Subject[PATCH v4 0/7] tegra20-emc: Identify memory chip by LPDDR configuration
Date
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.
