drivers: thermal: tsens: Don't print error message on -EPROBE_DEFER

2019-06-15T09:52:53Z

[ Upstream commit fc7d18cf6a923cde7f5e7ba2c1105bb106d3e29a ] We print a calibration failure message on -EPROBE_DEFER from nvmem/qfprom as follows: [ 3.003090] qcom-tsens 4a9000.thermal-sensor: version: 1.4 [ 3.005376] qcom-tsens 4a9000.thermal-sensor: tsens calibration failed [ 3.113248] qcom-tsens 4a9000.thermal-sensor: version: 1.4 This confuses people when, in fact, calibration succeeds later when nvmem/qfprom device is available. Don't print this message on a -EPROBE_DEFER. Signed-off-by: Amit Kucheria Signed-off-by: Eduardo Valentin Signed-off-by: Sasha Levin

thermal/qcom/tsens-common : fix possible object reference leak

of_find_device_by_node() takes a reference to the struct device when it finds a match via get_device. We also should make sure to drop the reference to the device taken by of_find_device_by_node() when returning error. Signed-off-by: Peng Hao Signed-off-by: Eduardo Valentin

thermal: tsens: qcom: do not create duplicate regmap debugfs entries

2019-01-02T12:47:11Z

Regmap would use device name to create debugfs entries. If the device has multiple regmaps it is recommended to use name field in regmap_config. Fix this by providing name to the regmap configs correctly. Without this patch we would see below error on DB820c. qcom-tsens 4a9000.thermal-sensor: Failed to create 4a9000.thermal-sensor debugfs directory Signed-off-by: Srinivas Kandagatla Acked-by: Amit Kucheria Tested-by: Amit Kucheria Signed-off-by: Eduardo Valentin

drivers: thermal: Move QCOM_SPMI_TEMP_ALARM into the qcom subdir

2018-12-07T08:49:02Z

This cleans up the directory a bit allowing just one place to look for thermal related drivers for QCOM platforms instead of being scattered in the root directory and the qcom/ subdirectory. Compile-tested with ARCH=arm64 defconfig and the driver explicitly enabled with menuconfig. Signed-off-by: Amit Kucheria Acked-by: Daniel Lezcano Signed-off-by: Zhang Rui

thermal: tsens: Check if the IP is correctly enabled by firmware

The SROT registers are initialised by the secure firmware at boot. We don't have write access to the registers. Check if the block is enabled before continuing. Signed-off-by: Amit Kucheria Reviewed-by: Bjorn Andersson Signed-off-by: Eduardo Valentin

thermal: tsens: Pass register offsets as private data

2018-10-23T00:34:33Z

Registers have moved around across TSENS generations. For example, the CTRL register was at offset 0x0 in the SROT region on msm8916 but is at offset 0x4 in newer v2 based TSENS HW blocks. Allow passing offsets of important registers so that we can continue to use common functions. Signed-off-by: Amit Kucheria Reviewed-by: Bjorn Andersson Signed-off-by: Eduardo Valentin

thermal: tsens: Add the SROT address map

2018-10-23T00:33:48Z

On platforms whose device trees specify two address spaces for TSENS, the second one points to the SROT registers. Initialise the SROT map on those platforms. Signed-off-by: Amit Kucheria Reviewed-by: Matthias Kaehlcke Reviewed-by: Bjorn Andersson Signed-off-by: Eduardo Valentin

thermal: tsens: Rename map field in order to add a second address map

2018-10-23T00:33:23Z

The TSENS driver currently only uses a limited set of registers from the TM address space. So it was ok to map just that set of registers and call it "map". We'd now like to map a second set: SROT registers to introduce new functionality. Rename the "map" field to a more appropriate "tm_map". The 8960 doesn't have a clear split between TM and SROT registers. To avoid complicating the data structure, it will switchover to using tm_map for its maps. There is no functional change with this patch. Signed-off-by: Amit Kucheria Reviewed-by: Matthias Kaehlcke Reviewed-by: Bjorn Andersson Signed-off-by: Eduardo Valentin
