      ASoC: Tegra I2S: Remove dependency on pdev->id · d4a2eca7
      Stephen Warren 提交于
      When devices are instantiated from device-tree, pdev->id is set to -1.
      Rework the driver so it doesn't depend on the ID.
      
      Tegra I2S instantiated from board files are configured with pdev
      name "tegra-i2s" and ID 0 or 1. The driver core then names the
      device "tegra-i2s.0" or "tegra-i2s.1". This is not changing.
      
      When a device is instantiated from device-tree, it will have
      pdev->name="" and pdev->id=-1. For this reason, the pdev->id value is
      not something we can rely on.
      
      This patch doesn't actually change any names though:
      
      When a device is instantiated from device-tree, the overall device name
      will be "${unit_address}.${node_name}". This causes issues such as
      clk_get() failures due to lack of a device-name match. To solve that,
      AUXDATA was invented, to force a specific device name, thus allowing
      dev_name() to return the same as the non-device-tree case. Tegra
      currently uses AUXDATA for the I2S controllers. Eventually, AUXDATA will
      go away, most likely replaced by phandle-based references within the
      device tree.
