-Subject: [PATCH 381/773] overlays: Fix multiple-instantiation of sc16is7xx*
-
-The registration of the fixed clocks uses the node name as the clock
-name, causing a clash if two clock nodes have the same name, regardless
-of the path to the node. Fix the issue by overwriting the clock node
-names using the value of the "addr" parameter, providing a crude
-disambiguation. (A bit of string pasting to form "sc16is752_clk_<addr>"
-would have been nice, but that is outside the abilities of the overlay
-parameter mechanism.)
-
-Also give the sc16is750-i2c overlay the xtal parameter for symmetry.
-
-See: https://www.raspberrypi.org/forums/viewtopic.php?f=107&t=235650
