2013-10-23mfd: arizona: Mark missing AOD registers as volatileCharles Keepax2-2/+2
This registers ARIZONA_AOD_WKUP_AND_TRIG and ARIZONA_AOD_IRQ_RAW_STATUS contain interrupt status bits and thus should be volatile. They are correctly marked on wm5102 but not on wm5110, this patch changes this. Furthermore volatile registers don't need defaults so remove those.

2013-10-23mfd: arizona: Correct handling of device tree gpio defaultsCharles Keepax1-1/+1
When setting GPIO defaults we are required to make a distinction between writing 0x0000 to the registers and leaving them untouched. When we receive between 0x0000 and 0xFFFF (inclusive) from either Platform Data or Device Tree, we should write the provided configuration to the device. Conversely, when we receive >0xFFFF we should leave the device configuration at its default setting. This patch fixes a bug and ensures that configuration 0x0000 isn't mistakenly written when the intention was to keep the default one.

2013-10-23mfd: palmas: Fix resource leak of i2c_dummy devicesLaxman Dewangan1-6/+15
Palmas device supports multiple i2c device address and the client for these addressed are created in the driver as i2c_new_dummy(). The new devices are not getting released in error or removal path and so it is causing resource leak. Add the unregister of these newly created dummy devices to avoid resource leaks.

2013-10-23mfd: rtsx: Modify rts5249_optimize_phyWei WANG2-2/+99
In some platforms, specially Thinkpad series, rts5249 won't be initialized properly. So we need adjust some phy parameters to improve the compatibility issue. It is a little different between simulation and real chip. We have no idea about which configuration is better before tape-out. We set default settings according to simulation, but need to tune these parameters after getting the real chip. I can't explain every change in detail here. The below information is just a rough description: PHY_REG_REV: Disable internal clkreq_tx, enable rx_pwst PHY_BPCR: No change, just turn the magic number to macro definitions PHY_PCR: Change OOBS sensitivity, from 60mV to 90mV PHY_RCR2: Control charge-pump current automatically PHY_FLD4: Use TX cmu reference clock PHY_RDR: Change RXDSEL from 30nF to 1.9nF PHY_RCR1: Change the duration between adp_st and asserting cp_en from 0.32 us to 0.64us PHY_FLD3: Adjust internal timers PHY_TUNE: Fine tune the regulator12 output voltage Signed-off-by: Wei WANG <wei_wang@realsil.com.cn> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2013-10-23mfd: timberdale: Remove unnecessary pci_set_drvdata()Jingoo Han1-5/+1

2013-10-23mfd: tps6586x: Implement irq_set_wakeStephen Warren1-3/+15
rtc-tps6586x calls enable/disable_irq_wake() during suspend/resume. Since the main tps6586x irq_chip doesn't implement .irq_set_wake, this causes the RTC's enable_irq_wake() to fail, and the disable_irq_wake() to spew a WARN about unbalanced wake disable. Solve this by implementing .irq_set_wake. Also, I assume that enable_irq_wake() shouldn't be called unconditionally in tps6586x_irq_init(), since this is now triggered by IRQ children setting up their cascaded IRQs for wake. So, remove that.
