2010-12-14ENGR00136921 FEC: Fix nfs not works after kernel suspend and resume on i.MX28Zeng Zhaoming
Fec phy state changing occurs in delay works, which in normal task context. And package sending mostly happens in softirq context, only happens in ksoftirq while network traffic is heavy and some _many retries_ situation. Linux network qdisc code keep raising NET_TX_SOFTIRQ softirq if package not send out when netdev queue set to start. And the subsequenece process will loop in softirq context for 10ms. Since Imx28 HZ set to 100Hz, the next timer interrupt will trigger softirq again. this loop prevent network link changing to up status. And cause a chicken-egg problem. To break this loop, we need to set netdev transmit queue stop when link is down, and start it when link becomes up. commit 757bfe446bab7661d12a8772ca10b7a490c8aa47 try to resolve this problem, but hand-merge mistake introduce a power resume bug.

2010-12-11ENGR00136223 MX50 Fix epdc display issue via PAN_DISPLAY after resumeRobby Cai
Problem ======== In suspend/resume cycle, info->var.xoffset and info->var.yoffset will be reset to 0 (in function fbcon_switch). After reume, if the xoffset/yoffset of update region happens to be 0/0, this region will not be displayed. Resolution ========== Should not compare new offset with previous offset, but compare new panning/offset state with previous state in pan_display function to determine whether need to update fb_offset.

2010-12-07ENGR00135975 usb: Add protection for resume routine for udc driverPeter Chen
At usb otg mode, the fsl_udc_resume will be called at otg_set_host and otg_set_peripheral. So we needs to add mutex_lock for fsl_udc_resume to protect being called at the same time. Besides, the fsl_udc_resume should not be called continuous twice, or the udc->suspended will be wrong Signed-off-by: Peter Chen <peter.chen@freescale.com>
2010-12-06ENGR00134285 LDB:Correct the way to match registered fb infoLiu Ying
In the probe function of LDB framebuffer driver, we will try to match the LVDS video modes defined in the driver. For LDB separate mode, we need to find two video modes matched, whereas, for other LDB modes, we need to find only one video mode matched. Signed-off-by: Liu Ying <b17645@freescale.com>
2010-12-03ENGR00133793 - EPDC fb: Use a default temp index of 0Danny Nold
- Current default temp index is 8, which causes issues for panels with only 1 temperature index. So if no temp index is found to match the temperature, use a default of 0 to ensure that a valid index is used for these special waveform types. - Firmware loading changed from blocking to non-blocking to allow EPDC driver to boot without waiting.

2010-11-24ENGR00133954-2 ipuv3: remove FB_SYNC_EXT flagJason Chen
FB_SYNC_EXT was used to represent ext clk, but actually, it represent ext sync. Some applications do not recognize it, during fb_set_var ioctl may miss it, which will cause fb display fail, for example X window startup. Remove FB_SYNC_EXT flag, and choose ext clk support by ipu driver. If you want to use ipu internal clk only, you can add int_clk to your video option like below: video=mxcdi0fb:RGB565,800x480M@55,int_clk Signed-off-by: Jason Chen <b02280@freescale.com>
