[PATCH] thermal: Add Mediatek thermal support

This adds support for the Mediatek thermal controller found on MT8173 and likely other SoCs. The controller is a bit special. It does not have its own ADC, instead it controls the on-SoC AUXADC via AHB bus accesses. For this reason we need the physical address of the AUXADC. Also it controls a mux

[PATCH] parisc: mm: Fix a memory leak related to pmd not attached to the pgd

Commit 0e0da48dee8d ("parisc: mm: don't count preallocated pmds") introduced a memory leak. After this commit, the 'return' statement in pmd_free is executed in all cases. Even for pmd that are not attached to the pgd. So 'free_pages' can never be called anymore, leading to a memory leak.

[PATCH 1/5] clocksource: mediatek: do not enable GPT_CLK_EVT when setup

Spurious mtk timer interrupt is noticed at boot and cause kernel crash. It seems if GPT is enabled, it will latch irq status even when its IRQ is disabled. When irq is enabled afterward, we see spurious interrupt. Change init flow to only enable GPT_CLK_SRC at mtk_timer_init. Signed-off-by:
