spigen problem

[Mori Hiroki]

Hi

I add small spi lcd on RT3050. This lcd controller is S6D0151.

S6D0151 transfer is tree byte command then tree byte data.

I use spigen mruby rapper. This rapper use SPIGENIOC_TRANSFER.

I try to send tree byte command. But spi transfer is six byte.

This is reason.

sys/dev/spibus/spigen.c

        error = copyin(st->st_command.iov_base, transfer.tx_cmd,
           transfer.tx_cmd_sz = transfer.rx_cmd_sz = st->st_command.iov_len);  


This lcd not work six byte transfer.

How do I fix this ?

Regards
