Switch_ON(): detect charging mode by CHGPRES bit
Consider the following scenario: the phone is on, the user plugs in
the charger, and then executes the power-off operation. In the Iota
VRPC this sequence translates to a switch-off immediately followed
by another switch-on - but the CHGSTS bit doesn't get set on the second
switch-on cycle! Disassembly of Pirelli's fw shows that they check
the CHGPRES bit, and furthermore, if both CHGPRES and ONBSTS are set,
the code they pass to their modified Power_ON_Button() function is
the one for charging - so let's adopt the same CHGPRES check and
the same priority order for switch-on causes.

/* * The only DSP patch code we have for 36_10 is the dynamic download version * which we have extracted from the world's last surviving copy of TCS211 fw * for Calypso modems. The purpose of this cheesy patch_file36_10.c wrapper * is to allow experimental builds with L1_DYN_DSP_DWNLD=0: we use the static * portion of our only available patch code, and simply not do the dynamic part. * * This configuration is intended only for experiments, not for production! * The dynamic parts of the DSP patch code which this configuration omits * are surely there for some good reason, and we can only guess what we are * going to destabilize by disabling them. */ #include "patch_file36_10_dyn_dwl.c"
