Subject: [PATCH net-next 02/10] dt-bindings: arm: stm32: add compatible for syscon gcan node

From: Dario Binacchi <dario.binacchi@...rulasolutions.com>

Since commit ad440432d1f9 ("dt-bindings: mfd: Ensure 'syscon' has a
more specific compatible") it is required to provide at least 2 compatibles
string for syscon node.
This patch documents the new compatible for stm32f4 SoC to support
global/shared CAN registers access for bxCAN controllers.
