Cover letter [PATCH v2 0/2] I2C support for NXP LPC18xx family
Quoted 21 lines · Joachim Eastwood
This patch set adds a I2C driver and documentation for the I2C peripheral found on many NXP LPC MCUs.
The driver is a rework of an old driver by Kevin Wells. It has been modified to support modern resource allocation, device tree and generally cleaned up. Driver was originally written to support the LPC2xxx platforms.
Patches based on i2c/for-next and tested on Embedded Artists' LPC4357 Dev Kit and Hitex LPC4350 Eval board with several I2C devices.
This version address comments from Wolfram Sang.
Changes since v1:
- removedev_dbg()leftovers from development/debugging
- usei2c_add_adapter
- change return value on NACK and arb lost
(I think all the others should be okay as they are)
- fix 80 char warnings (involved s/reg_base/base)
- rebase on i2c/for-next
