2012-03-18ENGR00176974 MX6Q: make 624M WP work, change 624 WP to 672 WPimx-android-r13.2Zhang Jiejing
since pll1 have a limit that cannot scaling down to 650M and below so change the 600M WP to 672MHz. otherwise, the 600WP's clock will depens on last frequency. Signed-off-by: Zhang Jiejing <jiejing.zhang@freescale.com>

2012-03-08ENGR00176160 [MX6]Correct PLL1 freq change flowAnson Huang
Previous PLL1 freq change is done by switching CPU clock to 400M pfd or 24M OSC, then modifying PLL1 div directly, and switch back CPU clock immediately, it will result in CPU clock stop during PLL1 hardware lock period, thus, DRAM FIFO may blocked by the data CPU requested before PLL1 clock changed, and it will block other devices accessing DRAM, such as IPU, VPU etc. It will cause underrun or hang issue. We should wait PLL1 lock, then switch back. Signed-off-by: Anson Huang <b20788@freescale.com>
2012-03-07ENGR00176278 mx6: make local timer work with WAIT modeXinyu Chen
As mx6q soc use one clock to provide for cpu and local timer, the local timers will be stopped when enter wait mode. This causes system hang when enter wait mode with local timer enabled. So we should switch the clock event to GPT broadcast clock event before entering wait mode, and disable local timers. Todo this, following changes made: * In arch_idle(), we check if the GPT broadcast clock event is switched to one shot mode. If the kernel clocksource is switched from jiffies one to GPT, then we can use GPT as broadcast event. And switch from local timer to GPT broadcast event before entering mx6q_wait. Otherwise, kernel will hange if the SW jiffies clock source is used. We call clockevents_notify to switch clock source. * Remove the enable_wait_mode check in local timer setup. * Always return 0 in GPT v2 timer's set_next_event routing. All the GPTs are running in free run mode as what driver did. So we should allow the GPT CNT register roll over to 0 when it reaches 0xFFFFFFFF. And the next event written to compare register can less than the current value in CNT. If we refused to do roll over settings, the kernel will continues to set_next_event to GPT when the next event is far away and we return negative value. This is happend when one CPU is in idle and no timewheel is being expired in short time. Signed-off-by: Xinyu Chen <xinyu.chen@freescale.com>

2012-02-17ENGR00174652 i.mx6: explicitly set the LPM mode to run mode during early bootupJason Liu
the reset value of LPM[1:0] in CCM_CLPCR register is b'01, which means system will enter into wait mode on next assertion of dsm_request signal. In order to avoid the system unexpectly enter the wait mode during bootup we need set the LPM mode to run mode explicity during early boot up phase, Anytime, we want system to enter the wait mode, the sw procedure is: mxc_cpu_lp_set(LP_MODE) -> set CCM_CLPCR register -> system enter wait mode This patch also fix linux kernel reboot stress test on i.mx6dl, without this patch linux kernel reboot test will fail random with error like this: [ 12.091220] Bad mode in interrupt handler detected [ 12.096056] Bad mode in interrupt handler detected [ 12.100851] Internal error: Oops - bad mode: 0 [#1] PREEMPT SMP Signed-off-by: Jason Liu <r64343@freescale.com>
