Subject: [PATCH v20 0/4] Add Intel LJCA device driver
Date: Mon, 9 Oct 2023 14:33:21 +0800 [thread overview]
Message-ID: <1696833205-16716-1-git-send-email-wentong.wu@intel.com> (raw)
Add driver for Intel La Jolla Cove Adapter (LJCA) device. This
IO-expander adds additional functions to the host system with
host USB interface, such as GPIO, I2C and SPI. This patch set
adds four drivers to support this device: a USB device driver,
a GPIO chip driver, a I2C controller driver and a SPI controller
driver.
---
v20:
- add __counted_by attributes for all of [] arrays
- use proper kernel doc for ljca_adapter structure
- re-structure ljca_recv function to make it more clear
- remove all of scoped_guard
- check return value of usb_autopm_get_interface()
- re-structure ljca_enumerate_clients() to handle error correctly
- add comment for 'uid = "0";' in ljca_match_device_ids()
- change the parameters' type of ljca_send() to u8
v17 - v19:
- rebase patch set on top of Linus' master branch (57d88e8a5974644039fbc47806bac7bb12025636)
- change valid_pins type to __le32 and access valid_pins with get_unaligned_le32
- remove COMPILE_TEST for USB_LJCA Kconfig
v16:
- drop all void * and use real types in the exported apis and internal ljca_send()
- remove #ifdef in usb-ljca.c file
- add documentation in ljca.h for the public structures
- add error message in ljca_handle_cmd_ack() if error happens and remove blank line
- use the functionality in cleanup.h for spinlock to make function much simpler
- change the type of ex_buf in struct ljca_adapter to u8 *
v14 - v15:
- enhance disconnect() of usb-ljca driver
- change memchr to strchr in ljca_match_device_ids() of usb-ljca driver
- 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
- avoid err printing because of calling usb_kill_urb when attempts to resubmit the rx urb
v10 - v12:
- 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
- remove ljca_i2c_format_slave_addr
- remove memset before write write w_packet for i2c driver
- 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
