Geopandas plot with contextily basemap south face up

Question

I was wondering if it is possible to plot a map using geopandas and contextily basemaps in an orientation other than North up.

Example code with a map that I would like to plot upside down, but with the basemaps labels right-side up:

import osmnx as ox
import geopandas as gpd
import contextily as cx

berlin = ox.geocode_to_gdf("Berlin,Germany")
fig, ax = plt.subplots(1, 1, figsize=(10, 10))
_ = ax.axis("off")

berlin.plot(
    ax=ax,
    color="None",
    edgecolor="black",
)

# basemap
cx.add_basemap(
    ax,
    crs=berlin.crs,
)

plt.savefig(
    "stackoverflow_question.png",
    dpi=100,
    bbox_inches="tight",
)
