[PATCH 0/2] arm64: dts: st: fix sai3b unit address on stm32mp2

[Mateusz Nowicki]

The sai3b node on stm32mp251 and stm32mp231 has a unit address taken
from the secure alias of SAI3, while its reg property and all other SAI
nodes use the non-secure alias. The reg property is correct, so there
is no functional change.

The typo comes from two different commits, so each SoC gets its own
patch with its own Fixes tag.

[PATCH 1/2] arm64: dts: st: fix sai3b unit address on stm32mp251

[Mateusz Nowicki]

The unit address of the sai3b node, 502b0024, is the address of the
SAI_BCR1 register in the secure alias of SAI3. The reg property of the
node translates to the non-secure address 0x402b0024, which all other
SAI nodes use. Fix the unit address to match.

The unit address of the sai3b node, 502b0024, is the address of the
SAI_BCR1 register in the secure alias of SAI3. The reg property of the
node translates to the non-secure address 0x402b0024, which all other
SAI nodes use. Fix the unit address to match.

Applied on stm32-next.
