2010-02-22keyboard: remove suspend/resume calls from tegra nvec driverGary King
occassionally, the keyboard stops functioning after the system resumes from suspend state; this may be due to a failure enabling keyboard scanning mode during suspend. disable suspend/resume calls from nvec keyboard driver until a solution for this problem is resolved (e.g., converting nvec to a bus).

2010-02-17tegra usb:Fix suspend/resume failure in OTG mode.Venkat Moganty
In OTG mode during suspend/resume functionalities both device driver and host driver are accessing the USB1 controller registers with out checking the operation mode. Host driver is reading wrong status values from the registers causing the stack dump. This is fixed by checking the OTG state and guarding the hardware to access by only one driver(host or device), which is currently in operation. Bug 651253 : [Whistler] : USB gadget and/or EHCI bus suspend/resume API causes crash 1st after suspend/resume Tested on : Android/whistler with suspend/resume framework enabled. Suspend/resume sequence work fine with OTG enabled.

Using delayed suspend prevents the system from going into suspend. The delayed suspend work queue acquires a wakelock and the power manager kicks in before the delayed suspend gets scheduled.

2010-02-12f_mass_storage: allow platform to set bulk buffer sizeGary King
add a field to the android_usb_platform_data structure to allow platforms to specify the size of the bulk transfer buffer; if unspecified, default to the BULK_BUFFER_SIZE defined by f_mass_storage.c (previously defined as 4KiB). on harmony (tegra 2), performance of a class 10 SD card mounted as USB mass storage through this gadget has been measured to increase from ~7MB/sec read to ~17MB/sec read by increasing the buffer size from 4KiB to 16KiB.

SD clock is enabled when the sdhci host is claimed and clk is disabled when host is released. Use delayed suspend for better performance. Change-Id: Ied5e0f00c41abd4f6d0918405356a9983ae06552
2010-02-11tegra usbh: whistler suspend/resume failure fixBitan Biswas
With OTG disabled on whistler the suspend/resume code was hanging. The reason is because register reads hang when clocks are disabled. This fix tries to skip the suspend calls when device is already in suspend state. This avoids attempts to read register with clocks disabled. Bug 651253 : [Whistler] : USB gadget and/or EHCI bus suspend/resume API causes crash 1st after suspend/resume Reviewed by: vmoganty Tested on : whistler with suspend/resume framework enabled. Suspend/resume sequence seems to work fine on whistler and harmony with OTG disabled in kernel and odm_query. Change-Id: Iedc096648deab5c3b80350446c4ee67f625df27e

2010-02-10nvmap: change from platform device to mem deviceGary King
in order to implement user vs super-user protections for the nvmap functionality, multiple device nodes need to be created with separate file operations, similar to the mem vs kmem separation. since nvmap is conceptually similar to the other "mem" class devices, the multiple device nodes are added as new minor numbers in the mem class, and the existing platform driver registration is removed.

2010-02-11serial: Fix intermediate variable overflowAnantha Idapalapati
tegra serial driver calculates the clock values based on baudrate requested. while calculating clock values for higher baud rates, the intermediate values are getting truncated because of 32-bit overflow. Redefining the intermediate variables to 64-bit(unsigned long long instead of unsigned long) is resolving the issue.

2010-02-04tegra ec_battery : Polling for Battery and power supply infoSachin Nikam
Bug 646822 Synopsis:[Harmony/android] Battery status is not updated whenever there is any change in battery/power supply property - Created a timer of interval 30 Secs which calls the function tegra_battery_poll_timer_func(). This reports to the power supply core for power supply changes for Battery, AC and USB. Which gets the updated info from EC battery driver and signals the uvent. The JNI and Battery Info application which is waiting on this uevent then updates themselves with this lateset info from /sys/class/power_supply/* - Unregsitered to power_supply in remove function. - Added suspend-resume functions - Deleting polling timer while suspend and creating it again while resume.

2010-02-03tegra rtc: work-around Y2038 issue with uninitialized PMUsGary King
an uninitialized PMU may return a completely random value for the number of seconds; when this value is interpreted as number of seconds since 1970, this can cause severe instability if the value is >= 0x80000000UL (which is January 2038, sign-overflowing the 32b signed time_t value used in the kernel) to work-around this issue, when the RTC driver is probed, it performs an initial read of the PMU's time; if the value returned would result in a negative time_t value, the PMU RTC is reset to 0. bug 648967 Change-Id: Icee9940b5433e7e22edf98f9fcd5c7193b5c4f1f

2010-02-03tegra: Use write-combined DMA buffer for Tx DMA instead of zero-copy DMA.Venkata(Muni) Anda
Given the constraints of Tx DMA to only use the dword aligned buffer start and dword aligned size, it would prudent to allocate a uncached DMA buffer and copy the data to that buffer before the trasmit. Main reason if Flushing L2 is not a cheap operation and the UART driver model is having to do all the operations while holding the spin-lock will not work.

2010-02-02nvmap: use inner cacheable, outer non-cacheable mappingsGary King
nvmap-allocated memory is used primarily by DMA devices, and the cost of L2 maintenance generally greatly outweighs the benefit of caching the (mostly streaming) accesses. a reserved region of the kernel's virtual address space (NVMAP_BASE to NVMAP_BASE+NVMAP_SIZE) is used by nvmap as a temporary mapping area for all operations (cache maintenance, read, write) on memory handles is perfomed by mapping each page into the nvmap aperture with the same cache attributes as other active mappings. this change greatly improves the performance of drawing the drawer and web pages in Android, since the primary bottleneck in both cases has been the L2 cache maintenance operations (which no longer exist) additionally, when cache writebacks are requested on large regions (currently defined as >= 3 pages), the entire L1 data cache is flushed, to avoid the loop costs of per-line operations.
