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.
