Chips&Media Coda multi-standard codec IP
========================================
Coda codec IPs are present in i.MX SoCs in various versions,
called VPU (Video Processing Unit).
Required properties:
- compatible : should be "fsl,<chip>-src" for i.MX SoCs:
(a) "fsl,imx27-vpu" for CodaDx6 present in i.MX27
(b) "fsl,imx53-vpu" for CODA7541 present in i.MX53
(c) "fsl,imx6q-vpu" for CODA960 present in i.MX6q
- reg: should be register base and length as documented in the
SoC reference manual
- interrupts : Should contain the VPU interrupt. For CODA960,
a second interrupt is needed for the MJPEG unit.
- clocks : Should contain the ahb and per clocks, in the order
determined by the clock-names property.
- clock-names : Should be "ahb", "per"
- iram : phandle pointing to the SRAM device node
Example:
vpu: vpu@63ff4000 {
compatible = "fsl,imx53-vpu";
reg = <0x63ff4000 0x1000>;
interrupts = <9>;
clocks = <&clks 63>, <&clks 63>;
clock-names = "ahb", "per";
iram = <&ocram>;

TPS65217 family of regulators
The TPS65217 chip contains a boost converter and current sinks which can be
used to drive LEDs for use as backlights.
Required properties:
- compatible: "ti,tps65217"
- reg: I2C slave address
- backlight: node for specifying WLED1 and WLED2 lines in TPS65217
- isel: selection bit, valid values: 1 for ISEL1 (low-level) and 2 for ISEL2 (high-level)
- fdim: PWM dimming frequency, valid values: 100, 200, 500, 1000
- default-brightness: valid values: 0-100
Each regulator is defined using the standard binding for regulators.
Example:
tps: tps@24 {
reg = <0x24>;
compatible = "ti,tps65217";
backlight {
isel = <1>; /* 1 - ISET1, 2 ISET2 */

Enable this only if you want to export the FAT filesystem
over NFS.
stale_rw: This option maintains an index (cache) of directory
inodes by i_logstart which is used by the nfs-related code to
improve look-ups. Full file operations (read/write) over NFS is
supported but with cache eviction at NFS server, this could
result in ESTALE issues.
nostale_ro: This option bases the inode number and filehandle
on the on-disk location of a file in the MS-DOS directory entry.
This ensures that ESTALE will not be returned after a file is
evicted from the inode cache. However, it means that operations
such as rename, create and unlink could cause filehandles that
previously pointed at one file to point at a different file,
potentially causing data corruption. For this reason, this
option also mounts the filesystem readonly.
To maintain backward compatibility, '-o nfs' is also accepted,
defaulting to stale_rw
Enable this only if you want to export the FAT filesystem
over NFS
