2017-04-27mfd: palmas: Reset the POWERHOLD mux during power offKeerthy1-0/+14
POWERHOLD signal has higher priority over the DEV_ON bit. So power off will not happen if the POWERHOLD is held high. Hence reset the MUX to GPIO_7 mode to release the POWERHOLD and the DEV_ON bit to take effect to power off the PMIC. PMIC Power off happens in dire situations like thermal shutdown so irrespective of the POWERHOLD setting go ahead and turn off the powerhold. Currently poweroff is broken on boards that have powerhold enabled. This fixes poweroff on those boards. Signed-off-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

Palmas device supports multiple i2c device address and the client for these addressed are created in the driver as i2c_new_dummy().

The Patch adds TPS659038 PMIC support in the palmas mfd driver. The TPS659038 has almost the same registers as of the earlier supported variants of PALMAS family such as the TWL6035. The critical differences between TPS659038 and TWL6035 being: 1) TPS659038 has nothing related to battery charging and back up battery stuff. 2) TPS659038 does not have does not have SMPS10(Boost) step up convertor. 3) TPS659038 does not have Battery detection and anything related to battery. 4) SD card detection, Battery presence detection, Vibrator, USB OTG are missing when compared to TWL6035.

2013-04-08mfd: palmas: Initialise client->of_node for dummy created clientLaxman Dewangan1-0/+1
Palmas device have three different i2c addresses. The device creates the two new dummy i2c clients for accessing the register by using primary client adapter. This new dummy i2c client have their of_node as NULL. The dummy i2c client is used for registering interrupt and on this, it creates irq domain handle. This created irq domain handle has their of_node as NULL. Now when any child of this device is registered through the DT as follows: palmas: tps65913@58 { :::::::::::::::::: #interrupt-cells = <2>; interrupt-controller; palmas_rtc { compatible = "ti,palmas-rtc"; interrupt-parent = <&palmas>; interrupts = <8 0>; }; ::::::::::;;; }; And child driver (palam-rtc in this case) get their irq number as irq = platform_get_irq(pdev, 0); The returned irq number is error in this case. The reason is that the created irq_domain handle for the palmas interrupt does not have valid node and so matching of node fails with palmas node. Hence initialising the newly dummy created client->of_node with the primary clients of_node so that irq_domain handle have proper of_node for matching.

2013-03-12mfd: palmas: Provide irq flags through DT/platform dataLaxman Dewangan1-3/+33

2012-09-14mfd: core: Push irqdomain mapping out into devicesMark Brown1-1/+2
Currently the MFD core supports remapping MFD cell interrupts using an irqdomain but only if the MFD is being instantiated using device tree and only if the device tree bindings use the pattern of registering IPs in the device tree with compatible properties. This will be actively harmful for drivers which support non-DT platforms and use this pattern for their DT bindings as it will mean that the core will silently change remapping behaviour and it is also limiting for drivers which don't do DT with this particular pattern. There is also a potential fragility if there are interrupts not associated with MFD cells and all the cells are omitted from the device tree for some reason. Instead change the code to take an IRQ domain as an optional argument, allowing drivers to take the decision about the parent domain for their interrupts. The one current user of this feature is ab8500-core, it has the domain lookup pushed out into the driver.
