Subject: [PATCH v5 2/7] platform/x86: amd-pmc: Fix SMU firmware reporting mechanism
Date: Tue, 29 Jun 2021 14:17:58 +0530	[thread overview]
Message-ID: <20210629084803.248498-3-Shyam-sundar.S-k@amd.com> (raw)
In-Reply-To: <20210629084803.248498-1-Shyam-sundar.S-k@amd.com>

It was lately understood that the current mechanism available in the
driver to get SMU firmware info works only on internal SMU builds and
there is a separate way to get all the SMU logging counters (addressed
in the next patch). Hence remove all the smu info shown via debugfs as it
is no more useful.

Fixes: 156ec4731cb2 ("platform/x86: amd-pmc: Add AMD platform support for S2Idle")
