From 6d87552c0b86b9677d762002082df5f5b7e3c33f Mon Sep 17 00:00:00 2001 From: Rohit Ner Date: Wed, 12 Apr 2023 13:20:09 -0700 Subject: [PATCH] spi: spi-loopback-test: Add module param for iteration length SPI test framework is designed to run each test case for a list of lengths. Introduce a module parameter to limit the iterations to a single value among the list of lengths.
