[PATCH 6.7 068/346] ARM: dts: samsung: exynos4210-i9100: Unconditionally enable LDO12

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Paul Cercueil <paul@xxxxxxxxxxxxxxx>

commit 84228d5e29dbc7a6be51e221000e1d122125826c upstream.

The kernel hangs for a good 12 seconds without any info being printed to
dmesg, very early in the boot process, if this regulator is not enabled.

Force-enable it to work around this issue, until we know more about the
underlying problem.
