Matthew Howell 5fdbe136ae serial: exar: Fix GPIO configuration for Sealevel cards based on XR17V35X ... Sealevel XR17V35X based devices are inoperable on kernel versions 4.11 and above due to a change in the GPIO preconfiguration introduced in commit 7dea8165f1. This patch fixes this by preconfiguring the GPIO on Sealevel cards to the value (0x00) used prior to commit 7dea8165f1 With GPIOs preconfigured as per commit 7dea8165f1 all ports on Sealevel XR17V35X based devices become stuck in high impedance mode, regardless of dip-switch or software configuration. This causes the device to become effectively unusable. This patch (in various forms) has been distributed to our customers and no issues related to it have been reported.
