Subject: [PATCH 0/3] spi: uniphier: introduce polling mode and fix bug

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
  spi: uniphier: introduce polling mode
