[PATCH] ARM: EXYNOS4: convert boot_params to atag_offset

by Tushar Behera

Based on "ARM: introduce atag_offset to replace boot_params" by Nicolas Pitre (2bb9839e312ed55a6d5824ffa6077ce3d7d63b1e). Since boot_params variable is deleted from machine_desc, the variable is modified in the newer board files.

Bootchart results

by Paul Larson

I started working on a results view in LAVA for the bootchart results since they are now part of the daily runs. This is using a partial copy of the data I have locally, so please don't concern yourself too much with the actual data in it. A couple of things to point out: 1. legend is not placed well, that's something I'm not yet sure how to fix as my javascript-fu is lacking here (zyga, any ideas on this?) 2. The set of results here is not very large. That's adjustable and when it's using live data, should have a lot more data points to better see trends 3. This is purposefully restricted to a single board. We are not running benchmarks in a controlled enough manner as to make comparison of boards to one another reasonable, nor is it encouraged due to the collaborative nature of Linaro. In particular I'm looking for opinions on how it would be most useful to display this data. This view shows all 4 image types on a single chart. I did a previous version that had them separate. Is there a preference? It would also be easy to do both on the same page, but perhaps a bit redundant. Thanks, Paul Larson

[PATCH v2 0/3] mmc: rectify boot param option for fault injection

by Per Forlin

Akinobu Mita reported that the boot option for mmc fault injection is never compiled in due to a fauly "ifdef KERNEL" that is never set. A correct ifdef would be "ifndef MODULE". This patch set adds a module_param_cb() and thereby no ifndef MODULE is needed. Using a module_param makes it possible to pass default fault attributes for external modules too. This patch set is for 3.2 Change log: v2 - use module_param_cb() to set default fault attributes - fix spelling of documentation in patch #3 Per Forlin (3): fault-inject: export setup_fault_attr() mmc: add module param to set fault injection attributes fault-injection: update documentation with the mmc module param Documentation/fault-injection/fault-injection.txt | 2 +- drivers/mmc/core/debugfs.c | 38 +++++++++++---------- lib/fault-inject.c | 3 +- 3 files changed, 23 insertions(+), 20 deletions(-) -- 1.7.4.1

[PATCH v9 0/3] mmc: make fault injection available for MMC IO

by Per Forlin

From: Per Forlin <per.forlin(a)linaro.org> change log: v2 - Resolve build issue in mmc core.c due to multiple init_module by removing the fault inject module. - Export fault injection functions to make them available for modules - Update fault injection documentation on MMC IO v3 - add function descriptions in core.c - use export GPL for fault injection functions v4 - make the fault_attr per host. This prepares for upcoming patch from Akinobu that adds support for creating debugfs entries in arbitrary directory. v5 - Make use of fault_create_debugfs_attr() in Akinobu's patch "fault-injection: add ability to export fault_attr in...". v6 - Fix typo in commit message in patch "export fault injection functions" v7 - Don't compile in boot param setup function if mmc-core is built as module. v8 - Update fault injection documentation. Add fail_mmc_request to boot option section. v9 - remove ifdef around include files and inline empty function, comments from Linus Walleij.

[PATCH 2/4 v6] pinmux: add a driver for the U300 pinmux

by Linus Walleij

From: Linus Walleij <linus.walleij(a)linaro.org> This adds a driver for the U300 pinmux portions of the system controller "SYSCON". It also serves as an example of how to use the pinmux subsystem. This driver also houses the platform data for the only supported platform. Signed-off-by: Linus Walleij <linus.walleij(a)linaro.org> --- ChangeLog v5->v6: - Adjust driver to use the new pin group concept so that it serves as a good illustration of how to use groups. - Provide pinmux functions separate from groups, add a group association field to the U300 pinmux struct and provide a callback function to retrieve the available groups per function. - Adjust to various other changes like the per-pin debug print function being part of pinctrl_ops rather than the pinmux_ops. --- arch/arm/mach-u300/core.c | 26 ++ drivers/pinctrl/Kconfig | 7 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/pinmux-u300.c | 932 +++++++++++++++++++++++++++++++++++++++++ drivers/pinctrl/pinmux-u300.h | 141 +++++++ 5 files changed, 1107 insertions(+), 0 deletions(-) create mode 100644 drivers/pinctrl/pinmux-u300.c create mode 100644 drivers/pinctrl/pinmux-u300.h diff --git a/arch/arm/mach-u300/core.c b/arch/arm/mach-u300/core.c index 399c89f..2020bf9 100644 --- a/arch/arm/mach-u300/core.c +++ b/arch/arm/mach-u300/core.c @@ -25,6 +25,7 @@ #include <linux/err.h> #include <linux/mtd/nand.h> #include <linux/mtd/fsmc.h> +#include <linux/pinctrl/machine.h> #include <asm/types.h> #include <asm/setup.h> @@ -1630,6 +1631,27 @@ static struct platform_device dma_device = { }, }; +static struct platform_device pinmux_device = { + .name = "pinmux-u300", + .id = -1, + .num_resources = ARRAY_SIZE(pinmux_resources), + .resource = pinmux_resources, +}; + +/* Padmux settings */ +static struct pinmux_map u300_padmux_map[] = { + /* anonymous map for chip power */ + { + .name = "power", + .ctrl_dev_name = "pinctrl.0", + .function = "power", + .dev_name = NULL, + }, + PINMUX_MAP_PRIMARY("mmc0", "mmci"), + PINMUX_MAP_PRIMARY("spi0", "pl022"), + PINMUX_MAP_PRIMARY("uart0", "uart0"), +}; + /* * Notice that AMBA devices are initialized before platform devices. * @@ -1828,6 +1850,10 @@ void __init u300_init_devices(void) u300_assign_physmem(); + /* Initialize pinmuxing */ + pinmux_register_mappings(u300_padmux_map, + ARRAY_SIZE(u300_padmux_map)); + /* Register subdevices on the I2C buses */ u300_i2c_register_board_devices(); diff --git a/drivers/pinctrl/Kconfig b/drivers/pinctrl/Kconfig index adb0be0..fdeca2f 100644 --- a/drivers/pinctrl/Kconfig +++ b/drivers/pinctrl/Kconfig @@ -26,4 +26,11 @@ config DEBUG_PINCTRL help Say Y here to add some extra checks and diagnostics to PINCTRL calls. +config PINMUX_U300 + bool "U300 pinmux driver" + depends on ARCH_U300 + select PINMUX + help + Say Y here to enable the U300 pinmux driver + endif diff --git a/drivers/pinctrl/Makefile b/drivers/pinctrl/Makefile index 596ce9f..63d4241 100644 --- a/drivers/pinctrl/Makefile +++ b/drivers/pinctrl/Makefile @@ -4,3 +4,4 @@ ccflags-$(CONFIG_DEBUG_PINMUX) += -DDEBUG obj-$(CONFIG_PINCTRL) += core.o obj-$(CONFIG_PINMUX) += pinmux.o +obj-$(CONFIG_PINMUX_U300) += pinmux-u300.o diff --git a/drivers/pinctrl/pinmux-u300.c b/drivers/pinctrl/pinmux-u300.c new file mode 100644 index 0000000..48e1ec7 --- /dev/null +++ b/drivers/pinctrl/pinmux-u300.c @@ -0,0 +1,932 @@ +/* + * Driver for the U300 pin controller + * + * Based on the original U300 padmux functions + * Copyright (C) 2009-2011 ST-Ericsson AB + * Author: Martin Persson <martin.persson(a)stericsson.com> + * Author: Linus Walleij <linus.walleij(a)linaro.org> + * + * The DB3350 design and control registers are oriented around pads rather than + * pins, so we enumerate the pads we can mux rather than actual pins.

[PATCH 0/3] mmc: rectify boot param option for fault injection

by Per Forlin

Akinobu Mita reported that the boot option for mmc fault injection is never compiled in due to a fauly "ifdef KERNEL" that is never set. A correct ifdef would be "ifndef MODULE". Akinobu suggested to use a module param instead. This patch set is for 3.2 Per Forlin (3): fault-inject: export setup_fault_attr() mmc: add module param to set fault injection attributes fault-injection: update documenation with the mmc module param Documentation/fault-injection/fault-injection.txt | 2 +- drivers/mmc/core/debugfs.c | 29 ++++++++------------- lib/fault-inject.c | 3 +- 3 files changed, 14 insertions(+), 20 deletions(-) -- 1.7.4.1
