2012-10-18colibri_t20: integrate PWM LED functionalityMarcel Ziswiler
Backlight PWM now runs at 1 kHZ rather than 500kHz. Make PWM B, C, D accessible from userspace. e.g as /sys/class/leds/pwm_b. Make PWM A or C a led PWM depending on MECS_TELLURIUM.

Invert brightness value due to unified TFT interface displays (e.g. EDT ET070080DH6) inverted LEDCTRL pin behaviour (e.g. 0V brightest vs. 3.3V darkest) and use PWM frequency of 1 kHz as recommended. Add comment about PWM pin muxing. While at it do some ifdef and indentation clean-up.

2012-08-24mtd: tegra: initialize writebufsizeMarcel Ziswiler
Using UBI on tegra can give messages like: root@colibri-t20:~# ubiattach -m 0 [ 115.218710] UBI: attaching mtd0 to ubi0 [ 115.229108] UBI error: io_init: bad write buffer size 0 for 4096 min. I/O unit ubiattach: error!: cannot attach mtd0 error 22 (Invalid argument) The writebufsize concept was introduce by commit "0e4ca7e mtd: add writebufsize field to mtd_info struct" and it represents the maximum amount of data the device writes to the media at a time. This is an important parameter for UBIFS which is used during recovery and which basically defines how big a corruption caused by a power cut can be. Set writebufsize to the flash page size because it is the maximum amount of data it writes at a time.
2012-08-20usb: gadget: tegra_udc: Enable DR IRQ in udc_starttegra-l4t-r16-rcPreetham Chandru
Currently dr_controller_run() is called only during otg state change. When we unload a gadget driver, for example g_mass_storage gadget driver, dr_controller_stop() is called but when it is loaded back dr_controller_run() won't get called becasue of the if condition failure. i.e if (!udc->transceiver) { dr_controller_run(udc); } So when the gadget driver is loaded for the second time without removing the cable (i.e without otg state change), the device won't get enumerated on the host because DR IRQs are not enabled. This CL fixes the above issue.

2012-08-20usb: ehci: tegra: Fix Slab corruption errorPreetham Chandru
Give ownership of the DMA buffer back to the processor first and then free the buffer. Otherwise processor won't be able to access the dma mapped buffers and this would lead to slab corruption. When the DMA buffer is freed without a call to dma_sync_single_for_cpu(), the kernel won't be able to set the buffer as POISON FREE and when we acquire this memory back again the kernel will start printing slab corruption output as the memory is not set to POISON FREE Bug 1017884 Bug 1018161 Reviewed-on: http://git-master/r/#change,122151 Signed-off-by: Preetham Chandru R <pchandru@nvidia.com> Reviewed-on: http://git-master/r/122390 (cherry picked from commit 642d37a0eee196d0ce811dd11bb7af5ba281ee3a) Change-Id: I00d6cb185cd2314cccb56f968eb0a05288588c13 Reviewed-on: http://git-master/r/123907 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Matthew Pedro <mapedro@nvidia.com>
