From 61be023775ab1ccef072bd8116f0ccf740bf8708 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Sun, 14 Mar 2021 16:47:46 +0100 Subject: v7a: barebox update 2020.09.0 -> 2021.02.0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit One new patch is required to fix a regression for USB on rpi3. Also USB on rpi3 requires CONFIG_USB_NOP_XCEIV=y now which is enabled in the rpi2 config now. For the beaglebone two patches are added fixing a regression related to a dts sync from upstream. All three patches were already sent to the barebox mailing list.

These are buses that reference a clock +or a power domain that needs to be enabled in order to use devices on it. + +As we didn't yet support this binding, this broke the Beaglebone +and all other am33xx board since v2021.02.0. + +Fix this by adding simple-pm-bus to the of_default_bus_match_table. +Note that this is only an adequate solution for when the power domain +and clocks referenced are already enabled prior to barebox startup. + +For all other cases, driver support must be available for the clock +and power domains in questions and this driver must be extended to +make use of them.
