2012-09-03ENGR00222855 MX6 CPUFREQ: support three VDDSOC setpointsrel_imx_3.0.35_12.09.02Robin Gong
On MX6Q/DL , there is only two set point of VDDSOC/VDDPU, one is 1.25V(1GHz), another is 1.175V. And in arch/arm/plat-mxc/cpufreq.c will judge whether the current cpu frequency is the highest set point(1G) or not to set the right VDDSOC/VDDPU. The logic is also match to dynamic ldo bypass function, since the change point is the highest set point too. But there is three set points of VDDSOC/VDDPU in MX6SL , so the logic in cpufreq.c need to change. Now VDDSOC/VDDPU will track with VDDARM fully. Signed-off-by: Robin Gong <B38343@freescale.com>
2012-08-31ENGR00222133 MX6SL - Fix crashes caused by Low power IDLE supportRanjani Vaidyanathan
Need to ensure that the ARM_CLK rate stays exactly the same when moving ARM_CLK from PLL2_PFD_400 to PLL1 when system enters 24MHz state. Also need to ensure that PLL1 is enabled before relocking the PLL to the correct rate. Signed-off-by: Ranjani Vaidyanathan <ra5478@freescale.com>

Need to ensure that check for usecount in clk_set_parent occurs within the protection of the clock mutex. Else there is a chance that the usecount can be decremented (and the clock disabled) after the check. Also add back the code to maintain the correct usecount for pll2_pfd_400.

When system enter suspend, we increase CPUFreq to the highest point without update the global loops_per_jiffy, it will lead to udelay inaccurate during the last phase of suspend/resume. WB counter and RBC counter need at least two 32K cycles to finish, here we add 80us for safe. Signed-off-by: Anson Huang <b20788@freescale.com>

2012-08-26ENGR00221440 MX6x-Fix race-condition in checking bus_freq variablesRanjani Vaidyanathan
Checking of the bus_freq variables and changing of the bus/ddr frequency should be done under one mutex. Else there is a race-condition that the variable changed just after it was checked. Also ensure that the bus freq is always increased before the cpu freq is set to anything other than the lowest setpoint. Else there is a possibility that the ARM is set to run from PLL1 at higher frequency when bus/DDR are still at 24MHz. This is dangerous since when system enters WAIT mode in low bus freq state, PLL1 is set to bypass when ARM is being sourced from it. Signed-off-by: Ranjani Vaidyanathan <ra5478@freescale.com>

When android doing suspend/resume, we may meet the issue of backlight is not on (pwm pin no signal) after system wakeup. The root cause is PWM sample can not be set into the PWMSAR register after pwm being used and disabled for a while. The value read back after write is 0 when this issue happens.

Add the new WAIT mode workaround added for MX6Q1.2 and MX6DLTO1.1. A new bit is added to CCM_CGPR (bit 17). This bit needs to be enabled for the WAIT mode fix to be active and needs to be disabled before the system enters STOP mode with power gating enabled. Fix WAIT mode bug when system is in low power IDLE mode: In low power IDLE mode (AHB @ 24MHz), switch ARM to run from 24MHz on MX6QTO1.1 and MX6DLTO1.0 chips when ARM core enters WAIT mode. We still need to use the ARM:IPG_CLK ratio of 12:5. Since IPG_CLK is at 12MHz, we need to run ARM below 28.8MHz. Signed-off-by: Ranjani Vaidyanathan <ra5478@freescale.com>

2012-07-20ENGR00215182-1 sabresd: Add basic support for HDMI CECZhang Xiaodong
- Changes to IOMUX to allow HDMI CEC controller to use KEY_ROW2 pin that it needs - Add cec device in platform-mxc_hdmi.c - Add MXC_HDMI_CEC in imx6_defconfig Signed-off-by: Zhang Xiaodong <B39117@freescale.com>
2012-07-20ENGR00215491 [MX6]Need to increase BUS freq when CPU freq is increasedAnson Huang
When BUS freq is running at DLL off mode(24M or 50M), when CPU freq is increased, we need to increase BUS freq to 400M setpoint in order to achieve high performance when CPU is busy. Signed-off-by: Anson Huang <b20788@freescale.com>

2012-07-20ENGR00215188-1 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>
2012-07-20ENGR00214813 MX6DL SabreSD : Kernel, Enable ARM Perfromance MonitorEric Sun
Register PMU resources during system bootup, so that "Perf" Command can be used to get misc performance data of a running program The "Perf" Exe should be built manually in "./tools/perf" using the following command line > make CROSS_COMPILER=... ARCH=arm CFLAGS="-static -DGElf_Nhdr=Elf32_Nhdr" then copy the "Perf" executable to rootfs/bin Usage : perf # show help content perf list # show all available statistics options perf stat ls # show all statistics of a "ls" command perf stat -e cycles tar cvfz bin.tgz /bin # show "cycles" statistics of command # "tar cvfz ...." MX6 Series Chips bound all CPUs PERFMON IRQ to one, this may cause some problems when get per-CPU statistics. Need further investigation Signed-off-by: Eric Sun <jian.sun@freescale.com>
