[PATCH 0/5] ARM: STM32: Add compatibles for syscon nodes

[Benjamin Gaignard]

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 series update the syscon of the STM32 SoCs to fix the reported errors.

[PATCH 1/5] dt-bingings: arm: stm32: Add compatibles for syscon nodes

[Benjamin Gaignard]

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 document the missing compatibles for stm32 SoCs.
