From 52f993b8e89487ec9ee15a7fb4979e0f09a45b27 Mon Sep 17 00:00:00 2001 From: Yunhong Jiang Date: Wed, 8 Mar 2017 23:13:28 -0800 Subject: Upgrade to 4.4.50-rt62 The current kernel is based on rt kernel v4.4.6-rt14. We will upgrade it to 4.4.50-rt62. The command to achieve it is: a) Clone a git repo from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git b) Get the diff between this two changesets: git diff 640eca2901f3435e616157b11379d3223a44b391 705619beeea1b0b48219a683fd1a901a86fdaf5e where the two commits are: [yjiang5@jnakajim-build linux-stable-rt]$ git show --oneline --name-only 640eca2901f3435e616157b11379d3223a44b391 640eca2901f3 v4.4.6-rt14 localversion-rt [yjiang5@jnakajim-build linux-stable-rt]$ git show --oneline --name-only 705619beeea1b0b48219a683fd1a901a86fdaf5e 705619beeea1 Linux 4.4.50-rt62 localversion-rt c) One patch has been backported thus revert the patch before applying. filterdiff -p1 -x scripts/package/Makefile ~/tmp/v4.4.6-rt14-4.4.50-rt62.diff |patch -p1 --dry-run Upstream status: backport Change-Id: I244d57a32f6066e5a5b9915f9fbf99e7bbca6e01 Signed-off-by: Yunhong Jiang --- kernel/arch/arm/common/sa1111.c | 22 +++++++++++++--------- 1 file changed, 13 insertions(+), 9 deletions(-) (limited to 'kernel/arch/arm/common') diff --git a/kernel/arch/arm/common/sa1111.c b/kernel/arch/arm/common/sa1111.c index 3d224941b..a3a9ad4dc 100644 --- a/kernel/arch/arm/common/sa1111.c +++ b/kernel/arch/arm/common/sa1111.c @@ -869,9 +869,9 @@ struct sa1111_save_data { #ifdef CONFIG_PM -static int sa1111_suspend(struct platform_device *dev, pm_message_t state) +static int sa1111_suspend_noirq(struct device *dev) { - struct sa1111 *sachip = platform_get_drvdata(dev); + struct sa1111 *sachip = dev_get_drvdata(dev); struct sa1111_save_data *save; unsigned long flags; unsigned int val; @@ -934,9 +934,9 @@ static int sa1111_suspend(struct platform_device *dev, pm_message_t state) * restored by their respective drivers, and must be called * via LDM after this function. */ -static int sa1111_resume(struct platform_device *dev) +static int sa1111_resume_noirq(struct device *dev) { - struct sa1111 *sachip = platform_get_drvdata(dev); + struct sa1111 *sachip = dev_get_drvdata(dev); struct sa1111_save_data *save; unsigned long flags, id; void __iomem *base; @@ -952,7 +952,7 @@ static int sa1111_resume(struct platform_device *dev) id = sa1111_readl(sachip->base + SA1111_SKID); if ((id & SKID_ID_MASK) != SKID_SA1111_ID) { __sa1111_remove(sachip); - platform_set_drvdata(dev, NULL); + dev_set_drvdata(dev, NULL); kfree(save); return 0; } @@ -1003,8 +1003,8 @@ static int sa1111_resume(struct platform_device *dev) } #else -#define sa1111_suspend NULL -#define sa1111_resume NULL +#define sa1111_suspend_noirq NULL +#define sa1111_resume_noirq NULL #endif static int sa1111_probe(struct platform_device *pdev) @@ -1038,6 +1038,11 @@ static int sa1111_remove(struct platform_device *pdev) return 0; } +static struct dev_pm_ops sa1111_pm_ops = { + .suspend_noirq = sa1111_suspend_noirq, + .resume_noirq = sa1111_resume_noirq, +}; + /* * Not sure if this should be on the system bus or not yet. * We really want some way to register a system device at @@ -1050,10 +1055,9 @@ static int sa1111_remove(struct platform_device *pdev) static struct platform_driver sa1111_device_driver = { .probe = sa1111_probe, .remove = sa1111_remove, - .suspend = sa1111_suspend, - .resume = sa1111_resume, .driver = { .name = "sa1111", + .pm = &sa1111_pm_ops, }, }; -- cgit 1.2.3-korg
