Is this property needed? If it's the default assumption it would be
nice
to omit it so that we don't have to think about it.
This property is needed during panel probe. If this is not mentioned
here,
mipi_dsi_attach() will fail during panel probe. In dsi_host.c,
dsi_host_attach()
fails since dsi lanes are greater than msm_host lanes. msm_host lanes
are updated
as part of dsi_host_parse_dt. If we dont provide data-lanes in dt, it'll
have default
value and fail in dsi_host_attach().

Curious how this works. It looks like PMIC GPIOS are expecting the node
to look like:
disp_pins: disp-pins {
pinconf {
pins = "gpio3";
function = PMIC_GPIO_FUNC_FUNC1;
qcom,drive-strength = <PMIC_GPIO_STRENGTH_MED>;
power-source = <PM6150_GPIO_VPH>;
bias-disable;
output-low;
};
but this doesn't use the macros or the subnode for pinconf. Why? Also,
the PM6150_GPIO_VPH macro doesn't exist.
We are discussing with PMIC team to have that macro in the header file.
Will add other macros as part of next version.
