Merge tag 'memory-controller-drv-tegra-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl into arm/drivers
Memory controller drivers for v5.13 - Tegra SoC 1. Few cleanups. 2. Add debug statistics to Tegra20 memory controller. 3. Update bindings and convert to dtschema. This update is not backwards compatible (ABI break) however the broken part was added recently (v5.11) and there are no users of it yet. * tag 'memory-controller-drv-tegra-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl: dt-bindings: memory: tegra20: mc: Convert to schema dt-bindings: memory: tegra124: emc: Replace core regulator with power domain dt-bindings: memory: tegra30: emc: Replace core regulator with power domain dt-bindings: memory: tegra20: emc: Replace core regulator with power domain memory: tegra: Print out info-level once per driver probe memory: tegra20: Protect debug code with a lock memory: tegra20: Correct comment to MC_STAT registers writes memory: tegra20: Add debug statistics memory: tegra: replace DEFINE_SIMPLE_ATTRIBUTE with DEFINE_DEBUGFS_ATTRIBUTE Link: https://lore.kernel.org/r/20210407161333.73013-2-krzysztof.kozlowski@canonical.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>
