Clients may need irq number to handle doorbell, e.g. to use a common irq
handler framework.

When the buffer pointed to by test_virt_addr is allocated, there
is no synchronization with respect to checking if it is necessary
to allocate the buffer. This can lead to various adversarial
scenarios, where multiple concurrent allocations of the same
buffer can occur, resulting in memory leaks.
To avoid these scenarios, make the check and allocation of the
buffer atomic with respect to other accesses to test_virt_addr.

qti_flash_led_prepare() API is used by flash clients (E.g. Camera) to
query maximum current available for flash. Add support for this API
which initially returns maximum current that is supported for flash
LED module (2000 mA). Also, add a sysfs parameter under switch devices
to show max available flash current.

This reverts commit fe2731211e.
By default the commit muxes the pin to a GPIO upon a request_irq()
call from the client driver. This is incorrect as the client driver
could have muxed the pin already for a different purpose. Hence,
revert this default behavior to not enforce this on the clients.

Add the initial support required to share memory buffers
between VMs. This driver exposes an interface to userspace
clients to request memory to be allocated from another VM,
and added to the current VM. The VMs communicate with each
other via the use of the hypervisor message queues, as well
as utilize various facilities offered by the Haven resource
manager to manage memory that is transferred from one VM
to another.

Add a check to mark only cached buffers as iocoherent.
We can't enable io-coherency for uncached buffers because
of situations where hardware might snoop the cpu caches
which can have stale data.This happens primarily due to the
limitations of dma caching APIs available on arm64.

When set_rate is called on unprepared clocks new vdd_level
requirement is not cached, which leads to incorrect votes
when later clk_prepare is called. Clocks may not be prepared
when clk pre change rate is called for set_rate change request,
thus cache vdd level and only apply vote during clk prepare.
