Subject: [PATCH v3 0/4] HID: touchscreen: add himax hid-over-spi driver
Hello,
This patch series adds the driver for Himax HID-over-SPI touchscreen ICs.
This driver takes a position in [1], it intends to take advantage of SPI
transfer speed and HID interface.
Patch 1 adds the Maintainer and devicetree bindings document for driver.
Patch 2-4 adds the driver itself, Kconfig and Makefiles. Due to server
could not receive patch >100000 chars, patch separate into 3 parts.
