Subject: [PATCH v3] clk: stm32: add configuration flags for each of the stm32 drivers
Date:   Mon, 12 Mar 2018 10:32:48 +0100
Message-Id: <20180312093248.27512-1-benjamin.gaignard@st.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add two configuration flags to be able to not compile all the time
stm32f and stm32h7 drivers when ARCH_STM32 is set.
That help to save some space on those small platforms.
