* ARM i.MX51 clock: Fix regression since enabling MIPI/HSP clocksSascha Hauer2012-12-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | The MIPI/HSP clocks were recently turned on in the i.MX51 clock tree. It turned out that the system does not work properly when the MIPI/HSP clocks are enabled, but the IPU clock is disabled. This happens when IPU support is disabled. In this case the IPU clock gets disabled when the clock framework turns off unused clock in a late_initcall. This is broken since: | commit 9a2d4825a9368e018003a2732a61be063d178f67 | Author: Sascha Hauer <s.hauer@pengutronix.de> | Date: Tue Jun 5 13:53:32 2012 +0200 | | ARM i.MX5: switch IPU clk support to devicetree bindings | | The i.MX5 clk support has platform based clock bindings for the | IPU. IPU support is devicetree only, so move them over to devicetree | based bindings. Also, enable MIPI clocks which do not have a device | associated with, but still need to be enabled to do graphics on | i.MX51. This patch fixes this by setting some reserved bits in the CCM as recommended in the reference manual. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Tested-by: Shawn Guo <shawn.guo@linaro.org>

* mm: fix kernel BUG at huge_memory.c:1474!Hugh Dickins2012-12-16
| | | | | | | | | | | | | | | | | | | Andrea's autonuma-benchmark numa01 hits kernel BUG at huge_memory.c:1474! in change_huge_pmd called from change_protection from change_prot_numa from task_numa_work. That BUG, introduced in the huge zero page commit cad7f613c4d0 ("thp: change_huge_pmd(): make sure we don't try to make a page writable") was trying to verify that newprot never adds write permission to an anonymous huge page; but Automatic NUMA Balancing's 4b10e7d562c9 ("mm: mempolicy: Implement change_prot_numa() in terms of change_protection()") adds a new prot_numa path into change_huge_pmd(), which makes no use of the newprot provided, and may retain the write bit in the pmd. Just move the BUG_ON(pmd_write(entry)) up into the !prot_numa block. Signed-off-by: Hugh Dickins <hughd@google.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

We have several new drivers, most of the time coming with their sub devices drivers: - Austria Microsystem's AS3711 - Nano River's viperboard - TI's TPS80031, AM335x TS/ADC, - Realtek's MMC/memstick card reader - Nokia's retu We also got some notable cleanups and improvements: - tps6586x got converted to IRQ domains. - tps65910 and tps65090 moved to the regmap IRQ API. - STMPE is now Device Tree aware. - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ APIs and a conversion to the recently added PWM framework. - sta2x11 gained regmap support. Then the rest is mostly tiny cleanups and fixes, among which we have Mark's wm5xxx and wm8xxx patchset." Far amount of annoying but largely trivial conflicts. Many due to __devinit/exit removal, others due to one or two of the new drivers also having come in through another tree. * tag 'mfd-3.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (119 commits) mfd: tps6507x: Convert to devm_kzalloc mfd: stmpe: Update DT support for stmpe driver mfd: wm5102: Add readback of DSP status 3 register mfd: arizona: Log if we fail to create the primary IRQ domain mfd: tps80031: MFD_TPS80031 needs to select REGMAP_IRQ mfd: tps80031: Add terminating entry for tps80031_id_table mfd: sta2x11: Fix potential NULL pointer dereference in __sta2x11_mfd_mask() mfd: wm5102: Add tuning for revision B mfd: arizona: Defer patch initialistation until after first device boot mfd: tps65910: Fix wrong ack_base register mfd: tps65910: Remove unused data mfd: stmpe: Get rid of irq_invert_polarity mfd: ab8500-core: Fix invalid free of devm_ allocated data mfd: wm5102: Mark DSP memory regions as volatile mfd: wm5102: Correct default for LDO1_CONTROL_2 mfd: arizona: Register haptics devices mfd: wm8994: Make current device behaviour the default mfd: tps65090: MFD_TPS65090 needs to select REGMAP_IRQ mfd: Fix stmpe.c build when OF is not enabled mfd: jz4740-adc: Use devm_kzalloc ...

| * mfd: twl: Convert module id definitions to enumsPeter Ujfalusi2012-11-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Use enum list for the module definitions (TWL4030_MODULE_*) which will ease up future work with the IDs. At the same time group the IDs in block of five so it is easier to find the ID we are looking for (to count the number they stand for). At the same time define TWL_MODULE_LED so client drivers can switch to use it as soon as it is possible.

| * mfd: twl-core: Clean up and correct child registrationPeter Ujfalusi2012-11-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the twl child registration calls a bit more uniform by always using the SUB_CHIP_ID* define instead of the mixed use of the define and magic number. At the same time correct the following devices so they are registered for the correct parent device (i2c slave): twl4030_wdt is accessible on 0x4b address and not 0x48 twl4030_pwrbutton is accessible on 0x4b address and not 0x49 twl4030-audio is on 0x49 all the time Acked-by: Tero Kristo <t-kristo@ti.com> Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | Since the twl-core has been converted to use regmap it is no longer needed to allocate bigger buffer for data when writing to twl.

| * mfd: twl-core: Support for proper PWM driversPeter Ujfalusi2012-11-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The twl6030-pwm driver is going to be deleted since it was only able to control the Charging indicator LED on the twl6030 PMIC. The new set of drivers are going to provide support for both PWMs and PWM driven LED outputs on TWL4030 and TWL6030 PMICs. The twl-pwm driver will handle the PWMs (2 instance) while the twl-pwmled driver is to control the two LED instance on TWL4030 and to charging indicator LED (1 instance) on TWL6030.

The newer revisions of twl does not have MADC, instead they have different IP called GPADC which is not backward compatible.
