From 871480933a1c28f8a9fed4c4d34d06c439a7a422 Mon Sep 17 00:00:00 2001 From: Srikant Patnaik Date: Sun, 11 Jan 2015 12:28:04 +0530 Subject: Moved, renamed, and deleted files The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure. --- ANDROID_3.4.5/arch/arm/mach-davinci/pm.c | 159 ------------------------------- 1 file changed, 159 deletions(-) delete mode 100644 ANDROID_3.4.5/arch/arm/mach-davinci/pm.c (limited to 'ANDROID_3.4.5/arch/arm/mach-davinci/pm.c') diff --git a/ANDROID_3.4.5/arch/arm/mach-davinci/pm.c b/ANDROID_3.4.5/arch/arm/mach-davinci/pm.c deleted file mode 100644 index 04c49f75..00000000 --- a/ANDROID_3.4.5/arch/arm/mach-davinci/pm.c +++ /dev/null @@ -1,159 +0,0 @@ -/* - * DaVinci Power Management Routines - * - * Copyright (C) 2009 Texas Instruments, Inc. http://www.ti.com/ - * - * 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 "clock.h" - -#define DEEPSLEEP_SLEEPCOUNT_MASK 0xFFFF - -static void (*davinci_sram_suspend) (struct davinci_pm_config *); -static struct davinci_pm_config *pdata; - -static void davinci_sram_push(void *dest, void *src, unsigned int size) -{ - memcpy(dest, src, size); - flush_icache_range((unsigned long)dest, (unsigned long)(dest + size)); -} - -static void davinci_pm_suspend(void) -{ - unsigned val; - - if (pdata->cpupll_reg_base != pdata->ddrpll_reg_base) { - - /* Switch CPU PLL to bypass mode */ - val = __raw_readl(pdata->cpupll_reg_base + PLLCTL); - val &= ~(PLLCTL_PLLENSRC | PLLCTL_PLLEN); - __raw_writel(val, pdata->cpupll_reg_base + PLLCTL); - - udelay(PLL_BYPASS_TIME); - - /* Powerdown CPU PLL */ - val = __raw_readl(pdata->cpupll_reg_base + PLLCTL); - val |= PLLCTL_PLLPWRDN; - __raw_writel(val, pdata->cpupll_reg_base + PLLCTL); - } - - /* Configure sleep count in deep sleep register */ - val = __raw_readl(pdata->deepsleep_reg); - val &= ~DEEPSLEEP_SLEEPCOUNT_MASK, - val |= pdata->sleepcount; - __raw_writel(val, pdata->deepsleep_reg); - - /* System goes to sleep in this call */ - davinci_sram_suspend(pdata); - - if (pdata->cpupll_reg_base != pdata->ddrpll_reg_base) { - - /* put CPU PLL in reset */ - val = __raw_readl(pdata->cpupll_reg_base + PLLCTL); - val &= ~PLLCTL_PLLRST; - __raw_writel(val, pdata->cpupll_reg_base + PLLCTL); - - /* put CPU PLL in power down */ - val = __raw_readl(pdata->cpupll_reg_base + PLLCTL); - val &= ~PLLCTL_PLLPWRDN; - __raw_writel(val, pdata->cpupll_reg_base + PLLCTL); - - /* wait for CPU PLL reset */ - udelay(PLL_RESET_TIME); - - /* bring CPU PLL out of reset */ - val = __raw_readl(pdata->cpupll_reg_base + PLLCTL); - val |= PLLCTL_PLLRST; - __raw_writel(val, pdata->cpupll_reg_base + PLLCTL); - - /* Wait for CPU PLL to lock */ - udelay(PLL_LOCK_TIME); - - /* Remove CPU PLL from bypass mode */ - val = __raw_readl(pdata->cpupll_reg_base + PLLCTL); - val &= ~PLLCTL_PLLENSRC; - val |= PLLCTL_PLLEN; - __raw_writel(val, pdata->cpupll_reg_base + PLLCTL); - } -} - -static int davinci_pm_enter(suspend_state_t state) -{ - int ret = 0; - - switch (state) { - case PM_SUSPEND_STANDBY: - case PM_SUSPEND_MEM: - davinci_pm_suspend(); - break; - default: - ret = -EINVAL; - } - - return ret; -} - -static const struct platform_suspend_ops davinci_pm_ops = { - .enter = davinci_pm_enter, - .valid = suspend_valid_only_mem, -}; - -static int __init davinci_pm_probe(struct platform_device *pdev) -{ - pdata = pdev->dev.platform_data; - if (!pdata) { - dev_err(&pdev->dev, "cannot get platform data\n"); - return -ENOENT; - } - - davinci_sram_suspend = sram_alloc(davinci_cpu_suspend_sz, NULL); - if (!davinci_sram_suspend) { - dev_err(&pdev->dev, "cannot allocate SRAM memory\n"); - return -ENOMEM; - } - - davinci_sram_push(davinci_sram_suspend, davinci_cpu_suspend, - davinci_cpu_suspend_sz); - - suspend_set_ops(&davinci_pm_ops); - - return 0; -} - -static int __exit davinci_pm_remove(struct platform_device *pdev) -{ - sram_free(davinci_sram_suspend, davinci_cpu_suspend_sz); - return 0; -} - -static struct platform_driver davinci_pm_driver = { - .driver = { - .name = "pm-davinci", - .owner = THIS_MODULE, - }, - .remove = __exit_p(davinci_pm_remove), -}; - -static int __init davinci_pm_init(void) -{ - return platform_driver_probe(&davinci_pm_driver, davinci_pm_probe); -} -late_initcall(davinci_pm_init); -- cgit
