From 85fd6d63bf2927b9da7ab1b0d46723bfdb13808c Mon Sep 17 00:00:00 2001 From: Kukjin Kim Date: Mon, 6 Feb 2012 09:38:19 +0900 Subject: ARM: S3C2410: move mach-s3c2410/* into mach-s3c24xx/ This patch moves S3C2410 stuff into mach-s3c24xx/ directory so that we can merge the s3c24 series' directories to the just one mach-s3c24xx/ directory. And this patch is including following. - re-ordered alphabetically by option text at Kconfig and Makefile - removed unused option, MACH_N35 - fixed duplcated option name, S3C2410_DMA to S3C24XX_DMA which is in plat-s3c24xx/ Cc: Ben Dooks Cc: Russell King Signed-off-by: Kukjin Kim --- arch/arm/mach-s3c2410/s3c2410.c | 206 ---------------------------------------- 1 file changed, 206 deletions(-) delete mode 100644 arch/arm/mach-s3c2410/s3c2410.c (limited to 'arch/arm/mach-s3c2410/s3c2410.c') diff --git a/arch/arm/mach-s3c2410/s3c2410.c b/arch/arm/mach-s3c2410/s3c2410.c deleted file mode 100644 index 061b6bb1a557..000000000000 --- a/arch/arm/mach-s3c2410/s3c2410.c +++ /dev/null @@ -1,206 +0,0 @@ -/* linux/arch/arm/mach-s3c2410/s3c2410.c - * - * Copyright (c) 2003-2005 Simtec Electronics - * Ben Dooks - * - * http://www.simtec.co.uk/products/EB2410ITX/ - * - * 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. -*/ - -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include - -#include -#include -#include - -#include -#include - -#include - -#include -#include - -#include -#include -#include -#include -#include -#include -#include - -#include -#include -#include - -/* Initial IO mappings */ - -static struct map_desc s3c2410_iodesc[] __initdata = { - IODESC_ENT(CLKPWR), - IODESC_ENT(TIMER), - IODESC_ENT(WATCHDOG), -}; - -/* our uart devices */ - -/* uart registration process */ - -void __init s3c2410_init_uarts(struct s3c2410_uartcfg *cfg, int no) -{ - s3c24xx_init_uartdevs("s3c2410-uart", s3c2410_uart_resources, cfg, no); -} - -/* s3c2410_map_io - * - * register the standard cpu IO areas, and any passed in from the - * machine specific initialisation. -*/ - -void __init s3c2410_map_io(void) -{ - s3c24xx_gpiocfg_default.set_pull = s3c24xx_gpio_setpull_1up; - s3c24xx_gpiocfg_default.get_pull = s3c24xx_gpio_getpull_1up; - - iotable_init(s3c2410_iodesc, ARRAY_SIZE(s3c2410_iodesc)); -} - -void __init_or_cpufreq s3c2410_setup_clocks(void) -{ - struct clk *xtal_clk; - unsigned long tmp; - unsigned long xtal; - unsigned long fclk; - unsigned long hclk; - unsigned long pclk; - - xtal_clk = clk_get(NULL, "xtal"); - xtal = clk_get_rate(xtal_clk); - clk_put(xtal_clk); - - /* now we've got our machine bits initialised, work out what - * clocks we've got */ - - fclk = s3c24xx_get_pll(__raw_readl(S3C2410_MPLLCON), xtal); - - tmp = __raw_readl(S3C2410_CLKDIVN); - - /* work out clock scalings */ - - hclk = fclk / ((tmp & S3C2410_CLKDIVN_HDIVN) ?
