4.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sekhar Nori <nsek...@ti.com>
[ Upstream commit 67c6b6ff221f807180aea6dd597246f87e1dd98a ]
The GPIO chip is called davinci_gpio.0 in legacy mode. Fix it, so that
mmc can correctly lookup the wp and cp gpios. Also fix the GPIO numbers
as they are not offsets within a bank.
Note that it is the gpio-davinci driver that sets the gpiochip label to
davinci_gpio.0.
Fixes: bdf0e8364fd3 ("ARM: davinci: da850-evm: use gpio descriptor for mmc
pins")
