Subject: [PATCH 0/3] spi: uniphier: introduce polling mode and fix bug
Date: Tue, 3 Sep 2019 14:30:58 +0900 [thread overview]
Message-ID: <1567488661-11428-1-git-send-email-hayashibara.keiji@socionext.com> (raw)
This series introduces new polling mode and fixes bug.
- Introduce new polling mode for short size transfer. Either the estimated
transfer time is estimated to exceed 200us, or polling loop actually exceeds
200us, it switches to irq mode.
- Fix a bug of register overwrite.
- Minor corrections.
Keiji Hayashibara (3):
spi: uniphier: fix wrong register overwrite
spi: uniphier: remove unnecessary code
