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/mach-s3c64xx/dev-audio.c | 41 ++++++++++--------- kernel/arch/arm/mach-s3c64xx/include/mach/dma.h | 52 ++++++++++++------------- 2 files changed, 49 insertions(+), 44 deletions(-) (limited to 'kernel/arch/arm/mach-s3c64xx') diff --git a/kernel/arch/arm/mach-s3c64xx/dev-audio.c b/kernel/arch/arm/mach-s3c64xx/dev-audio.c index ff780a8d8..9a42736ef 100644 --- a/kernel/arch/arm/mach-s3c64xx/dev-audio.c +++ b/kernel/arch/arm/mach-s3c64xx/dev-audio.c @@ -54,12 +54,12 @@ static int s3c64xx_i2s_cfg_gpio(struct platform_device *pdev) static struct resource s3c64xx_iis0_resource[] = { [0] = DEFINE_RES_MEM(S3C64XX_PA_IIS0, SZ_256), - [1] = DEFINE_RES_DMA(DMACH_I2S0_OUT), - [2] = DEFINE_RES_DMA(DMACH_I2S0_IN), };
