clocksource/drivers/vf-pit: Replace raw_readl/writel to readl/writel
[ Upstream commit 0b781f527d6f99e68e5b3780ae03cd69a7cb5c0c ] The driver uses the raw_readl() and raw_writel() functions. Those are not for MMIO devices. Replace them with readl() and writel() [ dlezcano: Fixed typo in the subject s/reald/readl/ ] Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Acked-by: Arnd Bergmann <arnd@arndb.de> Cc: Arnd Bergmann <arnd@arndb.de> Link: https://lore.kernel.org/r/20250804152344.1109310-2-daniel.lezcano@linaro.org Signed-off-by: Sasha Levin <sashal@kernel.org>
