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
