Subject: [PATCH v5 0/3] WCH CH341 GPIO and SPI support
Date: Thu, 31 Mar 2022 21:33:03 -0500 [thread overview]
Message-ID: <20220401023306.79532-1-frank@zago.net> (raw)
The CH341 is a multifunction chip, presenting 3 different USB PID. One
of these functions is for I2C/SPI/GPIO. This new set of drivers will
manage I2C and GPIO.
Changes from v4:
I should have addressed all the comments: rework of the GPIO interrupt
handling code to be more modern, changes in Kconfig wording, some code
cleanup.
Driver was tested again with up to 4 of these devices. No
error seen.
Changes from v3:
- really converted to an MFD driver. Driver is now split into 3
modules (MFD+I2C+GPIO).
- minor code cleanups
Changes from v2:
- bug fixes
- more robust USB enumeration
- Changed to an MFD driver as suggested

mfd: ch341: add core driver for the WCH CH341 in I2C/SPI/GPIO mode
gpio: ch341: add GPIO MFD cell driver for the CH341
i2c: ch341: add I2C MFD cell driver for the CH341
