2010-01-22tegra: Hooked pm_power_off callback to the Board adaptation.Venkata(Muni) Anda
When the systemn is powered off, pm_power_off callback is called which sets the voltage rail corresponding to the GUID NV_VDD_SoC_ODM_ID to Off. So, to use the power off feature, implement the NV_VDD_SoC_ODM_ID GUID to power rail mapping and PMU odm adaptation to turn off that rail. Change-Id: I4c439325cd14bb848f100b3e7ddc029a20cd0c9d

2010-01-21tegra: Bluetooth reset pulse width is not long enough.Venkata(Muni) Anda
Fixed 2 issues in the rfkill driver for bluetooth. - Code assumed that the GPIO is the power pin, when it is infact a reset pin Fixed by renaming the variable. - Length of the reset pulse was not long enough and didn't met the spec. Added a 5 msec sleep to meet the CSR spec. Change-Id: I592d4cd0b5addad357c38af72f5a96ed1f0e8bc3
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

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.

2010-01-15tegra2 rtc: date/time non-persistent on boardsBitan Biswas
Changes are as follows: 1) TPS6586x PMU RTC(harmony) cannot store more than 34 years duration. Hence, RTC driver has been modified to use year 2009 as reference instead of the year 1970(used in linux by default). Change in tps6586x rtc implementation. Issue was Fixed in Bug 621031 earlier and checked into p4 by modifying tegra rtc driver. We are using a different approach now by only modifying tps6586x rtc driver. This way rtc drivers for other PMU like max8907b which can store as much 9999 years in RTC do not need to change. 2) MAX8907B PMU RTC(whistler) driver was not storing day/month/year data earlier. Further, on every boot the RTC was being cleared. Fixed this in file max8907b_rtc.c Implementation specific to linux as uses library functions: mktime and rtc_time_to_tm 3) MAX8907B PMU I2C read API implementation was not reading 4th byte. Changed this as DD, MM, YY1, YY2 information is being read now. Changed max8907b_i2c.c Bug 625990 : [Firefly2/Harmony] Date & Time is not persisting after reboot Tested on : Harmony + whistler. Date/time persists. Note: Whistler rechargable battery needs to be charged to 2.4V for RTC data to persist. Harmony has non-rechargable battery. Change-Id: I07377e14c03dc7a9240190253885541be7f9a7d1
