Merge tag 'memory-controller-drv-tegra-5.11-3' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl into arm/drivers
Memory controller drivers for v5.11 - Tegra SoC, part two
Continuation of work on Tegra SoC memory controllers towards adding
interconnect support and integration with devfreq.
This brings few more patches including one which removes/fixes annoying
warning if the DTS patches get applied. This is expected and only
informs that new features of Tegra memory controller drivers will not be
enabled however the warning itself could look worrying.
* tag 'memory-controller-drv-tegra-5.11-3' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl:
memory: tegra30: Support interconnect framework
memory: tegra20: Support hardware versioning and clean up OPP table initialization
dt-bindings: memory: tegra20-emc: Document opp-supported-hw property
