[PATCH] ARM: dts: n900: set charge current limit to 950mA

[PATCH] ARM: dts: n900: set charge current limit to 950mA

[Sicelo A. Mhlongo]

From: Arthur Demchenkov <spinal.by@gmail.com>

The vendor kernel used 950mA as the default. The same value works fine on
the mainline Linux kernel, and has been tested extensively under Maemo
Leste [1] and postmarketOS, who have been using it for a number of years.

Makes sense to me. At -rc6 I'll likely wait until v6.9-rc1 before applying
new patches. If this is needed as a fix before that, then please let me
know.

Thank you. It can wait for v6.9-rc1, since using 650mA does not cause a
major usability issue.

Thanks applying into omap-for-v6.10/dt.
