Subject: [PATCH v2 0/3] net: can: Use syscon regmap for TI specific RAMINIT register

Hi,

Some hardware (TI am43xx) has a buggy RAMINIT DONE mechanism and it might
not always set the DONE bit. This will result in a lockup in c_can_hw_raminit_wait_ti(),
so patch 1 adds a timeout mechanism there.

There is a non compliancy within TI platforms with respect to the
layout of the RAMINIT register. The patches 2 and 3 address this issue
and make a flexible but standard way of defining the RAMINIT hardware register
layout in the device tree. The RAMINIT register is accessed using the syscon
regmap framework.

Patches available at
git@...hub.com:rogerq/linux.git	[for-v3.18/can]

Changelog:

v2:
- added "ti" vendor prefix to TI specific raminit properties.
- split DTS changes into a separate series

cheers,
-roger
