Subject: [U-Boot] [PATCH 0/3] Add drive-strength-microamp in Meson pinctrl driver
Date: Tue, 4 Jun 2019 13:53:05 +0200 [thread overview]
Message-ID: <20190604115308.26510-1-glaroque@baylibre.com> (raw)
The purpose of this patchset is to add drive-strength-microamp support in meson pinconf
driver. This is a new feature that was added on the g12a. It is critical for us
to support this since many functions are failing with default pad drive-strength.
The value achievable by the SoC are 500uA, 2500uA, 3000uA and 4000uA and the DT property
'drive-strength-microamp' is expressed in uA.
So this patch add another generic property "drive-strength-microamp". The change to do so
would be minimal and could be benefit to other platforms later on.
it's backport from linux :
