03de305ec4 Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"
As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

d678a59d2d Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d, reversing
changes made to 2ee6f3a5f7.

clk/qcom: use offsets for RCG registers
The RCG registers always have the same offsets, so only store the base
CMD register address and calculate the others relative to that.

dts: dragonboard820c: use correct bindings for clocks
Don't use hardcoded clock IDs, use the IDs from the dt-bindings to be
compatible with upstream.

clk/qcom: fix rcg divider value
The RCG divider field takes a value of (2*h - 1) where h is the divisor.
This allows fractional dividers to be supported by calculating them at
compile time using a macro.

However, the clk_rcg_set_rate_mnd() function was also performing the
calculation. Clean this all up and consistently use the F() macro to
calculate these at compile time and properly support fractional divisors.

Additionally, improve clk_bcr_update() to timeout with a warning rather
than hanging the board, and make the freq_tbl struct and helpers common
so that they can be reused by future platforms.

clk/qcom: use function pointers for enable and set_rate
Currently, it isn't possible to build clock drivers for more than one
platform due to how the msm_enable() and msm_set_rate() callbacks are
implemented.

Extend qcom_clk_data to include function pointers for these and convert
all platforms to use them.

Previously, clock drivers relied on include/configs/<board.h> to include the
board specific sysmap header, however as most of the header contents are clock
driver related, import the contents directly into each clock driver and
remove the header. The only exception here is the dragonboard820c board file
which includes some pinctrl macros, those are also inlined.

clk/qcom: handle resets and clocks in one device
Qualcomm's clock controller blocks actually do much more than it
says on the tin.. They provide clocks, resets and power domains.
Currently, U-Boot requires one to spawn 2 separate devices for
controlling clocks and resets, both spanning the same register space.
Refactor the code to make it work with just a single DT node, making
it compatible with upstream Linux bindings and dropping the dedicated
reset driver in favour of including it in the clock driver.

Heavily inspired by Renesas code for a similar hw block.

[caleb: moved drivers to clk/qcom, added reset driver and adjusted bind
logic. Imported qcom,gcc-ipq4019.h from Linux]

clk/qcom: move from mach-snapdragon
Clock drivers don't belong here, move them to the right place and
declutter mach-snapdragon a bit.

To de-couple these drivers from specific "target" platforms, add
additional config options to enable each clock driver gated behind a
common CLK_QCOM option and enable them by default for the respective
targets. This will make future work easier as we move towards a generic
Qualcomm target.
