Subject: [PATCH v3 0/2] leds: add ktd20xx LED driver support
Date: Mon, 17 Jan 2022 13:47:39 +0100 [thread overview]
Message-ID: <20220117124741.7165-1-fe@dev.tdt.de> (raw)
Introducing the KTD2061/58/59/60 RGB LED drivers. The difference in
these are the address numbers on the I2C bus that the device listens to.
Due to the hardware limitation, we can only set 7 colors and the color
black (LED off) for each LED independently and not the full RGB range.
v1: Initial send
v2: Remove variant 1 from source
v3: Changes requested by Andy Shevchenko added. Thanks for reviewing
- Removing OF dependency
- Add missing includes
- Use device_property_read_u32() instead of fwnode_property_read_u32()
- Use one liner function pattern <test> ? <value-true> : <value-false>
- Remove switch case call for intensity color selection use BIT()
instead
- Remove not needed fwnode_handle_put() in ktd200xx_probe_dt() function
- Use dev_get_drvdata() instead of i2c_get_clientdata() function call
- Use sysfs_emit() function call
- Use kstrtobool() function call
- Remove not needed comma after last array element
- Use dev_err_probe() instead of dev_error() in driver probe function
- Do not use dev_group registration function set .dev_groups directly
into ktd20xx_driver struct.
