note that this patch doesn't fix any known problems.
