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/drivers/regulator/tps65910-regulator.c | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'kernel/drivers/regulator/tps65910-regulator.c') diff --git a/kernel/drivers/regulator/tps65910-regulator.c b/kernel/drivers/regulator/tps65910-regulator.c index fb991ec76..696116ebd 100644 --- a/kernel/drivers/regulator/tps65910-regulator.c +++ b/kernel/drivers/regulator/tps65910-regulator.c @@ -1111,6 +1111,12 @@ static int tps65910_probe(struct platform_device *pdev) pmic->num_regulators = ARRAY_SIZE(tps65910_regs); pmic->ext_sleep_control = tps65910_ext_sleep_control; info = tps65910_regs; + /* Work around silicon erratum SWCZ010: output programmed + * voltage level can go higher than expected or crash + * Workaround: use no synchronization of DCDC clocks + */ + tps65910_reg_clear_bits(pmic->mfd, TPS65910_DCDCCTRL, + DCDCCTRL_DCDCCKSYNC_MASK); break; case TPS65911: pmic->get_ctrl_reg = &tps65911_get_ctrl_register; -- cgit 1.2.3-korg
