2017-06-08ARM: dts: armadillo800eva: Split LCD mux and gpioGeert Uytterhoeven1-0/+2
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.

2016-06-29ARM: dts: armadillo800eva: Update console parametersGeert Uytterhoeven1-3/+3
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.

2016-06-14ARM: dts: armadillo800eva: Name serial port pfc subnode after device nameGeert Uytterhoeven1-1/+1
Name the Pin Function Controller subnode for SCIFA1 after its device name, instead of after the serial port alias. This avoids conflicts when enabling support for more serial ports later, either here or in a DT overlay.

2016-03-28ARM: dts: armadillo800eva: use generic pinctrl propertiesSimon Horman1-17/+17
Since 16ccaf5bb5a5 ("pinctrl: sh-pfc: Accept standard function, pins and groups properties") renesas pfc drivers accept generic "function", "pins" and "groups" properties. This patch updates the armadillo800eva device tree to use the generic properties. Signed-off-by: Simon Horman <horms+renesas@verge.net.au> Acked-by: Geert Uytterhoeven <geert+renesas@glider.be>

2016-01-18ARM: dts: armadillo800eva Correct extal1 frequency to 24 MHzGeert Uytterhoeven1-1/+1
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.

2015-10-23ARM: dts: shmobile/r8a7xxx: replace gpio-key, wakeup with wakeup-source propertySudeep Holla1-1/+1
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.

2014-10-24ARM: shmobile: armadillo800eva dts: Add chosen/stdout-pathGeert Uytterhoeven1-0/+1
Add a stdout-path property so that automatic console selection works in the absence of a "console=" parameter on the kernel command line. In addition, this will allow the PM domain code to find the PM domain for the console device. Note that we have to keep the "console=ttySC1" parameter in chosen/bootargs, else we only get console messages on tty0, and because this DTS is shared between legacy and multi-platform.

2014-09-02ARM: shmobile: armadillo800eva: Sync DTSMagnus Damm1-1/+275
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.
