Subject: [PATCH 0/3] clk: keystone: sci-clk: perf improvements
Date: Fri, 12 Apr 2019 21:22:19 +0300	[thread overview]
Message-ID: <1555093342-428-1-git-send-email-t-kristo@ti.com> (raw)

Hi,

After some thinking, I decided to switch the clock scan method for
the sci-clk completely over to DT based scan. For example, on am65xx,
the boot time improvement for the clock probe is from 398ms down to
7.3ms. I retained the full firmware scan code behind a separate
Kconfig option; this can be useful for some debugging purposes if
someone needs to see all the clocks in a device.

Also, added patch #1 for cropping down the registered clock names,
currently they are pretty long forms containing the full interconnect
node paths, which makes the debugfs sort of un-usable.

-Tero
