2011-03-24ENGR00141092 usb: fix some tiny bugs for usbrel_imx_2.6.35_11.03.00Peter Chen
For android system, the gadget driver is built in, when the usb device is on otg port, the udc suspended counter will be error at the situation. This patch fix it, if this situation is met, the udc suspended counter will be not added. Using A VBus Valid to judge whether the usb cable is connected, as some boards' vbus may higher than 0.8v(B Session Valid) Signed-off-by: Peter Chen <peter.chen@freescale.com>
2011-03-23ENGR00140950 mfg: fix the bug that ubiformat utility breaks utp protocolPeter Chen
ubiformat includes command, data, command periods, it breaks utp protocol for PUT commands. So we add two operations to fix it. One is sending busy to host before the data periods begins. The second is adding a new command to waiting ubiformat's command period. Signed-off-by: Li Xingyu <b02754@freescale.com> Signed-off-by: Peter Chen <peter.chen@freescale.com>
2011-03-22ENGR00140893-1 VPU: remove VPU IRAM config and add iram info to plat data.Sammy He
One kernel image is requested, however, we need to enable iram for performance improvement on mx53, and disable it on mx51 due to known issue. So use platform data to pass vpu iram disable/enable flag. And considering requested iram size also can be different per requirement, iram size is also set in platform data.

2011-03-16ENGR00140638 - EPDC fb: System may hang if entering suspend while updates activeDanny Nold
- Added signalling to ensure suspend call does not return until EPDC has powered down. - Fixed race condition in IST. The working buffer (WB) process for a new update may report collision with LUTs that complete and are processed and removed by the IST before the working buffer completes. When this occurs, the collision may wait (forever) for a LUT that has already completed. This was putting the update queues into a bad state, preventing the update pipe from being flushed out. Solved this by tracking all completed LUTs after the WB process begins, and then removing them from the collision mask once the WB completes. Signed-off-by: Danny Nold <dannynold@freescale.com>

2011-03-15staging: add ath6kl driver for AR6003 chipVipin Mehta
AR6003 is a single stream, SDIO based 802.11 chipset from Atheros optimized for mobile and embedded devices. ath6kl is a cfg80211 driver for AR6003 and supports both the station and AP mode of operation. Station mode supports 802.11 a/b/g/n with HT20 on 2.4/5GHz and HT40 only on 5GHz. Some of the other features include WPA/WPA2, WPS, WMM, WMM-PS, and BT coexistence. AP mode can be operated only in b/g mode with support for a subset of features mentioned above. The driver supports cfg80211 but comes with its own set of wext ioctls which have historically supported some of our customers with features like BT 3.0 and AP mode of operation. For further details, please refer to: http://wireless.kernel.org/en/users/Drivers/ath6kl The driver requires firmware that runs on the chip's network processor. The majority of it is stored in ROM. The binaries that are downloaded and executed from RAM are as follows: 1) Patch against the code in ROM for bug fixes and feature enhancements. 2) Code to copy the data from the OTP region of the memory into RAM. 3) Calibration file carrying board specific data. The above files need to be present in the directory '/lib/firmware/ath6k/AR6003/hw2.0/' for the driver to initialize the chip upon enumeration. The files can be downloaded from the link specified at the following location: http://wireless.kernel.org/en/users/Drivers/ath6kl#Download This driver is only provided in the interim while we work on the mac80211 replacement, ath6k. Once the mac80211 driver achieves feature parity with the ath6kl driver, the ath6kl will be deprecated and removed from staging.

This patch adds ISL29023 light sensor support. Users may control the light sensor work at different modes/ranges/resolutions or read the lux value via sysfs. A power state node is also created in sysfs. If the light sensor works at ALS once mode, users need to power down/power up the sensor before read the lux value again.

2011-02-25fbdev: Fix fb_find_nearest_mode refresh comparisonAndrew Kephart
Refresh rate nearness is not calculated or reset when nearest resolution changes. This patch resets the refresh rate differential measurement whenever a new nearest resolution is discovered. This fixes two error cases; first, wherein the first mode's refresh rate differential is never calculated and second, when the closest refresh rate from a previous nearest resolution is erroneously preserved.

2011-02-21ENGR00139192 - EPDC fb: Refine merging and workaround missed collisionDanny Nold
Added code to detect the potential for a "missed collision", where an update would cause a collision with an update sitting on the collision list, but does not do so with currently active updates. For this case, we conservatively treat the update as if it has generated a collision. Refined merging algorithm by blocking the merge process upon detecting certain conditions where no further merges should be done. Also added check for a special case where update regions are identical. Signed-off-by: Danny Nold <dannynold@freescale.com>

2011-02-11ENGR00139076 - EPDC fb: Pan display may drop key updatesDanny Nold
Instead of dropping updates with a different panning offset than the current framebuffer panning offset, we just process those updates using the current framebuffer panning offset.
