* changes: tegra: power management for mouse/keyboard drivers
2010-01-21tegra: Update the UART Tx data path and added new system DMA API.Venkata(Muni) Anda
-Using workqueues instead of tasklets for Tx DMA. -Waiting for the FIFO to drain after the DMA is done, as it is apparently needed by the HW. - Added new DMA API to check if the req is already queued. Using tegra_dma_is_empty might not be correct as one DMA chanel can be serviced by multiple clients. With this change, i can browse the BT sometimes. It takes some retires to enable the BT. Also during the operation of the BT, i still see the messages like "out-of-order packet arrived" Don't know if this is an issue with ther UART or the BT protocol.

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
2010-01-20tegra: Dynamically control the card clock for SD memory devicesDeepesh Gujarathi
On certain embedded devices, leaving the card clock enabled on SD memory devices with no active transactions can increase power consumption. Enable this option to automatically disable the card clock after a transfer completes. Change-Id: I6da3388c1528bf1334c3534b7251a526812199f1
2010-01-19tegra usb: fix build break when OTG not configuredGary King
commit 98968646e2f ("Adding USB OTG feature") causes the build to break due to dependencies on otg_get_transceiver if OTG isn't enabled for the platform. Change-Id: I97af1bb032297f922932a30fa4ef7e4607133592

* changes: tegra usb host: stubbing out ehci_bus suspend/resume
2010-01-13tegra usb host: stubbing out ehci_bus suspend/resumeMayuresh Kulkarni
This is needed as ehci_bus_suspend() gets called during bootup which causes the boot process to hang when tegra suspend ops is registered with kernel. Change-Id: Ic6976ee8c04e284d3fb89a8f69cb662f5dbeffa6
2010-01-12tegra HS UART driver: Use PIO when DMA is not available.Venkata(Muni) Anda

2010-01-12tegra spi: Removing the unused api for multipletransferLaxman Dewangan
Removing the api NvRmSpiOptimizedMultipleTransactions() which was added for the experiment to root casue the high cpu consumption. It is found that BusyHint() was taking the higher cpu time. The issue has been already fixed and now this api should be removed. Tested with harmony boot and compilation. Change-Id: I1eda05f22d66a2bd78d837911be6d269f56937b5

2010-01-08serial: compile fixes for tegra native serial driverGary King
when the serial driver was merged to git from perforce, some errors were introduced during the reformatting of it. these are now fixed. add a Kconfig to specify the maximum number of high-speed UARTs supported by the kernel, which will be used to ensure that enough DMA channels are reserved from the Tegra RM to allow the driver initialization to succeed Change-Id: I363a8375ebbdda004161672ff3700eb09be474ae

2009-12-21mmc: don't bug when EMBEDDED_MMC_START_OFFSET > CSD capacityGary King
for sector-addressed cards, the CSD capacity will generally be a small number, and this will often be less than the byte offset of the EMBEDDED_MMC_START_OFFSET. bugging in this case is wrong.

removes some unnecessary status prints in tegra_udc.c and sdhci-tegra.c fixes the type in the tegra driver name in fsl_udc_core.c
2009-12-21ehci: enable clocks on tegra during shutdownGary King
tegra dynamically clocks access to the controller, so if no peripherals are attached the controller clocks will be disabled to conserve power since shutdown accesses the controller registers, the controller must have its clocks enabled, regardless of the presence of peripherals Change-Id: Ia95859fda514001cb8ad58260c3e58b4f470080c
