[PATCH v1 00/43] ep93xx device tree conversion

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

This series aims to convert ep93xx from platform to full device tree support.

Alexander, Kris - there are some significant changes in clk and pinctrl so can i ask you to tests all once again.

So i am not applying:

Major changes from v0 to v1:

- I totally forgot to include dts bindings for USB, they are working, including in this version
- retinkered ep93xx keypad, the stange thing about it that it always used zeroed 
  platform data from the very beginning - my first impulse was to remove it entirely, espesially 
  it's ep9307+ variant, which Alexander and me doesn't have
- major YAML bindings overhaul according to Krzysztof comments
- nand helper converted to LEGACY nand controller
- cleanup clk
- cleanup pinctrl

Sorry if i missed something, first time handling such a big (at least for me) chunk of patches.

Next version should be much faster spin.

Alexandre Belloni:
 st,m48t86 is totally trivial, but it has 2 regs instead of one, so dt_binding_check doesn't allow it in trivial.yaml,
 regs should be increased to "maxItems: 2"

Miquel Raynal:
 Currently made it LEGACY as a more easier way for now, as this series will merge - it will be much 
 easier to cleanup the rest one by one, i hope it's ok.
 
Stephen Boyd:
 Majory of issues fixed, but:
     - removing dma from init section requires converting it from half dt/platform monstrosity 
       into fully dt compatible
     - i would like to have ep93xx_clk_data and ep93xx_map global for now - they can be removed 
       once dma subsys_initcall removed

Andrew Lunn:
  I've tinkered with the preferred way, however this involves turning on
     - CONFIG_PHYLIB
     - CONFIG_MDIO_DEVICE

  And maybe CONFIG_MICREL_PHY (at least for me, unless i can use some
  common phy driver) which implies a kernel size increase - which is
  undesirable for us.
  
  Can we slip by getting phyid directly from device tree in ep93xx_eth ?
