* mfd: twl4030-madc: Remove __exit_p annotationArnd Bergmann2013-03-151-1/+1
| | | | | | | | | | | | | | | 4740f73fe5 "mfd: remove use of __devexit" removed the __devexit annotation on the twl4030_madc_remove function, but left an __exit_p() present on the pointer to this function. Using __exit_p was as wrong with the devexit in place as it is now, but now we get a gcc warning about an unused function. In order for the twl4030_madc_remove to work correctly in built-in code, we have to remove the __exit_p.

On a TunnelCreek system I am working on, this resulted in the SMBIOS and GPIO devices being removed when it couldn't read the base address for the watchdog timer. This patch accommodates partial population of the lpc_sch_cells array and only aborts if all the base address registers are disabled. A max size array is allocated and the individual device cells are added to it after their base addresses are successfully determined. This simplifies the code a bit by removing the need for the separate tunnelcreek cells array and combining some of the add/remove logic.

In order for us to do that, the trigger needs to be set in the associated flags. However, unless a irq_set_type() function pointer is passed when registering the IRQ chip, the IRQ subsystem will refuse to do it. For that reason, we're providing one.

However the bit mask for hwirqs 43 and 44 was shifting the bit mask incorrectly, resulting in the wrong IRQ being mased/unmasked. Further while the patch would mask/unmask the correct line, when the interrupt actually came in, it would still be treated as a valid hwirq. The offsetting applied when masking/unmasking was not applied when handling the IRQ, i.e. the falling edge lines were not routed back to the rising edge lines. This fixes both cases. The end result has been tested with the SIM detect IRQ, GPIO12, hwirq 46 and 62.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In an upcoming patch, the gpio-ab8500 driver will relinquish all IRQ handling capability and pass it back into the AB8500 core driver. This will aid in reducing massive code duplication within the kernel. Also, most of the functionality is already in the AB8500 core driver, as the GPIO IRQs are actually sandwiched between lots of other IRQs which the core driver already handles. All we're doing here is providing the core driver with knowledge that each GPIO has two IRQs assigned to it; one for rising and a separate one for falling.

| * | mfd: rtsx: Fix issue that booting OS with SD card insertedWei WANG2013-02-141-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Realtek card reader supports both SD and MS card. According to the settings of rtsx MFD driver, SD host will be probed before MS host. If we boot/reboot Linux with SD card inserted, the resetting flow of SD card will succeed, and the following resetting flow of MS is sure to fail. Then MS upper-level driver will ask rtsx driver to turn power off. This request leads to the result that the following SD commands fail and SD card can't be accessed again. In this commit, Realtek's SD and MS host driver will check whether the card that upper driver requesting is the one existing in the slot. If not, Realtek's host driver will refuse the operation to make sure the exlusive accessing at the same time.
