Subject: [PATCH v9 0/4] thermal: renesas: Add support for RZ/G3E
Date: Wed, 17 Sep 2025 19:01:54 +0200 [thread overview]
Message-ID: <20250917170202.197929-1-john.madieu.xa@bp.renesas.com> (raw)
This series adds support for the temperature sensor unit (TSU) found on the
Renesas RZ/G3E SoC.
The initial syscon patch [1] the series depends on has already been accepted.
Changes:
v9:
* Remove driver-specific read/write indirection and use readl/writel
* Use devm_mutex_init()
* Switch to syscon_regmap_lookup_by_phandle_args()
v8:
* Use of_parse_phandle_with_fixed_args() for trim values
* Update binding doc and collect Rb tag from Rob
* Use millidegree computation to for better precision
v6 -> v7
* Update DTS trim priperty name and specifier, updading the documentation
accordingly
* Refactor main driver: remove spinlock usage, using polling timeout as computed
from datasheet. Also use polling for get_temp() while using IRQ for trip-point
cross detection, and finally add both runtime and sleep PM support.
* Add new patch to update sys #address-cells as trim specifier now requires an
offset from sys base
v5 -> v6
* Minor typo fix
* Constify regmap config in patch 1/5
v4 -> v5
* Remove useless curly braces on single line-protected scoped guards
v3 -> v4
* Improve commit messages
v2 -> v3
* Remove useless 'renesas,tsu-operating-mode' property
v1 -> v2
* Fix yaml warnings from dt-binding
* Update IRQ names to reflect TSU expectations
