HID: intel_ish-hid: Enhance API to get ring buffer sizes Added two APIs: - ishtp_cl_get_tx_free_buffer_size: This returns total size available for a client to queue TX data. - ishtp_cl_get_tx_free_rings: This returns total number of TX rings available for a client.

HID: intel_ish-hid: ISH Transport layer The ISH transport layer (ishtp) is a bi-directional protocol implemented on the top of PCI based inter processor communication layer. This layer offers: - Connection management - Flow control with the firmware - Multiple client sessions - Client message transfer - Client message reception - DMA for RX and TX for fast data transfer Refer to Documentation/hid/intel-ish-hid.txt for overview of the functionality implemented in this layer.
