We no longer have a provision for proc entries in the latest GPIO driver. That is the reason you do not see /proc/gio. In arch/arm/mach-davinci/board-dm355-evm.c, have a look at the setup_ethernet() function. That will give an example as to how you can use the gpio driver.
Thanks, Sandeep -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Andrea Gasparini Sent: Monday, July 28, 2008 10:45 AM To: [email protected] Subject: Gio Interface on DM355 Hi, i'm attempting to create a Gio driver for our purpose, with DM355 and dvsdk_1_30_00_40. While with the oldest kernel i was able to create a working one, now i'm not stil able, because of changes in the kernel interface. in particular: - i don't see /proc/gio/ directory. - i can't use gpio_interrupt_disable and gpio_interrupt_enable, and using only the base function "request_irq" doesn't work. I see that's now exists gpio_irq_handler() and davinci_gpio_irq_setup() in arch/arm/mach-davinci/gpio.c, but they're declared as static, and so i thought there must be an interface that i'm still missing. Could you please point me to a document or a fragment of code that could works with this new SDK? my kernel version is this: # uname -a Linux 192.168.1.71 2.6.10_mvl401 #1 Fri Jul 11 15:52:11 CEST 2008 armv5tejl GNU/Linux Thanks, best regards! -- Andrea Gasparini ---- ImaVis S.r.l. ---- web: www.imavis.com _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
