2016-04-30ARM: pxa: activate pinctrl for device-tree machinesRobert Jarzmik1-0/+2
Pincontrol is not yet ready for all PXA platforms. For example, a legacy platform, if PINCTRL was activated, will fail its calls to gpio_request() or gpio_direction_output(), as the pinctrl driver might not be available, such as for pxa25x and pxa3xx. As a step forward, activate pincontrol for all device-tree available machines, ie. pxa27x device-tree based and pxa3xx device-tree based. If it appears later that pincontrol is also required for legacy platforms and if the mfp->pinctrl conversion can be achieved, then PINCTRL will be activated for the whole PXA architecture.

2016-04-09device property: don't bother the drivers with struct property_setHeikki Krogerus1-8/+4
Since device_add_property_set() now always takes a copy of the property_set, and also since the fwnode type is always hard coded to be FWNODE_PDATA, there is no need for the drivers to deliver the entire struct property_set. The function can just create the instance of it on its own and bind the properties from the drivers to it on the spot. This renames device_add_property_set() to device_add_properties(). The function now takes struct property_entry as its parameter instead of struct property_set.

2016-03-16ARM: pxa/raumfeld: use PROPERTY_ENTRY_INTEGER to define propsArnd Bergmann1-11/+4
gcc-6.0 notices that the use of the property_entry in this file that was recently introduced cannot work right, as we initialize the wrong field: raumfeld.c:387:3: error: the address of 'raumfeld_rotary_encoder_steps' will always evaluate as 'true' [-Werror=address] DEV_PROP_U32, 1, &raumfeld_rotary_encoder_steps, }, ^~~~~~~~~~~~ raumfeld.c:389:3: error: the address of 'raumfeld_rotary_encoder_axis' will always evaluate as 'true' [-Werror=address] DEV_PROP_U32, 1, &raumfeld_rotary_encoder_axis, }, ^~~~~~~~~~~~ raumfeld.c:391:3: error: the address of 'raumfeld_rotary_encoder_relative_axis' will always evaluate as 'true' [-Werror=address] DEV_PROP_U32, 1, &raumfeld_rotary_encoder_relative_axis, }, ^~~~~~~~~~~~ The problem appears to stem from relying on an old definition of 'struct property', but it has changed several times since the code could have last been correct. This changes the code to use the PROPERTY_ENTRY_INTEGER() macro instead, which works fine for the current definition and is a safer way of doing the initialization.

ixp4xx and pxa25x both use this driver and provide a slightly different set of register definitions for it. Aside from that, the definition in the ixp4xx-regs.h header conflicts with the on in the pxa27x device driver when compile-testing that: In file included from ../drivers/usb/gadget/udc/pxa27x_udc.c:37:0: ../drivers/usb/gadget/udc/pxa27x_udc.h:26:0: warning: "UDCCR" redefined #define UDCCR 0x0000 /* UDC Control Register */ ^ In file included from ../arch/arm/mach-ixp4xx/include/mach/hardware.h:27:0, from ../arch/arm/mach-ixp4xx/include/mach/io.h:18, from ../arch/arm/include/asm/io.h:194, from ../include/linux/io.h:25, from ../include/linux/irq.h:24, from ../drivers/usb/gadget/udc/pxa27x_udc.c:23: ../arch/arm/mach-ixp4xx/include/mach/ixp4xx-regs.h:415:0: note: this is the location of the previous definition #define UDCCR IXP4XX_USB_REG(IXP4XX_USB_BASE_VIRT+0x0000) This addresses both issues by moving all the definitions into the pxa25x_udc driver itself.

This aids improved helpers and should make certain abstractions easier in the future. Also causes a lot of churn, helped along by some automated code transformations - add more core support for detecting (and "correcting") bitflips in erased pages; requires opt-in by drivers, but at least we kill a few bad implementations and hopefully stave off future ones - pxa3xx_nand: cleanups, a few fixes, and PM improvements - new JZ4780 NAND driver SPI NOR: - provide default erase function, for controllers that just want to send the SECTOR_ERASE command directly - fix some module auto-loading issues with device tree ("jedec,spi-nor") - error handling fixes - new Mediatek QSPI flash driver Other: - cfi: force valid geometry Kconfig (finally!)

The 'fixes' branch contains d5d4fdd86f57 ("irqchip/versatile-fpga: Fix PCI IRQ mapping on Versatile PB") that is required for booting the versatile platform prior to the rework in this branch, but including both causes a build-time error. I'm doing an evil merge here to pull in the fixes branch so we have that commit included but at the same time revert the trivial change.

2015-12-16ARM: pxa: mark ezx structures as __maybe_unusedArnd Bergmann1-5/+5
The ezx platform contains multiple machine descriptors, but not all of them use all of the data structures, and it's possible to disable all of the machines, which produces some harmless warnings: mach-pxa/ezx.c:53:26: warning: 'ezx_pwm_lookup' defined but not used [-Wunused-variable] mach-pxa/ezx.c:86:31: warning: 'ezx_fb_info_1' defined but not used [-Wunused-variable] mach-pxa/ezx.c:107:31: warning: 'ezx_fb_info_2' defined but not used [-Wunused-variable] mach-pxa/ezx.c:113:32: warning: 'ezx_devices' defined but not used [-Wunused-variable] mach-pxa/ezx.c:117:22: warning: 'ezx_pin_config' defined but not used [-Wunused-variable] This marks all those structures as __maybe_unused to avoid the warnings. Obviously a configuration that contains the ezx platform but no specific model is a bit silly, but it should not cause compile-time warnings.

In an old commit, we worked around the duplicate definition of GPIO24_SSP1_SFRM in cm-x2xx.c, which includes files for both pxa25x and pxa27x. Apparently the problem has come back and we now have four additional duplicate symbols that cause warnings: In file included from /git/arm-soc/arch/arm/mach-pxa/pxa27x.h:7:0, from /git/arm-soc/arch/arm/mach-pxa/cm-x2xx.c:27: /git/arm-soc/arch/arm/mach-pxa/mfp-pxa27x.h:21:0: warning: "GPIO86_GPIO" redefined #define GPIO86_GPIO MFP_CFG_IN(GPIO86, AF0) This uses the same hack as before and undefines all symbols that are defined more than once.

2015-11-17[media] include/media: split I2C headers from V4L2 coreMauro Carvalho Chehab1-1/+1
Currently, include/media is messy, as it contains both the V4L2 core headers and some driver-specific headers on the same place. That makes harder to identify what core headers should be documented and what headers belong to I2C drivers that are included only by bridge/main drivers that would require the functions provided by them. Let's move those i2c specific files to its own subdirectory. The files to move were produced via the following script: mkdir include/media/i2c (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done) (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done) for i in include/media/*.h; do n=`basename $i`; (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done And the references corrected via this script: MAIN_DIR="media/" PREV_DIR="media/" DIRS="i2c/" echo "Checking affected files" >&2 for i in $DIRS; do for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do n=`basename $j` git grep -l $n done done|sort|uniq >files && ( echo "Handling files..." >&2; echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\"; ( cd include/$MAIN_DIR; for j in $DIRS; do for i in $(ls $j); do echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done"; ); echo "Handling documentation..." >&2; echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\"; ( cd include/$MAIN_DIR; for j in $DIRS; do for i in $(ls $j); do echo " perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done" ); ) >script && . ./script Merged Sakari Ailus patch that moves smiapp.h to include/media/i2c.

2015-10-16ARM: pxa: remove incorrect __init annotation on pxa27x_set_pwrmodeArnd Bergmann2-2/+2
The z2 machine calls pxa27x_set_pwrmode() in order to power off the machine, but this function gets discarded early at boot because it is marked __init, as pointed out by kbuild: WARNING: vmlinux.o(.text+0x145c4): Section mismatch in reference from the function z2_power_off() to the function .init.text:pxa27x_set_pwrmode() The function z2_power_off() references the function __init pxa27x_set_pwrmode(). This is often because z2_power_off lacks a __init annotation or the annotation of pxa27x_set_pwrmode is wrong. This removes the __init section modifier to fix rebooting and the build error.
