Subject: [PATCH v2 0/9] Tegra114: implement EMC support

Add support for External Memory Controller found in Tegra 4 SoC along
with adjustments required for it to work properly.

Tested on ASUS TF701T (T40X) and Nvidia Tegratab (T40S). Both work fine.

This patchset requires DFLL patches to be applied first to avoid
issues https://patchwork.ozlabs.org/project/linux-tegra/list/?series=464976

Changes in v2:
- fix programming completion detection (changed EMC reg to MC reg reading)
- Tegra114 incorporated into Tegra124 dt-bindings schema
---

Svyatoslav Ryhel (9):
  ARM: tegra: Add ACTMON support on Tegra114
  dt-bindings: memory: Document Tegra114 Memory Controller
  memory: tegra: implement EMEM regs and ICC ops for Tegra114
  dt-bindings: memory: Add Tegra114 memory client IDs
  clk: tegra: remove EMC to MC clock mux in Tegra114
  dt-bindings: memory: Document Tegra114 External Memory Controller
  memory: tegra: Add Tegra114 EMC driver
  ARM: tegra: Add External Memory Controller node on Tegra114
  ARM: tegra: Add EMC OPP and ICC properties to Tegra114 EMC and ACTMON
    device-tree nodes
