ENGR00318895-8 mtd: fsl-quadspi: add the DDR quad read support for Spansion NOR
Add the DDR quad read support for the fsl-quadspi driver.
Check the "spi-nor,ddr-quad-read-dummy" DT property, if the DT node is exit,
it means we could enable the DDR quad read.
(1) Test this patch with imx6sx-sdb board (Spansion s25fl128s)
The clock rate is 66MHz.
(2) The information of NOR flash:
-----------------------------------------------
root@imx6qdlsolo:~# mtdinfo /dev/mtd0
mtd0
Name: 21e4000.qspi
Type: nor
Eraseblock size: 65536 bytes, 64.0 KiB
Amount of eraseblocks: 256 (16777216 bytes, 16.0 MiB)
Minimum input/output unit size: 1 byte
Sub-page size: 1 byte
Character device major/minor: 90:0
Bad blocks are allowed: false
Device is writable: true
-----------------------------------------------
(3) Test this patch set with UBIFS & bonnie++:
-----------------------------------------------
ubiattach /dev/ubi_ctrl -m 0
ubimkvol /dev/ubi0 -N test -m
mount -t ubifs ubi0:test tmp
bonnie++ -d tmp -u 0 -s 10 -r 5
-----------------------------------------------
[3] add set_ddr_quad_mode() to initialize for the DDR quad read.
Currently it only works for Spansion NOR.
[3] about the dummy cycles.
We set the dummy with 8 for DDR quad read by default.
The m25p80.c can not support the DDR quad read, but the SPI NOR controller
can set the dummy value in its child DT node, and the SPI NOR framework
can parse it out.
ENGR00318895-3 mtd: spi-nor: add a new field for spi_nor{}
We need the SPI NOR child node to store some specific features, such as the
dummy cycles for the DDR Quad read.
But now, we only have the @dev field in the spi_nor{}. The @dev may points to a
spi_device{} for m25p80, while it may points to a platform_deivice{} for the
SPI NOR controller, such as fsl_quadspi.c.
It is not convenient for us to get come information from the SPI NOR flash.
This patch adds a new field @np to spi_nor{}, it points to the child node for
the SPI NOR flash.
ENGR00318895-1 mtd: spi-nor: read 6 bytes for the ID
Currently, we read 5 bytes for ID, but s25fl128s has the same ext_id(0x4d01)
with s25fl129p1. The s25fl128s can support the DDR Quad read, while s25fl129p1
does not. So we have to distinguish the two NOR flashs.
This patch reads out 6 bytes for the ID, and use the 6 bytes ID to search the
right flash_info.
The detail of the patch is:
[1] change the "ext_id" from u16 to u32.
We can store two bytes or three bytes with the @ext_id now.
[2] search the right flash_info with the 6byte ID and the new @ext_id.
We use "matched" variable to track the legacy two bytes @ext_id.
If the flash_info's @ext_id is three bytes, we will use the
sixth byte of the ID to check it.
[3] add the new item to spi_nor_ids for s25fl128s.

The baudclock may be used and set by different streams.
Allow only the first stream to set the bitclock rate. Other streams have
to try to get to the correct rate without modifying the bitclock rate
using the SSI internal clock modifiers.
The variable baudclk_streams is introduced to keep track of the active
streams that are using the baudclock. This way we know if the baudclock
may be set and whether we may enable/disable the clock.
baudclock enable/disable is moved to hw_params()/hw_free(). This way we can
keep track of the baudclock in those two functions and avoid a running
clock while it is not used. As hw_params()/hw_free() may be called
multiple times for the same stream, we have to use baudclk_streams

ASoC: fsl: select SND_SOC_IMX_PCM_DMA where needed
Since commit 204dec93eaa "ASoC: fsl: Allow to select individual common
options", it is possible to enable SND_SOC_FSL_SSI and SND_SOC_FSL_SPDIF
manually, either as loadable modules or built-in. This unfortunately
leads to a link error if one or both of them are built-in, while
the imx-pcm-dma framework is a loadable module:
sound/built-in.o: In function `fsl_ssi_probe':
:(.text+0x51fb8): undefined reference to `imx_pcm_dma_init'
sound/built-in.o: In function `fsl_spdif_probe':
:(.text+0x52e20): undefined reference to `imx_pcm_dma_init'
This changes Kconfig to prevent this case by using 'select' to turn
on the imx-pcm-dma code from both drivers. For consistency, we also
turn on the imx-pcm-fiq code, which is an alternative to the dma
implementation.
Note that imx-pcm-fiq is platform dependent, so we must not enable
that unless we are building a kernel for i.MX. Note also the
"if SND_IMX_SOC != n" syntax as opposed to the normal "if SND_IMX_SOC".
This is needed to avoid turning on the options as 'm' if 'SND_IMX_SOC'
is a module.

ASoC: fsl_sai: Fix buggy configurations in trigger()
The current trigger() has two crucial problems:
1) The DMA request enabling operations (FSL_SAI_CSR_FRDE) for Tx and Rx are
now totally exclusive: It would fail to run simultaneous Tx-Rx cases.
2) The TERE disabling operation depends on an incorrect condition -- active
reference count that only gets increased in snd_pcm_open() and decreased
in snd_pcm_close(): The TERE would never get cleared.
So this patch overwrites the trigger function by following these rules:
A) We continue to support tx-async-while-rx-sync-to-tx case alone, which's
originally limited by this fsl_sai driver, but we make the code easy to
modify for the further support of the opposite case.
B) We enable both TE and RE for PLAYBACK stream or CAPTURE stream but only
enabling the DMA request bit (FSL_SAI_CSR_FRDE) of the current direction
due to the requirement of SAI -- For tx-async-while-rx-sync-to-tx case,
the receiver is enabled only when both the transmitter and receiver are
enabled.

rtd->codec does not necessarily point to the CODEC instance for which the
callback was called (e.g. for CODEC<->CODEC or multi-CODEC links). Use
dai->codec instead.

ASoC: cs42xx8: Check return value of regmap_read and report correct chipid value
Fix checking return value of regmap_read().
Also fix reporting the chip_id value. CS42XX8_CHIPID_CHIP_ID_MASK is 0xF0,
so the chip_id value is (val & CS42XX8_CHIPID_CHIP_ID_MASK) >> 4).

ASoC: cs42xx8: Add codec driver support for CS42448/CS42888
This patch adds support for the Cirrus Logic CS42448/CS42888 Audio CODEC that
has six/four 24-bit AD and eight 24-bit DA converters.
[ CS42448/CS42888 supports both I2C and SPI control ports. As initial patch,
this patch only adds the support for I2C. ]

ASoC: core: Add signed register volume control logic
Some codecs use signed volume control representation with non standard
register sizes, e.g. 6 or 7 bit signed integers.
This patch adds generic signed register volume control logic to
soc-core. Instead of a fixed width signed register control, this
implementation uses a 'min' value and the signed bit location to translate
it to an absolute volume. Using the 'sign_bit' we can calculate a
correct mask for the register values and translate it back into signed
integers of standard size.
