Hi,
The basics of Tegra SMMU has been same over generations except that
each SoC has its own combination of HardWare Accelerators(HWA). This
combination is presented by swgroup ID. This difference is handled by
the previous "Unifying SMMU driver among Tegra SoCs" patch
series[1]. For the new Tegra SoC 124 SMMU has been slightly
enhanced. To support this minor changes, Tegra SMMU platfrom data is
introduced. This data set can be choosen by DT ".comptibility"
flag. If the further tegra SoC need to tweak those parameters, we can
think of moving some of them into DT bindings eventually.
This series depend on v6 of:
"[PATCHv6 00/13] Unifying SMMU driver among Tegra SoCs"[1]
A whole patches is available in the git repository at:
