Hi Chris, I am deeply sorry for our firewall still stops me to send email by git. I post it in web and this patch should be not able to be applied. Then i attatched the origianl patch as an attachment. Our IT will open related ports. Then we can send formated patches later. > > * Where is the patch that implements the get_shared_pins() hook in > your driver? We send the common level patch ahead to get the upstream agreement so that we can maintain our bottom level sdhci codes better. We will send the special driver patch after some time. Basically, the driver get a mutex and set hardware registers to make the related pin switch roles. > > Thanks, > > - Chris. > -- > Chris Ball <c...@laptop.org> <http://printf.net/> > One Laptop Per Child > -- > To unsubscribe from this list: send the line "unsubscribe linux-mmc" in > the body of a message to majord...@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html >
