      ASoC: fsl_ssi: use flat regmap cache · bfcf928d
      由 Marek Vasut 提交于 
      Same as commit ce492b3b
Subject: drm/fsl-dcu: use flat regmap cache

Using flat regmap cache instead of RB-tree to avoid the following
lockdep warning on driver load:
WARNING: CPU: 0 PID: 1 at kernel/locking/lockdep.c:2871 lockdep_trace_alloc+0x104/0x128
DEBUG_LOCKS_WARN_ON(irqs_disabled_flags(flags))

The RB-tree regmap cache needs to allocate new space on first
writes. However, allocations in an atomic context (e.g. when a
spinlock is held) are not allowed. The function regmap_write
calls map->lock, which acquires a spinlock in the fast_io case.
Since the driver uses MMIO, the regmap bus of type regmap_mmio
is being used which has fast_io set to true.

      ASoC: rockchip: correct the spdif clk · 46dd2e28
      由 Chris Zhong 提交于 
      The spdif mclk should be 128 times of sample rate, and there is a
internal divider, the real rate of spdif mclk is mclk / (div + 1).
Hence, the original driver always get the good frequency for
48000/96000/44100/192000. But for 32000, the mclk is incorrect,
it should be 32000*128, but get 48000*128. Do not use the internal
divider here, just set all mclk to 128 * sample rate directly.
