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 patch targets PHYTEC specific config creation. Until now
PHYTEC used to patch the default 'imx_v7_defconfig' with their changes.
This patch introduces PHYTEC specific i.MX6 SoM config fragment which
should be merged with the default 'imx_v7_defconfig' to create a
complete config file. This mainly minimizes efforts required to port
patches to defconfig with each new PHYTEC BSP release and uniforms
config creation between PHYTEC's kernel and barebox.
3. The last three patches (third, fourth and fifth) 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@xxxxxxxxxx: 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
P.S. I cc-ed some PHYTEC guys so they can be involved in the discussion
if necessary.
