4e36425115 arm: dts: imx: fsl-imx8dx.dtsi: add gpio aliases to fix gpio command
The gpio command currently uses equal bank names "GPIO0_"
for all existing gpio banks, i. e.:

U-Boot# gpio status -a
Bank GPIO0_:
GPIO0_0: input: 0 [ ]
GPIO0_1: output: 1 [x] dbg1.gpios
...

Bank GPIO0_:
GPIO0_0: input: 0 [ ]
GPIO0_1: input: 0 [ ]
...

So the command is broken, it is not possible to address
a desired bank. Add gpio aliases to fix this.

1b8c986b68 IMX: serial: dm: Set DM_FLAG_PRE_RELOC in the IMX uart driver
The DM_FLAG_PRE_RELOC shall be set unconditionally as this driver is going
to be re-used in both early SPL and U-Boot proper's pre-reloc.

For i.MX based devices it is crucial to have available the serial console
before relocation (otherwise the board may hand).

The device definition may be provided either via device tree description or
with U_BOOT_DEVICE(mxc_serial) definition. In the latter case the device
will not bind in U-Boot proper when DM_FLAG_PRE_RELOC is not set.

The !CONFIG_IS_ENABLED(OF_CONTROL) #if check was set as a "workaround" for
DM problem described in following commit 4687919684
("serial: Remove DM_FLAG_PRE_RELOC flag in various drivers").

Let's look on this check more thoroughly - we add this flag if the board
doesn't support OF_CONTROL. This is a bit strange as the serial_mxc.c can
be used with CONFIG_DM_SERIAL but without corresponding device tree
description (OF_CONTROL). In such case the aforementioned
U_BOOT_DEVICE(mxc_serial) definition is used.

Other boards/SoCs have this flag set unconditionally for serial driver.

06fc74102a mx7ulp_evk: Update DDR freq to 352.8Mhz for ULP B0
On i.MX7ULP B0, the DDR clock target is increased from 320Mhz to 380Mhz.
We update DDR clock relevant settings to approach the target. But since the
limitation on LCDIF pix clock for HDMI output
(refer "mx7ulp_evk: Change APLL and its PFD0 frequencies"), we set DDR
clock to 352.8Mhz (25.2Mhz * 14) by using the clock path:

	APLL PFD0 -> DDR CLK -> NIC0 -> NIC1 -> LCDIF clock

To reduce the impact to entire system, the NIC0_DIV and NIC1_DIV are kept,
so the divider 14 is calculated as:
	14 = (NIC0_DIV + 1) * (NIC1_DIV + 1) * (LCDIF_PCC_DIV + 1)

	NIC0_DIV:      1
	NIC1_DIV:      0
	LCDIF_PCC_DIV: 6

APLL and APLL PFD0 settings:

	PFD0 FRAC:  27
	APLL MULT:  22
	APLL NUM:   1
	APLL DENOM: 20

This patch applies the new settings for both DCD and plugin.
There is no DDR script change on this new frequency.
Overnight memtester is passed.

285aea01d2 mx7ulp_evk: Change APLL and its PFD0 frequencies
To support HDMI display on EVK board, the LCDIF pix clock must be
25.2Mhz. Since the its PCC divider range is from 1-8, the max rate
of LCDIF PCC source clock is 201.6Mhz. This limits the source clock
must from NIC1 bus clock or NIC1 clock, other sources from APLL PFDs
are higher than this max rate.

The NIC1 bus clock and NIC1 clock are from DDRCLK whose parent source
is APLL PFD0, so we must change the APLL PFD0 and have impact to DDRCLK,
NIC1 and NIC1 bus.

Eventually, this requests to set the APLL PFD0 frequency to 302.4Mhz
(25.2 * 12), with settings:

PFD0 FRAC:  32
APLL MULT:  22
APLL NUM:   2

72a9414bd4 mx7ulp: Fix APLL num and denom setting issue
For the current APLL setting, as we want the APLL PFD0 to meet DDR clock 320Mhz requirement.
We set MULT to 20, NUM to 4 and DENOM to 2, to get final 22 multiplier. But according to the RM,
the NUM should always be less than the DENOM. So our setting violates the rule.

Actually the ROM has already set the MULT to 22 and leave NUM/DENOM in default value. The calculated APLL PFD0 clock
is 318.9888Mhz, which also meet the DDR requirement.
To fix the issue, we remove the PLL settings in DCD to use default value from ROM, and only set the PFD0 FRAC.

Add regulator driver for ROHM BD71837 and BD71847 PMICs.
BD71837 contains 8 bucks and 7 LDOS. BD71847 is reduced
version containing 6 bucks and 6 LDOs. Voltages for DVS
bucks (1-4 on BD71837, 1 and 2 on BD71847) can be adjusted
when regulators are enabled. For other bucks and LDOs we may
have over- or undershooting if voltage is adjusted when
regulator is enabled. Thus this is prevented by default.

BD718x7 has a quirk which may leave power output disabled
after reset if enable/disable state was controlled by SW.
Thus the SW control is only allowed for BD71837  bucks
3 and 4 by default. The impact of this limitation must be
evaluated board-by board and restrictions may need to be
modified. (Linux driver get's these limitations from DT and we
may want to implement same on u-Boot driver).
