Subject: [PATCH 0/2] mmc: dw_mmc: fix the wrong operation for reset controller
Date: Mon, 31 Oct 2016 11:49:40 +0900 [thread overview]
Message-ID: <20161031024942.4415-1-jh80.chung@samsung.com> (raw)
This patch adds the "reset-names" as reset controller for dwmmc controller.
Linaro guys had reported the issue about booting stuck.
Some SoCs are enabled the CONFIG_RESET_CONTROLLER.
then dwmmc controller are waiting for getting reset controller.
But if doesn't define "resets" property in device-tree, it should be stuck.
If use the reset-names as reset controller for dwmmc controller,
it's more stable than now.
This commit is related with the below commit.
Fixes: d6786fefe816 ("mmc: dw_mmc: add reset support to dwmmc host controller")
