08e64cece2 net: phy: marvell: Do not reset 88e1310 after autoneg
Commit a058052c "net: phy: do not read configuration register on reset",
changes the behaviour of the phy_reset function such that the state of
the BMCR register is not preserved during reset.

Change the config function for the m88e1310 so that it does not do a
reset after configuring auto-negotiation.

79887749f8 net: phy: micrel: add support for KSZ886x switches in MIIM mode
This patch adds a phy driver for the Micrel KSZ886x switches.

Similarly to the KSZ8895, SoC MAC is directly connected to the switch
MAC on the switch CPU port, so the link to the switch is always up.

KSZ886x switches can be used in the following configuration modes:
- Unmanaged mode with config stored in external EEPROM
- Managed mode over SPI
- Managed mode over I2C
- Managed mode over mdio/mdc (aka MIIM or SMI)

This patch supports only unmanaged and MIIM modes.

Based on Micrel KSZ886x driver from Linux kernel and
Micrel KSZ8895 driver from U-Boot.

Verified with the KSZ8863MLL.

dad7b74045 net: rtl8169: fix switching between adapters
The rtl8169 driver uses a global variable to store the register address
of the adapter being operated upon. This is updated to point at the
correct adapter when sending or receiving a packet, or shutting down the
adapter, but not when initializing the adapter. Consequently, switching
between different adapters within the same U-Boot runtime does not work
correctly since the driver programs the wrong registers during
rtl8169_eth_start() -> rtl8169_common_start() -> rtl8169_hw_start().

Note that since rtl8169_eth_stop() does set the global variable, the
second consecutive attempt to use the "new" adapter did work even before
this patch, because each time network usage is shut down, the network
core calls stop, which sets the variable so that the next start does
actually initialize the hardware, and the adapter works.

Equally, rtl8169_eth_probe() calls rtl_init() which sets the global, so
if using only a single device, or if picking the "right" device (based on
probe order) when multiple devices are present, ioaddr will already be set
correctly from the get-go, so the issue does not occur.

7748b41482 spl: nand: sunxi: add support for NAND config auto-detection
NAND chips are supposed to expose their capabilities through advanced
mechanisms like READID, ONFI or JEDEC parameter tables. While those
methods are appropriate for the bootloader itself, it's way to
complicated and takes too much space to fit in the SPL.

Replace those mechanisms by a dumb 'trial and error' mechanism.

With this new approach we can get rid of the fixed config list that was
used in the sunxi NAND SPL driver.

4e7d1b3beb spl: nand: sunxi: split 'load page' and 'read page' logic
Split the 'load page' and 'read page' logic in 2 different functions so
we can later load the page and test different ECC configs without the
penalty of reloading the same page in the NAND cache.

We also move common setup to a dedicated function (nand_apply_config()) to
avoid rewriting the same values in NFC registers each time we read a page.

These new functions are passed a pointer to an nfc_config struct to limit
the number of parameters.

bb9783b66b spl: nand: sunxi: rework status polling loop
check_value_xxx() helpers are using a 1ms delay between each test, which
can be quite long for some operations (like a page read on an SLC NAND).
Since we don't have anything to do but to poll this register, reduce the
delay between each test to 1us.

While we're at it, rename the max_number_of_retries parameters and the
MAX_RETRIES macro into timeout_us and DEFAULT_TIMEOUT_US to reflect that
we're actually waiting a given amount of time and not only a number of
retries.

80ef700f8d spl: nand: support redundant u-boot image
On modern NAND it's more than recommended to have a backup copy of the
u-boot binary to recover from corruption: bitflips are quite common on
MLC NANDs, and the read-disturbance will corrupt your u-boot partitition
more quickly than what you would see on an SLC NAND.

Add an extra Kconfig option to specify the offset of the redundant u-boot
image.

c4adf9db5d spl: nand: sunxi: remove support for so-called 'syndrome' mode
The sunxi SPL NAND controller driver supports use 'BootROM'-like configs,
that is, configs where the ECC bytes and real data are interleaved in the
page instead of putting ECC bytes in the OOB area.

Doing that has several drawbacks:
- since you're interleaving data and ECC bytes you can't use the whole page
  otherwise you might override the bad block marker with non-FF bytes.
- to solve the bad block marker problem, the ROM code supports partially
  using the page, but this introduces a huge penalty both in term of read
  speed and NAND memory usage. While this is fine for rather small
  binaries(like the SPL one which is at maximum 24KB large), it becomes
  non-negligible for the bootloader image (several hundred of KB).
- auto-detection of the page size is not reliable (this is in my opinion
  the biggest problem). If you get the page size wrong, you'll end up
  reading data at a different offset than what was specified by the caller
  and the reading may succeed (if valid data were written at this address).

For all those reasons I think it's wiser to completely remove support for
'syndrome' configs. If we ever need to support it again, then I'd recommend
specifying all the config parameters through Kconfig options.

135aa95002 clk: convert API to match reset/mailbox style
The following changes are made to the clock API:
* The concept of "clocks" and "peripheral clocks" are unified; each clock
  provider now implements a single set of clocks. This provides a simpler
  conceptual interface to clients, and better aligns with device tree
  clock bindings.
* Clocks are now identified with a single "struct clk", rather than
  requiring clients to store the clock provider device and clock identity
  values separately. For simple clock consumers, this isolates clients
  from internal details of the clock API.
* clk.h is split so it only contains the client/consumer API, whereas
  clk-uclass.h contains the provider API. This aligns with the recently
  added reset and mailbox APIs.
* clk_ops .of_xlate(), .request(), and .free() are added so providers
  can customize these operations if needed. This also aligns with the
  recently added reset and mailbox APIs.
* clk_disable() is added.
* All users of the current clock APIs are updated.
* Sandbox clock tests are updated to exercise clock lookup via DT, and
  clock enable/disable.
* rkclk_get_clk() is removed and replaced with standard APIs.

Buildman shows no clock-related errors for any board for which buildman
can download a toolchain.

test/py passes for sandbox (which invokes the dm clk test amongst
others).

89c1e2da78 Add a reset driver framework/uclass
A reset controller is a hardware module that controls reset signals that
affect other hardware modules or chips.

This patch defines a standard API that connects reset clients (i.e. the
drivers for devices affected by reset signals) to drivers for reset
controllers/providers. Initially, DT is the only supported method for
connecting the two.

The DT binding specification (reset.txt) was taken from Linux kernel
v4.5's Documentation/devicetree/bindings/reset/reset.txt.

1e6fb0e367 usb: ehci: only shutdown opened controller
If the usb controller is not running, no need to shutdown it,
otherwise `usb stop` complains about:
"EHCI failed to shut down host controller".

To i.MX7D SDB, there are two usb ports, one Host, one OTG.
If we only plug one udisk to the Host port and then `usb start`,
the OTG controller for OTG port does not run actually. Then,
if `usb stop`, the OTG controller for OTG port will also be
shutdown, but it is not running.

This patch adds a check to only shutdown the running controller.

 - Pin's PADs only gets configured when GPIO driver is probed, which
   is not done by default. This leaves the board in a partially
   functional state as we must initialize PADs correctly to get
   perepherals fully working.
 - The probe routine of pinctrl driver is called multiple times, as
   normally there are multiple GPIO controllers. It should really
   be called just once.

Move the call to syscon_get_by_driver_data() from ich6_gpio driver
to cpu_init_r().

8142340ee3 x86: ich6_gpio: Output return value of syscon_get_by_driver_data()
The call to syscon_get_by_driver_data() does not save its return value.
Print it out to aid debugging.

e19b900457 spi: pic32_spi: add SPI master driver for PIC32 SoC.
This driver implements SPI protocol in master mode to communicate
with the SPI device connected on SPI bus. It handles /CS explicitly
by controlling respective pin as gpio ('cs-gpios' property in dt node)
and uses PIO mode for SPI transaction. It is configurable based
on driver-model only.

bca4c3c5fc sunxi: musb: Properly turn of musb controller before booting
Turn of the clock and assert the reset when musb_stop gets called, so that
the os gets the musb controller in a pristine state. This fixes a spurious
VBus error interrupt triggering as soon as the Linux musb driver loads.
