From 81b3b2711072b6047d5f332cd8751a1c5c9a3fb2 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 28 Jan 2014 12:36:48 +0100 Subject: clocksource: sh_cmt: Add support for multiple channels per device CMT hardware devices can support multiple channels, with global registers and per-channel registers. The sh_cmt driver currently models the hardware with one Linux device per channel. This model makes it difficult to handle global registers in a clean way. Add support for a new model that uses one Linux device per timer with multiple channels per device. This requires changes to platform data, add new channel configuration fields. Support for the legacy model is kept and will be removed after all platforms switch to the new model.
