While the R40 uses a different register for EMAC clock configuration
than other chips, the register has a very similar layout. Reuse the
existing bitfield definitions in this file, since they match.
This allows the driver to compile on the H6 platform, where the
CCM_GMAC_CTRL definitions are not present.

The regulator-fixed would return -ENOSYS when enabled/disabled,

Because of this commit :
5ae84860b0 ("misc: i2c_eeprom: verify that the chip is functional at probe()")
at probe time, each eeprom is tested for read at offset 0.
The Atmel AT24MAC402 eeprom has different mapping. One i2c slave address is
used for the lower 0x80 bytes and another i2c slave address is used for the
upper 0x80 bytes. Because of this basically the i2c master sees 2 different
slaves. We need the upper bytes because we read the unique MAC address from
this EEPROM area.
However this implies that our slave address will return error on reads
from address 0x0 to 0x80.
To solve this, implemented an offset field inside platform data that is by
default 0 (as it is used now), but can be changed in the compatible table.
The probe function will now read at this offset and use it, instead of blindly
checking offset 0.
This will fix the regression noticed on these EEPROMs since the commit
abovementioned that introduces the probe failed issue.

At present we still have pre-driver-model code in this driver and it makes
things a bit confusing. In particular calc_bus_speed() is called with priv
as NULL if not using driver model.
This results in spk_cnt and comp_param1 being read from an invalid address
if not using driver model. For comp_param1 this may not cause problems if
reading from addresses close to 0 happens to be allowed, as high speed is
only supported by DM code. But spk_cnt is subsequently used to calculate
the bus periods and so this may cause problems (e.g. on spear600 board
which has not been migrated yet).
Add a new parameter regs parameter to calc_bus_speed() and add more
comments to this function and to _dw_i2c_set_bus_speed(), which calls it.

The omap3.dtsi file shows the usbhshost node with two sub-nodes

pulls the portX-mode information. It then locates the EHCI
sub-node, and initializes the EHCI controller with the info
pulled from the usbhshost node.
There is still more to do since there isn't an actual link
between the 'phys' reference and the corresponding phy driver,
and there is no nop-xceiv driver yet.
In the meantime, the older style reference to
CONFIG_OMAP_EHCI_PHYx_RESET_GPIO is still needed to pull
the phy out of reset until the phy driver is completed and the
phandle reference is made.

Yes, it is possible to have a dedicated UCLASS PHY driver
for this Rockchip PCIe PHY but there are some issues on
Generic PHY framework to support the same.
The Generic PHY framework is unable to get the PHY if
the PHY parent is of a different uclass.
Say if we try to get the PCIe PHY then the phy-uclass
will look for PHY in the first instance if it is not
in the root node it will try to probe the parent by
assuming that the actual PHY is inside the parent PHY
of UCLASS_PHY. But, in rk3399 hardware representation
PHY like emmc, usb and pcie are part of syscon which
is completely a different of UCLASS_SYSCON.
Example:
grf: syscon@ff770000 {
compatible = "rockchip,rk3399-grf", "syscon", "simple-mfd";
reg = <0x0 0xff770000 0x0 0x10000>;
#address-cells = <1>;
#size-cells = <1>;
pcie_phy: pcie-phy {
compatible = "rockchip,rk3399-pcie-phy";
clocks = <&cru SCLK_PCIEPHY_REF>;
clock-names = "refclk";
#phy-cells = <1>;
resets = <&cru SRST_PCIEPHY>;
drive-impedance-ohm = <50>;
reset-names = "phy";
status = "disabled";
};
};
Due to this limitation, this patch adds a separate PHY
driver for Rockchip PCIe. This might be removed in future
once Generic PHY supports this limitation.

[ Linux commit 9afbe7c0140f663586edb6e823b616bd7076c00a ]
If the write protect signal from this IP is connected to the NAND
device, this IP can handle the WP# pin via the WRITE_PROTECT
register.
The Denali NAND Flash Memory Controller User's Guide describes
this register like follows:
When the controller is in reset, the WP# pin is always asserted
to the device. Once the reset is removed, the WP# is de-asserted.
The software will then have to come and program this bit to
assert/de-assert the same.
1 - Write protect de-assert
0 - Write protect assert
The default value is 1, so the write protect is de-asserted after
the reset is removed. The driver can write to the device unless
someone has explicitly cleared register before booting the kernel.
The boot ROM of some UniPhier SoCs (LD4, Pro4, sLD8, Pro5) is the
case; the boot ROM clears the WRITE_PROTECT register when the system
is booting from the NAND device, so the NAND device becomes read-only.
Set it to 1 in the driver in order to allow the write access to the
device.
