The Pistachio target is a MIPS interaptiv based SoC developed by
Imagination Technologies. It includes blocks for i2c, spi, audio,
usb and WiFi.
This also adds the base support for the 'Creator Ci40 (marduk)'
device which uses the Pistachio SoC to create an IoT hub by
including Bluetooth, WiFi and 6lowpan on one board. Additionally 2x
Mikrobus ports are available to expand with further RF technologies
or add sensors. You can find out more here http://creatordev.io.
Note, this commit is just the initial board support hence the
following are not expected to work yet:
* WiFi
* Bluetooth
* 6lowpan
* Audio
* Mikrobus uarts, user leds (clock dependency of 6lowpan chip)
The aim of this commit is to essentially have the same level of
support that currently exists in the mainline kernel.

This adds kernel support for the Pistachio SoC and the Marduk (Ci40)
board which uses it.
Much of the code for Pistachio has been upstreamed however some
patches are still required to boot from the Marduk board:
* spi bug fixes
* dma bug fixes
* pistachio internal clock tree bug fixes
* spi-nand implementation
* dts based mtd device naming scheme
* dts backports and bug fixes

This patch adds support for AVM FRITZ!Box 4040.
hardware highlights:
SOC: IPQ4018 / QCA Dakota
CPU: Quad-Core ARMv7 Processor rev 5 (v7l) Cortex-A7
DRAM: 256 MiB Nanya NT5CC128M16IP
FLASH: 32 MiB MXIC MX25L25635FMI
ETH: Qualcomm Atheros QCA8075 Gigabit Switch (4 x LAN, 1 x WAN)
USB: 1 x 3.0 (via Synopsys DesignWare DWC3 controller in the SoC)
1 x 2.0 (via Synopsys DesignWare DWC3 controller in the SoC)
WLAN1: Qualcomm Atheros QCA4018 2.4GHz 802.11bgn 2:2x2
WLAN2: Qualcomm Atheros QCA4018 5GHz 802.11a/n/ac 2:2x2
INPUT: one WLAN and one WPS button
LEDS: Power, WAN/Internet, WIFI, INFO (red and amber) and LAN.
Serial:
WARNING: The serial port needs a TTL/RS-232 v3.3 level converter!
The Serial setting is 115200-8-N-1. The SoC's serial port is right
next to the MXIC FLASH chip. The board has a unpopulated 1x4 0.1"
header for it. Use a multimeter to figure out the pinout!
This board currently needs an additional u-boot image in order to boot
properly. Booting with EVA isn't possible ATM.
Install Procedure:
0. It's highly recommended to connect to the serial port.
The serial settings are listed above.
1. install a u-boot image for AVM Fritz!Box 4040
(see <https://github.com/chunkeey/FritzBox-4040-UBOOT/releases> and
<https://github.com/chunkeey/FritzBox-4040-UBOOT/blob/master/upload-to-f4040.sh>)
2. upload the initramfs.itb image via tftp (u-boot listens to
192.168.1.1 - use binary transfer mode!)
3. connect to the FB4040 and use sysupgrade sysupgrade.bin
to install the image.
Works:
- Switch and Ethernet (99%)
- Buttons (WLAN, WPS)
- FLASH (1 x 32MiB NOR Chip)
- WLAN2G and WLAN5G
- CPUFREQ scaling
- PRNG
- serial
- Crypto Accelerator
- sysupgrade (Read the flash instructions to avoid bricking)
- full LEDE Install (Read the flash instructions to avoid bricking)
- LEDs (Power, WAN, Info (red and amber), LAN)
The LEDs are connected to the QCA8075 LED ports.
The AR40xx driver contains a gpio-controller to
handle these special "GPIOs".
- USB Both 3.0 and 2.0 ports
- many packages from other ARMv7 boards
(This does include the RaspberryPi Model 2!)
- ...
Not planned:
- WAN<->LAN short-cut
- Qualcomm Secure Execution Environment
- ...

For IPQ806x targets, TZ protects the registers that are used to
configure the routing of interrupts to a target processor.
To resolve this, this patch uses scm call to route GPIO interrupts
to application processor. Also the scm call interface is changed.

At the moment as a workaround definition for scm firmware in DT is used as if it is
apq8064 board. This leads to incomplete scm firmware initialization and as a result
cpuidle driver fails to configure.
By design unlike other qcom boards ipq do not use clocks to connect to scm.
Considering this we're removing from DT and scm driver clocks for ipq boards.
As a result cpuidle does not produce errors about failed configuration anymore.

SMP state is generally affected by
- CONFIG_SMP build-time kernel configuration option and
- 'nosmp' runtime kernel commandline option
The SMP state within vpe-mt.c is determined by CONFIG_SMP option.
A runtime check is needed if VPE functionality
should be used with a kernel image that supports SMP.
This fix introduces a check for 'nosmp' command line option
if CONFIG_SMP kernel configuration option is enabled.
Note: This patch is needed to use lantiq FXS if CONFIG_MIPS_MT_SMP
(that activates CONFIG_SMP) is enabled within kernel configuration
and the 'nosmp' command line argument is given to disable SMP at runtime.
Without this patch CONFIG_MIPS_MT_SMP must be disabled before using FXS.
With this patch setting the 'nosmp' parameter is enough.
In general, concurrent usage of FXS and SMP
is incompatible and will cause kernel panics.

The problem is caused by the incorrect handling of the parent inode's
i_nlink count for the dentry to be RENAME_EXCHANGED. There are 3 cases
to consider. Assume we want to RENAME_EXCHANGE struct dentry *a and
struct dentry *b, and inode_a is pointed to by dentry_a, inode_b is
pointed to by dentry_b:
1. If inode_a is a directory, but inode_b isn't, then we must decrease
the i_nlink count of old_dir_i, and increase the i_nlink of new_dir_i.
2. If inode_a isn't a directory, but inode_b is a directory, then we
must increase the i_nlink of old_dir_i, and decrease the i_nlink count
of new_dir_i.
3. If the types of inode_a and inode_b are the same, we don't change the
i_nlink for either old_dir_i or new_dir_i.

Switch to the common LED related status_led_blink_* functions in
set_state() as it's done in most of other targets.
Also, use "status_led_on" instead of "status_led_set_heartbeat"
and incorrect "status_led_set_on" in the "done" state.
Moreover, remove outdated comment from the script.

but not all of them.

The available amount of coherent DMA memory is very limited. On Linux
4.4 this issue was worked around by increasing the pool size.
It turns out that using coherent memory here is completely unnecessary.
This change reworks the driver code to use kzalloc+dma_map_single
instead.
