We need to be able to get the connector out of a dumb VGA for the PL111 driver. This is because we are using the connector in the driver when initializing the display pipe.
Signed-off-by: Linus Walleij linus.walleij@linaro.org --- This is a bit ugly but not uglier than how we are reaching into the connector of the panels in several drivers. I don't know any better idea, advice welcome. --- drivers/gpu/drm/bridge/dumb-vga-dac.c | 7 +++++++ include/drm/dumb_vga_dac.h | 9 +++++++++ 2 files changed, 16 insertions(+) create mode 100644 include/drm/dumb_vga_dac.h
