Subject: [PATCH 2/3] ram: rk3399: Fix faulty frequency change reports
Date: Thu, 11 Aug 2022 08:58:47 +0100 [thread overview]
Message-ID: <20220811075848.1791050-3-lee@kernel.org> (raw)
In-Reply-To: <20220811075848.1791050-1-lee@kernel.org>
Frequency changes to 400MHz are presently reported as:
lpddr4_set_rate_0: change freq to 400000000 mhz 0, 1
This is obviously wrong by 6 orders of magnitude.
Ensure frequency changes are reported accurately.
