Subject: [PATCH v9 0/4] thermal: renesas: Add support for RZ/G3E

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
