From f1ba938e4f98941dc2b77795062e49444ec1fee1 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 19 Jan 2022 00:09:13 +0100 Subject: spi: s3c64xx: Delete unused boardfile helpers The helpers to use SPI host 1 and 2 are unused in the kernel and taking up space and maintenance hours. New systems should use device tree and not this, so delete the code.
