Thanks for testing, review and feedback. I have resent a complete v3 of this series taking into account your comments there. > However the gpio are numbers > 480-511 > 448-479 > 416-447 > > instead of > 0-31 > 32-63 > 64-95 > > which would be more normal. > Maybe when you resubmit I'll raid it with Linus Walleij and see if he > can explain why I can't have 0-95. This change is because the chip.base property changed to be -1 for dynamic enumeration of the gpio's. In this mail there is some explanation about it: http://lists.infradead.org/pipermail/linux-rpi-kernel/2014-October/001045.html Best regards, Sergio Paracuellos > > Thanks, > NeilBrown > > > > > > Best regards, > > Sergio Paracuellos > > > > Sergio Paracuellos (7): > > staging: mt7621-gpio: make use 'bgpio_init' from GPIO_GENERIC > > staging: mt7621-gpio: avoid including 'gpio.h' > > staging: mt7621-gpio: make use of 'builtin_platform_driver' > > staging: mt7621-gpio: implement '.irq_[request|release]_resources' > > functions > > staging: mt7621-gpio: add COMPILE_TEST > > staging: mt7621-gpio: add kerneldoc for state data containers > > staging: mt7621-gpio: implement high level and low level irqs > > > > drivers/staging/mt7621-gpio/Kconfig | 3 +- > > drivers/staging/mt7621-gpio/gpio-mt7621.c | 251 > > ++++++++++++++++-------------- > > 2 files changed, 138 insertions(+), 116 deletions(-) > > > > -- > > 2.7.4 _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
