This series removes unused setup-code of the s3c24xx spi driver.
It has no current in kernel users and also no development activity trying
to change this. I also checked the upstream git of the only board including
the spi.h file (the gta02 at http://git.openmoko.org). The setup calls
are also not used there.
I recall a thread some time back talking about removing the spi-s3c24xx
driver altogether, but as current linux-next still carries the driver
I'm not sure what became of it. So this series does the next smaller thing.

There was also no activity in this regard through the last kernel releases, so it seems this situation will not change in the future. Therefore this patch removes this seemingly dead code.

As your cleanup-s3c24xx branch is not pushed out yet, could you please replace it with this one, which adds the forgotten file. arch/arm/mach-s3c2410/include/mach/spi.h | 27 --------------------------- arch/arm/mach-s3c2440/mach-gta02.c | 2 +- drivers/spi/spi-s3c24xx.c | 2 +- include/linux/spi/s3c24xx.h | 26 ++++++++++++++++++++++++++ 4 files changed, 28 insertions(+), 29 deletions(-) delete mode 100644 arch/arm/mach-s3c2410/include/mach/spi.h create mode 100644 include/linux/spi/s3c24xx.h diff --git a/arch/arm/mach-s3c2410/include/mach/spi.h b/arch/arm/mach-s3c2410/include/mach/spi.h deleted file mode 100644 index 2a686c0..0000000 --- a/arch/arm/mach-s3c2410/include/mach/spi.h +++ /dev/null @@ -1,27 +0,0 @@ -/* arch/arm/mach-s3c2410/include/mach/spi.h - * - * Copyright (c) 2006 Simtec Electronics - * Ben Dooks <ben@simtec.co.uk> - * - * S3C2410 - SPI Controller platform_device info - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License version 2 as - * published by the Free Software Foundation. -*/ - -#ifndef __ASM_ARCH_SPI_H -#define __ASM_ARCH_SPI_H __FILE__ - -struct s3c2410_spi_info { - int pin_cs; /* simple gpio cs */ - unsigned int num_cs; /* total chipselects */ - int bus_num; /* bus number to use. */ - - unsigned int use_fiq:1; /* use fiq */ - - void (*gpio_setup)(struct s3c2410_spi_info *spi, int enable); - void (*set_cs)(struct s3c2410_spi_info *spi, int cs, int pol); -}; - -#endif /* __ASM_ARCH_SPI_H */ diff --git a/arch/arm/mach-s3c2440/mach-gta02.c b/arch/arm/mach-s3c2440/mach-gta02.c index 5859e60..cf270f5 100644 --- a/arch/arm/mach-s3c2440/mach-gta02.c +++ b/arch/arm/mach-s3c2440/mach-gta02.c @@ -38,6 +38,7 @@ #include <linux/platform_device.h> #include <linux/serial_core.h> #include <linux/spi/spi.h> +#include <linux/spi/s3c24xx.h> #include <linux/mmc/host.h> @@ -73,7 +74,6 @@ #include <mach/regs-gpioj.h> #include <mach/fb.h> -#include <mach/spi.h> #include <plat/usb-control.h> #include <mach/regs-mem.h> #include <mach/hardware.h> diff --git a/drivers/spi/spi-s3c24xx.c b/drivers/spi/spi-s3c24xx.c index fc06453..8ee7d79 100644 --- a/drivers/spi/spi-s3c24xx.c +++ b/drivers/spi/spi-s3c24xx.c @@ -24,10 +24,10 @@ #include <linux/spi/spi.h> #include <linux/spi/spi_bitbang.h> +#include <linux/spi/s3c24xx.h> #include <linux/module.h> #include <plat/regs-spi.h> -#include <mach/spi.h> #include <plat/fiq.h> #include <asm/fiq.h> diff --git a/include/linux/spi/s3c24xx.h b/include/linux/spi/s3c24xx.h new file mode 100644 index 0000000..c23b923 --- /dev/null +++ b/include/linux/spi/s3c24xx.h @@ -0,0 +1,26 @@ +/* + * Copyright (c) 2006 Simtec Electronics + * Ben Dooks <ben@simtec.co.uk> + * + * S3C2410 - SPI Controller platform_device info + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. +*/ + +#ifndef __LINUX_SPI_S3C24XX_H +#define __LINUX_SPI_S3C24XX_H __FILE__ + +struct s3c2410_spi_info { + int pin_cs; /* simple gpio cs */ + unsigned int num_cs; /* total chipselects */ + int bus_num; /* bus number to use. */ + + unsigned int use_fiq:1; /* use fiq */ + + void (*gpio_setup)(struct s3c2410_spi_info *spi, int enable); + void (*set_cs)(struct s3c2410_spi_info *spi, int cs, int pol); +}; + +#endif /* __LINUX_SPI_S3C24XX_H */ -- 1.7.5.4 ^ permalink raw reply related [flat|nested] 6+ messages in thread
