Supported features:
- Read full page data by DMA.
- Support HW ECC(one step is 1KB).
- Support 2 - 32K page size.
- Support 8 CS(depend on SoCs)
Limitations:
- No support for the ecc step size is 512.
- Untested on some SoCs.
- No support for subpages.
- No support for the builtin randomizer.
- The original bad block mask is not supported. It is recommended to use

When PMIC irq occurs, regmap-irq.c will traverse all PMIC child
interrupts from low index 0 to high index, we give fall interrupt
high priority to be called earlier than rise, so that it can be
override by late rise event. This can helps to solve key release
glitch which make a wrongly fall event immediately after rise.

The Seagate Expansion Portable Drive HDD (idVendor=0bc2, idProduct=2321) is reported to fail to work on rockchip platforms
with the following error message when do read/write operation by dd command:
xhci-hcd xhci-hcd.11.auto: Ring expansion failed
According to tkaiser's suggestion[1], we can try to increase the kernel's
coherent-pool memory size to fix this issue. The kernel coherent-pool memory
size was limited at 256KB by default. When set the DEFAULT_DMA_COHERENT_POOL_SIZE
to 1MB, the error "Ring expansion failed" can be fixed, but it still not
work with the other error message:

Bind / unbind stress testing of the USB controller on rk3399 found
that we'd often end up with lots of failures that looked like this:
phy phy-ff800000.phy.9: phy poweron failed --> -110
dwc3 fe900000.dwc3: failed to initialize core
dwc3: probe of fe900000.dwc3 failed with error -110
Those errors were sometimes seen at bootup too, in which case USB
peripherals wouldn't work until unplugged and re-plugged in.
I spent some time trying to figure out why the PHY was failing to
power on but I wasn't able to. Possibly this has to do with the fact
that the PHY docs say that the USB controller "needs to be held in
reset to hold pipe power state in P2 before initializing the Type C
PHY" but that doesn't appear to be easy to do with the dwc3 driver
today. Messing around with the ordering of the reset vs. the PHY
initialization in the dwc3 driver didn't seem to fix things.
I did, however, find that if I simply retry the power on it seems to
have a good chance of working. So let's add some retries. I ran a
pretty tight bind/unbind loop overnight. When I did so, I found that
I need to retry between 1% and 2% of the time. Overnight I found only
a small handful of times where I needed 2 retries. I never found a
case where I needed 3 retries.
I'm completely aware of the fact that this is quite an ugly hack and I
wish I didn't have to resort to it, but I have no other real idea how
to make this hardware reliable. If Rockchip in the future can come up
with a solution we can always revert this hack. Until then, let's at
least have something that works.
This patch is tested atop Enric's latest dwc3 patch series ending at:
https://patchwork.kernel.org/patch/10095527/
...but it could be applied independently of that series without any
bad effects.
