* serial: sh-sci: Abstract register maps.Paul Mundt2011-06-141-0/+1
| | | | | | | | | | | | | | | This takes a bit of a sledgehammer to the horribly CPU subtype ifdef-ridden header and abstracts all of the different register layouts in to distinct types which in turn can be overriden on a per-port basis, or permitted to default to the map matching the port type at probe time. In the process this ultimately fixes up inumerable bugs with mismatches on various CPU types (particularly the legacy ones that were obviously broken years ago and no one noticed) and provides a more tightly coupled and consolidated platform for extending and implementing generic features.

| * | serial: sh-sci: Move SCBRR calculation algo in to platform data.Paul Mundt2009-06-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | This permits each port to select its own SCBRR calculation algorithm, rather than having it all ifdef'ed in the header. There are presently only 5 different variations that all parts fall under. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* | | sh: sh7366 Enable SDIO IRQsMagnus Damm2011-01-121-10/+14
| |/ |/| | | | | | | | | | | | | | | | | This patch enables interrupt generation for SDIO IRQs of the SDHI block on the sh7366 processor. Use together with a recent SDHI driver using TMIO_MMC_SDIO_IRQ and with the MMC_CAP_SDIO_IRQ flag in the board code.

* | sh: sh7366 clock string death.Paul Mundt2010-03-291-4/+0Star

* | serial: sh-sci: clkdev updates for MSTP gating.Paul Mundt2010-03-101-1/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes up some of the I/D/F clock ambiguity in the sh-sci driver. The interface clock in most cases just wraps back to the peripheral clock, while the function clock wraps in to the MSTP bits. As the logic was somewhat inverted, this cleans that up, and also enables all CPUs with SCI MSTP bits to match function clocks through clkdev lookup. As a result, this gets rid of the clk string abuse on the sh side, and the clock string will be killed off once the ARM code has had a chance to sync up. This also enables MSTP gating on CPUs like 7786 which had never wired it up before. Impacted CPUs are primarily all SH-Mobiles, SH7785, and SH7786. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch breaks out the sh4a scif serial port platform data from a shared platform device to one platform device per port. Also, add serial ports to the list of early platform devices. Only sh4a SuperH Mobile processors are modified by this patch.

* | sh: convert processor device setup functions to arch_initcall()Magnus Damm2009-07-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert the processor platform device setup functions from __initcall() and sometimes device_initcall() to arch_initcall(). This makes sure that the platform devices are registered a bit earlier so the devices are available when drivers register using initcall levels earlier than device_initcall(). A good example is platform devices needed by i2c-sh_mobile.c which registers a bit earlier using subsys_initcall().

* | usb: r8a66597-hcd platform data on_chip supportMagnus Damm2009-07-191-1/+1
|/ | | | | | | | | | | | | | | | Convert the r8a66597-hcd driver to use the on_chip flag from platform data to enable on chip behaviour instead of relying on CONFIG_SUPERH_ON_CHIP_R8A66597 ugliness. This makes the code cleaner and also allows us to support both external and internal r8a66597 with the same kernel. It also makes the Kconfig part more future proof since we with this patch can add support for new processors with on-chip r8a66597 without modifying the Kconfig.
