Subject: [PATCH v2 0/2] arm64: dts: r8a779[56]: update register size for thermal
Date: Fri, 5 Jan 2018 16:54:45 +0100 [thread overview]
Message-ID: <20180105155447.10071-1-niklas.soderlund+renesas@ragnatech.se> (raw)
Hi,
This series updates the register size for the thermal hardware. In later
versions of the datasheet one additional register is documented. This
register is needed to be able to determine if calibration data should be
read from register or if static values from the driver should be used.
There is already a posted RFC patch which make use of this additional
register (THSCP) if the register size described in DT covers it.
Currently no hardware where the calibration value is fused have been
found so that patch is not tested and therefore kept back until such a
system is found. In the mean time there is no harm in getting the
correct register size described in DT now that it's documented in the
datasheet (Rev 0.80).
* Changes since v1
- Increase size from just covering the new register in TSC1 to
increasing the size of all TSC's to 0x100 which is the smallest
granularity of the address decoder circuitry. Suggested by Geert.
