6fcb2ee783 imx8: Replace SC_R_LAST with SC_R_NONE in DTB
We are currently using SC_R_LAST as a marker for imx8 power domain tree
nodes without a resource attached. This value is compiled into dtb as
part of the linux build and used by uboot.

The SC_R_LAST constant changes frequently as SCFW resources are added
(by design) and every time we need to update linux and uboot headers
together or boot can fail.

Fix this by replacing SC_R_LAST usage with a new constant SC_R_NONE
defined to be 0xFFF0.

1074af51ec power: imx8: Check owned resource in power on
When fspi is assigned to M4, we have to let the fspi probe failed when
its power domain is failed to power up. Because not all devices have power
domain (for example, external devices on the board). Current checking
resource owner in power domain probe is not good, change to check it in
power on.

e8f8b5ccf2 power: imx8: remove the resource owned check before power off
For all the devices used and set ACTIVE in U-Boot, U-Boot needs
to power off all of them without the check of resource owner.

When we create software partition before booting Linux, the resource
own checkw will return false, and cause the power domain not powered
off. If without the check of resource owner, the power domain in
the other software partition could be powered off with parent
partition could access child partition resources.

If without this flag, calling dev_power_domain_ctrl will iteratively remove
the power domain device will causes iteratively power off parent PD. This is
not expected by imx8-power-domain-legacy driver. Power off parent PD is
controlled by the driver internally.

So set DM_FLAG_DEFAULT_PD_CTRL_OFF to avoid such issue

8c0a1c6de8 imx8: power: Add PD device lookup interface to power domain uclass
Add power_domain_lookup_name interface to power domain uclass to find
a power domain device by its DTB node name, not using its associated
client device.

Through this interface, we can operate the power domain devices directly.
This is needed for non-DM drivers.

Modified from Ye's NXP downstream patch

to use new power domain driver.

i.MX6QP and i.MX7D BCH module integrated a new feature to detect the
bitflip number for erased NAND page. So for these two platform, set the
erase threshold to gf/2 and if bitflip detected, GPMI driver will
correct the data to all 0xFF.

Also updated the imx6qp dts file to ditinguish the GPMI module for i.MX6Q

-----------------------------------------------------------------

This patch does a check for the uncorrectable failure in the following steps:

   [0] set the threshold.
       The threshold is set based on the truth:
       "A single 0 bit will lead to gf_len(13 or 14) bits 0 after the BCH
        do the ECC."

        For the sake of safe, we will set the threshold with half the gf_len, and
        do not make it bigger the ECC strength.

   [1] count the bitflips of the current ECC chunk, assume it is N.

   [2] if the (N <= threshold) is true, we continue to read out the page with
       ECC disabled. and we count the bitflips again, assume it is N2.
       (We read out the whole page, not just a chunk, this makes the check
        more strictly, and make the code more simple.)

   [3] if the (N2 <= threshold) is true again, we can regard this is a erased
       page. This is because a real erased page is full of 0xFF(maybe also has
       several bitflips), while a page contains the 0xFF data will definitely
       has many bitflips in the ECC parity areas.

   [4] if the [3] fails, we can regard this is a page filled with the '0xFF'
       data.

616f03daba mtd: gpmi: change the BCH layout setting for large oob NAND
The code change updated the NAND driver BCH ECC layout algorithm to
support large oob size NAND chips(oob > 1024 bytes) and proposed a new
way to set ECC layout.

Current implementation requires each chunk size larger than oob size so
the bad block marker (BBM) can be guaranteed located in data chunk. The
ECC layout always using the unbalanced layout(Ecc for both meta and
Data0 chunk), but for the NAND chips with oob larger than 1k, the driver
cannot support because BCH doesn’t support GF 15 for 2K chunk.

The change keeps the data chunk no larger than 1k and adjust the ECC
strength or ECC layout to locate the BBM in data chunk. General idea for
large oob NAND chips is

1.Try all ECC strength from the minimum value required by NAND spec to
the maximum one that works, any ECC makes the BBM locate in data chunk
can be chosen.

2.If none of them works, using separate ECC for meta, which will add one
extra ecc with the same ECC strength as other data chunks. This extra
ECC can guarantee BBM located in data chunk, of course, we need to check
if oob can afford it.

Previous code has two methods for ECC layout setting, the
legacy_calc_ecc_layout and calc_ecc_layout_by_info, the difference
between these two methods is, legacy_calc_ecc_layout set the chunk size
larger chan oob size and then set the maximum ECC strength that oob can
afford. While the calc_ecc_layout_by_info set chunk size and ECC
strength according to NAND spec. It has been proved that the first
method cannot provide safe ECC strength for some modern NAND chips, so
in current code,

1. Driver read NAND parameters first and then chose the proper ECC
layout setting method.

2. If the oob is large or NAND required data chunk larger than oob size,
chose calc_ecc_for_large_oob, otherwise use calc_ecc_layout_by_info

3. legacy_calc_ecc_layout only used for some NAND chips does not contains
necessary information. So this is only a backup plan, it is NOT
recommended to use these NAND chips.

5fe419ef2a net: Add eth phy generic driver for shared MDIO
For dual ethernet controllers, the HW design may connect ETH phys to
one MDIO ports. So two different ethernet drivers have to share MDIO bus.
Since two ethernet drivers are independent, we can't ensure their probe
order.

To resolve this problem, introduce an eth phy generic driver and uclass.

After eth-uclass binds, we search the mdio node and binds the phy node
with the eth-phy-generic driver.

When one eth driver get its phy device, the parent of phy device will
probe prior than phy device. So this ensure the eth driver ownes the
MDIO bus will be probed before using its MDIO.

6333cbb381 phy: atheros: ar8035: remove static clock config
We can configure the clock output in the device tree. Disable the
hardcoded one in here. This is highly board-specific and should have
never been enabled in the PHY driver.

If bisecting shows that this commit breaks your board it probably
depends on the clock output of your Atheros AR8035 PHY. Please have a
look at doc/device-tree-bindings/net/phy/atheros.txt. You need to set
"clk-out-frequency = <125000000>" because that value was the hardcoded
value until this commit.

fe6293a809 phy: atheros: add device tree bindings and config
Add support for configuring the CLK_25M pin as well as the RGMII I/O
voltage by the device tree.

By default the AT803x PHYs outputs the 25MHz clock of the XTAL input.
But this output can also be changed by software to other frequencies.
This commit introduces a generic way to configure this output.

Also the PHY supports different RGMII I/O voltages: 1.5V, 1.8V and 2.5V.
An internal LDO is able to provide 1.5V (default) and 1.8V. The 2.5V
option needs an external supply voltage. This commit adds support to
switch the internal LDO to 1.8V.
