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.

Since the commit 888cc8c20cf ("sh_eth: remove EDMAC_BIG_ENDIAN") (geez, I didn't realize that was 2 years ago!) the initializers in the SuperH platform code for the 'sh_eth_plat_data::edmac_endian' stopped to matter, so we can remove that field for good (not sure if it was ever useful -- SH7786 Ether has been reported to have the same EDMAC descriptor/register endiannes as configured for the SuperH CPU)...

Commit 06a64f91da72cb5827e2bedef2ead60a123fd66e (SH7619: fix Ether support) has a typo in the 'phy_interface' field name of the platform data which causes build error -- fix it. Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Now that the 'register_type' field of the 'sh_eth' driver's platform data is not used by the driver anymore, it's time to remove it and its initializers from the SH platform code. Also move *enum* declaring values for this field from <linux/sh_eth.h> to the local driver's header file as they're only needed by the driver itself now...

2013-08-20SH7619: fix Ether supportSergei Shtylyov1-2/+10
The 'sh_eth' driver's probe will crash as the platform code is hopelessly behind the platform data -- it passes PHY ID instead of 'struct sh_eth_plat_data *'. Strangely, both commit d88a3ea6fa4c (SH7619 add ethernet controler support) that added the platform code and commit 71557a37adb5 ([netdrvr] sh_eth: Add SH7619 support) were done in about the same time, yet the latter one added 'struct sh_eth_plat_data' and the platform code didn't ever get updated...

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().

2008-02-26serial: 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 Damm1-1/+1
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>

2007-07-20sh: IPR/INTC2 IRQ setup consolidation.Magnus Damm1-1/+1
This patch unifies the cpu specific interrupt setup functions for interrupt controller blocks such as ipr, intc2 and intc. There is no point in having separate functions for each interrupt controller, so let's clean this up. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-15sh: rework ipr codeMagnus Damm1-10/+14
This patch reworks the ipr code by grouping the offset array together with the ipr_data structure in a new data structure called ipr_desc. This new structure also contains the name of the controller in struct irq_chip. The idea behind putting struct irq_chip in there is that we can use offsetof() to locate the base addresses in the irq_chip callbacks. This strategy has much in common with the recently merged intc2 code. One logic change has been made - the original ipr code enabled the interrupts by default but with this patch they are all disabled by default.
