2011-08-15nvhost: Move include files to kernel/includeTerje Bergstrom
To prepare for kernel modularization, nvhost include files need to be moved from mach-tegra/include to kernel/include. At the same time user space specific part is split into nvhost_ioctl.h.

- The issue is due to the corruption of bootloader fb during kernel initialization. This change reserves the bootloader fb and then frees it until bootloader fb is copied to fb for Cardhu, Ventana, Whistler, Enterprise and Aruba. - Change color depth of Cardhu and Harmony to 32-bit.

2011-03-22ARM: tegra: ventana: Fixed backlight toggling.Gaurav Sarode
Ventana has both an internal panel (on fb0) and external HDMI (on fb1). One of the devices might be blanked while another is unblanked. In order for the backlight blanking logic to know whether to turn off the backlight for a particular framebuffer's blanking notification, it needs to be able to check if a given framebuffer device corresponds to the backlight. This implement the check_fb pwm_backlight hook to make the internal panel's backlight only toggle on fb0 blank changes.

2011-02-14[Ventana] hdmi hotplug - leave ventana_hdmi_enb to be 1 alwaysChong Zhang
It seems the "ventana_hdmi_enb" has to stay 1 for hotplug_gpio to work. Setting ventana_hdmi_enb to 0 in ventana_hdmi_disable() will render hotplug_gpio non-functional afterwards. Removing the gpio_set_value(ventana_hdmi_ena..) calls from both ventana_hdmi_enable() and ventana_hdmi_disable() seems to solve the problem. This leave ventana_hdmi_ena at its default value. bug 784597 Change-Id: I3c3d6282e8f17cce1287410dac7d28744cb9f8ba Reviewed-on: http://git-master/r/17083 Reviewed-by: Varun Colbert <vcolbert@nvidia.com> Tested-by: Varun Colbert <vcolbert@nvidia.com>
2011-01-31[mach-tegra/ventana] use tegra_reserve() to handle carveout memory allocationPeter Zu
For K36, the kernel command line will pass "mem=size@base" from bootloader to kernel. Apparently, we were having two different ways to interpret it 1) size = total physical memory size - carveout size 2) Or size = total physical memory size Ventana is the only platform to use #1. Switch it to #2 which requires tegra_reserve() to handle carveout memory allocation. Change carveout size to 256MB as well.
