Subject: [PATCH v2] arm64/hisilicon: fix SDcard detection
Date:   Mon, 14 Jan 2019 09:24:34 +0100
Message-Id: <1547454274-1674-1-git-send-email-vincent.guittot@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The SDcard detection of hikey960 is active low so cd-inverted is wrong.
Instead of adding cd-inverted, we should better set correctly cd-gpios
to use GPIO_ACTIVE_LOW.

SD card detection was not working on v5.0-rc1 but patch
https://marc.info/?l=linux-mmc&m=154637189021211&w=2 makes it work.
Nevertheles, latest changes in of_mmc_detection makes possible to have 
a correct DT config.
