Hi all,

this patch series contains PHYTEC barebox patches which weren't yet
introduced to this mailing list (or at least not in this form).

 1. The first patch increases the stability during boot in extreme cold
 conditions.

 2. The second and third patch adds some missing configs (OCOTP write
 support and some OF commands).

 3. The last three patches (fourth, fifth and sixth) are meant as a
 fixup for patches that deleted the PMIC supply nodes. They were
 introduced because barebox doesn't support DA9063 PMIC regulator driver
 and instead prints ugly warnings (recently downgraded from error) like:

imx-esdhc 2194000.mmc@2194000.of: Failed to get 'vmmc' regulator (ignored).

 In either way, we rely on PMIC's reset default and use dummy
 regulators. Using barebox specific device-tree property
 ('barebox,allow-dummy-supply') shouldn't break booting Linux with
 barebox internal device-tree and allows using dummy regulators in
 bootloader where regulator support is limited. The complete solution
 would be porting DA9063 regulator driver to barebox, but let's add that
 to our "to-do" list for now and use this workaround instead.

Best regards,
Andrej

Changes in v2:
 - remove "PHYTEC specific" config patch. Drop removing IPUV3 driver and move
 enabled configs to default imx_v7_defconfig,
 - move "barebox,allow-dummy-supply" to be added to regulator provider

To increase stability during boot in cold conditions (< -30 °C) increase
the SOC voltage from 1.15 V to 1.25 V in DCD. The ARM voltage is left
unchanged at its default 1.15 V.

The idea of devicetree property which allows use of dummy regulator is
not new but has not been implemented until now.
This implementation uses barebox specific devicetree property
"barebox,allow-dummy-supply" to allow switching to a dummy power
regulator in cases where proper regulator driver is not available. This
property can be set for regulator or for PMIC regulators nodes, which
then allow use of dummy regulator for all its child nodes. Basically
just catch the regulators ensure_probed error, if
"barebox,allow-dummy-supply" property is set and return dummy regulator.

The power for the phyFLEX sd cards and ethernet controller are supplied
by the DA9063 PMIC's LDOs. There is no barebox driver for those LDO
regulators. Thus use dummy-regulators to suppress warning message.

This return, which was added in "common: add initial barebox
deep-probe support", is a memory leak of propname.  It should be goto
out.

You are right, if that's ok I will create a separate patch for that.
