Instructions on EINT configuration for SIM hot swap for MT6575/MT6577 platforms

方法如下：

For MT6575/MT6577 ICS2/JB version:

You need patch: ALPS00368898. Before configuring SIM hot swap, check if your company
has already applied the patch. According to hardware, configure “ALPS” AP side DCT
tool (the .dws file).
We suggest you:
1.Configure EINT to trigger “insert SIM card” state, H or L. For example: If “insert
SIM card” state is H (high), configure to trigger H (high).
2.Use level trigger (must be set to “Debounce time”; “Debounce time” must > 7). The
“Debounce time” value will be transferred to the Modemside then
“EINT_SW_Debounce_Modify()” for SW de-bounce time setting. The unit is 10ms.
“Debounce time: 7” -> 7*10=70ms. For modem side, the SW de-bounce time should be
longer than the default HW de-bounce time which is 63ms.
3.Modify source code “custom_sim_driver.c” of “modem”.
custom_sim_driver.c(MAUI\custom\drv\misc_drv\$(customer project)) 11AMDW**SP
sim_hot_plug_eint_cb_rm_h_common()
sim_hot_plug_eint_cb_rm_l_common()
Example:
GPI069 -> EINT3 mode
GPIO72 -> EINT4 mode
SIM1hot swap detect pin usesEINT No.3.
SIM2 hot swap detect pin uses EINT No.4.
High level -> Insert SIM card(card)
Low level -> Remove SIM card(no card)

Before configuring SIM hot swap, check if your company has already applied patch
ALPS00368898. If not, submit e-service to apply for the patch.
ALPS00368898 includes ALPS00368898 and MAUI_03236293. (Set SIM_HOT_SWAP = SIM_SLOT_1 in
modem makefile.)
After you get the patch, check modem patch makefile SIM_HOT_SWAP. If SIM_HOT_SWAP =
NONE, remind your MediaTek window that MAUI_03236293 should be set as SIM_HOT_SWAP =
SIM_SLOT_1 to build.

The definitions of AP and modem EINT pin on “level trigger” and “edge trigger” are
opposite.
AP:
level trigger(define: 1 -> TRUE)
edge trigger(define: 0 -> FALSE)
Modem:
level trigger(define: 0 -> FALSE)
edge trigger(define: 1 –> TRUE)
Modify function sim_reg_hot_plug_eint() of custom_sim_driver.c according to the AP
configuration in modem side hardcore.
