Subject: [PATCH v2 0/4] clk_phase error caching problems
Date: Wed,  5 Feb 2020 15:27:58 -0800	[thread overview]
Message-ID: <20200205232802.29184-1-sboyd@kernel.org> (raw)

This patch series is a follow up to[1] which I sent out a few months
ago. We no longer cache the clk phase if it's an error value, so that
things like debugfs don't return us nonsense values for the phase.

Futhermore, the last patch fixes up the locking so that debugfs code
can avoid doing a recursive prepare lock because we know what we're
doing in that case. While we get some more functions, we avoid taking
the lock again.

Changes from v1:
 * A pile of new patches
 * Rebased to clk-next
 * New patch to bail out of registration if getting the phase fails

Stephen Boyd (4):
  clk: Don't cache errors from clk_ops::get_phase()
  clk: Use 'parent' to shorten lines in __clk_core_init()
  clk: Move rate and accuracy recalc to mostly consumer APIs
  clk: Bail out when calculating phase fails during clk registration
