[rtc-linux] [PATCH 3/5] ARM: Orion5x: ts78xx: allow rtc-m48t86 to manage it's own resources
From: H Hartley Sweeten <hsweeten@visionengravers.com>
Date: 2017-02-15 16:36:50
Subsystem:
arm port, arm/marvell dove/mv78xx0/orion soc support, arm/orion soc/technologic systems ts-78xx platform support, the rest · Maintainers:
Russell King, Andrew Lunn, Sebastian Hesselbarth, Gregory Clement, Alexander Clouter, Linus Torvalds
The rtc-m48t86 driver can now handle it's own resources and do the read/write operations internally. Pass the necessary resources to the driver and remove the m48t86_ops platform data.
