Hi,
On top of previous pull request.
Best regards,
Krzysztof
The following changes since commit 97d4b55111efd72926eb92cbd81c5ad8e6a7b3b1:
MAINTAINERS: Remove Tomasz from Samsung clock and pinctrl entries (2024-02-07 16:35:26 +0100)
are available in the Git repository at:
https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux.git tags/samsung-drivers-6.9-2

watchdog: s3c2410_wdt: use exynos_get_pmu_regmap_by_phandle() for PMU regs (2024-02-25 11:39:25 +0100)
----------------------------------------------------------------
Samsung SoC driver changes for v6.9, part two
1. Extend Exynos PMU (Power Management Unit) driver being also the
syscon to main system controller registers block, to support Google
GS101. The Google GS101 has PMU registers protected and writing is
available only via SMC. The Exynos PMU will register its own custom
regmap for such case of mixed MMIO+SMC.
2. Rework Samsung watchdog driver to get the regmap to PMU block not
via syscon API, but from the Exynos PMU driver. This is necessary
for the watchdog driver to work on Google GS101.
----------------------------------------------------------------

The last 4 MiB of RAM on those devices is likely used by trustzone
firmware, and is unusable under Linux. Change the device tree memory
node accordingly.
The proprietary bootloader (S-BOOT) passes these memory ranges through
ATAG_MEM; this change allows us to have the correct memory ranges
without relying on ATAG_MEM.
