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/include/linux/mfd/88pm80x.h | 4 ++-- kernel/include/linux/mfd/cros_ec.h | 15 +++++++++++++++ kernel/include/linux/mfd/samsung/s2mps11.h | 2 ++ kernel/include/linux/mfd/ti_am335x_tscadc.h | 8 ++++---- 4 files changed, 23 insertions(+), 6 deletions(-) (limited to 'kernel/include/linux/mfd') diff --git a/kernel/include/linux/mfd/88pm80x.h b/kernel/include/linux/mfd/88pm80x.h index d409ceb22..c118a7ec9 100644 --- a/kernel/include/linux/mfd/88pm80x.h +++ b/kernel/include/linux/mfd/88pm80x.h @@ -350,7 +350,7 @@ static inline int pm80x_dev_suspend(struct device *dev) int irq = platform_get_irq(pdev, 0); if (device_may_wakeup(dev)) - set_bit((1 << irq), &chip->wu_flag); + set_bit(irq, &chip->wu_flag); return 0; } @@ -362,7 +362,7 @@ static inline int pm80x_dev_resume(struct device *dev) int irq = platform_get_irq(pdev, 0); if (device_may_wakeup(dev)) - clear_bit((1 << irq), &chip->wu_flag); + clear_bit(irq, &chip->wu_flag); return 0; } diff --git a/kernel/include/linux/mfd/cros_ec.h b/kernel/include/linux/mfd/cros_ec.h index 494682ce4..3ab3cede2 100644 --- a/kernel/include/linux/mfd/cros_ec.h +++ b/kernel/include/linux/mfd/cros_ec.h @@ -223,6 +223,21 @@ int cros_ec_check_result(struct cros_ec_device *ec_dev, int cros_ec_cmd_xfer(struct cros_ec_device *ec_dev, struct cros_ec_command *msg); +/** + * cros_ec_cmd_xfer_status - Send a command to the ChromeOS EC + * + * This function is identical to cros_ec_cmd_xfer, except it returns success + * status only if both the command was transmitted successfully and the EC + * replied with success status.
