To allow the driver to have a per Solomon display controller modesetting pipeline and support aother controller families besides SSD130x. Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> --- Changes in v3: - Drop the per controller family functions table (Thomas Zimmermann). Changes in v2: - Squash patch that uses drm_format_info_min_pitch() to calculate dest_pitch with the following patch (Geert Uytterhoeven). - Store ssd13xx_family_funcs[SSD130X_FAMILY] in struct ssd130x_deviceinfo (Geert Uytterhoeven). - Don't mix switch (family_id) and ssd13xx_funcs[family_id] (Geert Uytterhoeven). - Replace switch (family_id) by an .set_buffer_sizes (Geert Uytterhoeven). - Move the rect alignment to a per chip family function (Geert Uytterhoeven). drivers/gpu/drm/solomon/ssd130x-i2c.c | 1 + drivers/gpu/drm/solomon/ssd130x-spi.c | 2 ++ drivers/gpu/drm/solomon/ssd130x.c | 5 +++++ drivers/gpu/drm/solomon/ssd130x.h | 7 +++++++ 4 files changed, 15 insertions(+)
