Hi Alban,

thanks for the reply

first of i want to make it work inside LEDE but i do want to reduce our
technical debt this year so its a realistic option to send it upstream.
once it works with a hack i will draft a proper OF binding and fwd it to
get review comments before implementing it.

awesome, i just merged it to my test tree. i'll start working on the
pinctrl tomorrow in that case.

great !

please CC me on the mails so i am up to date and can adopt the patches
as early as possible

there are boards using PCI/e. i will have a closer look at PCI and see
if it is also a DW variant.

could you give a more detailed list of what clk and irq drivers are
missing ? i could help write the code, i am just scared to duplicate
some of your work.

apart from that, Thanks for sending this all upstream, i will be sending
a few minor patches that i created the last days in the coming days.
