      dt-bindings: power: sbs-battery: re-document "ti,bq20z75" · 45fab2c6
      Brian Norris authored
      This compatible property was documented before the driver was renamed to
      "SBS" (see commit e57f1b68 ("devicetree-bindings: Propagate
      bq20z75->sbs rename to dt bindings")). The driver has continued to
      support this property as an alternative to "sbs,sbs-battery", and
      because we've noticed there are some lingering TI specifics (in the
      manufacturer-specific portion of the SBS spec), we'd like to start using
      this property again to differentiate.
      
      In typical DT fashion, the <vendor>,<part-number> specifics should be
      used ahead of the generic "sbs,sbs-battery" string, so we can handle
      vendor specifics -- so document this. Language borrowed mostly from
      Documentation/devicetree/bindings/power/supply/sbs_sbs-charger.txt
      
      Also fixup the example to use this property (it's already implying that
      it's "bq20z75@b"); fixup the node name to be generic ("battery", not
      "<part-number>"); and fixup some whitespace.

      power: supply: sbs-battery: don't assume MANUFACTURER_DATA formats · 76b16f4c
      Brian Norris authored
      This driver was originally submitted for the TI BQ20Z75 battery IC
      (commit a7640bfa ("power_supply: Add driver for TI BQ20Z75 gas gauge
      IC")) and later renamed to express generic SBS support. While it's
      mostly true that this driver implemented a standard SBS command set, it
      takes liberties with the REG_MANUFACTURER_DATA register. This register
      is specified in the SBS spec, but it doesn't make any mention of what
      its actual contents are.
      
      We've sort of noticed this optionality previously, with commit
      17c6d397 ("sbs-battery: make writes to ManufacturerAccess
      optional"), where we found that some batteries NAK writes to this
      register.
      
      What this really means is that so far, we've just been lucky that most
      batteries have either been compatible with the TI chip, or else at least
      haven't reported highly-unexpected values.
      
      For instance, one battery I have here seems to report either 0x0000 or
      0x0100 to the MANUFACTURER_ACCESS_STATUS command -- while this seems to
      match either Wake Up (bits[11:8] = 0000b) or Normal Discharge
      (bits[11:8] = 0001b) status for the TI part [1], they don't seem to
      actually correspond to real states (for instance, I never see 0101b =
      Charge, even when charging).
      
      On other batteries, I'm getting apparently random data in return, which
      means that occasionally, we interpret this as "battery not present" or
      "battery is not healthy".
      
      All in all, it seems to be a really bad idea to make assumptions about
      REG_MANUFACTURER_DATA, unless we already know what battery we're using.
      Therefore, this patch reimplements the "present" and "health" checks to
      the following on most SBS batteries:
      
      1. HEALTH: report "unknown" -- I couldn't find a standard SBS command
         that gives us much useful here
      2. PRESENT: just send a REG_STATUS command; if it succeeds, then the
         battery is present
      
      Also, we stop sending MANUFACTURER_ACCESS_SLEEP to non-TI parts. I have
      no proof that this is useful and supported.
      
      If someone explicitly provided a 'ti,bq20z75' compatible property, then
      we continue to use the existing TI command behaviors, and we effectively
      revert commit 17c6d397 ("sbs-battery: make writes to
      ManufacturerAccess optional") to again make these commands required.
