From 3ff9027ca6b00e194d2eae353febf7233cfcc1ea Mon Sep 17 00:00:00 2001 From: Roger Quadros Date: Fri, 14 Nov 2014 17:37:39 +0200 Subject: can: c_can: Add syscon/regmap RAMINIT mechanism Some TI SoCs like DRA7 have a RAMINIT register specification different from the other AMxx SoCs and as expected by the existing driver. To add more insanity, this register is shared with other IPs like DSS, PCIe and PWM. Provides a more generic mechanism to specify the RAMINIT register location and START/DONE bit position and use the syscon/regmap framework to access the register.
