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 --- Afzal Mohammed (1): arm: dts: am4372: Add dcan nodes Dave Gerlach (1): ARM: dts: am437x-gp-evm: Add pinctrl sleep states for dcan pins Mugunthan V N (1): arm: dts: am437x-gp: Add dcan support Roger Quadros (10): can: c_can_platform: Fix c_can_hw_raminit_ti() and add timeout net: can: c_can: Add syscon/regmap RAMINIT mechanism net: can: c_can: Add support for START pulse in RAMINIT sequence ARM: dts: dra7: Add syscon regmap for CORE CONTROL area ARM: dts: DRA7: Add DCAN nodes ARM: dts: dra7-evm: Add CAN support ARM: dts: dra72-evm: Add CAN support ARM: dts: AM43xx: Add aliases to d_can nodes ARM: dts: am4372: Add control module syscon node ARM: dts: am4372: Add dcan raminit bits .../devicetree/bindings/net/can/c_can.txt | 10 ++ arch/arm/boot/dts/am4372.dtsi | 35 ++++++ arch/arm/boot/dts/am437x-gp-evm.dts | 42 ++++++++ arch/arm/boot/dts/dra7-evm.dts | 21 ++++ arch/arm/boot/dts/dra7.dtsi | 35 ++++++ arch/arm/boot/dts/dra72-evm.dts | 23 ++++ drivers/net/can/c_can/c_can.h | 12 ++- drivers/net/can/c_can/c_can_platform.c | 120 ++++++++++++++++----- 8 files changed, 270 insertions(+), 28 deletions(-) -- 1.8.3.2 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
