It is similar to the eKTF2127, but it uses a different packet type and format to report touch events. My understanding of the packet format is based on the Kobo Arua vendor kernel: https://github.com/neuschaefer/linux/blob/vendor/kobo-aura/drivers/input/touchscreen/elan_touch_i2c.c#L237 Jonathan Neuschäfer (3): dt-bindings: input: ektf2127: Add elan,ektf2132 compatible string Input: ektf2127 - Add support for eKTF2132 touchscreen ARM: dts: imx50-kobo-aura: Enable eKTF2132 touchscreen .../bindings/input/touchscreen/ektf2127.txt | 2 +- arch/arm/boot/dts/imx50-kobo-aura.dts | 16 +++++++++- drivers/input/touchscreen/ektf2127.c | 32 ++++++++++++++++++- 3 files changed, 47 insertions(+), 3 deletions(-) --- 2.28.0
