From 421eda108e6c63a72feb178c441bb769d4076836 Mon Sep 17 00:00:00 2001 From: Guillaume La Roque Date: Fri, 4 Oct 2019 11:01:09 +0200 Subject: thermal: amlogic: Add thermal driver to support G12 SoCs Amlogic G12A and G12B SoCs integrate two thermal sensors with the same design. One is located close to the DDR controller and the other one is located close to the PLLs (between the CPU and GPU). The calibration data for each of the thermal sensors instance is stored in a different location within the AO region. Implement reading the temperature from each thermal sensor. The IP block has more functionality, which may be added to this driver in the future: - chip reset when the temperature exceeds a configurable threshold - up to four interrupts when the temperature has risen above a configurable threshold - up to four interrupts when the temperature has fallen below a configurable threshold Tested-by: Christian Hewitt Tested-by: Kevin Hilman Reviewed-by: Amit Kucheria Signed-off-by: Guillaume La Roque Signed-off-by: Daniel Lezcano Link: https://lore.kernel.org/r/20191004090114.30694-3-glaroque@baylibre.com --- drivers/thermal/Kconfig | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'drivers/thermal/Kconfig') diff --git a/drivers/thermal/Kconfig b/drivers/thermal/Kconfig index 001a21abcc28..129b9ed1d952 100644 --- a/drivers/thermal/Kconfig +++ b/drivers/thermal/Kconfig @@ -348,6 +348,17 @@ config MTK_THERMAL Enable this option if you want to have support for thermal management controller present in Mediatek SoCs +config AMLOGIC_THERMAL + tristate "Amlogic Thermal Support" + default ARCH_MESON + depends on OF && ARCH_MESON + help + If you say yes here you get support for Amlogic Thermal + for G12 SoC Family. + + This driver can also be built as a module.
