[PATCH 1/3] arm64: dts: qcom: sdm845-oneplus: Don't mark ts supply boot-on

[David Heidelberg via B4 Relay]

From: Casey Connolly <casey.connolly@linaro.org>

The touchscreen 1.8v supply doesn't need to be enabled at boot, only
when the driver probes. Remove the regulator-boot-on property.

[David Heidelberg via B4 Relay]

From: Casey Connolly <casey.connolly@linaro.org>

The panel regulator doesn't need to be always on, so remove this
property.

[David Heidelberg via B4 Relay]

From: Casey Connolly <casey.connolly@linaro.org>

This regulator is used only for the display, which is enabled by the
bootloader and left on for continuous splash. Mark it as such.

This is not exactly what this property signifies (although it does
indeed turn the regulator on if it's not)

regulator-boot-on:
  description: bootloader/firmware enabled regulator.
    It's expected that this regulator was left on by the bootloader.
    If the bootloader didn't leave it on then OS should turn it on
    at boot but shouldn't prevent it from being turned off later.
    This property is intended to only be used for regulators where
    software cannot read the state of the regulator.

I only know this works well at current next-202511xx, these patches 
we're also in sdm845-mainline downstream repo, but there was multiple 
different patches and hacks for panels and other stuff present, so it's 
hard for me verify that on clean mainline kernel these will work as 
expected (as older mainline versions also need the panel patched etc.)

If you insist, I can append Fixes against when these properties we're or 
weren't introduced (talking about PATCH 3/3 too).

Fixes != backports
