Re: [PATCH v2 01/10] dt-bindings: display: bridge: tc358775: make stby gpio and vdd supplies optional
For a normal operation, the vdd supplies nor the stby GPIO is needed. There are boards, where these voltages are statically enabled during board power-up. This means supply is still required. You mean using fixed-regulator? I didn't consider that. But yes, you're right. -michael

[PATCH v2 01/10] dt-bindings: display: bridge: tc358775: make stby gpio and vdd supplies optional
From: Michael Walle For a normal operation, the vdd supplies nor the stby GPIO is needed. There are boards, where these voltages are statically enabled during board power-up. The reset pin is required because once the PPI (PHY protocol interface) is started, it can only be stopped by asserting the reset pin.
