[PATCH AUTOSEL 5.9 01/55] ASoC: mediatek: mt8183-da7219: fix DAPM paths for rt1015

[Sasha Levin]

From: Tzung-Bi Shih <tzungbi@google.com>

[ Upstream commit eb5a558705c7f63d06b4ddd072898b1ca894e053 ]

RT1015's output widget name is "SPO" instead of "Speaker".  Fixes it to
use the correct names.

[PATCH AUTOSEL 5.9 41/55] i2c: mediatek: move dma reset before i2c reset

[Sasha Levin]

From: Qii Wang <qii.wang@mediatek.com>

[ Upstream commit aafced673c06b7c77040c1df42e2e965be5d0376 ]

The i2c driver default do dma reset after i2c reset, but sometimes
i2c reset will trigger dma tx2rx, then apdma write data to dram
which has been i2c_put_dma_safe_msg_buf(kfree). Move dma reset
before i2c reset in mtk_i2c_init_hw to fix it.

[PATCH AUTOSEL 5.9 47/55] arm64: kexec_file: try more regions if loading segments fails

[Sasha Levin]

From: Benjamin Gwin <bgwin@google.com>

[ Upstream commit 108aa503657ee2fe8aa071dc620d96372c252ecd ]

It's possible that the first region picked for the new kernel will make
it impossible to fit the other segments in the required 32GB window,
especially if we have a very large initrd.

Instead of giving up, we can keep testing other regions for the kernel
until we find one that works.
