Allwinner A100 Initial support

This patch set adds initial support for allwinner a100 soc, which is a 64-bit tablet chip.

v3:
-Add pmu and nmi support
-Add read data mask for calibration
-Code style
-Some trivial things in yaml files

v2:
-Some naming consistency
-Repair email address
-Fix mmc clock
-Don't export system clock
-Fix checkpatch warning
-Drop unneeded pin function, convert to jtag_gpu and i2s_x

Hello,

What if the borad doesn't use one of the banks? How would I describe such a board if defining supplies for all banks is required?

regards,

	o.

Hi,

If that case ever comes up, we can always drop the requirement, it's going to be backward compatible.

Maxime

Maybe we put this work backwards and let a100 join the mainline as soon as possible.

This commit introduces support for the pin controller on A100.

1.9.1

For sun50i_h6_ths_calibrate(), the data read from nvmem needs a round of calculation. On the other hand, the newer SOC may store other data in the space other than 12bit sensor data. Add mask operation to read data to avoid conversion error.

The AXP803 can be used both using the RSB proprietary bus, or a more traditional I2C bus.

Let's add that possibility.

Hello

Does a product already exists with it ? I couldnt found any. Does a datasheet is availlable ?

Regards

The product is still in development, A133 is actually a high performance version of A100.

Yangtao

Hi,

it doesn't look like those patches went through?

On a more general topic, which bootloader have you used to test this? The one from Allwinner's BSP I assume?

Maxime

HI,

Due to sending too many emails at once, it seems that some emails have been filtered by the mailbox, and I just reissued them.

Yeah, there is no bringup on the mainline BootLoader yet.

If nothing happens, the next edition will be released today. We hope that A100 will be integrated as soon as possible.

MBR,
Yangtao
