Subject: [PATCH 0/6] i2c: spacemit: fix and introduce pio
Date: Wed, 27 Aug 2025 15:39:07 +0800 [thread overview]
Message-ID: <20250827-k1-i2c-atomic-v1-0-e59bea02d680@linux.spacemit.com> (raw)
Previously, there were a few latent issues in the I2C driver.
These did not manifest under interrupt mode, but they were
still present and could be triggered when running in PIO mode.
This series addresses those issues and adds support for PIO
mode transfers.
