      ASoC: fix ES8328_I2C/SPI dependencies · 245c5c7b
      由 Arnd Bergmann 提交于 
      The two front-ends to the codec can now be selected individually, but fail to
build when the bus support is missing:

sound/built-in.o: In function `es8328_spi_probe':
es8328-spi.c:(.text+0x125854): undefined reference to `__devm_regmap_init_spi'
sound/built-in.o: In function `es8328_spi_driver_init':
es8328-spi.c:(.init.text+0x3589): undefined reference to `__spi_register_driver'

Related to this, the added dependency on SND_SOC_ES8328 breaks:

warning: (SND_SOC_ALL_CODECS) selects SND_SOC_ES8328_I2C which has unmet direct dependencies (SOUND && !M68K && !UML && SND && SND_SOC && SND_SOC_ES8328 && I2C)

This adds the respective Kconfig dependencies and changes SND_SOC_ES8328 to a hidden
symbol that is selected implicitly by the two more specific options, as we do for
some other codecs. We have to remove the 'depends on' for SND_SOC_IMX_ES8328 in the
same step to avoid a recursive dependency.

Fixes: aa00f2c8 ("ASoC: Allow to select ES8328_I2C and ES8328_SPI directly")

      ASoC: fsl_ssi: set fifo watermark to more reliable value · 4ee437fb
      由 Caleb Crome 提交于 
      The fsl_ssi fifo watermark is by default set to 2 free spaces (i.e.
activate DMA on FIFO when only 2 spaces are left.)  This means the
DMA must service the fifo within 2 audio samples, which is just not
enough time  for many use cases with high data rate.  In many
configurations the audio channel slips (causing l/r swap in stereo
configurations, or channel slipping in multi-channel configurations).

This patch gives more breathing room and allows the SSI to operate
reliably by changing the fifio refill watermark to 8.

There is no change in behavior for older chips (with an 8-deep fifo).
Only the newer chips with a 15-deep fifo get the new behavior. I
suspect a new fifo depth setting could be optimized on the older
chips too, but I have not tested.

      ASoC: fsl_ssi: Remove .num_reg_defaults_raw from regmap_config · 7de2763d
      由 Marek Vasut 提交于 
      This driver provides no .reg_defaults_raw in regmap_config, so
the .num_reg_defaults_raw is useless, and, in fact harmful. It
triggers kernel crash in regmap_init which tries to access the
register defaults.

      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: fsl_ssi: Fix number of words per frame for I2S-slave mode · 4f14f5c1
      由 Alexander Shiyan 提交于 
      The i.MX51 datasheet says:
Chapter 56.1.2.4 I2S Mode
...
When I2S modes are entered (I2S master (01) or I2S slave (10)),
the following settings are recommended:
...
- TX Frame Rate should be 2 i.e. (STCCR[12:8] = 1)
- RX Frame Rate should be 2 i.e. (SRCCR[12:8] = 1)

Chapter 56.3.3.12 SSI Transmit and Receive Clock Control Registers (STCCR & SRCCR)
...
Bits 12-8 DC4-DC0
Frame Rate Divider Control. These bits are used to control the divide ratio
for the programmable frame rate dividers. The divide ratio works on the word
clock. In Normal mode, this ratio determines the word transfer rate.
In Network mode, this ratio sets the number of words per frame. The divide
ratio ranges from 1 to 32 in Normal mode and from 2 to 32 in Network mode.
In Normal mode, a divide ratio of 1 (DC=00000) provides continuous periodic
data word transfer. A bit-length frame sync must be used in this case.

Function fsl_ssi_hw_params() setup Normal mode for MONO output,
so with DC=0, SSI enters to continuous periodic data word transfer.
To fix this, setup DC for any I2S mode.
Patch has tested on custom board based on Digi CCMX-51 module (i.MX51).
