The Lex 3I380NX industrial PC has 4 ethernet controllers on board
which need pmc_plt_clk0 - 3 to function, add it to the critclk_systems
DMI table, so that drivers/clk/x86/clk-pmc-atom.c will mark the clocks
as CLK_CRITICAL and they will not get turned off.
This commit is nearly redundant to 3d0818f5eba8 ("platform/x86:
pmc_atom: Add Lex 3I380D industrial PC to critclk_systems DMI table")
but for all Lex Baytrail devices.

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