Devices that use spitz_pm.c will fail to resume from STR (Suspend To Ram) when the charger plug is inserted or removed when a device is in STR mode. The culprit is a misconfigured gpio line - GPIO18. GPIO18 should be configured as a regular GPIO input but it gets configured as an alternate function GPIO18_RDY. And then later in postsuspend() it gets configured as a regular GPIO18 input line. Fix this by removing the GPIO18_RDY configuration so that GPIO18 only gets configured as a regular gpio input.

Recent changes to PXA PWM support changed the PXA27X PWM device numbering scheme. The linux-3.5 PXA PWM driver followed the hardware numbering scheme for the 4 PWMs, while the linux-3.6-rc1 PXA PWM driver has adopted a linear numbering scheme: Address Hardware 3.5 pwm_id 3.6-rc1 pwm_id 0x40b00000 PWM0 0 0 0x40b00010 PWM2 2 1 0x40c00000 PWM1 1 2 0x40c00010 PWM3 3 3 The hx4700 backlight uses PWM1 at 0x40c00000. Consequently the pwm_id must be changed from 1 to 2. This patch fixes the backlight PWM device number and at the same time moves from the legacy PWM API (pwm_id) to the new PWM API (pwm_lookup).

As suggested by Andrew Morton: This is a pet peeve of mine. Any time there's a long list of items (header file inclusions, kconfig entries, array initalisers, etc) and someone wants to add a new item, they *always* go and stick it at the end of the list. Guys, don't do this. Either put the new item into a randomly-chosen position or, probably better, alphanumerically sort the list. lets sort all our select statements alphanumerically. This commit was created by the following perl: while (<>) { while (/\\\s*$/) { $_ .= <>; } undef %selects if /^\s*config\s+/; if (/^\s+select\s+(\w+).*/) { if (defined($selects{$1})) { if ($selects{$1} eq $_) { print STDERR "Warning: removing duplicated $1 entry\n"; } else { print STDERR "Error: $1 differently selected\n". "\tOld: $selects{$1}\n". "\tNew: $_\n"; exit 1; } } $selects{$1} = $_; next; } if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or /^endif/ or /^endchoice/)) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } undef %selects; } print; } if (%selects) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } } It found two duplicates: Warning: removing duplicated S5P_SETUP_MIPIPHY entry Warning: removing duplicated HARDIRQS_SW_RESEND entry and they are identical duplicates, hence the shrinkage in the diffstat of two lines.

The symbol "GPIO24_SSP1_SFRM" is defined in both mfp-pxa27x.h and mfp-pxa25x.h. Since the macro is not actually used in the cm-x2xx.c file, but it includes both headers, a safe workaround should be to just undefine it from the .c file. This is a bit hacky and the headers should be fixed to not both define it, but for now it gets us around an annoying warning. Without this patch, building cm_x2xx_defconfig results in: In file included from arch/arm/mach-pxa/include/mach-pxa/pxa27x.h:7:0, from arch/arm/mach-pxa/cm-x2xx.c:25: arch/arm/mach-pxa/include/mach-pxa/mfp-pxa27x.h:215:0: warning: "GPIO24_SSP1_SFRM" redefined [enabled by default] arch/arm/mach-pxa/include/mach-pxa/mfp-pxa25x.h:111:0: note: this is the location of the previous definition Signed-off-by: NArnd Bergmann <arnd@arndb.de> Acked-by: NIgor Grinberg <grinberg@compulab.co.il> Cc: Haojian Zhuang <haojian.zhuang@gmail.com> Cc: Mike Rapoport <mike@compulab.co.il>

The arm_pmu_type enumeration was initially introduced to identify different PMU types in the system, the usual one being that on the CPU (ARM_PMU_DEVICE_CPU). With the removal of the PMU reservation code and the introduction of devicetree bindings for the CPU PMU, the enumeration is no longer required. This patch removes the enumeration and updates the various CPU PMU platform devices so that they no longer pass an .id field referring to identify the PMU type.

Properly register on-chip interrupt using the irqdomain logic. The number of interrupts is taken from the devicetree node. That includes the following changes: - cpu_has_ipr() was converted from an inline function to a static bool variable, so it can be set using the "marvell,intc-priority" property inside the device node of the tree. - IRQ_BASE was converted from a macro to a runtime variable so that it can be initialized dynamically from the DT init code. - irq_base() now uses pxa_irq_base and just adds an offset. Hence, there are now no compile-time fixed values used in case of DT initialization.

The EETI touchscreen asserts its IRQ line as soon as it has data in its internal buffers. The line is automatically deasserted once all data has been read via I2C. Hence, the driver has to monitor the GPIO line and cannot simply rely on the interrupt handler reception. In the current implementation of the driver, irq_to_gpio() is used to determine the GPIO number from the i2c_client's IRQ value. As irq_to_gpio() is not available on all platforms, this patch changes this and makes the driver ignore the passed in IRQ. Instead, a GPIO is added to the platform_data struct and gpio_to_irq is used to derive the IRQ from that GPIO. If this fails, bail out. The driver is only able to work in environments where the touchscreen GPIO can be mapped to an IRQ. Without this patch, building raumfeld_defconfig results in: drivers/input/touchscreen/eeti_ts.c: In function 'eeti_ts_irq_active': drivers/input/touchscreen/eeti_ts.c:65:2: error: implicit declaration of function 'irq_to_gpio' [-Werror=implicit-function-declaration] Signed-off-by: NDaniel Mack <zonque@gmail.com> Signed-off-by: NArnd Bergmann <arnd@arndb.de> Cc: stable@vger.kernel.org (v3.2+) Cc: Dmitry Torokhov <dmitry.torokhov@gmail.com> Cc: Sven Neumann <s.neumann@raumfeld.com> Cc: linux-input@vger.kernel.org Cc: Haojian Zhuang <haojian.zhuang@gmail.com>

Basic suspend/resume is fixed by ensuring that the PGSR registers are set correctly before sleep mode is entered. In particular four of the active low resets need to be driven high while in sleep mode, otherwise the unit resets itself instead of suspending.

Most PCI implementations use the standard PCI swizzle function, which handles the well defined behaviour of PCI-to-PCI bridges which can be found on cards (eg, four port ethernet cards.) Rather than having almost every platform specify the standard swizzle function, make this the default when no swizzle function is supplied. Therefore, a swizzle function only needs to be provided when there is something exceptional which needs to be handled. This gets rid of the swizzle initializer from 47 files, and leaves us with just two platforms specifying a swizzle function: ARM Integrator and Chalice CATS.

Pins configured as input and have MFP_LPM_DRIVE_* flag set, can have a wrong output value for some period of time (spike) during the suspend sequence. This can happen because the direction of the pins (GPDR) is set by software and the output level is set by hardware (PGSR) at a later stage. Fix the above potential bug by setting the output levels first. Also save the actual levels of the pins before the suspend and restore them after the resume, but before the direction settings take place, so the same bug as described above will not happen in the resume sequence.

Pins that have MFP_LPM_KEEP_OUTPUT set and are configured for output must retain the output state in low power mode. Currently, the pin direction configuration is overrided with values in gpdr_lpm[] array and do not obey the MFP_LPM_KEEP_OUTPUT setting. Fix the above bug and add some documentation to clarify the MFP_LPM_KEEP_OUTPUT setting purpose.
