[PATCH v6] clk: mediatek: Export CPU mux clocks for CPU frequency control

by Pi-Cheng Chen

From: "pi-cheng.chen" <pi-cheng.chen(a)linaro.org> This patch adds CPU mux clocks which are used by Mediatek cpufreq driver for intermediate clock source switching. Signed-off-by: Pi-Cheng Chen <pi-cheng.chen(a)linaro.org> --- Changes in v6: - Relace __clk_get_num_parents with clk_hw_get_num_parents to reflect API change Changes in v5: - Replace __initdata with __initconst to fix compiling error Changes in v4: - Fix some minor issues for v3 - Rebase to the patch that adds 13mhz clock for MT8173[1] Changes in v3: - Rebase to 4.2-rc1 - Fix some issues of v2 Changes in v2: - Remove use of .determine_rate callback --- drivers/clk/mediatek/Makefile | 2 +- drivers/clk/mediatek/clk-cpumux.c | 127 +++++++++++++++++++++++++++++++++ drivers/clk/mediatek/clk-cpumux.h | 22 ++++++ drivers/clk/mediatek/clk-mt8173.c | 23 ++++++ include/dt-bindings/clock/mt8173-clk.h | 4 +- 5 files changed, 176 insertions(+), 2 deletions(-) create mode 100644 drivers/clk/mediatek/clk-cpumux.c create mode 100644 drivers/clk/mediatek/clk-cpumux.h diff --git a/drivers/clk/mediatek/Makefile b/drivers/clk/mediatek/Makefile index 8e4b2a4..299917a 100644 --- a/drivers/clk/mediatek/Makefile +++ b/drivers/clk/mediatek/Makefile @@ -1,4 +1,4 @@ -obj-y += clk-mtk.o clk-pll.o clk-gate.o +obj-y += clk-mtk.o clk-pll.o clk-gate.o clk-cpumux.o obj-$(CONFIG_RESET_CONTROLLER) += reset.o obj-y += clk-mt8135.o obj-y += clk-mt8173.o diff --git a/drivers/clk/mediatek/clk-cpumux.c b/drivers/clk/mediatek/clk-cpumux.c new file mode 100644 index 0000000..91b5238 --- /dev/null +++ b/drivers/clk/mediatek/clk-cpumux.c @@ -0,0 +1,127 @@ +/* + * Copyright (c) 2015 Linaro Ltd. + * Author: Pi-Cheng Chen <pi-cheng.chen(a)linaro.org> + * + * 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. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

[PATCH v1 0/2] iio: Add parent_trigger attribute to triggers

by Benjamin Gaignard

Thoses patches add parent_trigger attribute to IIO triggers. The goal is to allow triggers to use triggers like is this done for iio devices. With this patch it will be possible to chain triggers, for example stm32 triggers could be used as clock of an other triggers: echo "tim1_trgo" > trigger0/parent_trigger. Similary to what already exist to validate a device, a new (optional) validate_trigger function is added in iio_trigger structure and should be filled by drivers.

Kernel with GCOV does not boot after picking up lsk-v4.4-16.11

by Lixin Yao

We believe we have found a GCOV regression issue in the 4.4 based kernel. Our Linaro kernel based on lsk-v4.4-16.09 works after enabling GCOV with following configurations: CONFIG_GCOV_KERNEL=y CONFIG_GCOV_PROFILE_ALL=y CONFIG_GCOV_FORMAT_AUTODETECT=y After merging in lsk-v4.4-16.11, the kernel with above GCOV configurations does not boot. We looked at the Linaro commit history and tried gradual merging, and determined the problem happens between these two commits: aa9b1a6affdc4da75d95d40cf83167351b9848b4 (this is bad) b67b1ab417fe73a632583cdd7b710e4450c9d4ec (this is good) There are 12 commits in between. We noticed almost all changes in the commits are in KVM area. So we tried building our kernel with GCOV enabled and with CONFIG_KVM removed. The kernel boots fine. We think there is an issue with KVM in lsk-v4.4-16.11 if GCOV is enabled. And the issue was probably introduced in the 12 commits. We would be grateful if someone can verify the existence of the issue and provide a fix. We are more than happy to test any patches. Thank you. Lixin Yao
