Changelog:
v5:
- Fixed wrong EMC clock divider type in the "Turn EMC clock gate into
divider" patch. It is a Tegra's fractional 7.1 divider and not a
simple integer divider. Peter, please take a look at the change.
v4:
- Fixed "bad of_node_put()" error which was revealed by enabling
some extra kernel debug config options.
- The "emc-table" DT nodes are now parsed starting from the "emc"
node instead of the DT root.
- Adjusted code comment in the "Turn EMC clock gate into divider"
patch as was suggested by Stephen Boyd to the v3.
v3:
- Handle "nvidia,use-ram-code" DT property, its handling was missed
in the previous versions.
- Honor "emc-tables" DT node naming which is explicitly specified
in the DT binding, also was missed in the previous versions.
- Two new DT binding patches: one adds the EMC clock property,
other relocates the binding doc file to the appropriate directory.
One new patch that adds EMC clock property to the DTS file.
- Addressed v2 review comments from Thierry Reding. Driver does not
preserve backwards compatibility with older device tree binding.
- The PLL_M and PLL_P clocks are kept internal to the driver because
after some more considering I couldn't find a really good reason why
these clocks should be in the device tree.
- Some minor cleanups and fixes in the drivers code.
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.
