2021-10-21mfd: ti_am335x_tscadc: Clarify the maximum values for DT entriesMiquel Raynal
Clearly define the maximum open delay and sample delay. Use these definitions in place of a mask (which works because this is the first field in the register) and an open-coded value. While at it reword a little bit the error messages to make them look clearer and similar.

2021-10-20mfd: ti_am335x_tscadc: Use BIT(), GENMASK() and FIELD_PREP() when relevantMiquel Raynal
Clean the ti_am335x_tscadc.h header by: * converting masks to GENMASK() * converting regular shifts to BIT() * using FIELD_PREP() when relevant Sometimes reorder the lines to be able to use the relevant bitmask. Mind the s/%d/%ld/ change in a log due to the type change following the use of FIELD_PREP() in the header.

2021-10-20mfd: ti_am335x_tscadc: Gather the ctrl register logic in one placeMiquel Raynal
Instead of deriving in the probe and in the resume path the value of the ctrl register, let's do it only once in the probe, save the value of this register (all but the subsystem enable bit) in the driver's structure and use it from the resume callback.

2021-10-20mfd: ti_am335x_tscadc: Reorder the initialization stepsMiquel Raynal
TI AM335X TRM [1] states that most of the configuration should be set in the control register in the first place, before actually enabling the hardware with the subsystem enable bit. So far only half of the configuration was made in the first step (before enabling the "subsystem"), which does not make really sense. Also, the probe and the resume patch were acting differently. Let's harmonize all this by following these steps: 1/ Configure the CLKDIV register 2/ Configure the CTRL register 3/ Configure the idle configuration 4/ Really enable the device by rewriting the CTRL register with the subsystem enable bit set.

2021-10-08regulator: s5m8767: do not use reset value as DVS voltage if GPIO DVS is ↵Krzysztof Kozlowski
disabled The driver and its bindings, before commit 04f9f068a619 ("regulator: s5m8767: Modify parsing method of the voltage table of buck2/3/4") were requiring to provide at least one safe/default voltage for DVS registers if DVS GPIO is not being enabled. IOW, if s5m8767,pmic-buck2-uses-gpio-dvs is missing, the s5m8767,pmic-buck2-dvs-voltage should still be present and contain one voltage. This requirement was coming from driver behavior matching this condition (none of DVS GPIO is enabled): it was always initializing the DVS selector pins to 0 and keeping the DVS enable setting at reset value (enabled). Therefore if none of DVS GPIO is enabled in devicetree, driver was configuring the first DVS voltage for buck[234]. Mentioned commit 04f9f068a619 ("regulator: s5m8767: Modify parsing method of the voltage table of buck2/3/4") broke it because DVS voltage won't be parsed from devicetree if DVS GPIO is not enabled. After the change, driver will configure bucks to use the register reset value as voltage which might have unpleasant effects. Fix this by relaxing the bindings constrain: if DVS GPIO is not enabled in devicetree (therefore DVS voltage is also not parsed), explicitly disable it.

It resolves a build issue that many people were hitting with your current tree, and Kees and others felt would be good to get merged before -rc1 comes out, to prevent them from having to constantly hit it as many development trees restart on -rc1, not older -rc releases. It has NOT been in linux-next, but has passed 0-day testing and looks 'obviously correct' when reviewing it locally :)" * tag 'char-misc-5.15-rc1-lkdtm' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: lkdtm: Use init_uts_ns.name instead of macros
