drm/ssd130x: ensure ssd132x pitch is correct

2025-01-16T09:48:47Z

The bounding rectangle is adjusted to ensure it aligns to SSD132X_SEGMENT_WIDTH, which may adjust the pitch. Calculate the pitch after aligning the left and right edge.

drm/ssd130x: fix ssd132x encoding

2025-01-16T09:48:46Z

The ssd132x buffer is encoded one pixel per nibble, with two pixels in each byte. When encoding an 8-bit greyscale input, take the top 4-bits as the value and ensure the two pixels are distinct and do not overwrite each other.

drm/ssd130x: Set SPI .id_table to prevent an SPI core warning

2025-01-08T11:10:37Z

The only reason for the ssd130x-spi driver to have an spi_device_id table is that the SPI core always reports an "spi:" MODALIAS, even when the SPI device has been registered via a Device Tree Blob. Without spi_device_id table information in the module's metadata, module autoloading would not work because there won't be an alias that matches the MODALIAS reported by the SPI core. This spi_device_id table is not needed for device matching though, since the of_device_id table is always used in this case. For this reason, the struct spi_driver .id_table member is currently not set in the SPI driver. Because the spi_device_id table is always required for module autoloading, the SPI core checks during driver registration that both an of_device_id table and a spi_device_id table are present and that they contain the same entries for all the SPI devices. Not setting the .id_table member in the driver then confuses the core and leads to the following warning when the ssd130x-spi driver is registered: [ 41.091198] SPI driver ssd130x-spi has no spi_device_id for sinowealth,sh1106 [ 41.098614] SPI driver ssd130x-spi has no spi_device_id for solomon,ssd1305 [ 41.105862] SPI driver ssd130x-spi has no spi_device_id for solomon,ssd1306 [ 41.113062] SPI driver ssd130x-spi has no spi_device_id for solomon,ssd1307 [ 41.120247] SPI driver ssd130x-spi has no spi_device_id for solomon,ssd1309 [ 41.127449] SPI driver ssd130x-spi has no spi_device_id for solomon,ssd1322 [ 41.134627] SPI driver ssd130x-spi has no spi_device_id for solomon,ssd1325 [ 41.141784] SPI driver ssd130x-spi has no spi_device_id for solomon,ssd1327 [ 41.149021] SPI driver ssd130x-spi has no spi_device_id for solomon,ssd1331 To prevent the warning, set the .id_table even though it's not necessary. Since the check is done even for built-in drivers, drop the condition to only define the ID table when the driver is built as a module. Finally, rename the variable to use the "_spi_id" convention used for ID tables.

drm: remove driver date from struct drm_driver and all drivers
