Linus Walleij e44d1e17da gemini: Add v4.19 kernel patches
This is the remainder of kernel patches for the v4.19
kernel. A whole slew of the previous patch stack is now
upstream, so this mainly contains the stuff that was
added upstream between v4.19 and v5.0-rc1, and then
the USB FOTG201 patches from Hans.

Subject: [PATCH 01/18] pinctrl: gemini: Mask and set properly
The code was written under the assumption that the
regmap_update_bits() would mask the bits in the mask and
set the bits in the value.
It missed the points that it will not set bits in the value
unless these are also masked in the mask. Set value bits
that are not in the mask will simply be ignored.
Fixes: 06351d133dea ("pinctrl: add a Gemini SoC pin controller")
