From cb15abd47806b449e853caf43f41573c4c82fed3 Mon Sep 17 00:00:00 2001 From: Tudor Ambarus Date: Fri, 14 Feb 2025 07:32:51 +0000 Subject: [PATCH] spi: s3c64xx: extend description of compatible's fifo_depth The FIFO depth specified with the compatibles's data is used where all the instances of the IP define the same FIFO depth. It naturally has higher precedence than the FIFO depth specified via DT. Specifying FIFO depth in DT becomes superfluous in this case. Extend comment about compatible's FIFO depth.
