2012-06-25arm: tegra: kai: Fix panel power on/off sequenceKen Chang
Panel power on/off sequence should meet the panel spec as below. power on: 1. EN_VDD_PNL 2. PCLK 3. LVDS_EN 4. LCD_BL_PWN power off: 1. LCD_BL_PWN 2. LVDS_EN 3. PCLK 4. EN_VDD_PNL Pixel clock on/off is controlled by dc driver, we need to separate the setting of panel enable/disable into two parts. The first, i.e., before pclk on/off, is done in kai_panel_enable()/kai_panel_prepoweroff(). And the second part, i.e., after pclk on/off, is done in kai_panel_postpoweron()/kai_panel_disable(). bug 976081 Signed-off-by: Ken Chang <kenc@nvidia.com> Reviewed-on: http://git-master/r/102555 Reviewed-by: Artiste Hsu <chhsu@nvidia.com> Reviewed-by: Prajakta Gudadhe <pgudadhe@nvidia.com> (cherry picked from commit 8149532e20729c359eb1680297f19a8f46343054) Change-Id: Ifc0d60c2caabf60f4186179e64756a4caabf9af6 Reviewed-on: http://git-master/r/110297 Tested-by: Ken Chang <kenc@nvidia.com> Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Artiste Hsu <chhsu@nvidia.com> Reviewed-by: Jon Mayo <jmayo@nvidia.com>
2012-06-19arm: tegra: Fix cpu governor change issuePuneet Saxena
It fixes the issue where cpu governor change was inconsistent across platforms. In T2x, AUTO HOTPLUG is disabled therefore we need to store/restore gov for all online cpus across LP0 cycle. In T3x, AUTO HOTPLUG is enabled therefore storing/restoring gov for Cpu0 across LP0 cycle. Cpu0 remains online in suspend and resume. bug 991081 Change-Id: I167654aa21e4832b3fdc40e3d388a4d3f984632b Signed-off-by: Puneet Saxena <puneets@nvidia.com> Reviewed-on: http://git-master/r/105404 Reviewed-by: Simone Willett <swillett@nvidia.com> Tested-by: Simone Willett <swillett@nvidia.com>

Move the device structures to the driver source code files. Register all nvhost_device's in one loop which is called from board file. host1x driver code is moved to live under host1x, too. This causes a need to add host to include path of tegradc and nvavp.

2012-03-06video: tegra: host: register nvhost master device in board-xxx-panel.cMayuresh Kulkarni
- the suspend order of devices is governed by the order in which devices are registered - this commit ensures that nvhost master is registered before any of the graphics devices - previously this was done in rootfs_init call which is later than arch_init calls of board-xxx-panel.c - this caused tegra-dc device to be registered *before* nvhost master device. as a result it was suspended *later* than nvhost master device. this is a clear violation of dependency rule for nvhost. this caused suspend-resume to fail for L4T - this worked on android as it has CONFIG early suspend enabled while it failed for L4T which doesn't have CONFIG early suspend enabled Bug 947617 Change-Id: I6cd405f3ba23d004e7659140019f5130e6c25159 Signed-off-by: Mayuresh Kulkarni <mkulkarni@nvidia.com> Reviewed-on: http://git-master/r/87756 Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>

2012-02-28video: tegra: host: Merge tegra_grhost and host1x devicesMayuresh Kulkarni
- tegra_grhost is a platform device that represents host1x - nvhost has device host1x which represents the same hardware - merge these two device structs - as the new struct is a nvhost_device, platform_driver is also converted into a nvhost_driver - register nvhost device before other graphics devices. this ensures that nvhost_probe() is called as soon as nvhost_driver is registered with the core. - this also ensures that nvmap is probed first, followed by nvhost, followed by tegra-dc and nvavp (if they are enabled).
