Subject: [GIT PULL] samsung: drivers firmware for v7.2 (also for thermal)
Date: Sun, 31 May 2026 13:57:13 +0200 [thread overview]
Message-ID: <20260531115713.19388-2-krzk@kernel.org> (raw)
Hi Arnd and SoC folks, and Rafael+Daniel+Zhang+Lukasz,
This is pull with firmware drivers built on top of my previous firmware fixes:
tags/samsung-drivers-fixes-7.1-2.
The code here will be also necessary for thermal tree for implementing actual
TMU driver.
Best regards,
Krzysztof
