65d0a16dce ARM: imx: Correct the comments in time.c
The comments were corrected as the following to reflect
the real situation of Freescale MXC timer IP block.
There are totally 4 version of the timer on Freescale i.MX SoCs.

35e2916f70 ARM: imx6: initialize CCM_CLPCR_LPM into RUN mode earlier
Commit 4631960d26da ("ARM: imx6: set initial power mode in pm function")
moves imx6_set_lpm() from clock init function into
imx6_pm_common_init().  This causes a hang when cpuidle support is
enabled.  The reason for that is ARM core clock is shut down
unexpectedly by WAIT mode.  It happens with the following call stack:

    cpuidle_register_governor()
        cpuidle_switch_governor()
            cpuidle_uninstall_idle_handler()
                synchronize_sched()
                    wait_rcu_gp()
                        wait_for_completion()

When wait_for_completion() is called as above, all cores are idle/WFI.
Hence, the reset value of CCM_CLPCR_LPM - WAIT mode, will trigger a
hardware shutdown of the ARM core clock.

To fix the regression, we need to ensure that CCM_CLPCR_LPM is
initialized into RUN mode earlier than cpuidle governor registration,
which is a postcore_initcall.  This patch creates function
imx6_pm_ccm_init() to map CCM block and initialize CCM_CLPCR_LPM into
RUN mode, and have the function called from machine .init_irq hook,
which should be early enough.

8fb76a07e2 ARM: imx6: set initial power mode in pm function
Rather than setting initial low-power mode in every single i.MX6 clock
initialization function, we should really do that in pm code.  Let's
move imx6q_set_lpm(WAIT_CLOCKED) call into imx6_pm_common_init().

While at it, let's rename the function to imx6_set_lpm() since it's
actually common for all i.MX6 SoCs.

3a7c01d75f ARM: dts: Add Odroid XU3 Lite support
The Odroid XU3 Lite is almost the same as XU3, except:
1. Lower CPU frequencies (1.8 GHz for A15 and 1.3 GHz for A7, instead of
   2.0 GHz and 1.4 GHz).
2. No DisplayPort.
3. No TI INA231 energy measurement sensors.

This patch moves common nodes (which is almost everything) to a common
DTSI file and adds a new XU3 Lite DTS.

Currently in comparison to XU3, only the INA231 sensors are disabled to
remove the warning:

This patch:
   - hooks up PWM to its pincontrol, and documents what

   - switches the LEDs that are on PWM outputs to use PWM
     rather than GPIO.

The main effect is that the brightness of the LEDs can be controlled, and
user-mode fan control is enabled via /sys/class/pwm

4eb0f25fa6 ARM: dts: sun8i-a33: Add dts for Sinlinx SinA33 development board.
The SinA33 is a core/SDK development board by Sinlinx. The core board
does not have any connectors or pads, other than the pads used to connect
it to the SDK board.

The core board only has the A33 SoC, 2 RAM chips, an eMMC flash chip,
the AXP223 PMIC, and supporting discrete components. eMMC is optional.

The SDK board has a USB host, USB OTG, volume control and home buttons,
audio input/output jacks, a micro-SD slot, camera and SDIO expansion
headers, an LCD connector, and a GPIO expansion header, which has
UARTs, MIPI DSI and I2C available. Only UART0 is enabled though.
