Related issue: #1285 (closed)
This merge request contains the following changes:
- Compile pinephone dts with
-@option so that is contains symbols used by DT overlays
- Make U-boot script
boot.scrload an external
user.scrscript, no effect if
user.scris not present
user.scrload and apply the Device Tree Overlay that matches the regulator change of Vccq mod and enables HS200
pinephone-vccq-mod.dtbofiles in a subpackage of
device-pine64-pinephone, that can be installed manually.
This change has no effect on a regular PinePhone pmos installation.
If one performs the eMMC Vccq mod the phone will boot fine but without speed increase.
By installing the package
device-pine64-pinephone-vccq-mod, a Device Tree Overlay is applied at boot and you get double speed from the eMMC (HS200 mode).
The change is persistent for the current pmos installation, and should survive u-boot and kernel updates, but the subpackage has to be installed again after formatting.
I have tested the changes on my modded PinePhone 1.2, it works fine with and without the subpackage installed.
I can provide a guide for the hardware modification in the wiki, pinephone page or dedicated page?.
