Mark Featherston 54fd6b2eb1 gpio: ts4900: Do not set DAT and OE together ... [ Upstream commit 03fe003547975680fdb9ff5ab0e41cb68276c4f2 ] This works around an issue with the hardware where both OE and DAT are exposed in the same register. If both are updated simultaneously, the harware makes no guarantees that OE or DAT will actually change in any given order and may result in a glitch of a few ns on a GPIO pin when changing direction and value in a single write. Setting direction to input now only affects OE bit. Setting direction to output updates DAT first, then OE.
