Subject: [PATCH v11 0/4] Add Intel LJCA device driver
Date: Tue, 29 Aug 2023 12:54:04 +0800 [thread overview]
Message-ID: <1693284848-29269-1-git-send-email-wentong.wu@intel.com> (raw)
Add driver for Intel La Jolla Cove Adapter (LJCA) device. This
is a USB-GPIO, USB-I2C and USB-SPI device. We add 4 drivers to
support this device: a USB driver, a GPIO chip driver, a I2C
controller driver and a SPI controller driver.
---
v11:
- switch dev_err to dev_dbg for i2c-ljca driver
- remove message length check because of defined quirk structure
- remove I2C_FUNC_SMBUS_EMUL support
v10:
- remove ljca_i2c_format_slave_addr
- remove memset before write write w_packet
- make ljca_i2c_stop void and print err message in case failure
- use dev_err_probe in ljca_i2c_probe function
v9:
- overhaul usb-ljca driver to make it more structured and easy understand
- fix memory leak issue for usb-ljca driver
- add spinlock to protect tx_buf and ex_buf
- change exported APIs for usb-ljca driver
- unify prefix for structures and functions for i2c-ljca driver
- unify prefix for structures and functions for spi-ljca driver
- unify prefix for structures and functions for gpio-ljca driver
- update gpio-ljca, i2c-ljca and spi-ljca drivers according to usb-ljca's changes
Wentong Wu (4):
usb: Add support for Intel LJCA device
i2c: Add support for Intel LJCA USB I2C driver
spi: Add support for Intel LJCA USB SPI driver
gpio: update Intel LJCA USB GPIO driver
