      sunxi: axp209: fix incorrect limits on ldo3 · 99deda1d
      Iain Paton 提交于
      board/sunxi/board.c tries to set ldo3 to 2.8v however drivers/power/axp209.c
      contains an incorrect limit on ldo3 of 2.275v
      
      The origin of the incorrect limit seems likely due to some inconsistencies
      in the axp209 datasheet. ldo3 is described with different limits in
      different sections. register 0x29 uses 7 bits for voltage configuration
      while the 2.275v limit would apply if only 6 bits were used.
      Probably this is a cut&paste error from register 0x23
      
      The linux kernel driver has the correct limit and operation up to the 2.8v
      required by my board has been physically verified with a multimeter.

      sunxi: set GMAC TX delay = 0x1 on Cubietruck. · a923abc2
      Ian Campbell 提交于
      Of 4 boards in our automated test system 2 do not have reliable
      networking with the default TX delay of 0x0. Increasing to 0x1 seems
      to make things reliable on all 4 boards.
      
      Some previous ad-hpoc tests with tx delay set to 0, 1, 2 and 3 on one
      of the problematic boards showed:
      
      0: mw.l 0x1c20164 0x006 1     -- t/o in 4/5 tftp runs
      1: mw.l 0x1c20164 0x406 1     -- t/o in 1/5 tftp runs
      2: mw.l 0x1c20164 0x806 1     -- t/o in 1/5 tftp runs
      3: mw.l 0x1c20164 0xc06 1     -- t/o many times in first tftp run
      
      For 0, 1 and 2 "t/o" means one or two "T" glitches in the download,
      but it did complete. For 3 those were basically continuous and it
      couldn't complete.
      
      tftp was of a 16M initrd.
