Converting the gpio driver of tps6586x to a platform driver in place of registering the gpio through core driver. The motivation of the change is: - This is inline with the mfd drivers implementation. - This will move the related gpio support to gpio driver folder where all gpio related drivers are available. This will be easy the maintenance and enhancement is anything done for gpio. - The gpio functionality can be selected through config variable.

Before we can use any domain allocated IRQ, we need to first create a map between the Hardware IRQ (hwirq) and the Linux Virtual IRQ (virq). We do this with a helper function provided by the AB8500 IRQ domain controller called ab8500_irq_get_virq(). We need to do this for both IRQs which the Power-On-Key driver uses; one for button press, the other for button depress.

This was introduced in commit 876989d5 (mfd: Add device tree probe support for mc13xxx) for spi and later while introducing support for i2c copied to the i2c driver. Modifying driver details is very strange, for example probing an mc13892 device (instantiated via dt) removes the driver's ability to handle (traditionally probed) mc13783 devices in this case. I'm not aware of any problems that make this hack necessary and if there were some, they'd have to be fixed in the spi/i2c core, not in a driver.

This fixes below section mismatch warning: LD drivers/mfd/built-in.o WARNING: drivers/mfd/built-in.o(.devinit.text+0x46c): Section mismatch in reference from the function pm800_probe() to the function .devexit.text:pm80x_deinit() The function __devinit pm800_probe() references a function __devexit pm80x_deinit(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __devexit annotation of pm80x_deinit() so it may be used outside an exit section.

device_init_wakeup uses the dev_name() of the device to set the name of the wakeup_source which appears in /sys/kernel/debug/wakeup_sources. For a platform device, that name is not set until platform_device_add calls dev_set_name. So the call to device_init_wakeup() must be after the call to platform_device_add(). Making this change causes correct names to appear in the wakeup_sources file. Signed-off-by: NNeilBrown <neilb@suse.de> Acked-by: NRafael J.

in hw design, 800 is mainly for pmic control, while 805 for audio. but there are 3 registers which controls class D speaker property, and they are defined in 800 i2c client domain. so 805 codec driver needs to use 800 i2c client to access class D speaker reg for audio path management. so add this workaround for the purpose to let 805 access 800 i2c in some scenario.

88PM800 and 88PM805 are two discrete chips used for power management. Hardware designer can use them together or only one of them according to requirement. 88pm80x.c provides common i2c driver handling for both 800 and 805, such as i2c_driver init, regmap init, read/write api etc. 88pm800.c handles specifically for 800, such as chip init, irq init/handle, mfd device register, including rtc, onkey, regulator( to be add later) etc. besides that, 800 has three i2c device, one regular i2c client, two other i2c dummy for gpadc and power purpose. 88pm805.c handles specifically for 805, such as chip init, irq init/handle, mfd device register, including codec, headset/mic detect etc. the i2c operation of both 800 and 805 are via regmap, and 88pm80x-i2c exported a group of r/w bulk r/w and bits set API for facility.
