2013-06-18mfd: 88pm80x: Change chip id definition and detectionChao Xie1-7/+40
Change the chip id definition and detection and then: 1. We no longer need to add PM800_CHIP_XXX for the coming revision. 2. We no longer need to pass driver_data in i2c_device_id as we can distinguish the chips from the CHIP_ID register.

2012-07-16mfd: Remove __devexit annotation for pm80x_deinitAxel Lin1-1/+1
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.

2012-07-09mfd: Add companion chip in 88pm80xQiao Zhou1-0/+28
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.

2012-07-09mfd: Support 88pm80x in 80x driverQiao Zhou1-0/+116
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.
