#define VORTEX_CODEC_WRITE	0x00800000
#define VORTEX_CODEC_ADDSHIFT 	16

(0x80* 1) << VORTEX_CODEC_ADDSHIFT)  is equal to  VORTEX_CODEC_WRITE

May be au8810 use different set of MMIO to read/write and report
status of the audio codec and modem codec ?

au8810.h

#define VORTEX_MODEM_CTRL	0x291ac

Make sure you have a BACKUP of all your data before you peform testing
on the modem.

It's not easy to hack the modem since we don't have any datasheet of 
au8810 and MOT6269353. (AC-link between them)
