Support memory chip identification by LPDDR2 configuration, which is
needed by ASUS Transformer TF101 tablet device that doesn't store RAMCODE
in Tegra's NVMEM.
Changelog:
v4: - Moved DDR bindings directory to memory-controllers/, like it
was suggested by Krzysztof Kozlowski.
- Converted existing LPDDR2 binding to schema and utilized it,
like it was requested by Krzysztof Kozlowski.
- Added Elpida B8132B2PB-6D-F compatible.
- Made code changes that were requested by Krzysztof Kozlowski.
v3: - Corrected sub-node name in tegra20-emc.yaml.
v2: - Added separate binding for standard LPDDR2 properties, like it
was suggested by Krzysztof Kozlowski.
- Switched Tegra binding to use new lpddr2-configuration sub-node
that contains the standard properties.
- Extended commit message of the "emc: Document new LPDDR2 sub-node"
patch, telling how the properties are supposed to be used, which
was requested by Krzysztof Kozlowski.
- Added new common helpers for parsing LPDDR2 properties and made
tegra20-emc driver to use these helpers.
