From: Joseph Lo <josephl@xxxxxxxxxx>
This is the initial patch for Tegra210 EMC frequency scaling. It has the
code to program various aspects of the EMC that are standardized, but it
does not yet include the specific programming sequence needed for clock
scaling.
The driver is designed to support LPDDR4 SDRAM. Devices that use LPDDR4
need to perform training of the RAM before it can be used. Firmware will
perform this training during early boot and pass a table of supported
frequencies to the kernel via device tree.
For the frequencies above 800 MHz, periodic retraining is needed to
compensate for changes in timing. This periodic training will have to be
performed until the frequency drops back to or below 800 MHz.
This driver provides helpers used during this runtime retraining that
will be used by the sequence specific code in a follow-up patch.
Based on work by Peter De Schrijver <pdeschrijver@xxxxxxxxxx>.

Changes in v6:
- use __maybe_unused instead of #ifdef'ery for suspend/resume callbacks
- take exclusive control of EMC clock during suspend/resume
- move EMC driver changes from clk patch to this patch
- make the driver buildable as a module
- remove unnecessary suspend tracking
- remove duplicate register defines
- add tegra210-emc.h for Tegra210-specific registers
- detect number of channels, number of devices and DRAM type at probe
time and store them in struct tegra210_emc, remove the corresponding
function parameters where no longer needed
- properly clean up on failure
Changes in v5:
- major rework and cleanup

+ * It contains the following files:
+ *
+ * - available_rates: This file contains a list of valid, space-separated
+ * EMC frequencies.
+ *
+ * - min_rate: Writing a value to this file sets the given frequency as the
+ * floor of the permitted range. If this is higher than the currently
+ * configured EMC frequency, this will cause the frequency to be
+ * increased so that it stays within the valid range.
+ *
+ * - max_rate: Similarily to the min_rate file, writing a value to this file
+ * sets the given frequency as the ceiling of the permitted range. If
+ * the value is lower than the currently configured EMC frequency, this
+ * will cause the frequency to be decreased so that it stays within the
