ARM: OMAP AM33xx: powerdomains: add AM335x support
Add offset & mask fields to struct powerdomain In case of AM33xx family of devices, there is no consistency between PWRSTCTRL & PWRSTST register offsers in PRM space, for example - PRM_XXX PWRSTCTRL PWRSTST ======================================= PRM_PER_MOD: 0x0C, 0x08 PRM_WKUP_MOD: 0x04, 0x08 PRM_MPU_MOD: 0x00, 0x04 PRM_DEVICE_MOD: NA, NA And also, there is no consistency between bit-offsets inside PWRSTCTRL & PWRSTST register, for example - PRM_XXX LOGICRET MEMON MEMRET ======================================= GFX_PWRCTRL: 2, 17, 6 PER_PWRCTRL: 3, 25, 29 MPU_PWRCTRL: 2, 18, 22 WKUP_PWRCTRL: 3, NA, NA This means, we need to maintain and pass on all this information in powerdomain handle; so adding fields for, - PWRSTCTRL/ST register offset - Logic retention state mask - mem_on/ret/pwrst/retst mask Currently, this fields is only applicable and used for AM33XX devices.
