i2c: parport-light: remove driver

2020-01-15T17:18:34Z

The justification of a light version of the parport driver was less overhead for embedded systems. Well, today, even if an embedded system still has a parport, it surely can handle the fully-fledged parport driver. Remove it to reduce the maintenance burden.

i2c: Add i2c-icy for I2C on m68k/Amiga

2019-08-29T19:04:11Z

This is the i2c-icy driver for the ICY board for Amiga computers. It connects a PCF8584 I2C controller to the Zorro bus, providing I2C connectivity. The original documentation can be found on Aminet: https://aminet.net/package/docs/hard/icy IRQ support is currently not implemented, as i2c-algo-pcf is built for the ISA bus and a straight implementation of the same stack locks up a Zorro machine.

i2c: mt7621: Add MediaTek MT7621/7628/7688 I2C driver

2019-06-26T13:19:01Z

This patch adds a driver for the I2C controller found on the MediaTek MT7621/7628/7688 SoC's. The base version of this driver was done by Steven Liu (according to the copyright and MODULE_AUTHOR lines). It can be found in the OpenWRT repositories (v4.14 at the time I looked). The base driver had many issues, which are disccussed here: https://en.forum.labs.mediatek.com/t/openwrt-15-05-loads-non-working-i2c-kernel-module-for-mt7688/1286/3 >From this link an enhanced driver version (complete rewrite, mayor changes: support clock stretching, repeated start, ACK handling and unlimited message length) from Jan Breuer can be found here: https://gist.github.com/j123b567/9b555b635c2b4069d716b24198546954 This patch now adds this enhanced I2C driver to mainline. Changes by Stefan Roese for upstreaming: - Add devicetree bindings - checkpatch clean - Use module_platform_driver() - Minor cosmetic enhancements - Removed IO warpped functions - Use readl_relaxed_poll_timeout() and drop poll_down_timeout() - Removed superfluous barrier() in mtk_i2c_reset() - Use i2c_8bit_addr_from_msg() - Added I2C_FUNC_PROTOCOL_MANGLING - Removed adap->class = I2C_CLASS_HWMON | I2C_CLASS_SPD; Signed-off-by: Stefan Roese Tested-by: René van Dorst Signed-off-by: Wolfram Sang

i2c: Add drivers for the AMD PCIe MP2 I2C controller

2019-03-25T14:21:17Z

MP2 controllers have two separate busses, so may accommodate up to two I2C adapters. Those adapters are listed in the ACPI namespace with the "AMDI0011" HID, and probed by a platform driver. Communication with the MP2 takes place through MMIO registers, or through DMA for more than 32 bytes transfers. This is major rework of the patch submitted by Nehal-bakulchandra Shah from AMD (https://patchwork.kernel.org/patch/10597369/). Most of the event handling of v3 was rewritten to make it work with more than one bus (e.g on Ryzen-based Lenovo Yoga 530), and this version contains many other improvements.

i2c: at91: split driver into core and master file

2019-03-24T21:41:51Z

The single file i2c-at91.c has been split into core code (i2c-at91-core.c) and master mode specific code (i2c-at91-master.c). This should enhance maintainability and reduce ifdeffery for slave mode related code. The code itself hasn't been touched. Shared functions only had to be made non-static. Furthermore, includes have been cleaned up.

i2c: i2c-qcom-geni: Add bus driver for the Qualcomm GENI I2C controller

2018-07-31T19:17:20Z

This bus driver supports the GENI based i2c hardware controller in the Qualcomm SOCs. The Qualcomm Generic Interface (GENI) is a programmable module supporting a wide range of serial interfaces including I2C. The driver supports FIFO mode and DMA mode of transfer and switches modes dynamically depending on the size of the transfer.
