Subject: [PATCH v2 0/3] Add quad mode support for QPIC SNAND
Date: Fri, 07 Aug 2026 21:33:54 +0530 [thread overview]
Message-ID: <20260807-quad-v2-0-8ec821e2f22b@oss.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.

Changes in v2:
- Removed incorrect if check
- Updated snandc->qspi->cmd with quad command for further read in quad
mode.
- Link to v1: https://lore.kernel.org/r/20260716-quad-v1-0-636f74da17e1@qti.qualcomm.com
