Signed-off-by: Linus Walleij Reviewed-by: Laurent Pinchart --- ChangeLog v1->v2: - Write that these bridges are non-programmable rather than discrete, as that reflects the name of the bridge being "dumb". Discrete is wrong as it has a specific electronic meaning, as in "non-integrated" and this is integrated. --- drivers/gpu/drm/bridge/Kconfig | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/bridge/Kconfig b/drivers/gpu/drm/bridge/Kconfig index 3b99d5a06c16..e1ab948707a0 100644 --- a/drivers/gpu/drm/bridge/Kconfig +++ b/drivers/gpu/drm/bridge/Kconfig @@ -30,7 +30,8 @@ config DRM_DUMB_VGA_DAC depends on OF select DRM_KMS_HELPER help - Support for RGB to VGA DAC based bridges + Support for non-programmable RGB to VGA DAC based bridges + such as ADI ADV7123 or TI THS8134 and THS8135. config DRM_LVDS_ENCODER tristate "Transparent parallel to LVDS encoder support"
