HSI: Introduce OMAP SSI driver Add OMAP SSI driver to the HSI subsystem. The Synchronous Serial Interface (SSI) is a legacy version of HSI. As in the case of HSI, it is mainly used to connect Application engines (APE) with cellular modem engines (CMT) in cellular handsets. It provides a multichannel, full-duplex, multi-core communication with no reference clock. The OMAP SSI block is capable of reaching speeds of 110 Mbit/s.

HSI: omap-ssi: add COMMON_CLK dependency Enabling the omap ssi driver without COMMON_CLK results in a build failure: drivers/hsi/controllers/omap_ssi_core.c: In function 'ssi_clk_event': drivers/hsi/controllers/omap_ssi_core.c:304:7: error: 'PRE_RATE_CHANGE' undeclared (first use in this function) This adds a Kconfig dependency to avoid the invalid configuration.

SSI is a legacy version of HSI. It is usually used to connect
an application engine with a cellular modem.
If you say Y here, you will enable the OMAP SSI hardware driver.
If unsure, say N.
