Subject: [PATCH 0/3] clk: si5351: PLL reset fixes
Date: Sat, 12 Aug 2017 16:23:00 +0200 [thread overview]
Message-ID: <1502547783-24685-1-git-send-email-sergej@taudac.com> (raw)
The Si5351 clock generator has up to 8 output clocks and 2 PLLs. In order
to get a deterministic phase offset relationship between the output clocks,
it is necessary to reset the PLLs is certain scenarios.
This patch-set:
* fixes a regression and adds resetting the PLL before enabling the outputs
* adds a dt-property for enabling/disabling the PLL reset
* adds a debug message for PLL reset (it is helpful during debugging,
probably no longer required?)
Based on clk-next.
Best regards,
Sergej
