* drivers: move the early platform device support to arch/shBartosz Golaszewski2019-10-071-0/+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.

* sh: Don't set the sh-sci platform data scscr CKE0 bitLaurent Pinchart2017-01-191-1/+1
| | | | | | | | | | The bit is only set by platforms that also set the CKE1 but, in which case its value is ignored by the device. Don't set it, this simplifies platform data and only leaves the CKE1 bit to be handled.

* sh: Don't set sh-sci pdata scscr TIE and RIE bitsLaurent Pinchart2017-01-191-2/+1
| | | | | | | | | | | | | | | | | | | | | | The scscr platform data field is used by the driver in three locations. One of them masks out all bits except SCSCR_REIE. The two other are the set_termios handler and the console write handler. The set_termios handler calls sci_start_rx() to enable the receiver, which sets the RIE bit unconditionally. It then calls sci_port_disable() that effectively disables both the transmitter and the receiver. The TIE bit will thus get set later when the serial cores reenables the serial port. The console write handler runs with interrupts disabled, and saves and restores the SCSCR register value. The RIE and TIE bits are thus not needed there. The bits are thus not necessary in platform data, remove them.

* serial: sh-sci: Abstract register maps.Paul Mundt2011-06-141-0/+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.

| | | | | | | | | | | | | | All SH-4 parts have a 4-digit year, while the SH-3 parts typically only use a 2-digit one. The SH7705, SH7710, and SH7712 SH-3 parts however opted to extend it to 4-digit and still look and act like an SH-3 RTC in all other ways. This adds a capability flag (RTC_CAP_4_DIGIT_YEAR) that these corner-case CPU subtypes can set in their platform data and cleans up some of the ifdef mess in the driver as a result.

* sh: rework ipr codeMagnus Damm2007-06-151-18/+22
| | | | | | | | | | | | | | | | | 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.
