2013-12-12mfd/rtc: s5m: fix register updating by adding regmap for RTCKrzysztof Kozlowski2-11/+25
Rename old regmap field of "struct sec_pmic_dev" to "regmap_pmic" and add new regmap for RTC. On S5M8767A registers were not properly updated and read due to usage of the same regmap as the PMIC. This could be observed in various hangs, e.g. in infinite loop during waiting for UDR field change. On this chip family the RTC has different I2C address than PMIC so additional regmap is needed.

2013-11-11mfd: Fix memory leak in mfd_add_devices()Geert Uytterhoeven1-4/+8
If the first call to mfd_add_device() fails, no child devices have been registered to the parent yet, and thus mfd_remove_devices() won't find anything to remove nor free. Hence the previously allocated array of atomic_t objects will leak. Free the array instead of calling mfd_remove_devices() on failure during the first loop iteration to fix this.

2013-11-11mfd: Stop setting refcounting pointers in original mfd_cell arraysGeert Uytterhoeven1-8/+9
Commit 1e29af62f2b285bd18685da93c3ce8c33ca2d1db ("mfd: Add refcounting support to mfd_cells") had to drop the "const" keyword on the "cell" parameter of mfd_add_devices(), as it added the refcounting pointers to the objects of the passed mfd_cell array itself. However, the mfd core code operates on copies of the mfd_cell objects, so there's no need to modify the originally passed objects. Hence, move the setting of the refcounting pointers from mfd_add_devices() to mfd_platform_add_cell(), where the copy of the mfd_cell objects is made. mfd_clone_cell() can just pass (a copy of) the original usage_count pointer. This allows to make the "cell" parameter of mfd_add_devices() "const" again, and avoids future race conditions when registering multiple instances of the same device in parallel.

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.

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.
