* w1: add 1-wire master driver for IP block found in SGI ASICsThomas Bogendoerfer2019-09-043-0/+140
| | | | | | | | | | | | | | Starting with SGI Origin machines nearly every new SGI ASIC contains an 1-Wire master. They are used for attaching One-Wire prom devices, which contain information about part numbers, revision numbers, serial number etc. and MAC addresses for ethernet interfaces. This patch adds a master driver to support this IP block. It also adds an extra field dev_id to struct w1_bus_master, which could be in used in slave drivers for creating unique device names.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | >From the DS2408 datasheet [1]: "Resume Command function checks the status of the RC flag and, if it is set, directly transfers control to the control functions, similar to a Skip ROM command. The only way to set the RC flag is through successfully executing the Match ROM, Search ROM, Conditional Search ROM, or Overdrive-Match ROM command" The function currently works perfectly fine in a multidrop bus, but when we have only a single slave connected, then only a Skip ROM is used and Match ROM is not called at all. This is leading to problems e.g. with single one DS2408 connected, as the Resume Command is not working properly and the device is responding with failing results after the Resume Command. This commit is fixing this by using a Skip ROM instead in those cases. The bandwidth / performance advantage is exactly the same.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we have success in 'Channel Access Write' but reading back latch states fails, a write is retried without doing a proper slave reset. This leads to protocol errors as the slave treats the next 'Channel Access Write' as the continuation of previous command. This commit is fixing this by making sure if the retry loop re-runs, a reset is performed, whatever the failure (CONFIRM_BYTE or the read back). The loop was quite due for a cleanup and this change mandated it. By isolating the CONFIG_W1_SLAVE_DS2408_READBACK case into it's own function, we vastly reduce the visual and branching(runtime and compile-time) noise.

|/ | | | | | | | | | | | | | | | | | The syzkaller USB fuzzer spotted a slab-out-of-bounds bug in the ds2490 driver. This bug is caused by improper use of the altsetting array in the usb_interface structure (the array's entries are not always stored in numerical order), combined with a naive assumption that all interfaces probed by the driver will have the expected number of altsettings. The bug can be fixed by replacing references to the possibly non-existent intf->altsetting[alt] entry with the guaranteed-to-exist intf->cur_altsetting entry.

The old device name "ds2760-battery.0" is preserved, so userspace applications can access the same virtual device nodes as before.

| |/ | | | | | | | | | | | | | | | | | | | | The variable extra_config is local to the source and does not need to be in global scope, so make it static. Cleans up sparse warning: warning: symbol 'extra_config' was not declared. Should it be static?

* / w1: Allow compile test of GPIO consumers if !GPIOLIBGeert Uytterhoeven2018-06-261-1/+1
|/ | | | | | | | | | | | | | The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate.
