Subject: [PATCH] arm: iproc: Add higher speed configurations
Date: Fri,  4 Jun 2021 14:25:36 +1200	[thread overview]
Message-ID: <20210604022536.29195-1-judge.packham@gmail.com> (raw)

Add support for 1.3GHz, 1.35GHz and 1.4GHz parts. This is based on
equivalent code in Broadcom's LDK 5.0.6.

Signed-off-by: Chris Packham <judge.packham@gmail.com>

---
As Broadcom are currently migrating users to the BCM58525BB1KF14G part
I suspect others may want this. In our case because we wanted to still
run at 1.2GHz we also had to set CONFIG_ARMCLK to 1200.
