4f1cfdc250 ARM: dts: armadillo800eva: Convert to named i2c-gpio bindings
Commits 7d29f509d2 ("dt-bindings: i2c: i2c-gpio: Add support for
named gpios") and 05c7477885 ("i2c: gpio: Add support for named
gpios in DT") introduced named i2c-gpio DT bindings, and deprecated the
more error-prone unnamed variant.

Switch to the new bindings, and add the missing GPIO_OPEN_DRAIN I/O
flags, which were implicitly assumed before.

The latter gets rid of the message:

    gpio-208 (?): enforced open drain please flag it properly in DT/ACPI DSDT/board file
    gpio-91 (?): enforced open drain please flag it properly in DT/ACPI DSDT/board file

13132b3f44 ARM: dts: armadillo800eva: Split LCD mux and gpio
Configuration of the lcd0 pinmux group and GPIO hog for the external
GPIO mux are done using a single device node, causing the "output-high"
property to be applied to both.  This will fail for the pinmux group,
but doesn't cause any harm, as the failure is ignored silently.

However, after "pinctrl: sh-pfc: propagate errors on group config", the
failure will become fatal, leading to a broken display:

    sh-pfc e6050000.pin-controller: pin_config_group_set op failed for group 102
    sh-pfc e6050000.pin-controller: Error applying setting, reverse things back
    sh-pfc e6050000.pin-controller: failed to select default state

Move the GPIO hog to its own node to fix this.

1403e38b82 ARM: dts: armadillo800eva: Update console parameters
Change the console alias to "serial0", for consistency with other
boards (the first unlabeled serial port is always called "serial0").
This does change the serial console from /dev/ttySC1 to /dev/ttySC0.
Add the serial port config to "chosen/stdout-path", which requires
referring to the port by alias.
Drop the "console=" parameters from the kernel command line, as they're
no longer needed for DT-based platforms.

1ba1e26ede ARM: dts: armadillo800eva: use generic pinctrl properties
Since 16ccaf5bb5 ("pinctrl: sh-pfc: Accept standard function, pins and

and "groups" properties.

This patch updates the armadillo800eva device tree to use the generic
properties.

c61f30a255 ARM: dts: armadillo800eva Correct extal1 frequency to 24 MHz
On r8a7740/armadillo, actual clock rates are ca. 4% lower than reported
by /sys/kernel/debug/clk/clk_summary. Correct the extal1 frequency from
25 MHz to 24 MHz to fix this.

This matches the Armadillo-800 EVA Product Manual, which claims the main
crystal runs at 24 MHz, and the old legacy/reference board code.

0cc16889e7 ARM: dts: shmobile/r8a7xxx: replace gpio-key, wakeup with wakeup-source property
Though the keyboard driver for GPIO buttons(gpio-keys) will continue to
check for/support the legacy "gpio-key,wakeup" boolean property to
enable gpio buttons as wakeup source, "wakeup-source" is the new
standard binding.

This patch replaces the legacy "gpio-key,wakeup" with the unified
"wakeup-source" property in order to avoid any futher copy-paste
duplication.

In addition, this will allow the PM domain code to find the PM domain

chosen/bootargs, else we only get console messages on tty0, and because
this DTS is shared between legacy and multi-platform.

Take the contents from the Armadillo800EVA DT reference DTS
and add them to the "regular" Armadillo800EVA DTS. This is
preparation for removal of the DT reference DTS. So the goal
is to have a single DTS for this Armadillo board.

The SoC "r8a7740" is added to compatible string but the board
is left as-is (excluding the reference suffix).

The kernel command line is left as-is, earlyprintk is used in
case of legacy and for multiplatform we can simply ignore it
for now.
