From 88358069ed07f16a0aab0764ed1337e540006e29 Mon Sep 17 00:00:00 2001
From: Phil Elwell <phil@raspberrypi.com>
Date: Wed, 4 Nov 2020 11:25:02 +0000
Subject: [PATCH] overlays: Deprecate and delete the sdtweak overlay
The sdtweak overlay has been superseded by the board-specific
sd_* parameters such as sd_poll_once, sd_overclock etc.
For example, replace:
dtoverlay=sdtweak,poll_once
with:
dtparam=sd_poll_once
Signed-off-by: Phil Elwell <phil@raspberrypi.com>
