2021-07-06dm: define LOG_CATEGORY for all uclassPatrick Delaunay1-0/+2
Define LOG_CATEGORY for all uclass to allow filtering with log command. Signed-off-by: Patrick Delaunay <patrick.delaunay@foss.st.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2021-05-13w1: replace dt detection by automatic detectionKory Maincent1-2/+74
This patch changes the functioning of the detection of w1 devices. The old way was a comparison between detected w1 and the ones described in the device tree. Now it will just look for the driver matching the family id of the w1 detected. The patch is inspired from Maxime Ripard code.

2020-12-14dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass1-3/+3
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass1-2/+2
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-12-07w1: fix occasional enumeration failureMartin Fuzzey1-4/+0
Sometimes enumeration fails (about 1 in 50 times on my custom board). The underlying reason is probably electrical but Linux does not have the problem. Comparing the Linux / u-boot implementations shows that Linux retries the error case whereas u-boot aborts early. Removing the early abort in u-boot fixes the problem.

2018-11-01w1: fix data abort if no one wire bus master presentMartin Fuzzey1-6/+8
When the "w1 bus" command is used with no bus master present a data abort may occur. This is because uclass_first_device() returns zero, but sets the output struct udevice pointer to NULL in the no device found case. Fix w1_get_bus() to account for this and return an error code as is expected by the callers.

2018-09-29w1: identify devices with w1-eeprom uclassEugen Hristev1-0/+4
When a new device is discovered, this may be a w1 eeprom device. Attempt to find the proper node and driver from the w1-eeprom subsystem. Signed-off-by: Eugen Hristev <eugen.hristev@microchip.com>
2018-09-29w1: Add 1-Wire uclassMaxime Ripard1-0/+236
We might want to use 1-Wire devices connected on boards such as EEPROMs in U-Boot. Provide a framework to be able to do that. Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com> [eugen.hristev@microchip.com: reworked] Signed-off-by: Eugen Hristev <eugen.hristev@microchip.com>
