Subject: [PATCH] SQUASH: dts: Fix firmware clocks support
|
|
|
|
Commit [1] touched a lot of files and still missed some platforms.
|
|
In particular, Pi 2 was left with no clock scaling. Simplify the
|
|
firmware clocks DTS support and extend it to all platforms that
|
|
use the raspberrypi-cpufreq driver.
