Out-of-the-box the analogue camera adapter fails detecting with the
following error:
[ 6.503046] adv7280 2-0021: adv7280_probe:Analog Device adv7280 not detected -6!
Unfortunately, the camera seems to be held in reset due to the BL_ON pin
not being serviced.
Fix this by hogging the camera_nreset aka BL_ON pin to output high.

This patch enables both RXC and TXC 2ns dll delay lines on the
KSZ9131 PHY. Both are neede because the i.MX8MM SoC is RGMII v1.3
compliant. This means we need the TXC delay of the PHY.

This commit adds two properties to control the RX DLL and TX DLL
2ns delay on RXC/TXC RGMII clock lines. This is especially needed
if the MAC does not provide TXC delay by itself.

With this patch one is able to control the rx dll and tx dll bypass
bits, hence the 2ns delay on rxc and txc lines in devicetree.

The RXC delay is provided in both PHYs used (KSZ9031 and KSZ9131)
on the PHY itself so it is not needed on the MAC.

The MAC of the i.MX6 SoC is compliant with RGMII v1.3. The KSZ9131 PHY
is like KSZ9031 adhering to RGMII v2.0 specification. This means the
MAC should provide a delay to the TXC line. Because the i.MX6 MAC does
not provide this delay this has to be done in the PHY.
This patch adds by default ~1.4ns delay to the TXC line. This should
be good for all boards that have all RGMII signals routed with the
same length.
The KSZ9131 has relatively high tolerances on skew registers from
MMD 2.4 to MMD 2.8. Therefore the new DLL-based delay of 2ns is used
and then as little as possibly subtracted from that so we get more
accurate delay. This is actually needed because the i.MX6 SoC has
an asyn skew on TXC from -100ps to 900ps.

The hardware of verdin has some bypass caps after the switch that
switches power to the sd-card. These caps are resulting in a slow
discharge.
Add off-on-delay to set a minimum off-time of the regulator so it
can fully discharge until it turns on again.

This commit basically deletes the devicetree for V1.0 Apalis iMX8
modules. It includes V1.1 devicetree then and only puts in the
differences and deletes the nodes that are not used in V1.0.
This is done to prevent code duplication and have better overview of
what has changed.

commit 2801b2f5fad3d1e9ea0ac8484584051071065645 upstream
The dynamic bursts mode allows to group together multiple words into a
single burst. To do so, it's necessary that words can be packed into the
32-bits FIFO entries, so we can't allow using this mode with bit_per_words
different to 8, 16 or 32.
This prevents shitfing out extra clock ticks for transfers with
bit_per_word values not aligned on 8 bits.
With that , we are sure that only the correct number of bits is
shifted out at each transfer, so we don't need to mask out the remaining
parts of the words.

Add a 'sleep' pinmuxing which prevents driving RGMII pins and backfeed the
unpowered Ethernet PHY.
When switching the Ethernet PHY supply off, it takes about 400 ms for
the PHY power to go down. So wait a minimum of 500 ms before reenabling
the PHY supply.

After the Ethernet PHY supply is enabled an RC holds the reset asserted
for about 120 ms. Reduce the time waited from 1000 ms to 200 ms which
should account for any possible tolerance.
U-Boot enables the PHY supply, switching it off in Linux with the RGMII
pins allready muxed creates backfeeding, thus set regulator-boot-on.
