No, not true.
Both Topcliff(Intel EG20 PCH) and OKISEMI ML7213 IOH SPI devices
can't use multi-ChipSelect but 1 ChipSelect only.
I show the my modified diagram below.
- Currently upstreamed version,
/sys/devices/.../0000:00:1a.0 (pci_dev bound to driver 'pch_spi_pcidev')
|
\--spi0.0 (spi_device 0 on spi_master 0)
- I posted before version.
/sys/devices/.../0000:00:1a.0 (pci_dev bound to driver 'pch_spi_pcidev')
|
+--spi0.0 (spi_device 0 on spi_master 0)
|
\--spi1.0 (spi_device 0 on spi_master 1)
- Your anticipated becomes like below
/sys/devices/.../0000:00:1a.0 (pci_dev bound to driver 'pch_spi_pcidev')
|
+--pch_spi.0
| |
| +--spi0.0 (spi_device 0 on spi_master 0)
|
\--pch_spi.1
|
\--spi1.0 (spi_device 0 on spi_master 1)
Still above, don't you change your opinion?

I probably understand your saying.
You mean insert platform_device as wrapper between pci_driver and
spi_topcliff_pch.
Thanks,
