When the LCD has not been turned on by the firmware/GOP, because e.g. the device was booted with an external monitor connected over HDMI, we should not turn on the panel-enable GPIO when we request it. Turning on the panel-enable GPIO when we request it, means we turn it on too early in the init-sequence, which causes some panels to not correctly light up. This commits adds a panel_is_on parameter to intel_dsi_vbt_gpio_init() and makes intel_dsi_vbt_gpio_init() set the initial GPIO value accordingly. This fixes the panel not lighting up on a Thundersoft TST168 tablet when booted with an external monitor connected over HDMI. Changes in v2: - Call intel_dsi_get_hw_state() to check if the panel is on instead of relying on the current_mode pointer Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191216205122.1850923-4-hdegoede@redhat.com |
