4.17-stable review patch. If anyone has any objections, please let me know.
------------------ From: Nick Dyer <[email protected]> commit 06d793b114e9d922c03aa077ac6c5c51fdda2722 upstream. The pinctrl settings were incorrect for the touchscreen interrupt line, causing an interrupt storm. This change has been tested with both the atmel_mxt_ts and RMI4 drivers on the RDU1 units. The value 0x4 comes from the value of register IOMUXC_SW_PAD_CTL_PAD_CSI1_D8 from the old vendor kernel.
