2008-10-08[MIPS] Sibyte: Register PIO PATA device only for Swarm and Litte SurRalf Baechle1-0/+4
Symbol name spaghetti which is too complicated to cleanup on this stage of the release cycle breaks the build on BCM1480 platforms. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-10-05IDE: Fix platform device registration in Swarm IDE driver (v2)Ralf Baechle2-1/+83
The Swarm IDE driver uses a release method which is defined in the driver itself thus potentially oopsable. The simple fix would be to just leak the device but this patch goes the full length and moves the entire handling of the platform device in the platform code and retains only the platform driver code in drivers/ide/mips/swarm.c.

2008-07-15i2c-sibyte: SWARM I2C board initializationMaciej W. Rozycki2-0/+38
The standard rtc-m41t80.c driver cannot be used with the SWARM as it is, because the board does not provide setup information for the I2C core. As a result the bus and the address to probe for the M41T80 chip is not known. Here is a set of changes that fix the problem: 1. swarm-i2c.c -- SWARM I2C board setup, currently for the M41T80 chip on the bus #1 only (there is a MAX6654 temperature sensor on the bus #0 which may be added in the future if we have a driver for that chip). 2. The i2c-sibyte.c BCM1250A SMBus controller driver now registers its buses as numbered so that board setup is correctly applied. Signed-off-by: Maciej W.

2007-10-29[MIPS] Sibyte: Delete {sb1250,bcm1480}_steal_irq().Ralf Baechle4-54/+0
They break the timer interrupt initialization and only seem to be a kludge for initialization happening in the wrong order. Further testing done by Thiemo confirms the suspicion that the other invocations also seem to have useless. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-10-23[MIPS] time: SMP-proofing of Sibyte clockevent/clocksource code.Ralf Baechle6-165/+158
The BCM148 has 4 cores but there are also just 4 generic timers available so use the ZBbus cycle counter instead of it. In addition the ZBbus counter also offers a much higher resolution and 64-bit counting so I'm considering a later complete conversion to it once I figure out if all members of the Sibyte SOC family support it - the docs seem to agree but the headers files seem to disagree ...

2007-10-12[MIPS] Switch from to_tm to rtc_time_to_tmRalf Baechle2-2/+4
This replaces the MIPS-specific to_tm function with the generic rtc_time_to_tm function. The big difference between the two functions is that rtc_time_to_tm uses epoch 70 while to_tm uses 1970, so the result of rtc_time_to_tm needs to be fixed up. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-07-17sb1250-duart.c: SB1250 DUART serial supportMaciej W. Rozycki2-0/+2
This is a driver for the SB1250 DUART, a dual serial port implementation included in the Broadcom family of SOCs descending from the SiByte SB1250 MIPS64 chip multiprocessor. It is a new implementation replacing the old-fashioned driver currently present in the linux-mips.org tree. It supports all the usual features one would expect from a(n asynchronous) serial driver, including modem line control (as far as hardware supports it -- there is edge detection logic missing from the DCD and RI lines and the driver does not implement polling of these lines at the moment), the serial console, BREAK transmission and reception, including the magic SysRq. The receive FIFO threshold is not maintained though. The driver was tested with a SWARM board which uses a BCM1250 SOC (which is dual MIPS64 CMP) and has both ports of the single DUART implemented wired externally. Both were tested. Testing included using the ports as terminal lines at 1200bps (which is the ports minimum), 115200bps and a couple of random speeds inbetween. The modem lines were verified to operate correctly. No testing was performed with a use as a network interface, like with SLIP or PPP. Signed-off-by: Maciej W.
