Move struct sunxi_ccm_reg pointer to private structure
so-that accessing ccm reg base become more proper way
and avoid local initialization in each function.

Keep this, so you don't have to modify every setbits()/... down below.

I'm keeping ccm base in priv, so-that resigning base in remove can
avoid and use the priv->ccm where ever possible.

This just grows the patch size and requires more typing in case someone
decides to add another register access. I don't see any benefit for
this, so keep the local variable, it costs nothing and makes the code
easier.

Filling musb_hdrc pdata using structure will unnecessary
add extra ifdefs, so fill them inside probe call for
better code understanding and get rid ifdefs using
devicetree compatible.

Make this pdata = musb_plat and then tweak pdata down below to avoid
assigning all the values there.

Thought the same, but we have hardly two members power and
platform_ops and reaming mode and other need to assign with SOC basic
and CONFIG_

Unlike other Allwinner SOC's H3/H5/V3s OTG support 4 endpoints
with relevant fifo configs, rest all have 5 endpoints.
So add the fifo configs and defer them based on udevice_id compatible.

Instead of this, use the compatible's .data to pass the
musb_config(_h3). Then you can do
pdata.config = dev_get_driver_data(dev);

We've only diff with H3 compared to all other SOC's and this make
assigning same musb_config to non-H3 platforms, which will increasing
some bytes(as of now 16bytes we have a10,a33, a31 and h3). compatible
check here look suitable, I think.

The driver data are in the U-Boot binary anyway, just not used and thus
set to 0 . By adding this check, you're actually growing the size.
The driver data are there for this exact purpose -- associating metadata
with compatible strings, metadata which are to be used by the driver (ie
in probe() function). What you're doing here with the compatible check
is wrong.

clock gating bits on a64 are different than H3_H5, so fixed
only required bits on clock_sun6i.h.

Note:
Since the driver is dm-driver, we even add SOC changes based on
compatible or driver_data but here few of the reset and clock bits
and register offset memebers are in SOC includes files.
I even try to add driver code by adding config structure in .data
but that eventually increasing size.
All these code will anyway move to clock and reset framework
once dm support added.

Like other Allwinner SoC, the H3/H5/A64 is missing the config register
from the musb hardware block. Use a known working value for it
like other SoC.

USB PHY implementation for Allwinner SOC's can be handling
in to single driver with different phy configs.
This driver handle all Allwinner USB PHY's start from 4I to
50I(except 9I). Currently added A64 compatibility more will
add in next coming patches.
Current implementation is unable to get pinctrl, clock and reset
details from DT since the dm code on these will add it future.
Driver named as phy-sun4i-usb.c since the same PHY logic
work for all Allwinner SOC's start from 4I to A64 except 9I
with different phy configurations.

Get rid of any static variables in this driver. And the delay should
come from DT .

You should probably match on some type of the block here, not register
offset, to identify the SoC .

Unlike, other Allwinner SUN4I Phy supporting SOC, A83T has
2 USB PHY's and second one is HSIC. So phy control need to
configure to handle these HSIC and SIDDQ requirement.

The sunxi otg phy has a bug where it wrongly detects a high speed squelch
when reset on the root port gets de-asserted with a lo-speed device.
The workaround for this is to disable squelch detect before de-asserting
reset, and re-enabling it after the reset de-assert is done. Add a sunxi
specific phy function to allow the sunxi-musb glue to do this.

To: u-boot
Allwinner USB PHY handling can be done through driver-model
generic-phy so add the generic-phy ops to relevant places
on host and musb sunxi driver and enable them in respective
SOC's.
