2012-04-24media: video: tegra: tegra_camera: re-arch power and clockJihoon Bang
There are a couple of issues found in tegra_camera. 1. clock enable/disable is controlled by user space. -> If client process crashes, there is no way to disable clock. 2. power enable/disable is associated with clock enable. -> There is no reason to relate power with clock. -> There is only one regulator for this driver. -> As same as #1, it may leave power up when client process crashes. 3. driver allows multiple clients to access. -> This is not the case for this driver. This changes addresses the problems described above.

2012-04-19Restore "ARM: tegra: power: Workaround PMD corruption by cpu_resume_mmu"Sang-Hun Lee
This restores commit 607d5ec8bb46f95473533f611da1ffc97907d16e. The common ARM CPU state suspend/resume code does not work with and external L2 cache controller (like a PL310) enabled. This change fixes corruption of the current PMD by the MMU resume code. cpu_resume_mmu modifies the currently active page tables to add a flat (VA==PA) section mapping of cpu_resume_turn_mmu_on to handle MMU off-to-on transition. It turns off the L1 data cache but it knows nothing of the L2 cache. Since page table walks are L2 cacheable, other CPUs in the system can pick up the corrupted PMD which will eventually result in a kernel panic. The workaround for this is to modify push_ctx_regs to save the current TTB0 and CONTEXID registers in the CPU register context and switch to the private tegra_pgd before saving the rest of the CPU context. The tegra_pgd already has a flat mapping for the code in question, so it can't be damaged by the actions of cpu_resume_mmu. Likewise, pop_ctx_regs is modified to restore the actual TTB0 and CONTEXTID registers when restoring the CPU registers.

2012-04-18arm: tegra: enterprise: disable dsi_csi_rail in LP0Vinayak Pane
AVDD_DSI_CSI is shared by modem and dsi. If DSI turns off this rail then HSIC fails after wakeup from modem. This patch provides a way to turn on this rail from modem as well as from DSI. Create two virtual power rails from avdd_csi_dsi to control it from both the drivers separately. This is enterprise specific change as per the power rail layout.
