1 BE 'big-endian'
2 LE 'little-endian'
+3 Native 'native-endian'
For one device driver, which will run in different scenarios above
on different SoCs using the devicetree, we need one way to simplify
this.
-Required properties:
-- {big,little}-endian: these are boolean properties, if absent
- meaning that the CPU and the Device are in the same endianness mode,
- these properties are for register values and all the buffers only.
+Optional properties:
+- {big,little,native}-endian: these are boolean properties, if absent
+ then the implementation will choose a default based on the device
+ being controlled. These properties are for register values and all
+ the buffers only. Native endian means that the CPU and device have
+ the same endianness.
Examples:
Scenario 1 : CPU in LE mode & device in LE mode.

+Analog Devices ADAU1361/ADAU1461/ADAU1761/ADAU1961/ADAU1381/ADAU1781
+
+Required properties:
+
+ - compatible: Should contain one of the following:
+ "adi,adau1361"
+ "adi,adau1461"
+ "adi,adau1761"
+ "adi,adau1961"
+ "adi,adau1381"
+ "adi,adau1781"
+
+ - reg: The i2c address. Value depends on the state of ADDR0
+ and ADDR1, as wired in hardware.
+
+Examples:
+#include <dt-bindings/sound/adau17x1.h>
+
+ i2c_bus {
+ adau1361@38 {
+ compatible = "adi,adau1761";
+ reg = <0x38>;
+ };
+ };
"fsl,imx-audio-cs42888"
+ "fsl,imx-audio-cs427x"
+ (compatible with CS4271 and CS4272)
+
"fsl,imx-audio-wm8962"
(compatible with Documentation/devicetree/bindings/sound/imx-audio-wm8962.txt)
- audio-asrc : The phandle of ASRC. It can be absent if there's no
need to add ASRC support via DPCM.
+Optional unless SSI is selected as a CPU DAI:
+
+ - mux-int-port : The internal port of the i.MX audio muxer (AUDMUX)
+
+ - mux-ext-port : The external port of the i.MX audio muxer
+
Example:
sound-cs42888 {
compatible = "fsl,imx-audio-cs42888";
--- /dev/null
+max9867 codec
+
+This device supports I2C mode only.
+
+Required properties:
+
+- compatible : "maxim,max9867"
+- reg : The chip select number on the I2C bus
+
+Example:
+
+&i2c {
+ max9867: max9867@0x18 {
+ compatible = "maxim,max9867";
+ reg = <0x18>;
+ };
+};
--- /dev/null
+max98926 audio CODEC
+
+This device supports I2C.
+
+Required properties:
+
+ - compatible : "maxim,max98926"
+
+ - vmon-slot-no : slot number used to send voltage information
+ or in inteleave mode this will be used as
+ interleave slot.
+
+ - imon-slot-no : slot number used to send current information
+
+ - interleave-mode : When using two MAX98926 in a system it is
+ possible to create ADC data that that will
+ overflow the frame size. Digital Audio Interleave
+ mode provides a means to output VMON and IMON data
+ from two devices on a single DOUT line when running
+ smaller frames sizes such as 32 BCLKS per LRCLK or
+ 48 BCLKS per LRCLK.
+
+ - reg : the I2C address of the device for I2C
+
+Example:
+
+codec: max98926@1a {
+ compatible = "maxim,max98926";
+ vmon-slot-no = <0>;
+ imon-slot-no = <2>;
+ reg = <0x1a>;
+};
Texas Instruments pcm179x DT bindings
-This driver supports the SPI bus.
+This driver supports both the I2C and SPI bus.
Required properties:
For required properties on SPI, please consult
Documentation/devicetree/bindings/spi/spi-bus.txt
+Required properties on I2C:
+
+ - reg: the I2C address
+
+
Examples:
codec_spi: 1792a@0 {
spi-max-frequency = <600000>;
};
+ codec_i2c: 1792a@4c {

+ * all knowledge of the configuration in advance. It is given this
+ * information piecemeal by the composite gadget framework after every
+ * SET_CONFIGURATION and SET_INTERFACE. Trying to follow the databook
+ * programming model in this scenario can cause errors. For two

+ *
+ * 1) The databook says to do DEPSTARTCFG for every SET_CONFIGURATION
+ * and SET_INTERFACE (8.1.5). This is incorrect in the scenario of
+ * multiple interfaces.
+ *
+ * 2) The databook does not mention doing more DEPXFERCFG for new
+ * endpoint on alt setting (8.1.6).
+ *
+ * The following simplified method is used instead:
+ *
+ * All hardware endpoints can be assigned a transfer resource and this
+ * setting will stay persistent until either a core reset or
+ * hibernation. So whenever we do a DEPSTARTCFG(0) we can go ahead and
+ * do DEPXFERCFG for every hardware endpoint as well. We are
+ * guaranteed that there are as many transfer resources as endpoints.
+ *
+ * This function is called for each endpoint when it is being enabled
+ * but is triggered only when called for EP0-out, which always happens
+ * first, and which should only happen in one of the above conditions.

-(BKL), which was always helpfully obtained for it by Linux 2.4 VFS

This document attempts to describe the existing locking rules for
JFFS2. It is not expected to remain perfectly up to date, but ought to
be fairly close.

No ordering rules have been made for doing so.
