In this commit 957bc47ffbad8532f0e8f6463946e8c04bc3176f, add msleep(400) for reducing noise in the hw_params, but this time is very long for opening device. In this patch, remove this time and use the "Soft Ramp on Zero Crossings" to reduce the noise. Signed-off-by: b02247 <b02247@freescale.com>
2013-03-29ENGR00255406 net: fec: Workaround tx hang due to TDAR bit cleared by uDMAFugang Duan
MTIP enet IP have one IC issue recorded at PDM ticket:TKT168103 The issue description: The TDAR bit after being set by software is not acted upon by the ENET module due to the timing of when the ENET state machine clearing the TDAR bit occurring coincident or momentarily after the software sets the bit. The result: The corresponding transmit packet for an incoming ping is delayed. Workaround: This forces the ENET module to check the Transmit buffer descriptor and take action if the “ready” flag is set. Otherwise the ENET module returns to idle mode.

2013-03-27ENGR00255111 battery: fix voltage decreased only while dischargingRobin Gong
If system run higher cpu loading with bigger current, such as GPU or VPU, the voltage of battery will decrease down quickly and rise up later.But the battery driver only permit voltage decreasing while discharging before, in other words, in the above case , the voltage will keep in very low level, although the voltage will rise back again. Now, remove the constrain in the code. Of course, with the patch, voltage will down and rise back when run high loading user case, but it's better than LOW ALWAYS, in worst case, the battery capacity will be 0 as test team reported Please note : Current battery capaity is not accurate because of hardware design defect(ENGR00219632) on Sabresd.So please ignore the accuracy issue.

2013-03-22ENGR00255482 ASoC: HDMI-audio: Add error message for HDMI-video detect failureNicolin Chen
HDMI-audio depends on HDMI-video. If users want to use HDMI-audio function, they need to load HDMI-video first. Sometime users would forget to put video info into U-boot cmdline, "video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24" for example. That might cause HDMI-auido driver fail to detect HDMI-video. Previously, if this happened to system, driver only returned with "ENOMEM" and system would print "Can't allocate memory". This might confuse users due to the vague infomation. Users would be hard to figure out the root cause. So this patch just add some error message to give users a clear indication, and changed the "ENOMEM" error number to the more precise "ENODEV".

The issue happens when the rootfs application Xfbdev calls fb_set_var() for IPU BG fb to unblank the console, so it wants to reinitialize the IPU BG.

2013-03-14ENGR00243315-5 ADV7180:Power management adjustmentLiu Ying
ADV7180 power down/on can be controlled by a gpio pin or i2c register setting. The PDBP bit in 0x0f register chooses the control source, and the PWRDWN bit in 0x0f register chooses to power down the chip or power on the chip if control source is i2c. This patch removes all gpio pin power down/on code after probe function and uses i2c to do power down/on operation, as some boards may choose to not connect ADV7180 power down pin with AP, however, AP's i2c bus has to be connect with the ADV7180 chip. Moveover, this patch also adds a 400ms sleep after the chip is powered on, which is a workaround for preview scrolling issue(we suspect that the chip needs some time to in a stable status, so that it may sends correct data to AP).

commit f8e1a3bb62eecf93a31a51c4dbe08a0214fa1d57 added a hard coding for csi_parma.mclk setting to 27MHz. The comment added by that commit is totally wrong by telling that csi_param.mclk would be a kind of 'pixel clock' set in 'csi_data_dest' register.

2013-03-12ENGR00252411: mxc_v4l2_capture: ov5642/ov5640 cannot both be set as build-in.Sheng Nan
ov5642 and ov5640 are inside choice "prompt "Select Camera/TV Decoder"" It prevents some modules are set as build-in at the same time. All the cameras inside the choice are parallel cameras. There is no need to include all of them inside a choice. Know issues: ADV7180 (out of the choice) and mipi ov camera (inside the choice) can not be both selected for ARM2 board: CSI0_MCLK pad is conflicted between adv7180 and mipi camera ext port. Developers should know this. Signed-off-by: Sheng Nan <b38800@freescale.com>

Both ov5642 and ov5640 need to be supported for parallel port of validation board and no code change is needed when change from one sensor to another. - Add additional common i2c id for ov5640 and ov5642 for auto dectection - Since two sensors will be checked because of auto detection, so use warning instead of error if sensor id don't match. - Add found information to tell user which camera is found.

Because ov5642 and ov5640 changes the probe information due to auto detect, ov5640_mipi should keep the same. - Add found information to tell user ov5640_mipi is found. - Use the same "not found" information as ov5642/ov5640. Signed-off-by: Sheng Nan <b38800@freescale.com>

2013-03-12ENGR00234501 ASoC: spdif: fix Ubuntu reboot hang issueNicolin Chen
spdif driver registered kcontrol for ALSA subsystem controlling, while some of those kcontrol functions lack of clk_enable() before register-accessing. So system would definitely hang when those functions're called, which did happen during reboot test on Ubuntu due to its pulse-audio. This patch added paired clk_en/disable() to those functions so as to pevent system hang issue.

If DAC volume's set to a value that's lower than 0xd8, contineously FLL setting of wm8962 in machine driver would cause playback distortion issue, which happens to ENGR219882. so we have to put some another code in machine driver to prevent distortion issue.

2013-03-12ENGR00253290-1 ASoC: wm8962: fix over-gained audio playback issueNicolin Chen
We put some code to set default volumes in codec driver, but later we found that one of volume was higher than 0db, which would cause over-gained volume. So this patch removed DAC default volume setting, and reverted the volume interface of it to let user control the register from user space.

2013-03-06ARM: 7417/1: vfp: ensure preemption is disabled when enabling VFP accessWill Deacon
The vfp_enable function enables access to the VFP co-processor register space (cp10 and cp11) on the current CPU and must be called with preemption disabled. Unfortunately, the vfp_init late initcall does not disable preemption and can lead to an oops during boot if thread migration occurs at the wrong time and we end up attempting to access the FPSID on a CPU with VFP access disabled. This patch fixes the initcall to call vfp_enable from a non-preemptible context on each CPU and adds a BUG_ON(preemptible) to ensure that any similar problems are easily spotted in the future.

Keep the phy lower flag as true defaultly, the driver should mark it as false when the driver begins to use PHY. This fixes one bug that when build both host and gadget as loadable modules, the phy lower flag is false if the related module is not loaded, then, the wakeup interrupt will not be treated as happened if host module is loaded, but gadget is not loaded, or vice verse.
