84ff8f622d regmap: Add raw read/write functions
The regmap functions currently assume that all register map accesses
have a data width of 32 bits, but there are maps that have different
widths.

To rectify this, implement the regmap_raw_read and regmap_raw_write
functions from the Linux kernel API that specify the width of a desired
read or write operation on a regmap.

Implement the regmap_read and regmap_write functions using these raw
functions in a backwards-compatible manner.

7f0e366999 regmap: Introduce init_range
Both fdtdec_get_addr_size_fixed and of_address_to_resource can fail with
an error, which is not currently checked during regmap initialization.

Since the indentation depth is already quite deep, extract a new
'init_range' method to do the initialization.

8e39afcd94 dm: core: Mirror the chosen node parse logic in the livetree scanning
Commit f2006808f0: ("dm: core: parse chosen node") added a logic
to parse the chosen node during dm_scan_fdt_node(), but unfortunately
it missed adding the same logic in dm_scan_fdt_live(). This mirrors
the logic in the livetree version.

The weird thing is that commit f2006808f0 did update the test case
to test such logic, but even if I reset to that commit, the test case
still fails, and I have no idea how it could pass.

With this fix, the following 2 test cases now pass:

Test: dm_test_bus_children: bus.c
test/dm/bus.c:112, dm_test_bus_children(): num_devices ==
list_count_items(&uc->dev_head): Expected 7, got 6

Test: dm_test_fdt: test-fdt.c
test/dm/test-fdt.c:184, dm_test_fdt(): num_devices ==
list_count_items(&uc->dev_head): Expected 7, got 6

8d773c4ab3 dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()
Currently the comments of several APIs (eg: dm_init_and_scan()) say:

@pre_reloc_only: If true, bind only drivers with the DM_FLAG_PRE_RELOC
flag. If false bind all drivers.

The 'Pre-Relocation Support' chapter in doc/driver-model/README.txt
documents the same that both device tree properties and driver flag
are supported.

However the implementation only checks these special device tree
properties without checking the driver flag at all. This updates
lists_bind_fdt() to consider both scenarios.

1f758b7936 mtd: Drop duplicate MTD_PARTITIONS Kconfig option
Commit 9c5b00973b ("Convert CONFIG_MTD_PARTITIONS et al to Kconfig")
introduced a publicly visible Kconfig entry for the
CONFIG_MTD_PARTITIONS option, while the rework on MTD partitioning
was in progress, and we somehow did not notice that the same Kconfig
entry was added by commit 4048a5c519 ("mtd: declare MTD_PARTITIONS
symbol in Kconfig"), but this time as an invisible entry (this can
only be selected by other options).

Keep the non-visible version of this symbol, since MTD_PARTITIONS is
not something the user should be able to enable/disable directly.

is currently ignoring CRC check failure on command resposes which
have CRC atteched to it, which can be potentially dangerous. Even
more grueling problem happens when the command response is followed

05bbd676a7 net: phy: mscc: add support for VSC8574 PHY
The VSC8574 PHY is a 4-port PHY that is 10/100/1000BASE-T, 100BASE-FX,
1000BASE-X and triple-speed copper SFP capable, can communicate with
the MAC via SGMII, QSGMII or 1000BASE-X, supports WOL, downshifting and
can set the blinking pattern of each of its 4 LEDs, supports SyncE as
well as HP Auto-MDIX detection.

This adds support for 10/100/1000BASE-T and SGMII/QSGMII link with the
MAC.

The VSC8574 has also an internal Intel 8051 microcontroller whose
firmware needs to be patched when the PHY is reset. If the 8051's
firmware has the expected CRC, its patching can be skipped. The
microcontroller can be accessed from any port of the PHY, though the CRC
function can only be done through the PHY that is the base PHY of the
package (internal address 0) due to a limitation of the firmware.

The GPIO register bank is a set of registers that are common to all PHYs
in the package. So any modification in any register of this bank affects
all PHYs of the package.

The revA of the VSC8584 PHY (which is not and will not be publicly

1e5d8aaf4f aspeed: ast2500: fix D2-PLL clock setting in RGMII mode
The algorithm in the ast2500_calc_clock_config() routine suffers from
integer rounding and the requested rate does not get the appropriate
set of Numerator, Denumerator, Post Divider parameters.

This is the case for the D2-PLL clock used by the MAC controllers in
RGMII mode. The requested rated is 250MHz but a 251MHz is assigned.

The easiest way to fix this problem is to introduce an array of clock
settings defining the N, M, P parameters for well known frequencies
used by the Aspeed SoC.

When the bus switches to 1.8V mode of operation, it is necessary to
verify that the card correctly initiated and completed the voltage
switch. This is done by reading out the state of DATA0 line.

This patch implement support for reading out the state of the DATA0
line, so the MMC core code can correctly switch to 1.8V mode.

Add check to avoid touching the SCC tuning registers in case the IP
doesn't support them or if the support isn't in place yet.

c83da2ebc0 mmc: tmio: Preinitialize regulator to 3.3V
Preinitialize the SD card signals regulator to 3.3V, which is the
default post-reset setting, to be sure the regulator is set to a
valid value.

8171f99e7d mmc: tmio: Configure clock before any other IOS
Configure the clock settings before reconfiguring any other IO settings.
This is required when the clock must be stopped before changing eg. the
pin configuration or any of the other properties of the bus. Running the
clock configuration first allows the MMC core to do just that.
