I think I'll remove it instead. The device ships with a U-Boot and Android installation where blue means "on" and red means "stand-by" (which is simply implemented by blanking the screen, it seems), but I doubt many people want to run the rather old Android version available for this device. Instead, I was going to point to the quick setup guide, but it has no mention of the LEDs at all, so I guess the user won't expect the blue LED to turn on. > > + /* USB 3.0 OTG connector.

The MMC core, without broken-cd, requests the GPIO driver to enable interrupt delivery on the pin and will fall back to polling the GPIO pin if the GPIO driver refuses to enable interrupt delivery. What I see is that the GPIO driver accepts to deliver interrupts, but only the first interrupt is triggered (as evident from /proc/interrupts showing only 1). The vendor sys_config.fex also sets the GPIO pin to polled operation, so maybe there is a hardware bug. The sunxi-mmc driver doesn't really support operation with broken-cd only because it spams the console and dmesg with useless error messages, see https://www.mail-archive.com/linux-sunxi@googlegroups.com/msg19963.html for an example. The comment should probably read something like "GPIO pin delivers no interrupts, poll it". > > + /* 1.8 V (enabled). */ > > + reg_bldo1: bldo1 { > > + regulator-boot-on; > > + regulator-always-on; /* Hang if disabled */ > > If you specify always-on, you don't need to add boot-on.

I'm verbose with the names of the regulators for documentation purposes because unlike some of the boards aimed at developers, documentation is on this device is scarse. I see that with -mmc now added after my latest round of probing with a multimeter, the line went above 80 characters. Will it be OK with vcc-pb,c,d,e,f,h-mmc-spdif?

The Suncip CX-A99 board is found in at least four brands of media players. It features an Allwinner A80 ARM SoC and is found in two models: 1) 2 GiB DDR3 DRAM and 16 GB eMMC 2) 4 GiB DDR3 DRAM and 32 GB eMMC For details of the board, see the linux-sunxi page <URL:https://linux-sunxi.org/Sunchip_CX-A99>. Supported features (+ means tested): + One Cortex-A7 CPU core + AXP808 power management chip + OZ80120 voltage regulator + Serial console port (internal) + eMMC and SD card slot + USB 2.0 host ports on on-board USB hub + SATA port on on-board SATA-to-USB bridge * + IEEE 802.11 a/b/g/n/ac SDIO Wifi + Real-time clock + LEDs - IR receiver for remote control * In addition to connecting a SATA device, some unknown magic is necessary after power-up to get the SATA-to-USB bridge to show up on the USB bus. As a workaround, run the vendor U-Boot once after power-up. So far unsupported features: - Using more than one CPU core or any of the Cortex-A15 CPU cores - USB 3.0 OTG port (except for supplying 5V power) - IEEE 802.3 10/100/1000 megabit Ethernet - HDMI connector - SPDIF audio output - Jack socket with composite video and analog stereo audio - Bluetooth - FM radio receiver (assuming it is even wired on the board) Signed-off-by: Rask Ingemann Lambertsen <rask@formelder.dk> --- Changes in v5: - Switched pinmux modes to generic properties and dropped #include <dt-bindings/pinctrl/sun4i-a10.h> as a consequence. - Dropped pinctrl properties from GPIO nodes and dropped the pinmux nodes for them. - AXP808 regulators added. - Dropped the now unused #include <sunxi-common-regulators.dtsi>. - Ampak AP6335 SDIO-Wifi added. - USB Vbus changes as per v4 comments. - Added "broken-cd" to mmc0 because GPIO interrupts don't work. Changes in v4: - Node names had underscores changed to hyphens. - Changed formatting of the ac100/rtc node's clock output name list to match that of the same node in the cubieboard4 and a80-optimus device trees. Changes in v3: None. Changes in v2: - Fixed formatting and style issues found by scripts/checkpatch.pl. arch/arm/boot/dts/Makefile | 3 +- arch/arm/boot/dts/sun9i-a80-cx-a99.dts | 413 +++++++++++++++++++++++++++++++++ 2 files changed, 415 insertions(+), 1 deletion(-) create mode 100644 arch/arm/boot/dts/sun9i-a80-cx-a99.dts
