From 0438a0a181675cb5d149184d8a6e50678cbc6d15 Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Tue, 10 Mar 2020 18:34:54 -0500 Subject: [PATCH] remoteproc: k3-r5: Fix rproc init failure for Main R5FSS0 The Main R5FSS0 cluster is also enabled to probe the R5F remoteproc driver within R5 SPL for booting the Core0 very early. This results in a ti_sci_power_domain_on failure during the probe from the A72 U-Boot when "rproc init" is executed at U-Boot prompt, and doesn't enumerate all the rproc devices. Fix this by suppressing the power_domain_on altogether using the flag DM_FLAG_DEFAULT_PD_CTRL_OFF added in commit af94ad418dc7 ("dm: core: Allow for not controlling the power-domain by DM framework").
