Subject: [PATCH] ARM: davinci: board-da850-evm: fix WP pin polarity for MMC/SD
Date: Thu, 17 May 2018 20:20:52 -0500 [thread overview]
Message-ID: <20180518012052.31345-1-aford173@gmail.com> (raw)
When booting from MMC/SD in rw mode, the system crashes because
the write protect pin should be active high and not active low.
This patch fixes the polarity of the WP pin.
