From af4b2dc4810380a469dcd7508923b70892c2996a Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Fri, 9 Jan 2026 18:18:00 +0100 Subject: [PATCH] spi: spi-mem: Create a repeated address operation In octal DTR mode addresses may either be long enough to cover at least two bytes (in which case the existing macro works), or otherwise for single byte addresses, the byte must also be duplicated and sent twice: on each front of the clock. Create a macro for this common case.
