The imx8mm-venice-gw73xx-0x som+baseboard combination has a multi-protocol
RS-232/RS-485/RS-422 transceiver to an off-board connector which
can be configured in a number of ways via UART and GPIO configuration.
The default configuration per the imx8mm-venice-gw73xx-0x dts is for
UART2 TX/RX and UART4 TX/RX to be available as RS-232:
J15.1 UART2 TX out
J15.2 UART2 RX in
J15.3 UART4 TX out
J15.4 UART4 RX in
J15.5 GND
Add dt overlays to allow additional the modes of operation:
rs232-rts (UART2 RS-232 with RTS/CTS hardware flow control)
J15.1 TX out
J15.2 RX in
J15.3 RTS out
J15.4 CTS in
J15.5 GND
rs485 (UART2 RS-485 half duplex)
J15.1 TXRX-
J15.2 N/C
J15.3 TXRX+

Add support for i2c5, which is used to access the
external I2C bus on connector J22 of the imx8mp-evk.
Limit the speed to 100kHz since this is an external I2C bus.
Disabled by default, since it is shared with the CAN1 bus.
To enable i2c5, you need to disable the CAN1 function, enable the i2c5
function and also configure the CAN1/I2C5_SEL GPIO to HIGH to
select i2c5 instead of CAN1. This can be done by defining a gpio-hog
inside the pca6416 node, in your board device tree, like in this example:
&flexcan1 {
status = "disabled";
};
&i2c5 {
status = "okay";
};
&pca6416 {
can1-i2c5-sel-hog {
gpio-hog;
gpios = <2 GPIO_ACTIVE_HIGH>;
output-high;
line-name = "can1-i2c5-sel";
};
};

This patch adds the device tree to support Toradex Verdin iMX8M Mini a
computer on module which can be used on different carrier boards.
The module consists of an NXP i.MX 8M Mini family SoC (either i.MX 8M
Mini Quad or 8M Mini DualLite), a PCA9450A PMIC, a Gigabit Ethernet PHY,
1 or 2 GB of LPDDR4 RAM, an eMMC, a TLA2024 ADC, an I2C EEPROM, an
RX8130 RTC, an optional SPI CAN controller plus an optional Bluetooth/
Wi-Fi module.
Anything that is not self-contained on the module is disabled by
default.
The device tree for the Dahlia includes the module's device tree and
enables the supported peripherals of the carrier board.
The device tree for the Verdin Development Board includes the module's
device tree as well as the Dahlia one as it is a superset and supports
almost all peripherals available.
So far there is no display functionality supported at all but basic
console UART, PCIe, USB host, eMMC and Ethernet and PCIe functionality
work fine.

Since commit 9a0f3b157e22 ("arm64: dts: imx8mn: Enable GPU")
imx8mn-venice-gw7902 will hang during kernel init because it uses
a MIMX8MN5CVTI which does not have a GPU.
Disable pgc_gpumix to work around this. We also disable the GPU devices
that depend on the gpumix power domain and pgc_gpu to avoid them staying
in a probe deferred state forever.

Without a OPP table or a downstream TF-A running on the system the DDRC will
fail to probe, as it has no means to scale the DRAM frequency in that case.
This however will block the bus scaling driver to come up and this in turn
prevents other devices that hook into the interconnect from probing.
If the DDRC is disabled, the interconnect driver will simply ignore it. As
most systems don't want to scale the DRAM frequency, disable the node by
default and only enable it on the systems that actually uses this
capability and provides a valid OPP table in the DT.

Pull ftrace fix from Steven Rostedt:
"Fix s390 breakage from sorting mcount tables.
The latest merge of the tracing tree sorts the mcount table at build
time. But s390 appears to do things differently (like always) and
replaces the sorted table back to the original unsorted one. As the
ftrace algorithm depends on it being sorted, bad things happen when it
is not, and s390 experienced those bad things.
Add a new config to tell the boot if the mcount table is sorted or
not, and allow s390 to opt out of it"
* tag 'trace-v5.17-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
ftrace: Fix assuming build time sort works for s390
|
|
To speed up the boot process, as mcount_loc needs to be sorted for ftrace
to work properly, sorting it at build time is more efficient than boot up
and can save milliseconds of time. Unfortunately, this change broke s390
as it will modify the mcount_loc location after the sorting takes place
and will put back the unsorted locations. Since the sorting is skipped at
boot up if it is believed that it was sorted at run time, ftrace can crash
as its algorithms are dependent on the list being sorted.
Add a new config BUILDTIME_MCOUNT_SORT that is set when
BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
if sorting should take place at boot up.
