This is an RFC for a series of patch to add the support of MIPI HSI and SSI devices to OMAP platforms. The patch includes the HSI device driver and the device files for MIPI HSI and SSI. The driver is made of 2 distinct modules: - omap_hsi: is the Low-Level Driver (or hardware driver). It provides a kernel functional interface, to be used by other kernel modules and abstracts the HW. This part of the patch is based on Nokia SSI driver, already submitted as RFC by Carlos Chinea [1]. - hsi-char: is a char device driver proposing a user-space interface for using the HSI and relies on omap_hsi. This part of the patch is based on a development from Andras Domokos. The intent is to propose a single HSI driver that can support MIPI HSI 1.1 as well as previous implementations (SSI) for OMAP platforms (OMAP3 / OMAP4). The driver core functionalities are there and ready for review. The following updates will come in the following weeks / months: - Clocks and Power Management support for OMAP4 platform (HSI device file) - HSI-char interface documentation Validation: The driver is validated on 3430 SDP (with a HW loopback on the SSI device), and is being validated on 4430 Virtio platform (MIPI HSI device).
