[linux-sunxi] Hardware question, FPC connectors.

I have some 24pin flex cable CIF cameras here. They are labeled with pin 1 and pin 24. But some of them have the metal lands on the top side of the FPC cable and some of them have the metal on the bottom side of the cable. The matching connector on the PCB is also labeled for pin 1 and pin 24.

[linux-sunxi] [PATCH v2 2/5] ARM: dts: sunxi: Add dtsi for AXP22x PMIC

The AXP22x family of PMIC is used with some Allwinner SoCs. This includes the AXP221, AXP221s and AXP223. They differ in the host interface, maximum supply current for DCDC1 regulator, and default voltage and state for various LDO regulators. Also, the AXP221s does not support fine calibration of

[linux-sunxi] [PATCH v2 5/5] ARM: dts: sun6i: Add support for Sinlinx A31s SDK board

The Sinlinx A31s SDK is a A31s based module/baseboard development kit. The core module has the SoC, PMIC, DRAM, eMMC and supporting components. There are also pads for UART0, JTAG and I2S. The baseboard has 100 Mbps Ethernet, 5x USB 2.0 host ports via a USB 2.0 hub chip, MMC, HDMI, SPDIF, CIR,

[linux-sunxi] [PATCH v2 0/5] ARM: sunxi: Sinlinx SinA31s support / AXP22x dtsi conversion

Hi Maxime, This is v2 of the Primo81/SinA31s series. I dropped the Primo81 stuff as it needs more work. Changes since v1: - Requires "ARM: dts: sun6i: hummingbird: Drop AXP221 DC1SW and DC5LDO supplies" - Dropped already merged patches - Dropped Primo81 patch; needs more work to

[linux-sunxi] [PATCH v2 3/5] ARM: dts: sun6i: hummingbird: Use axp22x.dtsi for AXP221 regulators

Now that we have axp22x.dtsi describing common axp22x hardware, use it and reference the nodes instead of declaring the whole tree. Also drop the "always-on" from the vdd-gpu regulator, since we don't support the GPU anyway. And add a regulator reference for cpu0. Signed-off-by: Chen-Yu Tsai

[linux-sunxi] [PATCH] ARM: dts: sun7i: Add regulator configuration for pcDuino v3 Nano

The power configuration on this board is the same as the pcDuino v3. This will enable frequency/voltage scaling over the standard A20 operating points from 144 MHz to 960 MHz. Tested using cpufreq-ljt-stress-test on two pcDuino v3 Nano boards; also tested successfully with voltages reduced by

Hi Maxime, I wanted to discuss this with you at ELCE, but I forgot. I still believe that just setting the regulator to always-on is the best option, see the end of the quoted mail why I think that the other options are not a good idea. I would really like to see this resolved... On 22-09-15

[linux-sunxi] [PATCH v2] ARM: dts: sun7i: Correct USB regulators on pcDuino v3 Nano

The LinkSprite pcDuino v3 Nano's two USB host ports are powered by a single RT9701GB regulator, which has its enable input tied to the A20's PD2 pin, pulled up to 3v3 via a 10k resistor. However, the script.bin that shipped with the device listed PH11 and PH3 as Vbus control pins for the two USB
