Hi,

Here are 2 important fixes and a code improvement to the T-Head TH1520
pinctrl driver that was either introduced or missed when Drew took over
upstreaming it.

It is based on Linus' pinctrl/for-next:

  6dbd1577b7dc ("Merge branch 'devel' into for-next")

Emil Renner Berthing (3):
  pinctrl: th1520: Fix pinconf return values
  pinctrl: th1520: Update pinmux tables
  pinctrl: th1520: Factor out casts

Hi Linus,

Which branch did you apply these patches to?

I don't see them in your devel branch [1].

Thanks,
Drew

Emil informed me that the out-of-tree USB driver is broken when trying
to use the pinctrl-th1520 driver that I submitted. This is because I
had changed -ENOTSUPP to -EOPNOTSUPP to silence a checkpatch warning
without realizing the implication. I've just been working on the
dwmac etherenet series [1] on top of mainline and I didn't realize there
was a problem with gpio.

I've just rebuilt and booted okay on lpi4a and beaglev ahead with this
series. For the whole series:
