[RESEND PATCH v2 0/3] mfd: syscon: Add optional clock support needed on stm32

From: Fabrice Gasnier
Date: Mon Jan 07 2019 - 05:08:30 EST

STM32 syscfg registers are accessed using syscon. It needs syscfg clock
to be enabled while accessing registers.
This adds support for optional clock on syscon, and the relevant clock
in stm32mp157 device tree.

Changes in v2:
- move clocks to specific bindings using syscon as per Rob's comment

Fabrice Gasnier (3):
dt-bindings: stm32: syscon: add clock support
mfd: syscon: Add optional clock support
ARM: dts: stm32: Add clock on stm32mp157c syscfg
