The Microchip KSZ9477/KSZ9897/KSZ9567 7-Port Gigabit Ethernet Switches
support SGMII/RGMII/MII/RMII with register access via SPI, I2C, or MDIO.
This driver currently supports I2C register access but SPI or MDIO register
access can be easily added at a later time.
Tagging is not implemented and instead the active port is tracked to
avoid needing a tag to store port information.
This was tested with the imx8mm-venice-gw7901 board which has a
KSZ9897S switch with an IMX8MM FEC MAC master connected via RGMII_ID.

When using uclass_get_device* to get the FEC device we need to use
device sequence instead of index into UCLASS_ETH. In systems where for
example a I2C based DSA switch exists it will probe before the FEC
master and its ports will be registered first and have the first
indexes yet the FEC's sequence comes from the device-tree alias.
Take for example the imx8mm-venice-gw7901 board which has an i2c based
DSA switch:
u-boot=> net list
eth1 : lan1 00:0d:8d:aa:00:2f
eth2 : lan2 00:0d:8d:aa:00:30
eth3 : lan3 00:0d:8d:aa:00:31
eth4 : lan4 00:0d:8d:aa:00:32
eth0 : ethernet@30be0000 00:0d:8d:aa:00:2e active
Thus in this case uclass_get_device(UCLASS_ETH, 0, &dev) returns lan1
which is wrong but uclass_get_device_seq(UCLASS_ETH, 0, &dev) returns
ethernet@30be000 which is correct.

If reset-gpio is defined by device-tree use that if
CONFIG_PCIE_IMX_PERST_GPIO is not defined.
Note that after this the following boards which define
CONFIG_PCIE_IMX_PERST_GPIO in their board header file as well as their
device-tree should be able to remove CONFIG_PCIE_IMX_PERST_GPIO without
consequence:
- mx6sabresd
- mx6sxsabresd
- novena
- tbs2910
- vining_2000
Note that the ge_bx50v3 board uses CONFIG_PCIE_IMX_PERST_GPIO and does
not have reset-gpios defined it it's pcie node in the dt thus removing
CONFIG_PCIE_IMX_PERST_GPIO globally can't be done until that board adds
reset-gpios.

Unfortunately the UART driver in current Linux for Armada 3700 expects
UART's parent clock to be XTAL and calculats baudrate divisor according
to XTAL clock. Therefore we must switch back to XTAL clock before
booting kernel.
Implement .remove method for this driver with DM_FLAG_OS_PREPARE flag
set.
If current baudrate is unsuitable for XTAL clock then we do not change
anything. This can only happen if the user either configured unsupported
settings or knows what they are doing and has kernel patches which allow
usage of non-XTAL parent clock.

Using TBG clock as parent clock for UART allows us using higher
baudrates than 230400.
Turris MOX with external FT232RL USB-UART works fine up to 3 MBaud
(which is maximum for this USB-UART controller), while EspressoBIN with
integrated pl2303 USB-UART also works fine up to 6 MBaud.
Slower baudrates with TBG as a parent clock can be achieved by
increasing TBG dividers and oversampling divider. When using the slowest
TBG clock, minimal working baudrate is 300.

UART parent clock is by default the platform's xtal clock, which is
25 MHz.
The value defined in the driver, though, is 25.8048 MHz. This is a hack
for the suboptimal divisor calculation
Divisor = UART clock / (16 * baudrate)
which does not use rounding division, resulting in a suboptimal value
for divisor if the correct parent clock rate was used.
Change the code for divisor calculation to round to closest value, i.e.
Divisor = Round(UART clock / (16 * baudrate))
and change the parent clock rate value to that returned by
get_ref_clk().
This makes A3720 UART stable at standard UART baudrates between 1800 and
230400.

At the moment, the U-Boot serial_msm driver does not initialize the
UART_DM_DMEN register with the required value. Usually this does not
cause any problems, because there is Qualcomm's LK bootloader running
before U-Boot which initializes the register with the correct value.
It's important that this register is initialized correctly, because
the U-Boot driver does not make use of the BAM/DMA or single character
mode functionality of the UART controller. A different bootloader
before U-Boot might initialize the register differently.
For example, on DragonBoard 410c U-Boot can also be installed to the
"aboot" partition (replacing LK entirely). In this case U-Boot is
loaded directly by SBL, which seems to use the single-character mode
for some reason. In single character mode there is always just one
char in the FIFO, instead of the 4 characters expected by
msm_serial_fetch(). It also causes issues with "earlycon" later in
the Linux kernel, which tries to output 4 chars at once,
but only the first char will be written.
This causes early UART log in Linux to be corrupted like this:
[ 00ano:ameoi .Q1B[ 00ac _idaM00080oo'ahani-lcle._20). 15NdNii 5 SPMSJ20:U2
[ 00rkoolmsamel
[ 00Fw ]elamletopsioble
[ 00ore
instead of
[ 0.000000] Booting Linux on physical CPU 0x0000000000 [0x410fd030]
[ 0.000000] Machine model: Qualcomm Technologies, Inc. APQ 8016 SBC

[ 0.000000] printk: bootconsole [msm_serial_dm0] enabled
Make sure to initialize UART_DM_DMEN correctly to fix this issue
when loading U-Boot directly after SBL (instead of through LK).
There is no functional difference when loading U-Boot through LK
since LK also initializes UART_DM_DMEN to 0x0. [1]

This patch adds a limited pulse-width modulator to sandbox's Chromium OS
Embedded Controller emulation. The emulated PWM device supports multiple
channels but can only set a duty cycle for each, as the actual EC
doesn't expose any functionality or information other than that. Though
the EC supports specifying the PWM channel by its type (e.g. display
backlight, keyboard backlight), this is not implemented in the emulation
as nothing in U-Boot uses this type specification.
This emulated PWM device is then used to test the Chromium OS PWM driver
in sandbox. Adding the required device node to the sandbox test
device-tree unfortunately makes it the first PWM device, so this also
touches some other tests to make sure they still use the sandbox PWM.

Each _device_ belonging to a given uclass of course has its own ->ops,
of a type determined by and known to the uclass.
However, no instance of a uclass_driver seems to populate ->ops, and
the only reference to it in code is this relocation.
Moreover, it's not really clear what could sensibly be assigned; it
would have to be some "struct uclass_ops *" providing a set of methods
for the core to call on that particular uclass, but should the need
for that ever arise, it would be better to have a member of that
particular type instead of void*.
