The sh_mtu2 driver gets the MTU2 functional clock using a connection ID of "mtu2_fck". While all SH SoCs create clock lookup entries with a NULL device ID and a "mtu2_fck" connection ID, the ARM SoCs use the device ID only with a NULL connection ID. This works on legacy platforms but will break on ARM with DT boot. Fix the situation by using a connection ID of "fck" in the non-legacy platform data case. Clock lookup entries will be renamed to use the device ID as well as the connection ID as platforms get moved to new platform data. The legacy code will eventually be dropped, leaving us with device ID based clock lookup, compatible with DT boot. Signed-off-by:

MTU2 hardware devices can support multiple channels, with global registers and per-channel registers. The sh_mtu2 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. Signed-off-by:

The driver claims it needs to register an interrupt handler too early for request_irq(). This might have been true in the past, but the only meaningful difference between request_irq() and setup_irq() today is an additional kzalloc() call in request_irq(). As the driver calls kmalloc() itself we know that the slab allocator is available, we can thus switch to request_irq(). Signed-off-by:
