bd70f3cea3 net: mediatek: add support for SGMII 1Gbps auto-negotiation mode
Existing SGMII support of mtk-eth is actually a MediaTek-specific
2.5Gbps high-speed SGMII (HSGMII) which does not support
auto-negotiation mode.

This patch adds SGMII 1Gbps auto-negotiation mode and rename the
existing HSGMII to 2500basex.

c41a058fb2 net: mediatek: optimize the switch reset delay wait time
Not all switches requires 1 second delay after deasserting reset.
MT7531 requires only maximum 200ms.

This patch defines dedicated reset wait time for each switch chip, and will
significantly improve the boot time for boards using MT7531.

c73d38719f net: mediatek: connect switch to PSE only when starting eth is requested
So far the switch is initialized in probe stage and is connected to PSE
unconditionally. This will cause all packets being flooded to PSE and may
cause PSE hang before entering linux.

This patch changes the connection between switch and PSE:
- Still initialize switch in probe stage, but disconnect it with PSE
- Connect switch with PSE on eth start
- Disconnect on eth stop

7cb50cd477 pinctrl: mediatek: convert most definitions to const
There exists a situation of the mediatek pinctrl driver that may return
wrong pin function value for the pinmux driver:
- All pin function arrays are defined without const
- Some pin function arrays contain all-zero value, e.g.:
  static int mt7622_spi_funcs[] = { 0, 0, 0, 0, 0, 0, };
- These arrays will be put into .bss section during compilation
- .bss section has no "a" attribute and does not exist in the final binary
  file after objcopy.
- FDT binary blob is appended to the u-boot binary, which occupies the
  .bss section.
- During board_f stage, .bss has not been initialized, and contains the
  data of FDT, which is not full-zero data.
- pinctrl driver is initialized in board_f stage, and it will get wrong
  data if another driver is going to set default pinctrl.

Since pinmux information and soc data are only meant to be read-only, thus
should be declared as const. This will force all pinctrl data being put
into .rodata section. Since .rodata has "a" attribute, even the all-zero
data will be allocated and filled with correct value in to u-boot binary.

b43512d046 spi: mtk_spim: clear IRQ enable bits
In u-boot we don't use IRQ. Instead, we poll busy bit in SPI_STATUS.

However these IRQ enable bits may be set in previous boot stage (BootROM).

If we leave these bits not cleared, although u-boot has disabled IRQ and
nothing will happen, the linux kernel may encounter panic during
initializing the spim driver due to IRQ event happens before IRQ handler
is properly setup.

This patch clear IRQ bits to prevent this from happening.

bff002d45b video: vesa: Use mtrr_set_next_var() for graphics memory
At present this uses mtrr_add_request() & mtrr_commit() combination
to program the MTRR for graphics memory. This usage has two major
issues as below:

- mtrr_commit() will re-initialize all MTRR registers from index 0,
  using the settings previously added by mtrr_add_request() and saved
  in gd->arch.mtrr_req[], which won't cause any issue but is unnecessary
- The way such combination works is based on the assumption that U-Boot
  has full control with MTRR programming (e.g.: U-Boot without any blob
  that does all low-level initialization on its own, or using FSP2 which
  does not touch MTRR), but this is not the case with FSP. FSP programs
  some MTRRs during its execution but U-Boot does not have the settings
  saved in gd->arch.mtrr_req[] and when doing mtrr_commit() it will
  corrupt what was already programmed previously.

Correct this to use mtrr_set_next_var() instead.

185571b6ec usb: dwc3-generic: Restrict single ctrl node for RK3328
Like Rockchip RK3568, the RK3328 also have single node to
represent the glue and ctrl for USB 3.0.

So, use the driver data to use single ctrl for RK3328 DWC3.

fea7a29cc8 power: regulator: rk8xx: Add 500us delay after LDO regulator is enabled
A quick power cycle of a LDO regulator during dw-mmc signal voltage
change has shown that SD-card does not always get recognized.

Linux driver use an enable_time of 400us for LDO regulators. Apply a
500us delay when a LDO regulator is enabled to fix possible issues.

414236b887 i2c: i2c-gpio: Correctly handle new {sda, scl}-gpios bindings
gpio_request_list_by_name() returns the number of gpios requested.
Notably it swallows the underlying -ENOENT when the "gpios" property
does not exist.

Update the i2c-gpio driver to check for ret == 0 before trying the new
sda-gpios/scl-gpios properties.

6913c30516 usb: dwc3-generic: Relax unsupported dr_mode check
When dr_mode is peripheral or otg and U-Boot has not been built with
DM_USB_GADGET support, booting such device may end up with:

  dwc3_glue_bind_common: subnode name: usb@fcc00000
  Error binding driver 'dwc3-generic-wrapper': -6
  Some drivers failed to bind
  initcall sequence 00000000effbca08 failed at call 0000000000a217c8 (err=-6)
  ### ERROR ### Please RESET the board ###

Instead fail gracfully with ENODEV to allow board continue booting.

  dwc3_glue_bind_common: subnode name: usb@fcc00000
  dwc3_glue_bind_common: unsupported dr_mode 3

Also use CONFIG_IS_ENABLED(USB_HOST) and change switch to if statements
to improve readability of the code.

4412a2bf0b usb: dwc3-generic: Return early when there is no child node
The current error check for device_find_first_child is not working as
expected, the documentation for device_find_first_child mention:

  @devp: Returns first child device, or NULL if none
  Return: 0

Change to return early when there is no child node to avoid any possible
null pointer dereference.
