2013-05-04ENGR00261060 mx6sl evk: make two BT modules configurable dynamicallyRobby Cai
In current implementation, the SXSDMAN BT module (on UART3) is enabled by default. This is done by hard-coded in board file, which means if we need enable the other BT module AR3001 (on UART1), we need to modify the codes and recompile the kernel. This is not good. In this patch, we enhance it by passing parameters via cmdline. Signed-off-by: Robby Cai <R63905@freescale.com>
2013-05-03ENGR00261037-2: usb: fix the bug that mark lowpower flag wronglyPeter Chen

2013-05-03ENGR00261037-1: usb: usb host works abnormal after unload gadget modulePeter Chen
If there is usb device on the OTG port when controller works at host mode, and at this time, we unload gadget module, the usbcmd.rs will be cleared, it is unexpected behavior. When the controller works at one mode(eg, host mode), the register should not be written by other mode driver (eg, devcie driver). The OTG driver does not consider this situation, and current i.mx FSL OTG driver does not support fully OTG function, so we remove the caller at fsl_otg_set_peripheral which will touch controller register.

2013-04-24ENGR00260082 mx6sl_evk: Change wm8962's MCLK to 24MHzNicolin Chen
The clock, output from wm8962's FLL, is sometimes inaccurate. This's because 26MHz is not quite stable for wm8962's internal FLL, So change to 24MHz, the value recommended by Wolfson, which has been used on SabreSD for quite a long time.

2013-04-24ENGR00258491-2 msl-mx6: usb: put PHY to be out of low power explicitlyPeter Chen
We have wrong understanding that reset controller will put PHY to be out of low power automatically, but in fact, it is not. So, we should put PHY to be out of low power explicitly if the portsc.phcd = 1 before we need to access controller's register. Some register writing will hang system (eg,PERIODICLISTBASE), some reading will not get the correct value (eg, otgsc). Signed-off-by: Peter Chen <peter.chen@freescale.com>
2013-04-24ENGR00258491-1 usb: host: fix error at unload module pathPeter Chen

2013-04-17ENGR00259189 thermal:mx6: Make sure thermal alarm working safelyAnson Huang
The thermal sensor's value will be updated even it is power down, as thermal sensor's clock source is from PLL3, so there is chance that PLL3 is disabled before thermal driver is probed during kernel boot up, so the value in thermal sensor can be incorrect in this PLL3 disabled window. Previous flow of thermal driver probe routine will enable PLL3 clock, then set the thermal alarm value and enable the alarm irq, there is no delay or check about the thermal sensor's value, only when the thermal sensor's value is correct, its alarm function can be enabled. As adding delay in the probe routine is not a good option, so we move the enabling of thermal alarm function into the get temperature routine, as after the thermal value is read, the alarm function is safe enough, as the thermal sensor will be always working right after a read if its clock is enabled.

2013-04-11ENGR00257130-6 mx6-msl: usb: Add 500us delay for phy stable timePeter Chen

2013-03-13ENGR00253927 IPU: Fix NULL pointer bug when BG EOF interrupt occur earlyWayne Zou
Fix NULL pointer bug when IPU BG EOF interrupt occur before register irq handler It can be reproduced on MIPI DSI display on i.mx6dl SabreSD board. The sequence is: a) enable display channel b) pan display (fb_set_var()) -> ipu_enable_irq c) ipu_request_irq If an EOF interrupt comes before c and after b, the issue happens.

2013-03-13ENGR00243315-5 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 introduced an annoying kernel log by changing a pure debug info to error level. This patch reverts that change. Signed-off-by: Liu Ying <Ying.Liu@freescale.com>
2013-03-13ENGR00243315-3 MXC V4L2 Capture:Remove unnecessary mclk settingLiu Ying
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. This patch removes the unnecessary mclk setting for csi_param.mclk variable, since it is only valid for CSI test mode. Signed-off-by: Liu Ying <Ying.Liu@freescale.com>

This patch removes test mode clock setting in function ipu_csi_init_interface(), since the setting is only necessary for function _ipu_csi_set_test_generator(). This unnecessary setting is added wrongly by commit f8e1a3bb62eecf93a31a51c4dbe08a0214fa1d57. Signed-off-by: Liu Ying <Ying.Liu@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.
