Subject: [PATCH] ARM: davinci: board-da850-evm: fix WP pin polarity for MMC/SD
Git-commit: 1b6fe9798af8cb7d80fad5dd30ee1bcd1e0f51eb
Patch-mainline: v4.18-rc3
References: bsc#1051510
When booting from MMC/SD in rw mode on DA850 EVM, 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.
