2015-11-03thermal: rockchip: support the sleep pinctrl state to avoid glitches in s2rCaesar Wang1-0/+4
When we come out of system suspend state (S3) the tsadc will have been reset and back at its default state. While reprogramming the tsadc it's possible that we'll glitch the output and unintentionally cause the "over temperature" GPIO to be asserted. Since the over temperature GPIO is often hooked up to something that will cause a reboot or shutdown in hardware, this glitch can be catastrophic on some boards. We'll add support for selecting the "sleep" pinctrl state at suspend time. Boards can use this to effectively disable the tsadc at suspend time and avoid glitches when the system is resumed.

We attempted to signal invalid code by returning -EAGAIN from rk_tsadcv2_code_to_temp(), unfortunately the return value was stuffed directly into the temperature pointer, potentially confusing upper layers with temperature of -EINVAL. Let's split temperature from error/success indicator to avoid such confusion. Also change the way we scan the temperature table to start with the 2nd element so that we do not need to worry that we may reference out of bounds element while doing binary search and keep checking that we end up with 'mid' equal to 0 (since we are looking for the temperature that would fall into interval between the 'mid' and 'mid - 1') .

I didn't notice this when merging the thermal code from Zhang, but his merge (commit 5a924a07f882: "Merge branches 'thermal-core' and 'thermal-intel' of .git into next") of the thermal-core and thermal-intel branches was wrong. In thermal-core, commit 17e8351a7739 ("thermal: consistently use int for temperatures") converted the thermal layer to use "int" for temperatures. But in parallel, in the thermal-intel branch commit d0a12625d2ff ("thermal: Add Intel PCH thermal driver") added support for the intel PCH thermal sensor using the old interfaces that used "unsigned long" pointers. This resulted in warnings like this: drivers/thermal/intel_pch_thermal.c:184:14: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types] .get_temp = pch_thermal_get_temp, ^ drivers/thermal/intel_pch_thermal.c:184:14: note: (near initialization for ‘tzd_ops.get_temp’) drivers/thermal/intel_pch_thermal.c:186:19: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types] .get_trip_temp = pch_get_trip_temp, ^ drivers/thermal/intel_pch_thermal.c:186:19: note: (near initialization for ‘tzd_ops.get_trip_temp’) This fixes it.

git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux Pull thermal updates from Zhang Rui: - use int instead of unsigned long to represent temperature to avoid bogus overheat detection when negative temperature reported. From Sascha Hauer. - export available thermal governors information to user space via sysfs. From Wei Ni. - introduce new thermal driver for Wildcat Point platform controller hub, which uses PCH thermal sensor and associated critical and hot trip points. From Tushar Dave. - add suuport for Intel Skylake and Denlow platforms in powerclamp driver. - some small cleanups in thermal core. * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: thermal: Add Intel PCH thermal driver thermal: Add comment explaining test for critical temperature thermal: Use IS_ENABLED instead of #ifdef thermal: remove unnecessary call to thermal_zone_device_set_polling thermal: trivial: fix typo in comment thermal: consistently use int for temperatures thermal: add available policies sysfs attribute thermal/powerclamp: add cpu id for denlow platform thermal/powerclamp: add cpu id for Skylake u/y thermal/powerclamp: add cpu id for skylake h/s

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap Pull regmap updates from Mark Brown: "This has been a busy release for regmap. By far the biggest set of changes here are those from Markus Pargmann which implement support for block transfers in smbus devices. This required quite a bit of refactoring but leaves us better able to handle odd restrictions that controllers may have and with better performance on smbus. Other new features include: - Fix interactions with lockdep for nested regmaps (eg, when a device using regmap is connected to a bus where the bus controller has a separate regmap). Lockdep's default class identification is too crude to work without help. - Support for must write bitfield operations, useful for operations which require writing a bit to trigger them from Kuniori Morimoto. - Support for delaying during register patch application from Nariman Poushin. - Support for overriding cache state via the debugfs implementation from Richard Fitzgerald" * tag 'regmap-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: (25 commits) regmap: fix a NULL pointer dereference in __regmap_init regmap: Support bulk reads for devices without raw formatting regmap-i2c: Add smbus i2c block support regmap: Add raw_write/read checks for max_raw_write/read sizes regmap: regmap max_raw_read/write getter functions regmap: Introduce max_raw_read/write for regmap_bulk_read/write regmap: Add missing comments about struct regmap_bus regmap: No multi_write support if bus->write does not exist regmap: Split use_single_rw internally into use_single_read/write regmap: Fix regmap_bulk_write for bus writes regmap: regmap_raw_read return error on !bus->read regulator: core: Print at debug level on debugfs creation failure regmap: Fix regmap_can_raw_write check regmap: fix typos in regmap.c regmap: Fix integertypes for register address and value regmap: Move documentation to regmap.h regmap: Use different lockdep class for each regmap init call thermal: sti: Add parentheses around bridge->ops->regmap_init call mfd: vexpress: Add parentheses around bridge->ops->regmap_init call regmap: debugfs: Fix misuse of IS_ENABLED ...
