Subject: [PATCH v14 0/4] Add Intel LJCA device driver
Date: Mon, 4 Sep 2023 13:44:17 +0800 [thread overview]
Message-ID: <1693806261-12958-1-git-send-email-wentong.wu@intel.com> (raw)
Add driver for Intel La Jolla Cove Adapter (LJCA) device. This
IO-expander expands additional functions to the host system
such as GPIO, I2C and SPI with USB host interface. We add 4
drivers to support this device: a USB driver, a GPIO chip driver,
a I2C controller driver and a SPI controller driver.
---
v14:
- fix build error: implicit declaration of function 'acpi_dev_clear_dependencies'
v13:
- make ljca-usb more robust with the help of Hans de Goede
- call acpi_dev_clear_dependencies() to mark _DEP ACPI dependencies on the I2C controller as satisfied, and patch is from Hans de Goede
v12:
- switch dev_err to dev_dbg for i2c-ljca driver
- avoid err printing because of calling usb_kill_urb when attempts to resubmit the rx urb
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
