d22409e2dc i2c: designware_i2c: Drop scl_sda_cfg parameter
Instead of passing this parameter into __dw_i2c_set_bus_speed(), pass in
the driver's private data, from which the function can obtain that
information. This allows the function to have access to the full state of
the driver.

dd3c1602cf i2c: designware_i2c: Use an accurate bus clock instead of MHz
At present the driver uses an approximation for the bus clock, e.g. 166MHz
instead of 166 2/3 MHz.

This can result in small errors in the resulting I2C speed, perhaps 0.5%
or so.

Adjust the existing code to start from the accurate figure, even if later
rounding reduces this accuracy.

Update the bus speed code to work in KHz instead of MHz, which removes
most of the error.

7c841d844f sunxi: Automate loading from 128KB MMC offset
Since commit 067e0b9684 ("sunxi: Allow booting from 128KB SD/eMMC offset")
we support having the SPL loaded from either the traditional 8KB SD
card/eMMC offset, or from the alternative location at 128KB. However the
sector to find the U-Boot image was still hard-coded at compile time,
and had to be adjusted for one of the two choices.

Since we can actually override the function to return the sector offset,
we can just check the boot source byte there to select the proper offset
based on from where the SPL was loaded.

This allows the very same binary image to be loaded from either 128KB or
8KB, with the U-Boot proper image always being located just behind the SPL.

832685f07c clk: mediatek: use unsigned type for returning the clk rate
mtk_clk_find_parent_rate is calling clk_get_rate to know the rate
of a parent clock. clk_get_rate returns a ulong, while
mtk_clk_find_parent_rate returns an int. This implicit cast creates
an issue for clock rates big enough to need the full 32 bits to
store its data. When that happen the clk rate will become incorrect
because of the implicit cast between ulong -> int -> ulong.

This commit change the return type of mtk_clk_find_parent_rate to
ulong.

533f2433ff sunxi: Add Libre Computer ALL-H5-CC H5 board
The Libre Computer ALL-H5-CC board is an upgraded version of the
ALL-H3-CC. Changes include:

  - Gigabit Ethernet via external RTL8211E Ethernet PHY
  - 16 MiB SPI NOR flash memory
  - PoE tap header
  - Line out jack removed

Only H5 variant test samples were made available, and the vendor is not
certain whether other SoC variants would be made or not. Furthermore the
board is a minor upgrade compared to the ALL-H3-CC. Thus the device tree
simply includes the one for the ALL-H3-CC, and adds the changes on top.

The device tree was synced over from the Linux kernel, along with other
H3/H5 changes, in a previous patch. Thus only the defconfig and an entry
to the MAINTAINERS file is added.

986b5e8c4a sunxi: Add Libre Computer ALL-H3-IT H5 board
The Libre Computer ALL-H3-IT board is a small single board computer that
is roughly the same size as the Raspberry Pi Zero, or around 20% smaller
than a credit card.

The board features:

  - H2, H3, or H5 SoC from Allwinner
  - 2 DDR3 DRAM chips
  - Realtek RTL8821CU based WiFi module
  - 128 Mbit SPI-NOR flash
  - micro-SD card slot
  - micro HDMI video output
  - FPC connector for camera sensor module
  - generic Raspberri-Pi style 40 pin GPIO header
  - additional pin headers for extra USB host ports, ananlog audio and
    IR receiver

Only H5 variant test samples were made available, but the vendor does
have plans to include at least an H3 variant. Thus the device tree is
split much like the ALL-H3-CC, with a common dtsi file for the board
design, and separate dts files including the common board file and the
SoC dtsi file. The other variants will be added as they are made
available.

The device tree was synced over from the Linux kernel, along with other
H3/H5 changes, in a previous patch. Thus only the defconfig and an entry
to the MAINTAINERS file is added.
