2012-07-10ENGR00216010-3: spdc: Make clock enable/disable paired for PIX and AXIimx-android-r13.5-alphaRobby Cai
Really disable pix/axi clock when SPDC is idle. Signed-off-by: Robby Cai <R63905@freescale.com>
2012-07-10ENGR00216010-2: [e|s]pdc: re-initialize the controller after resumeRobby Cai
Because we have DISPLAY power down/up request when do suspend/resume, EPDC/SPDC has been powered off and powered on again, thus re-initialization is needed. Signed-off-by: Robby Cai <R63905@freescale.com>
2012-07-10ENGR00216010-1: gpc: Add missing display_pup_req config after system resumesRobby Cai
There's only DISPLAY power down request setting before system suspends, but without the paired DISPLAY power up request setting after resume. This will cause ePxP/EPDC/SPDC module nonfunctional because the modules will be powered down once pdn_req is asserted but not powered up again. With this patch, ePxP/EPDC/SPDC survived (need reinitialize each, however) on resume. Signed-off-by: Robby Cai <R63905@freescale.com>

2012-07-10ENGR00215718: battery: fix issure that coulomb data increases in dischargerRong Dian
Hardware cannot support battery internal resistance and coulomb calculation, estimate data only by battery voltage.The true battery voltage will change to a bit lower about 50mV~500mV than normal voltage with playing game or video or other consumption actions, then change back to normal voltage with finishing playing game or video or other consumption actions in the discharger stage.

2012-07-10ENGR00216013-4 vpu: add phy address check ioctl.Zhang Jiejing
this patch is adding a ioctl for vpu to check the phy addr before vpu start using this addr, this use case is common in some Direct Render case, the VPU 's framebuffer phy memory is allocate by GPU, if the address given by GPU have some wrong, like pass a virtual address, vpu will hang the system. Add this IOCTL to be the goalkeeper, this IOCTL can check whether the phy address was virtual memory or the address is within phy memory of your DDR. The phy memory valild check is now doing best effort: 1. check whether is was allocated by vmalloc(), which must be a phy un-continus 2. check whether is was beyound DDR's top address, usually the other driver pass a virtual address as a phy address.

2012-07-10ENGR00216013-2 mx6: not call memblock_free after reserve memory.Zhang Jiejing
Remove call memblock_free after reserve memory with memblock_allocate(). The function of memblock_free is to remove the memory block from reserve list of memblock, it will totally lost the info about how much phy memory we have. Skipping call this can make the reserved memory be accountable in memblock With no side-effect. After doing this, we can know how much our phy memory is, then can add check in our driver like(vpu) to check the phy memory valid or not before vpu start use the address.

2012-07-10ENGR00216013-1 memblock: add memblock_end_of_DRAM_with_reserved() function.Zhang Jiejing
add a function to check the end address including reserved memory, this API can provide the top address of phy memory, it can be used to check if the phy memory is valild in some driver like VPU. Signed-off-by: Zhang Jiejing <jiejing.zhang@freescale.com>
2012-07-10ENGR00215792 USB:fix gadget issue when boot kernel with USB connectedmake shi
- USB gadget disconnected when system boot kernel with USB connected. Commit 68b1c60f7f6c436340206679a18d61d9 induce the issue, call dr_discharge_line(1) to ensure no abnormal usb wakeup interrupt happen after plug out the cable. There are two cases cause dr_discharge_line(1) of fsl_otg_event() be called. One case is switch the otg mode form Host mode to Device mode. Another case is boot kernel with USB connected. The host_first_call is true when system boot kernel with USB connected, otherwise it is false. So dr_discharge_line(true) should not be called in fsl_otg_event() if host_first_call is true. - USBOH3 clock is still on after plug out the cable when boot kernel with USB connected, If the suspended bit is 0x1 and stopped is 0x0,the case is regarded as suspend connected to usb charger. USB clock will be turn on, otherwise the second suspend is processed without USB clock and it causes system hang. But system boot kernel with cable connected, suspended is 0x1 and stopped is 0x0. USB clock will be on by mistake. And stopped is cleared in dr_controller_run() when system boot kernel with USB connected. We should check the suspended and stopped bit before call dr_controller_run() to fix the issue. Signed-off-by: make shi <b15407@freescale.com>

2012-07-05ENGR00215592 - EPDC fb: Fix bug in selecting next LUT when 0-31 busyDanny Nold
If LUT 63 is busy and LUTs 0-31 are busy, the epdc_choose_next_lut function was not correctly selecting an available LUT between 32-62. Instead, it was returning 0. This fixes that issue by properly offsetting the available LUT from the second 32-bit segment of the 64-bit LUT field. Signed-off-by: Danny Nold <dannynold@freescale.com>

2012-07-05ENGR00215188-2 LDO bypass: disable LDO bypass before suspend and back in resumeRobin Gong
There is one SOC bug if use LDO bypass, VDDARM_CAP will take 2ms to raise up normal voltage when system resume back, longer than 40us before. Then it will cause cpu hang if resume back. Workaround: We can disable LDO bypass at the last minute of suspend and enable LDO bypass again as long as system resume back. Signed-off-by: Robin Gong <B38343@freescale.com>
2012-07-05ENGR00215188-1 PFUZE CPUFREQ: reconstruct LDO bypass functionRobin Gong
As before, raw I2C operation is added in suspend interface of cpufeq driver,so that we can raise up cpu frequency and voltage after I2C driver suspended.But the code is not platform independent if customer use another pmic whose I2C slave address is different with pfuze. Now, we rasie up cpu frequency and disable cpu frequency change in more earlier than before. If system begin to suspend flow, we will do this. Signed-off-by: Robin Gong <B38343@freescale.com>

2012-06-29ENGR00215041-2 MX6 SabreSD:Set clko parent to be clko2Liu Ying
On MX6 SabreSD board, gpio_0 is muxed to clko to be audio mclk and camera mclk. 24MHz osc clk is a stable clock source, which can meet the requirement of audio mclk and camera mclk. This patch sets clko parent clock to be clko2 clock so that camera mclk and audio mclk can source from osc clk. There are 2 benifits after applying this patch: 1) clko's original parent clock(pll4_audio_main_clk) can be gated off to save power or used by another module. 2) ov5640/ov5642 camera most settings can reach claimed 15fps or 30fps with no human eye recognizable video quality downgrade.
