2010-01-20tegra: DMA driver and tegra serial driver updates.Venkata(Muni) Anda
DMA changes: - Channel lock should be taken in the ISR for making the DMA driver SMP safe. - In continous DMA mode,WCOUNT is the count of the half buffer not the full buffer. So, when updating the bytes received member of the req structure, received count should be accounted for appropriately. - Implemented the tegra_dma_flush() API. This API stops the DMA, resets the transfer status of the req in the head of the queue and reloads the req into the hardware if pending. - Added "threshold" callback. This is called when the buffer reaches the threshold. This is now aviable only for continous mode. Serial driver updates: - Simplifed the ISR handling in case of the DMA mode. - Using RTS to enable the flow control when dequeing and enqueing the DMA buffers. This will make sure that the sender will be flow controlled. This is still not working properly. - Added flush buffer call back - Called by serial core when the tx buffer is reset. - Fixed the locking at a couple of places, like ISR and shutdown callback. With these changes, i could able to use the BT sometimes. Sometimes i got parity errors. When I swtiched the Tx to PIO mode, BT worked fine. This can be done by changing the tx_force_pio global variable to 1. Change-Id: I4f738faac2fdb14622257878ef08db5397eebf8a

* changes: tegra nvos: return interrupted semaphores to user-land
2010-01-18tegra nvos: return interrupted semaphores to user-landGary King
split the nvos interrupt implementation into 2 parts: one which returns an error code when the thread is awakened due to a pending signal, and one which loops in the kernel until the semaphore operation completes. the user-land stub needs to immediately return control to the application in the event of a pending signal, to ensure that the signal is dealt with before re-attempting to wait on the semaphore. bug: 642544 Change-Id: I0b233c9483d67cc6d25285d0dc3eddafa8502500

2010-01-14tegra RM: add nvmem= command-line parsing for carveout aperture(s)Gary King
the bootloader may place carveout in a location that is not exactly at the top of physical memory (if, for example, the bootloader does not support mapping all the way to the top of memory), and the existing code in the RM initialization did not allow for this (or for multiple carveout apertures). add a new command-line parameter (nvmem=) to position the carveout aperture arbitrarily in the physical address space.

2010-01-13tegra RM: Fix PWM scaling calculation in RM for backlight intensity.Nagesh Penumarty
Fixed PWM scaling calculation and added boundary check. This is an 8-bit value that was being scaled to a max of 256 instead of 255, causing an overflow in the boundary case of a maximum setting (thereby resulting in 0).

2010-01-12Tegra: Pcie driver update.Venkata(Muni) Anda
-Assign IO resources starting from 0x16 instead of 0. This is needed becase the linux driver is assuming that "start" value of 0 is an allocated resource. -Added asserts to catch config access other than byte/word/dword. -Configuring interrupt as INTA to all the PCI devices.
