2020-05-13hwmon: (da9052) Synchronize access with mfdSamu Nuutamo1-2/+2
When tsi-as-adc is configured it is possible for in7[0123]_input read to return an incorrect value if a concurrent read to in[456]_input is performed. This is caused by a concurrent manipulation of the mux channel without proper locking as hwmon and mfd use different locks for synchronization. Switch hwmon to use the same lock as mfd when accessing the TSI channel.

2018-12-16hwmon: (da9052-hwmon) Use permission specific SENSOR[_DEVICE]_ATTR variantsGuenter Roeck1-66/+39
Use SENSOR[_DEVICE]_ATTR[_2]_{RO,RW,WO} to simplify the source code, to improve readbility, and to reduce the chance of inconsistencies. Also replace any remaining S_<PERMS> in the driver with octal values. The conversion was done automatically with coccinelle. The semantic patches and the scripts used to generate this commit log are available at https://github.com/groeck/coccinelle-patches/hwmon/. This patch does not introduce functional changes. It was verified by compiling the old and new files and comparing text and data sizes.

2017-10-21hwmon: (da9052) Increase sample rate when using TSIMartyn Welch1-0/+5
The TSI channel, which is usually used for touchscreen support, but can be used as 4 general purpose ADCs. When used as a touchscreen interface the touchscreen driver switches the device into 1ms sampling mode (rather than the default 10ms economy mode) as recommended by the manufacturer. When using the TSI channels as a general purpose ADC we are currently not doing this and testing suggests that this can result in ADC timeouts: [ 5827.198289] da9052 spi2.0: timeout waiting for ADC conversion interrupt [ 5827.728293] da9052 spi2.0: timeout waiting for ADC conversion interrupt [ 5993.808335] da9052 spi2.0: timeout waiting for ADC conversion interrupt [ 5994.328441] da9052 spi2.0: timeout waiting for ADC conversion interrupt [ 5994.848291] da9052 spi2.0: timeout waiting for ADC conversion interrupt Switching to the 1ms timing resolves this issue.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core updates from Greg Kroah-Hartman: "Here's the large driver core updates for 3.8-rc1. The biggest thing here is the various __dev* marking removals. This is going to be a pain for the merge with different subsystem trees, I know, but all of the patches included here have been ACKed by their various subsystem maintainers, as they wanted them to go through here. If this is too much of a pain, I can pull all of them out of this tree and just send you one with the other fixes/updates and then, after 3.8-rc1 is out, do the rest of the removals to ensure we catch them all, it's up to you. The merges should all be trivial, and Stephen has been doing them all in linux-next for a few weeks now quite easily. Other than the __dev* marking removals, there's nothing major here, some firmware loading updates and other minor things in the driver core. All of these have (much to Stephen's annoyance), been in linux-next for a while.
