[PATCH 1/1] drm/panel: st7703: Pick different reset sequence

2023-02-12 Thread Frank Oltmanns
From: Ondrej Jirman Switching to a different reset sequence, enabling IOVCC before enabling VCC. There also needs to be a delay after enabling the supplies and before deasserting the reset. The datasheet specifies 1ms after the supplies reach the required voltage. Use 10-20ms to also give the po
