  To: u-boot

Add spi driver for sun4i, sun5i and sun7i SoCs. The driver is
adapted from mailine kernel.

Signed-off-by: Stefan Mavrodiev <stefan@olimex.com>
---
 Changes for v3:
    - Add required changes in dts and defeconfig file for testing

 Changes for v2:
    - Updated copyright including original owners
    - Remove write/read register function. They are replaced with direct opts
    - Some coding style changes

  To: u-boot

Driver testing is done with A20-OLinuXino-Lime2. Testing
requirements are:
  - Exposing spi0 alternative pins in the dts file
  - Add alias node, enabling driver probing
  - Enable spi flash related options in the defconfig file

The testing log is:

Lime2 doen't have in-built spi-nor is it?

Hi,

I have problem with the driver. I'm not sure where the problem is.
Without calling sspi first, sf probe doesn't work. I guess driver 
doesn't bind.

The output is:

=> sf probe
Invalid chip select 0:0 (err=-19)
Failed to initialize SPI flash at 0:0

Maybe I'm missing something?

Regards,
Stefan Mavrodiev

Haa..observed similar with sun6i_spi [1], what I've seen is controller
writes are not done with direct 'sf probe'

So with sspi are you able to do ops with sf?

Hi,

I've made some fast debugging with/without sspi command.

=> sf probe
spi_find_chip_select() -> device_find_first_child(spi at 01c05000)
device_find_first_child() -> parent: spi at 01c05000
device_find_first_child() -> child_heads is empty!
Invalid chip select 0:0 (err=-19)
Failed to initialize SPI flash at 0:0

=> sspi
spi_find_chip_select() -> device_find_first_child(spi at 01c05000)
device_find_first_child() -> parent: spi at 01c05000
device_find_first_child() -> child_heads is empty!
spi_get_bus_and_cs: Binding new device 'generic_0:0', busnum=0, cs=0, 
driver=spi_generic_drv
device_bind_common() - name: generic_0:0; parent name: spi at 01c05000
spi_get_bus_and_cs: bus=7af3c138, slave=7af4bd7

=> sf probe
spi_find_chip_select() -> device_find_first_child(spi at 01c05000)
device_find_first_child() -> parent: spi at 01c05000
spi_find_chip_select: plat=7af4bd68, cs=0
spi_get_bus_and_cs: bus=7af3c138, slave=7af4bd78
SF: Detected w25q128bv with page size 256 Bytes, erase size 4 KiB, total 
16 MiB

What I can see is that the flash device never get binded with spi 
driver. The sspi command
creates generic spi device, which later is used by sf opts.

I think flash device doesn't get read from the DT when 
CONFIG_DM_SPI_FLASH is enabled.
If legacy controls are enabled maybe there should be way to bind driver 
to device?

Stefan Mavrodiev
