* Add locking to the various iicbus(4) bridge drivers:John Baldwin2008-08-045-34/+82
| | | | | | | | | | | | | | | | | | | | | | | | - Just grab Giant in the ixp425_iic(4) driver since this driver uses a shared address/data register window pair to access the actual I2C registers. None of the other ixp425 drivers lock access to these shared address/data registers yet and that would need to be done before this could use any meaningful locking. - Add locking to the interrupt handler and 'iicbus_reset' methods of the at91_twi(4) driver. - Add locking to the pcf(4) driver. Other pcf(4) fixes include: - Don't needlessly zero the softc. - Use bus_foo rather than bus_space_foo and remove bus space tag and handle from softc. - The lpbb(4) driver just grabs Giant for now. This will be refined later when ppbus(4) is locked. - As was done with smbus earlier, move the DRIVER_MODULE() lines to match the bus driver (either iicbus or iicbb) to the bridge driver into the bridge drivers.

| | | | | | | | | | | | | interrupt handlers rather than BUS_SETUP_INTR() and BUS_TEARDOWN_INTR(). Uses of the BUS_*() versions in the implementation of foo_intr methods in bus drivers were not changed. Mostly this just means that some drivers might start printing diagnostic messages like [FAST] when appropriate as well as honoring mpsafenet=0. - Fix two more of the ppbus drivers' identify routines to function correctly in the mythical case of a machine with more than one ppbus.

* - Introduce an ofw_bus kobj-interface for retrieving the OFW node and aMarius Strobl2004-08-122-13/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | subset ("compatible", "device_type", "model" and "name") of the standard properties in drivers for devices on Open Firmware supported busses. The standard properties "reg", "interrupts" und "address" are not covered by this interface because they are only of interest in the respective bridge code. There's a remaining standard property "status" which is unclear how to support properly but which also isn't used in FreeBSD at present. This ofw_bus kobj-interface allows to replace the various (ebus_get_node(), ofw_pci_get_node(), etc.) and partially inconsistent (central_get_type() vs. sbus_get_device_type(), etc.) existing IVAR ones with a common one. This in turn allows to simplify and remove code-duplication in drivers for devices that can hang off of more than one OFW supported bus. - Convert the sparc64 Central, EBus, FHC, PCI and SBus bus drivers and the drivers for their children to use the ofw_bus kobj-interface. The IVAR- interfaces of the Central, EBus and FHC are entirely replaced by this. The PCI bus driver used its own kobj-interface and now also uses the ofw_bus one. The IVARs special to the SBus, e.g. for retrieving the burst size, remain. Beware: this causes an ABI-breakage for modules of drivers which used the IVAR-interfaces, i.e. esp(4), hme(4), isp(4) and uart(4), which need to be recompiled. The style-inconsistencies introduced in some of the bus drivers will be fixed by tmm@ in a generic clean-up of the respective drivers later (he requested to add the changes in the "new" style). - Convert the powerpc MacIO bus driver and the drivers for its children to use the ofw_bus kobj-interface. This invloves removing the IVARs related to the "reg" property which were unused and a leftover from the NetBSD origini of the code. There's no ABI-breakage caused by this because none of these driver are currently built as modules. There are other powerpc bus drivers which can be converted to the ofw_bus kobj-interface, e.g. the PCI bus driver, which should be done together with converting powerpc to use the OFW PCI code from sparc64. - Make the SBus and FHC front-end of zs(4) and the sparc64 eeprom(4) take advantage of the ofw_bus kobj-interface and simplify them a bit.

* Add a first version of a pcf(4) front-end for the Sun i2c devices ("i2c"Marius Strobl2004-06-101-0/+261
| | | | | | | | | | | | | | | | | | | | | | is the actual name here) on EBus and which are PCF8584 (on systems having a boot-bus controller the i2c are said to not be a PCF8584). Similar to the SUNW,envctrl devices, onboard slaves for monitoring fans, temperatures and such hang off of these i2c devices. But there's also stuff like EEPROMs housing the hostid of the system and the boards usally have a connector to add custom slave devices (on CP1500 there's actually a second PCF8584 with its own I2C bus for these). This driver already works fine but I'm not yet sure if access to the slave devices on CP1400/CP1500 marked as "reserved for factory use" in the docs should be blocked (most likely these are the voltage controllers wich aren't meant to be controller by software and even not by the firmware). Once the issues with polled mode are fixed in the common pcf(4) part in pcf.c, this front-end should probably honour the poll-mode property of the i2c devices. Tested on Ultra AXe and CP1500 (Netra t1 100). OK'ed by: joerg, nsouch Notes: svn path=/head/; revision=130320

* Necessary modifications do get pcf working again for ISA. Tested withNicolas Souchu2004-05-312-15/+55
| | | | | | | | | | | | | my Elektor card. Note that the hints are necessary to specify the IO base of the pcf chip. This enables to check the IO base when the probe routine is called during ISA enumeration. The interrupt driven code is mixed with polled mode, which is wrong and produces supposed spurious interrupts at each access. I still have to work on it. Notes: svn path=/head/; revision=129893
* Round #1 of improving pcf(4).Joerg Wunsch2004-05-254-320/+645
| | | | | | | | | | | | | | | This splits the driver into a bus-independant backend, plus bus-specific frontends. The old pcf(4) (i386/ISA) frontend is now in pcf_isa.c, the frontend in envctrl.c is for sparc64/Ebus2 (Sun device name: SUNW,envctrl from Sun E450 machines). More frontends are expected to appear in future. This is not yet ready for public consumption, but it basically works. Nicolas will bring over his ISA-specific fixes soon.

* Port of ppbus standalone framework to the newbus system.Nicolas Souchu2000-01-141-76/+64
| | | | | | | | | | | | | | | | | | | | | | | | Note1: the correct interrupt level is invoked correctly for each driver. For this purpose, drivers request the bus before being able to call BUS_SETUP_INTR and BUS_TEARDOWN_INTR call is forced by the ppbus core when drivers release it. Thus, when BUS_SETUP_INTR is called at ppbus driver level, ppbus checks that the caller owns the bus and stores the interrupt handler cookie (in order to unregister it later). Printing is impossible while plip link is up is still TRUE. vpo (ZIP driver) and lpt are make in such a way that using the ZIP and printing concurrently is permitted is also TRUE. Note2: specific chipset detection is not done by default. PPC_PROBE_CHIPSET is now needed to force chipset detection. If set, the flags 0x40 still avoid detection at boot. Port of the pcf(4) driver to the newbus system (was previously directly connected to the rootbus and attached by a bogus pcf_isa_probe function). Notes: svn path=/head/; revision=55939
* Remove the 'ivars' arguement to device_add_child() andMatthew N. Dodd1999-12-031-1/+1
| | | | | | | | | | | | | | | | | | | device_add_child_ordered(). 'ivars' may now be set using the device_set_ivars() function. This makes it easier for us to change how arbitrary data structures are associated with a device_t. Eventually we won't be modifying device_t to add additional pointers for ivars, softc data etc. Despite my best efforts I've probably forgotten something so let me know if this breaks anything. I've been running with this change for months and its been quite involved actually isolating all the changes from the rest of the local changes in my tree.

* Alter the behavior of sys/kern/subr_bus.c:device_print_child()Matthew N. Dodd1999-07-291-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - device_print_child() either lets the BUS_PRINT_CHILD method produce the entire device announcement message or it prints "foo0: not found\n" Alter sys/kern/subr_bus.c:bus_generic_print_child() to take on the previous behavior of device_print_child() (printing the "foo0: <FooDevice 1.1>" bit of the announce message.) Provide bus_print_child_header() and bus_print_child_footer() to actually print the output for bus_generic_print_child(). These functions should be used whenever possible (unless you can just use bus_generic_print_child()) The BUS_PRINT_CHILD method now returns int instead of void. Modify everything else that defines or uses a BUS_PRINT_CHILD method to comply with the above changes. - Devices are 'on' a bus, not 'at' it. - If a custom BUS_PRINT_CHILD method does the same thing as bus_generic_print_child(), use bus_generic_print_child() - Use device_get_nameunit() instead of both device_get_name() and device_get_unit() - All BUS_PRINT_CHILD methods return the number of characters output.
