Commit Message

Simon Horman June 21, 2019, 9:13 a.m. UTC 
From: Geert Uytterhoeven <geert+renesas@glider.be>

Add support for input switches SW1-3 on the Renesas RZ/A1 RSK+RZA1
development board.

Note that this uses the IRQ interrupts, as the RZ/A1 GPIO controller
does not include interrupt support.
