      ASoC: Clean up error handling in MPC5200 DMA setup · 33d7f778
      Julia Lawall 提交于
      Error handling code following a kzalloc should free the allocated data.
      Error handling code following an ioremap should iounmap the allocated data.

      ASoC: Allow per-route connectedness checks for supplies · 215edda3
      Mark Brown 提交于
      Some chips with complex internal supply (particularly clocking)
      arragements may have multiple options for some of the supply
      connections. Since these don't affect user-visible audio routing
      the expectation would be that they would be managed automatically
      by one of the drivers.
      
      Support these users by allowing routes to have a connected function
      which is queried before the connectedness of the path is checked as
      normal. Currently this is only done for supplies, other widgets
      could be supported but are not currently since the expectation for
      them is that audio routing will be under the control of userspace.

      ASoC: au1x: PSC-AC97 bugfixes · cdc65fbe
      Manuel Lauss 提交于
      This patch fixes the following bugs:
      
      - only reprogram bitdepth if it has changed since last call to hw_params.
      - add locking inside ac97_read/write functions:
        When reprogramming sample depth, the ac97 unit has to be disabled,
        which should not be done in the middle of codec register accesses.
      
      - retry timed-out codec register accesses.
      
      - wait for status bits to set/clear when starting/stopping various
        functional blocks; very important after reenabling AC97 unit else
        sound may be distorted (e.g. high-pitch noise in 1kHz sine wave).
      
      - clear fifos before/after starting/stopping RX/TX.
      
      - longer timeouts waiting for PSC/AC97 ready after cold reset
        with certain codecs this can take ridiculous amounts of time.
      
      Run-tested on various Au1200 platforms with various codecs.
