Subject: [PATCH v1 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.

Svyatoslav Ryhel (9):
  ARM: tegra: Add ACTMON support on Tegra114
  dt-bindings: memory: Document Tegra114 Memory Controller
  drivers: memory: tegra: implement EMEM regs and ICC ops for T114
  dt-bindings: memory: tegra114: Add memory client IDs
  clk: tegra114: remove emc to mc clock mux
  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
