Subject: [PATCH 00/13] net: can: Add can support for TI platforms

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.

The patches 4 to 13 add adaptation details for am43xx and dra7x Socs and
EVMs.

cheers,
-roger
