Subject: [PATCH v2 0/5] drm/solomon: Add SSD130x OLED displays SPI support
Date: Mon, 11 Apr 2022 23:12:38 +0200 [thread overview]
Message-ID: <20220411211243.11121-1-javierm@redhat.com> (raw)
Hello,
This series adds a ssd130x-spi driver that provides a 4-wire SPI transport
support for SSD130x OLED controllers that can be accessed through a SPI.
The driver is quite similar to existing ssd130x-i2c driver that is used by
I2C controllers, but there is a difference in the protocol used by SSD130x
depending on the transport used. The details are in patch #4 description.
Patch #1 just makes the current ssd130x-i2c compatible strings in the DT
binding to be deprecated, and add new ones that don't have an "fb-i2c".
Patch #2 extends the DT binding with the properties needed to support SPI.
Patch #3 adds the new compatible strings to the OF device ID table in the
ssd130x-i2c DRM driver and deprecate the old ones.
Patch #4 moves the device info for the different SSD130x variants from
the ssd130x-i2c transport driver to the ssd130x core driver.
Finally patch #5 adds the ssd130x-spi DRM driver for the OLED controllers
that come with a 4-wire SPI interface, instead of an I2C interface.
This is a v2 that addresses the issues pointed out in v1.
Best regards,
Javier
Changes in v2:
- Drop the -i2c suffixes from the compatible strings too (Geert Uytterhoeven).
- Don't add compatible strings with an "-spi" suffix (Geert Uytterhoeven).
- Drop ssd13x_variant_to_info() and just use the array index (Neil Armstrong).
- Add Mark Brown's Acked-by tag to all patches.
