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;
};

This enables the buffers which bring the WE# signal to SODIMM-93/99
and tri-states the CPU pins directly connected to SODIMM-93/99.
|
|
All pins not assigned to other functionality are muxed to be
gpio. This allows for later sysfs access to these pins.
Some USB OTG control signals are among the list as the driver for
these is not yet ready.

UART A was lacking DCD/DSR/DTR muxing,
UART C pinmuxing was set for DCE.

MIC_GND is controlled with a FET. With a pullup set in the dtb MIC_GND
is active by default.
|
|
On the evaluation board is a pull down on this line, thus
low active makes more sense.

Enable the external memory bus, aka weim.
Define a sram at CS0 and one at CS1, each in non multiplexed mode.
|
|
Evaluate the ranges property of the weim node to setup the chip select
memory map in IOMUXC_GPR1.
Note that the implementation assumes the ranges property to be sorted from CS0
to the last CS used.
e.g. for CS0, CS1, CS2 used, each having a range of 32MB:
ranges = <0 0 0x08000000 0x02000000
1 0 0x0a000000 0x02000000
2 0 0x0c000000 0x02000000>;

Make the CMA size half the RAM size or 256MB whatever is less.
Thus on a Colibri iMX6S (with 256MB RAM) CMA will be 128MB,
on a Colibri iMX6DL (with 512MB RAM) CMA will be 256MB.

Vivante patch name:
fix_fsl_2d_base_on_p13.v2.rls.diff
-Updated the outstanding request limit to 12.
-Refined the 2D chip feature check.
-Refine the 2D cache flush operation
(avoid FE and PE access memory through the same port).
-Enable cache flush for filterblt.
-Dynamic enabling SPLIT_RECT by checking chip feature(disable for us)
-Use brush stretch blt for clear operation.
-Enable SplitFilterBlit to workaround the 2d hang issue in filterblit case.
-Refine 2d line operation.

Fix PCIe operation by disabling RC/EP test mode which according to the
following community forum post is only used on the PCIe EP/RC
validation system and otherwise prevent PCIe from working properly:

imx6qdl-apalis.dtsi: enable stmpe-adc in device tree
defconfig: add stmpe-adc to minimal defconfig
|
|
|
|
This adds an ADC driver for the STMPE device using the industrial
input/output interface. The driver supports raw reading of values.
The driver depends on the MFD stmpe driver. If the touchscreen
block is enabled too, only for of the 8 ADC channels are available.
Conflicts:

drivers/staging/iio/adc/Kconfig
drivers/staging/iio/adc/Makefile
Adaptions due to staging iio subsystem changes:
drivers/staging/iio/adc/stmpe-adc.c
|
|
In order to use the auxiliar ADC inputs of STMPE811 devices we need
to add resources for the ADC block. Also move the ADC macros from
the touchscreen driver to the general header file. We will need them
for the ADC driver in future.

suspend/resume
This patch ensures that the SCU and certain A9 CP15 registers state are maintained across
a suspend/resume cycle:
1. Need to ensure that SCU standby bit is set again after suspend/resume cycle, else
the system will never WAIT mode after a suspend/resume cycle. This bit should be enabled
on all SMP systems immaterial of whether CPUIDLE is enabled or not.
2. Several A9 errata workarounds involve setting bits in the ARM diagnostic register.
Save/restore this register across a suspend/resume cycle.
3. Save and restore the A9 power control register also.
