Subject: [PATCH 2/3] devicetree: phy: rockchip-emmc: Document changed
 strobe-pulldown property

From: Folker Schwesinger <dev@...ker-schwesinger.de>

Document the changes regarding the optional strobe-pulldown property.
These changes are necessary as the default behavior of the driver was
restored to the Rockchip kernel behavior of enabling the internal
pulldown by default.

Fixes: f34e43f12382 ("devicetree: phy: rockchip-emmc: pulldown property")
