Subject: [PATCH v2 0/4] Add SPI NOR DTS node for SG2042 SoC and boards using it
Date: Tue, 16 Sep 2025 21:22:49 +0800 [thread overview]
Message-ID: <20250916-sfg-spidts-v2-0-b5d9024fe1c8@gmail.com> (raw)
[PATCH 1/4] and [PATCH 2/4] are copied from patch set [1]
[PATCH v4 4/4] with content changes:
According to SG2042 Pioneer and SG2042_EVB_V1/V2 schematics, SPI-NOR Flash
cannot support QSPI due to hardware design.
Thus spi-(tx|rx)-bus-width must be set to 1.

Changes in v2:
- Change value of spi-(tx|rx)-bus-width properties to 1 of all boards.
- Decrease spi-max-frequency to 50MHz.
- Link to v1: https://lore.kernel.org/r/20250813-sfg-spidts-v1-0-99b7e2be89d9@gmail.com
