usb: dwc2: gadget: Accept LPM token when TxFIFO is not empty
Set GLPMCFG_LPM_ACCEPT_CTRL_ISOC bit in GLPMCFG register
to accept LPM token during ISOC transfers when TxFIFO is
not empty.
- Added two definitions.
#define GLPMCFG_LPM_ACCEPT_CTRL_CONTROL BIT(21)
#define GLPMCFG_LPM_ACCEPT_CTRL_ISOC BIT(22)
This patch uses GLPMCFG_LPM_ACCEPT_CTRL_ISOC.
GLPMCFG_LPM_ACCEPT_CTRL_CONTROL is defined for further use.
- Added setting GLPMCFG_LPM_ACCEPT_CTRL_ISOC bit in GLPMCFG
register in dwc2_gadget_init_lpm function.
