Compared to i.MX6 Quad/Dual the CCM_CCGR1 register in the i.MX6 Solo/DualLite
replaces the ecspi5 clock with the i2c4 clock.
Handle this difference using cpu_is_imx6dl().

This patch allows for easy integration of a custom Linux boot logo to
replace the Tux' being shown by default.
Use gimp or the like to create a raw PPM in your desired resolution.
Reduce the number of colours in the image to 224:
user@host:~$ ppmquant 224 Toradex-640x480.ppm > \
Toradex-640x480-224.ppm
ppmquant: making histogram...
ppmquant: 370 colors found
ppmquant: choosing 224 colors...
ppmquant: mapping image to new colors...
Convert it from raw PPM to ASCII format:
user@host:~$ pnmnoraw Toradex-640x480-224.ppm > \
Toradex-640x480-ascii-224.ppm
Copy it into the Linux sources:
cp Toradex-640x480-ascii-224.ppm linux-toradex/drivers/video/logo/\
logo_custom_clut224.ppm
Activate exclusively custom Linux logo in the kernel configuration:
Device Drivers -> Graphics support -> Bootup logo ->
Custom 224-color Linux logo
And re-compile the kernel.

The camera driver knows if it uses mipi or parallel, and in case a camera
can do both it makes sense that this is in the device tree node for the
camera and not the generic mxc_v4l2_capture.

If the I2C is disturbed by other signals sometimes the i2c-imx bus gets stuck
with SDA being low.
This adds a recovery function to the bus driver.
When e.g. a device driver detects a stuck bus
int i2c_recover_bus(struct i2c_adapter *adap)
can be called to try to recover the bus.

The capacitive touch 10" display does react badly react badly to the

E.g. only the upper half of the display was somewhat readable with the

Backport of commit dd4d2d6 from main-line.
The VAG_POWER must be enabled after all other bits in CHIP_ANA_POWER
and disabled before any other bit in CHIP_ANA_POWER. See the SGTL5000
datasheet (Table 31, BIT 7, page 42-43). Failing to follow this order
will result in ugly loud "POP" noise at the end of playback.
To achieve such order, use the _PRE and _POST DAPM widgets to trigger
the power_vag_event, where the event type check has to be fixed
accordingly as well.

After a 'reboot' command in Linux or after pressing the system's reset button
the sgtl5000 driver fails to probe:
sgtl5000 0-000a: Device with ID register ffff is not a sgtl5000
sgtl5000 0-000a: ASoC: failed to probe CODEC -19
imx-sgtl5000 sound.12: ASoC: failed to instantiate card -19
imx-sgtl5000 sound.12: snd_soc_register_card failed (-19)
sgtl5000 codec does not have a reset line, nor a reset command in software, so
after a system reset the codec does not contain the default register values
from sgtl5000_reg_defaults[] anymore, as these are only valid after a
power-on-reset cycle.
Fix this issue by explicitly reading all the reset register values from
sgtl5000_reg_defaults[] and writing them back into sgtl5000 to ensure a sane
state.

On a mx28evk with a sgtl5000 codec we notice a loud 'click' sound to happen
5 seconds after the end of a playback.
The SMALL_POP bit should fix this, but its definition is incorrect:
according to the sgtl5000 manual it is bit 0 of CHIP_REF_CTRL register, not
bit 1.
Fix the definition accordingly and enable the bit as intended per the code
comment.
After applying this change, no loud 'click' sound is heard after playback

If the reset gpio for a PCIe switch is invalid, but a gpio for
reseting downstream EP devices is valid no reset pulse for the EP devices is
generated.
(i.e. in the device tree reset-gpio is not defined but reset-ep-gpio is defined)
The patch fixes this.

rework the device-tree include structure to faciliate several device-tree's
depending on HW version.

The key used for wakeup from suspend was named 'Power' and configured to
send the KEY_POWER code. Currently this is misleading, would one add
functionality to the kernel to actually turn off the system when KEY_POWER
is received then this would lead to the wakeup event also generating a
power down event later.
Rename the key to 'Wakeup' and send the KEY_WAKEUP code to the input
subsystem.
If one really would use the key

As stated by the eMMC 5.0 specification, a chip should not be rejected
only because of the revision stated in the EXT_CSD_REV field of the
EXT_CSD register.
Remove the control on this value, the control of the CSD_STRUCTURE field
should be sufficient to reject future incompatible changes.

The Apalis iMX6 V1.1 HW allows the control of RESET_MOCI.
This is now used to reset PCIe endpoint devices until after the PCIe switch
has come out of reset.
|
|
With the following dtb node one can define a gpio to reset
downstream endpoints.
reset-ep-gpio = <...>;
Currently the logic is 1 for reset asserted
and 0 for reset deasserted.
Some pcie switches require their downstream endpoints to be kept in reset
for an additonal millisecond after their reset has been deasserted.

The Freescale provided files imx6qdl.dtsi, imx6q.dtsi provide among
other things pinmux definitions.
We added missing definitions to these files, however that could
become a merging nightmare in the future.
Move our additions into apalis/colibri files and use names which
likely do not collide with future upstream additions.

Use the RTS(CTS) output to control a RS485 transmitter.
The UART obviously needs RTS/CTS enabled for this to work, e.g.
fsl,uart-has-rtscts must be present in the device tree.
Enable RS485 by either using ioctrl TIOCSRS485 or enable it in
the device tree by setting linux,rs485-enabled-at-boot-time.
e.g.
&uart2 {
status = "okay";
linux,rs485-enabled-at-boot-time;
};
