The procedure of rpm_idle() is as follows.
rpm_idle
->rpm_suspend
->pm_genpd_runtime_suspend
->pm_clk_suspend
->clk_disable
->genpd_poweroff
Pm_runtime_put(dev) causes rpm_idle() to be queued up, when
pm_clk_suspend() is executed, the rockchip dmcfreq lock is
released, vop clocks may be closed while changing ddr frequency.
Use pm_runtime_put_sync() instead of pm_runtime_put(), so that
rpm_idle can be executed before the lock is released.

There is a hardware mistake on firefly board, it will cause the
vdd_log is too low based on previous parameter, so we change the
pwm parameter to make sure the vdd_log is about 0.9v.

If cpu frequency was 1.0 GHz, bluetooth music is unstable. But it
is stable when cpu frequency is 400 MHz. Although I had test the
uart dma driver many days on rk3088, maybe the cpu frequency was low,
and I couldn't produce the issue. In one word, the code is unlogical.
The new logic is that increase the fifo water level, if dmac bursts
before it, wait until dmac finishes and read the rest data.
If dmac doesn't burst after it, then read data from fifo directly.

Move rkisp1 and gc0312/gc2145, cif and cif_sensor
node config to dts level not in dtsi.
For rkisp1 and gc0312/gc2145 don't need by rk3326-863-lp3-v10.dts,
otherwise it causes 8.0 863 machine camera register failed;
And cif with cif_sensor don't need by rk3326-863-lp3-v10-avb.dts,
otherwise it causes 9.0 863 machine camera register failed;
So need to modify rk3326-863-lp3-v10-avb.dts and
rk3326-863-lp3-v10.dts separately for camera node configs

If a function sets bind_deactivated flag, upon removal we will be left
with an unbalanced deactivation. Let's make sure that we conditionally
call usb_function_activate() from usb_remove_function() and make sure
usb_remove_function() is called from remove_config().
