[ Upstream commit 4ac4c1d794e7ff454d191bbdab7585ed8dbf3758 ]

Although the Samsung SoC keypad binding defined
linux,keypad-no-autorepeat property, Linux driver never implemented it
and always used linux,input-no-autorepeat.  Correct the DTS to use
property actually implemented.

This also fixes dtbs_check errors like:

[ Upstream commit 53cc9baeb9bc2a187eb9c9790d30995148852b12 ]

clang-16 warns about casting between incompatible function types:

arch/arm/crypto/sha256_glue.c:37:5: error: cast from 'void (*)(u32 *, const void *, unsigned int)' (aka 'void (*)(unsigned int *, const void *, unsigned int)') to 'sha256_block_fn *' (aka 'void (*)(struct sha256_state *, const unsigned char *, int)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]

      |                                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

      |                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Fix the prototypes for the assembler functions to match the typedef.
The code already relies on the digest being the first part of the
state structure, so there is no change in behavior.

[ Upstream commit 53cc9baeb9bc2a187eb9c9790d30995148852b12 ]

clang-16 warns about casting between incompatible function types:

arch/arm/crypto/sha256_glue.c:37:5: error: cast from 'void (*)(u32 *, const void *, unsigned int)' (aka 'void (*)(unsigned int *, const void *, unsigned int)') to 'sha256_block_fn *' (aka 'void (*)(struct sha256_state *, const unsigned char *, int)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]
   37 |                                 (sha256_block_fn *)sha256_block_data_order);
      |                                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
arch/arm/crypto/sha512-glue.c:34:3: error: cast from 'void (*)(u64 *, const u8 *, int)' (aka 'void (*)(unsigned long long *, const unsigned char *, int)') to 'sha512_block_fn *' (aka 'void (*)(struct sha512_state *, const unsigned char *, int)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]

      |                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Fix the prototypes for the assembler functions to match the typedef.
The code already relies on the digest being the first part of the
state structure, so there is no change in behavior.

[ Upstream commit 79978bff2e4b8e05ebdf5fc3ee6b794002393484 ]

We identified that the PHYs actually do not work since commit 7da7b84fee58
("ARM: dts: imx6dl-yapp4: Move phy reset into switch node") as
a coincidence of several circumstances.

The reset signal is kept asserted by a pull-down resistor on the board
unless it is deasserted by GPIO from the SoC. This is to keep the switch
dead until it is configured properly by the kernel and user space.

Prior to the referenced commit the switch was reset by the FEC driver
and the reset GPIO was actively deasserted. The mdio-bus was scanned
and the attached switch and its PHYs were found and configured.

With the referenced commit the switch is reset by the qca8k driver.
Because of another bug in the qca8k driver, functionality of the reset
pin depends on its pre-kernel configuration. See commit c44fc98f0a8f
("net: dsa: qca8k: fix illegal usage of GPIO")

The problem did not appear until we removed support for the switch
and configuration of its reset pin from the bootloader.

To fix that, properly describe the internal mdio-bus configuration of
the qca8334 switch. The PHYs are internal to the switch and sit on its
internal mdio-bus.
