Subject: OMAP4: Pandaboard: Fix MMC card detect gpio line
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5b59cc2fc2ff90369d6aa7862caaba3cf45b5075;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

OMAP4: Pandaboard: Fix MMC card detect gpio line

commit bf56f0a6668cd (2.6.37-rc1), from Nishanth Menon attempted
to fix card detection for PandaBoard, unfortunately, the fix missed
to initialize .gpio_cd member of omap2_hsmmc_info. This results
in a default value of '0', which is a valid GPIO line.
On PandaBoard, the side effect of this is that GPIO line 0 controls
the powering TFP410 DVI chip, and without the fix DVI chip is
inadvertently powered.
