* w1/ds2482: Convert to a new-style driverJean Delvare2008-07-161-60/+44
| | | | | | | | The new-style ds2482 driver implements the optional detect() callback to cover the use cases of the legacy driver. I'm curious if anyone really needs this though, so it might be removed in the feature. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* ds1wm: report bus reset errorAnton Vorontsov2008-03-041-9/+9
| | | | | | | | | | | | | | | The patch replaces dev_dbg() by dev_err(), so the user could actually see the error, instead of wondering why w1 doesn't work. The root cause of the bus reset error isn't yet debugged though, but this sometimes happens on iPaq H5555. And while I'm at it, some cosmetic cleanups also made (few lines were using spaces instead of tabs).

* ds1wm: should check for IS_ERR(clk) instead of NULLAnton Vorontsov2008-03-041-2/+3
| | | | | | | | | | | | | | On the error condition clk_get() returns ERR_PTR(..), so checking for NULL doesn't work. ds1wm module causes a kernel oops when ds1wm clock isn't registered. This patch converts NULL check to IS_ERR(), plus uses PTR_ERR() for the return code.

* DS1WM: decouple host IRQ and INTR active state settingsPhilipp Zabel2008-02-071-4/+5
| | | | | | | | | | | | | The DS1WM driver incorrectly infers the IAS bit (1-wire interrupt active high) from IRQ settings. There are devices that have IAS=0 but still need the IRQ to trigger on a rising edge. With this patch, machines with DS1WM that need IAS=1 have to set .active_high=1 in the ds1wm_platform_data.

* w1-gpio: add GPIO w1 bus master driverVille Syrjala2008-02-063-0/+135
| | | | | | | | | | | | Add a GPIO 1-wire bus master driver. The driver used the GPIO API to control the wire and the GPIO pin can be specified using platform data similar to i2c-gpio. The driver was tested with AT91SAM9260 + DS2401.

| | | | | | | | | | The idle check loop has a greater-than where it should have a less-than. This causes the ds2482 driver to check for the idle condition exactly once, which causes it to fail on faster machines.
