Subject: [PATCH 0/3] Add quad mode support for QPIC SNAND
Date: Thu, 16 Jul 2026 10:57:44 +0530 [thread overview]
Message-ID: <20260716-quad-v1-0-636f74da17e1@qti.qualcomm.com> (raw)
The Qualcomm QPIC SPI-NAND controller supports both single (x1) and
quad (x4) transfer modes, however the current driver operates only in
single-bit mode. This series adds support for quad data transfers and
includes a vendor-specific fix required for Macronix SPI-NAND devices.
