Vikram, it seems to me you sent the already NAKed patch to me https://github.com/dirkbehme/u-boot-imx6/pull/2 again? Please send U-Boot patches only to this U-Boot mailing list. Dirk

We have already (and probably too many) GPIO_TO_PORT: Yes. You are right. So, instead of defining all the headers this way, #if defined(CONFIG_MX53) || defined(CONFIG_MX51) #include <asm/arch/mx5x_pins.h> #elif defined(CONFIG_MX6) #include <asm/arch/imx-regs.h> #endif ..... etc Why not define the GPIO_TO_PORT macro in the driver? Anyways for all its the same 32 pins. Any suggestions/flames? Thanks, Vikram

As you say, it is nasty. Where have you find it ? There is no driver including mx*_pins.h. At the moment, only board specific code includes the SOC specific pin header. > > Why not define the GPIO_TO_PORT macro in the driver? Maybe there was some use of the macro outside the driver in the past. I think before i.MX code was adapted to use common gpio_ functions, boards are used to write directly into the registers of the GPIO controller. I do not see any track of the macro in the current tree. So yes, we can move GPIO_ macros inside the driver. > Anyways for all its > the same 32 pins. Any suggestions/flames? It seems to me also that the defined GPIO_PORT for MX6 is wrong. arch/arm/include/asm/arch-mx6/imx-regs.h: #define GPIO_TO_PORT(number) (((number)/32)+1) Why is the port starting from 1 ? It is wrong, but really GPIO_TO_PORT() is not used anymore. Best regards, Stefano Babic
