Merge tag 'memory-controller-drv-tegra-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl into arm/drivers
Memory controller drivers for v5.12 - Tegra SoC
1. Make the tegra124-emc driver modular.
2. Add interconnect support to Tegra124 memory controller drivers.
3. Minor fixes.
* tag 'memory-controller-drv-tegra-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl:
memory: tegra: Remove calls to dev_pm_opp_set_clkname()
memory: tegra: Check whether reset is already asserted
memory: tegra124: Support interconnect framework
memory: tegra124-emc: Continue probing if timings are missing in device-tree
memory: tegra124-emc: Make driver modular
