Subject: [PATCH v5 0/6] Add spi-hid, transport for HID over SPI bus
Date: Thu, 7 Jul 2022 09:58:56 -0700 [thread overview]
Message-ID: <20220707165902.3184-1-jaschultzMS@gmail.com> (raw)
From: Jarrett Schultz <jaschultz@microsoft.com>
Surface Duo devices use a touch digitizer that communicates to the main
SoC via SPI and presents itself as a HID device. This patch's goal is to
add the spi-hid transport driver to drivers/hid. The driver follows the
publically available HID Over SPI Protocol Specification version 1.0.
The specification is available at
https://www.microsoft.com/en-us/download/details.aspx?id=103325.
In the initial commits there are some HID core changes to support a SPI
device, a change to HID documentation, HID over SPI Device Tree
bindings, and finally the SPI HID transport driver.
Dmitry Antipov (5):
HID: Add BUS_SPI support when printing out device info in
hid_connect()
HID: define HID_SPI_DEVICE macro in hid.h
dt-bindings: input: Document Microsoft G6 Touch Digitizer
Documentation: Correction in HID output_report callback description.
HID: add spi-hid, transport driver for HID over SPI bus
Jarrett Schultz (1):
