imx6sl lcdif - disable LCD_RESET?

Hi,

I have a display driver working in u-boot which sets up my display over spi ready for RGB interface mode later on.

However, when kernel boots, it uses &lcdif and mxsfb driver which sends reset signal to the display.

Is there a way to disable the reset in kernel?

I have tried setting mux of pin as follows in dts:

MX6SL_PAD_LCD_RESET__GPIO2_IO19 0x80000000

But still the mxsfb driver toggles the reset line.

Thanks,

Hi nigel

could you try to set reset line as input in uboot after display was

configured, 0x80000000 sets iomux untouched in linux.

Best regards
igor
