[RFC PATCH 0/2] S3C64XX: Add support of s3c64xx spi-gpio driver

[Matt Hsu]

In order to talk to LCM device on gta03, it's requisite to have something like
s3c64xx_spi_gpio driver. Currently, this driver works perfectly on gta03. 
For the functional perspective, it's fine for me. 

But for the upstream, there are lots of code segments the same among s3c24xx_spi_gpio.c
, s3c64xx_spi_gpio.c and glamo_spi_gpio.c. The vital difference among them is the GPIO control. 
For the long term, we should have a generic-spi-gpio driver to do these bitbang stuff. 

And I found the following,

But it's not in the upstream. Does anyone know any consideration on this?
