   3 Subject: platform/x86: pmc_atom: Match all Lex BayTrail boards with
   4  critclk_systems DMI table
   5
   6 The critclk_systems[] DMI match table already contains 2 Lex BayTrail
   7 boards and patches were just submitted to add 3 more entries for the
   8 following models: 3I380NX, 3I380A, 3I380CW.
   9
  10 Looking at: https://www.lex.com.tw/products/embedded-ipc-board/
  11 we can see that Lex BayTrail makes many embedded boards with
  12 multiple ethernet boards and none of their products are battery
  13 powered so we don't need to worry (too much) about power consumption
  14 when suspended.
  15
  16 Add a new DMI match which simply matches all Lex BayTrail boards and drop
  17 the 2 existing board specific quirks.
