From: Suman Anna Date: Tue, 10 Mar 2020 21:05:53 +0000 (-0500) Subject: remoteproc: k3-dsp: Fix unbalanced state machine in k3_dsp_start X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=0020003ef3aac0d56b0d1b26c1dcace4b7d1ae6f;p=u-boot.git remoteproc: k3-dsp: Fix unbalanced state machine in k3_dsp_start The global module reset is deasserted through the ti_sci_power_domain_on() call in k3_dsp_start(), but is not asserted back if the local module reset fails. Fix this. While at this, remove the stale comment about assigned-clock-rates that seems to have been copied from the K3 ARM64 Remoteproc driver.
