2019-10-07sh: add the sh_ prefix to early platform symbolsBartosz Golaszewski1-1/+1
Old early platform device support is now sh-specific. Before moving on to implementing new early platform framework based on real platform devices, prefix all early platform symbols with 'sh_'.

2019-10-07drivers: move the early platform device support to arch/shBartosz Golaszewski1-0/+1
SuperH is the only user of the current implementation of early platform device support. We want to introduce a more robust approach to early probing. As the first step - move all the current early platform code to arch/sh. In order not to export internal drivers/base functions to arch code for this temporary solution - copy the two needed routines for driver matching from drivers/base/platform.c to arch/sh/drivers/platform_early.c. Also: call early_platform_cleanup() from subsys_initcall() so that it's called after all early devices are probed.

2011-06-14serial: sh-sci: Abstract register maps.Paul Mundt1-0/+5
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.

2009-08-13sh: convert processor device setup functions to arch_initcall()Magnus Damm1-1/+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().

2008-05-08sh: unify external irq pin code for sh3Magnus Damm1-29/+2

2008-02-26serial: Move asm-sh/sci.h to linux/serial_sci.h.Paul Mundt1-1/+1
This header is needed on other architectures as well (namely h8300), which currently fails to build without this in place. Rather than duplicating the port definition completely there, just move this to a common location instead. This should get h8300 working again for 2.6.25, in addition to the changes already pushed by Sato-san in -rc2. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-01-28sh: intc - remove default interrupt priority tablesMagnus Damm1-12/+2
This patch removes interrupt priority tables from the intc code. Optimal priority assignment varies with embedded application anyway, so keeping the interrupt priority tables together with cpu-specific code doesn't make sense. The function intc_set_priority() should be used instead to set the desired interrupt priority level. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
