If an error occurs allocating memory for zram we will not be able to
fullfill the request to store the page in zram. The swap subsystem still
continues to try to swap out pages to zram even when this error occurs
since there is currently no facility to stop the swap subsystem from
swapping out during such errors. This can cause the system to be
overflowed with logging errors.
Reduce the amount of logging to prevent the kernel log from being filled
with these error messages

During irq_disable, mdp_lock is held and intr status is checked and
cleared if any. If a new irq is triggered from another CPU at the
same point, it would ideally be waiting on mdp_lock held by the other
CPU. And when the mdp_lock is released after clearing the irq, mdp_isr
is executed and at this point, clks might have been disabled. To avoid
it, protect the clk_ena variable with mdp_lock and also check for the
clk_ena status and skip irq handling when it is disabled.

On few recent targets APSS L2 memory is moved to APC domain which were
earlier on Mx domain. This can cause inrush current while bringing up
huge memories like modem and adsp.
To mitigate inrush current, bring up comparatively lesser memory in
size(for eg MDP memory) before bringing up huge memories like modem or
adsp. This way MDP memory introduce an intermediate load on MX rail.
During boot, gdsc driver will set MEM and PERIPHERAL bits. This driver
makes sure that dependent subsystems are powered up. Once done, call
gdsc_allow_clear_retention() API to allow retention of MDP memories.

On smart panels, Early Clock Gating (ECG), is initiated when current
frame transfer is finished and no new frame update is queued. To track
these two different states, driver maintains the state machine
for HW transfer and SW's new frame update. Currently SW state machine is
cleared only after HW transfer has started. Now in normal scenarios SW
state should be cleared before HW is finished and if there is no new
frame update queued then ECG will be initiated. However due to CPU
scheduling, thread that needs to clear SW state got preempted. In the
meantime HW finished the transfer and updated its state machine in the
interrupt context. Since at this moment SW state wasn't cleared, ECG
was not initiated. Avoid this situation by clearing SW state before HW
transfer is started.
