  This series fixes a couple of issues that occur when powering off a
board using a PMIC attached to the RSB bus.

These issues only affected 32-bit platforms, because 64-bit platforms
use PSCI for pm_power_off(), and the PSCI firmware reinitializes the
RSB controller.

Changes in v3:
 - Adjust patch 1 commit message
 - Clear the interrupt status register after polling
 - Add a patch refactoring how the status bits are cleared

Changes in v2:
 - Add Fixes tag to patch 2
 - Only check for specific status bits when polling

Samuel Holland (3):
  bus: sunxi-rsb: Remove the shutdown callback
  bus: sunxi-rsb: Support atomic transfers
  bus: sunxi-rsb: Clear interrupt status before each transfer
