From ab5c0191e1c1def972728a6b2a0804ee8c8211e8 Mon Sep 17 00:00:00 2001 From: Dario Binacchi Date: Wed, 25 Feb 2026 17:16:54 +0100 Subject: test: spi: add sandbox_spi_get_wordlen interface Add the sandbox_spi_get_wordlen() public interface to retrieve the internal word length state of the sandbox SPI device. This is intended for use in sandbox SPI test cases to verify that the word length is correctly propagated from the SPI uclass to the driver.
