2010-06-02tegra spi: Adding the support for the hw based CS.Laxman Dewangan
It is require to use the hw based CS to meet the timing requirement as: - Minimum CS setup time i.e. time from CS active to first clock. - Maximum CS hold time i.e. CS should be active after last clock. SW based CS can support the above 1 but not 2 because it dpeneds on os load and system performance. To meet the above requirements, it is require to enable the hw based CS. As spi controller support for the hw based CS for the smaller number of packet, enabling this feature. Driver use the sw based CS by default. If client want to use the hw based CS, then it need to enable this through nvodm query NvOdmQuerySpiDeviceInfo table for different CS. For this, client need to set device info as CanUseHwBasedCs = TRUE, CsSetupTimeInClock = xx CsHoldTimeInClock = xx Tested on whistler.

2010-06-02tegra sdhci: Enabling sdio cards suspend/resumeRahul Bansal
SDIO-WIFI Behavior - 1) With or without MMC_UNSAFE_RESUME setting - As "sdio_driver" in mmc stack doesn't have suspend/resume handlers so even if MMC_UNSAFE_RESUME is set, SDIO-WIFI driver's remove/probe is called for mmc suspend/resume. Thus, on suspend (LP1 or LP0) wifi is turned off and is disconnected. On resume (from LP1 or LP0), wifi is turned on and is reconnected. 2) For all cards including sdio, power to rail is cut. On suspend for sdio slot NvOdmSdioSuspend() is called. On resume for sdio slot NvOdmSdioResume() is called.

The driver is currently not implement yet NvOdmAccelSetSampleRate and NvOdmAccelGetSampleRate, updating these two routines to able to change hw sample rate via sysfs. The interrupt method is not reliable and polling method is recommended for sending the orientation changes, so updating driver to use polling method. The sw polling time is indicated how fast sw get samples and it can be optimized depends on client application. It is calculated based on hw sample rate as below: PollingTime = (1000ms * POLLING_FACTOR)/frequency. POLLING_FACTOR is currently set to 225.

(b) "Mask in Low Corner" - LP2 is entered independently of DVFS, but DVFS tick interrupt is masked only when low corner is hit (c) "Ignore Low Corner" - LP2 is entered and DVFS tick interrupt is masked independently of DVFS low corner.

Adding apis for following function to hooking up tegra serial driver with bluesleep power management: - Clock off. - Clock on. - Setting flow control to desired state. - Checking for tx fifo status. Following 4 state machine is developed to achieve this: UART_CLOSED, UART_OPENED, UART_SUSPEND, UART_CLOCK_OFF. The transitions of state machines are as follows: UART_CLOSED: the init state on which resource is allocated but not opened by client or device is closed. UART_OPENED: Able to do data transfer. CLOSED to OPENED by opening the port. CLOCK_OFF to OPENED by calling function tegra_uart_request_clock_on(). SUSPEND to OPENED by calling resume(). UART_CLOCK_OFF: The controller clock is disabled and so no data transfer can happen. At this state, controller is not ready for deep power down. OPENED to CLOCK_OFF by calling tegra_uart_request_clock_off(). Can not go to this state from CLOSED and SUSPEND. UART_SUSPEND: The controller is in suspended state and ready for deep power down. UART_CLOCK_OFF to SUSPEND: OPENED to SUSPEND. Tested in whistler.

2010-05-20tegra-l2x0: atomic cache shutdownJitendra Lanka
Sometimes during the cache shutdown process, USB interrupts causing cache maintainance ops are leading to system crash. To avoid this, we disable interrupts before cache shutdown and enable them afterwards.

2010-05-20tegra timers: Added safety net for SMP tick handover.Alex Frid
Made sure that jiffies update duty is not stuck with off-line CPU: if this situation is detected, re-assign the tick ownership respectively (should fix bug 683277). Replaced spin-locks in timer access code with local interrupt control: local timers are "local", and do not need interprocessor protection.

2010-05-20nvmap: fix unpin/pin race condition with RECLAIM_UNPINNED_VMAntti Hatala
_nvmap_handle_unpin needs to acquire the mru_vma_lock before decrementing the pin count, to ensure that a decrement to zero and insertion on the MRU VMA list appears atomic with respect to a second client calling _nvmap_handle_pin on the same handle; otherwise, the two clients race and the pin operation may trigger a BUG because the handle has a valid IOVMM area but is not located on any MRU VMA list. also, clean up some additional allocation-inside-spinlock issues; release the MRU VMA lock before calling tegra_iovmm_create_vm, and reacquire the lock after returning.

2010-05-19tegra usb-phy: Fix UTMI/ULPI LP0 issues.Venkat Moganty
UTMIP pads were turned off before the UTMI phy is set in to the suspend mode. This is corrected by turning off the UTMIP power control pads after phy is suspended. Added workaround for ULPI to bring out of suspend by setting USB2_CLK_OVR_ON bit in CLK_RST_CONTROLLER register. Bug 679959 Tested on Ap20/Harmony with Lp0 suspend/resume tests.
