vcc18_lcd is the power enable pin of dsi panel board, and it
also provides the rst signal of panel through RC circuit.
When we power on and change the pin directly, the rst will not
power down completely, resulting in the probability that the
screen cannot display after reboot.
so fix it.

As dmac aclk comes from hclk pdbus, dmac pclk comes frome pclk pdbus,
dmac aclk should be an integer multiple of dmac pclk and the same
parent with dmac pclk. so let hclk pdbus and pclk pdbus only come from gpll.

If the parent of one clock is cpll and we set it as dummy clock, the
clock will be a orphan clock and the clk provider will register abortively,
as follows.
[ 0.000000] rockchip_clk_of_add_provider: could not register clk provider
The cause of the error:
struct clk *__clk_create_clk(struct clk_hw *hw, const char *dev_id,
const char *con_id, bool with_orphans)
{
/* This is to allow this function to be chained to others */
if (!hw || IS_ERR(hw))
return (struct clk *) hw;
if (hw->core->orphan && !with_orphans)
return ERR_PTR(-EPROBE_DEFER);
return clk_hw_create_clk(hw, dev_id, con_id);

There is no reason to limit the performance on the 'NO-FLUSHP' SoCs,
cuz these platforms are just that the 'FLUSHP' instruction is broken.
so, remove the limit to improve the efficiency.

Commit 8099f58f1e ("USB: hub: Don't record a connect-change event
during reset-resume") wasn't very well conceived. The problem it
tried to fix was that if a connect-change event occurred while the
system was asleep (such as a device disconnecting itself from the bus
when it is suspended and then reconnecting when it resumes)
requiring a reset-resume during the system wakeup transition, the hub
port's change_bit entry would remain set afterward. This would cause
the hub driver to believe another connect-change event had occurred
after the reset-resume, which was wrong and would lead the driver to
send unnecessary requests to the device (which could interfere with a
firmware update).
The commit tried to fix this by not setting the change_bit during the
wakeup. But this was the wrong thing to do; it means that when a
device is unplugged while the system is asleep, the hub driver doesn't
realize anything has happened: The change_bit flag which would tell it
to handle the disconnect event is clear.
The commit needs to be reverted and the problem fixed in a different
way. Fortunately an alternative solution was noted in the commit's
Changelog: We can continue to set the change_bit entry in
hub_activate() but then clear it when a reset-resume occurs. That way
the the hub driver will see the change_bit when a device is
disconnected but won't see it when the device is still present.
That's what this patch does.

Commit 428826f535 ("fdt: add support for rng-seed") moves of_fdt_crc32
from early_init_dt_verify() to early_init_dt_scan() since
early_init_dt_scan_chosen() may modify fdt to erase rng-seed.
However, arm and some other arch won't call early_init_dt_scan(), they
call early_init_dt_verify() then early_init_dt_scan_nodes().
Restore of_fdt_crc32 to early_init_dt_verify() then update it in
early_init_dt_scan_chosen() if fdt if updated.
