Re: [PATCH v2 0/5] Tegra20 External Memory Controller driver

Hello,

Couple years ago the Tegra20 EMC driver was removed from the kernel
due to incompatible changes in the Tegra's clock driver. This patchset
introduces a modernized EMC driver. Currently the sole purpose of the
driver is to initialize DRAM frequency to maximum rate during of the
kernels boot-up. Later we may consider implementing dynamic memory
frequency scaling, utilizing functionality provided by this driver.

Changelog:

v2:
	- Minor code cleanups like consistent use of writel_relaxed instead
	  of non-relaxed version, reworded error messages, etc.

	- Factored out use_pllm_ud bit checking into a standalone patch for
	  consistency.

  dt: bindings: tegra20-emc: Document interrupt property
  ARM: dts: tegra20: Add interrupt to External Memory Controller
  clk: tegra20: Turn EMC clock gate into divider
  clk: tegra20: Check whether direct PLLM sourcing is turned off for EMC
  memory: tegra: Introduce Tegra20 EMC driver
