89f6602d4b - Do not enable AMD memory encryption in Kconfig by default due to
shortcomings of some platforms, leading to boot failures.
 
 - Mask out invalid bits in the MXCSR for 32-bit kernels again because
 Thomas and I don't know how to mask out bits properly. Third time's the
 charm.

f24dbaaab4 pinctrl: qcom: spmi-mpp: hardcode IRQ counts
The probing of this driver calls platform_irq_count, which will

preparation for converting this driver to be a hierarchical IRQ
chip, hardcode the IRQ count based on the hardware type so that all
the IRQs are not configured immediately and are configured on an

This change will also allow for the removal of the interrupts property
later in this patch series once the hierarchical IRQ chip support is in.

This patch also removes the generic qcom,spmi-mpp OF match since we

The read and writes from the fifo are from a buffer, with various

Therefore, fix this by using iowrite32()/ioread32() instead of
ioread32_rep()/iowrite32_rep().

Also, the write into FIFO must be performed with an offset from the
message ram base address. Therefore, fix the base address to
mram_base.
