2014-03-28arm: tegra12: Derating supportIshwarya Balaji Gururajan
Add support for derating via keeping two separate sets of EMC tables. One set is nominal, the other set is derated. Based on the temperature reported by the DRAM the EMC thermal driver can specify which set of tables the EMC driver should use when swapping frequencies. This patch also adds support for a more graduated response to rising temperature. The DRAM reports 3 levels of refresh and derating requirements: 0x4: Refresh x2 0x5: Refresh x4 0x6: Refresh x4 + derating The particular combination of refresh modification and derating is now picked based on the particular level of throttling necessary. Also, this adds the ability to control certain DRAM timing parameters like refresh rate based on over temp status and ddd ISO efficiency table for POP package Bug 1436864 Reviewed-on: http://git-master/r/#/c/377913/ Change-Id: Ibfa5820436459029f6a0f8c0980b5ad3297d5ec7 Signed-off-by: Ishwarya Balaji Gururajan <igururajan@nvidia.com> Reviewed-on: http://git-master/r/375058 Reviewed-by: Thomas Cherry <tcherry@nvidia.com> Tested-by: Thomas Cherry <tcherry@nvidia.com>
