[PATCH V2 0/2] memory: tegra: Add Tegra238 memory controller support

Posted by Ashish Mhetre 1 month, 2 weeks ago

This series adds Memory Controller driver support for the Tegra238 SoC.

Tegra238 is similar to Tegra234 but with a reduced memory controller
configuration featuring 8 channels instead of 16. The driver reuses
Tegra234 memory client IDs and ICC operations, with Tegra238-specific
stream IDs for SMMU configuration.

Changes in V2:
- Reorder patches: dt-bindings patch first, driver patch second
- Resolve tegra238 build dependency on CONFIG_ARCH_TEGRA_234_SOC
- Remove lite carveouts comment from tegra238_mc_soc

Ashish Mhetre (2):
  dt-bindings: memory: tegra: Add nvidia,tegra238-mc compatible
  memory: tegra: Add T238 MC support
