2011-09-06video: tegra: dc: update emc clk for multiple dcsNitin Kumbhar
When an overlay is opened or closed it updates emc clk as per pclk. However, this does not consider state of other dc for memory bandwidth consideration. This results in underflow errors when both display controllers are in use. To avoid underflow, update emc clk as per state of both dcs.

ARMv6+ architecture does not allow ioremap on system memory. lp0 is relocated using ioremap on DRAM. If lp0 vector start address is in system memory then use memblock_reserve and do not relocate. Else if it is overlapping with carveout/fb then first remove the carveout/fb using memblock_remove and then use ioremap.

Refresh rate nearness is not calculated or reset when nearest resolution changes. This patch resets the refresh rate differential measurement whenever a new nearest resolution is discovered. This fixes two error cases; first, wherein the first mode's refresh rate differential is never calculated and second, when the closest refresh rate from a previous nearest resolution is erroneously preserved. back-ported from kernel.org (cherry picked from commit 8917a5603a3e6534d6c75ed0d91077062805b111) Reviewed-on: http://git-master/r/37417 (cherry picked from commit a169b1a92dc1ed4c824569e9dc70267cb1e2eb52) Change-Id: I9757e98053a0676491dfe943f06a0c4946ef96be Signed-off-by: Sanjay Singh Rawat <srawat@nvidia.com> Reviewed-on: http://git-master/r/42390 Reviewed-by: Donghan Ryu <dryu@nvidia.com> Tested-by: Gerrit_Virtual_Submit Reviewed-by: Bharat Nihalani <bnihalani@nvidia.com>

In current implementation, the HSIC port cannot have PHY power off without re-enumeration when it is suspended. This patch will do following upon USB port suspend: * disable the USB PHY clock * disable the shared EMC clock * keep the USB core but running it at 0.95v VDD With this patch, VDD can be reduced to when the HSIC port is suspended. There is no re-enumeration when HSIC port is resumed, also it will not affect the normal LP0 suspend/resume.
