[SIM] SIM hot swap EINT module configuration for MT6572/MT6582/MT6592/MT6571

[Description]

Smart phone SIM hot swap EINT module configuration for MT6572/MT6582/MT6592/MT6571

platforms.

In MT6572/MT6582/MT6592/MT6571 there is one internal modem, modem1. You can find “MD_1_EINT

Setting” in DCT tool (codegen.dws).

[Solution]

- MT6572/MT6582/MT6592/MT6571

AP own EINT module -> "EINT Setting"

Modem1 ownEINT module -> "MD1_EINT Setting"

Configure according to your schematic design.

Example:

MT6592

GPIO14 -> MD_EINT2 mode

GPIO15 -> MD_EINT3 mode

SIM1hot swap detect pin usesMD_EINT No.1.

SIM2 hot swap detect pin uses MD_EINT No.2.

High level -> Insert SIM card(card)

Low level -> Remove SIM card(no card)

The number of “MD_EINT” in “GPIO Setting” is different from the number of “EINT” in “EINT Setting”.

--------------------------------------------------------------------------------------

MT6572:

“MD_EINT” mode number selected in “GPIO Setting”EINT number in “MD1_EINT Setting”

MD_EINT0 -> MD1_EINT0

MD_EINT1 -> MD1_EINT1

MD_EINT2 -> MD1_EINT2

--------------------------------------------------------------------------------------

MT6582/MT6592/MT6571:

“MD_EINT” mode number selected in “GPIO Setting”EINT number in “MD1_EINT Setting”

MD_EINT1 -> MD1_EINT0

MD_EINT2 -> MD1_EINT1

MD_EINT3 -> MD1_EINT2

--------------------------------------------------------------------------------------

dct tool path:

\alps\mediatek\dct\DrvGen.exe

codegen.dws path:

\alps\mediatek\custom\${custom project}\kernel\dct\dct\codegen.dws

Double click on “DrvGen.exe” in Windows; open “codegen.dws” to edit it.

Once the editing is done, click on OK -> Gen Code -> Save.

Build command:

./makeMTK n lk k

./makeMtk bootimage

On MT6592 platform, in “modem EINT module”, software does not support “edge” trigger.
