+Subject: Eliminate Odroid HC4 power glitches during boot.
+
+Fix issue with Odroid HC4 (and all meson-sm1-odroid) DTS that causes
+regulator power to momentarily glitch OFF-ON during boot.  Add
+regulator-boot-on to all regulator-fixed and regulator-gpio entries
+that (1) define a gpio AND (2) define regulator-always-on.
+
+U-boot powers on devices necessary for boot then hands off the DTB to
+the kernel.  During probe, linux drivers/regulator/fixed.c and
+gpio-regulator.c both first set the regulator control gpio (that U-boot
+already turned ON) to default OFF before then setting it to the defined
+(ON) state. This glitches the power to the affected devices, unless
+regulator-boot-on is specified with it.  In fact, U-boot has the same
+behavior.  So, during reboot, a power glitch can actually happen twice:
+once when U-boot reads the DTB and probes the gpio and again when the
+kernel reads the DTB and probes the gpio.
+
+Problem this fixes: On the Odroid HC4, power to the SATA ports glitches
+during boot and causes some HDDs to do emergency head retract, which
+should be avoided.  On the HC4, power glitches to the SD card, USB,
+SATA, and HDMI interfaces during boot.  These are all boot devices.
+A power glitch can potentially cause a problem for any sensitive devices
+during boot.
+
+NOTE: This is not limited to just the HC4, likely an issue with ALL DTS
+with regulator-fixed or regulator-gpio entries that (1) define a gpio
+AND (2) define regulator-always-on.  All such entries should also
+include regulator-boot-on in order to avoid potential power glitches.
+At worst, adding regulator-boot-on in such cases is harmless because of
+regulator-always-on, and, at best, it eliminates detrimental power
+glitches during boot.  So, this is best-practice.
