# Currently, the megi kernel is the most up-to-date pinephone pro kernel. As postmarketOS doesn't want to use the Megi kernel directly, we can strip the Megi kernel down to it's essentials by doing the following:
|
|
#
|
|
# git reset --hard v7.0
|
|
# git merge megi/fusb302-7.0 megi/imx258-7.0 megi/rk818-7.0 megi/rt5640-7.0 megi/rk3399-typec-7.0 megi/typec-extcon-7.0 megi/tcpm-7.0 megi/arasan-7.0 megi/ppp-7.0

# git cherry-pick ebc624f4 # `arm64: dts: rockchip: rk3399-s: Add DMC table `
|

# git rebase v7.0

# Subject: [PATCH] arm64: dts: rk3399-pinephone-pro: Keep modem regulators always-on
|
|
#
|
|
# The vcc_4g and vcc_4g_5v regulators power the EG25 modem. Mark them
|
|
# always-on so the modem is powered at boot when using eg25-manager.
