It is more idiomatic to process things relating to the regulator in its driver. This patch moves both processing of device tree relating to the regulator and checking if the regulator is external from arizona-core into the regulator driver.

On the wm5102 the register patches are applied manually, rather than by the regmap core. This application is wrapped in calls to regcache_cache_bypass. However, this is dangerous as other threads may be accessing the hardware at the same time as the pm_runtime operations and if they do so during the period whilst cache_bypass is enabled those writes will miss the cache when they shouldn't. Apply the register patch using the new regmap_multi_reg_write_bypassed function to avoid this problem. Also remove the call to regcache_cache_bypass from the hardware patch application as it is unneeded there and creates a similar window for writes to miss the cache.

As of commit 03e361b2 ("mfd: Stop setting refcounting pointers in original mfd_cell arrays"), the "cell" parameter of mfd_add_devices() is "const" again. Hence make all cell data passed to mfd_add_devices() const where possible. Signed-off-by: NGeert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: NLee Jones <lee.jones@linaro.org>

When setting GPIO defaults we are required to make a distinction between writing 0x0000 to the registers and leaving them untouched. When we receive between 0x0000 and 0xFFFF (inclusive) from either Platform Data or Device Tree, we should write the provided configuration to the device. 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.

Runtime power management does not function during system suspend but the Arizona devices need to use runtime power management to power up the device in order to handle interrupts. Try to avoid interrupts firing during resume by disabling the primary IRQ before interrupts are reenabled on resume and only reenabling it again during main resume. The goal is to avoid issues in the situation where an interrupt is asserted during resume (eg, due to it being the wake source) and the interrupt handling gets scheduled prior to the device being able to handle runtime PM.

Make sure that we don't race with the initial device boot by only doing the initialisation after we've waited for the boot to complete. The runtime PM code already waits for the boot to complete before it syncs the register patches so in most systems if a race does occur we will power down very soon afterwards and recover anyway.
