From: Patrice Chotard <patrice.chotard@st.com>
ST have sent patches which remove clock support for these SoCs [1]
which once applied mean the platform will no longer boot.
This series cleans up remaining STi drivers which have
support for these SoC's, by removing code, and updating the DT
documentation accordingly. Some drivers such as st_thermal_syscfg
can be removed completely because the IP is only found on these
legacy SoC's.
Patrice Chotard (5):
thermal: st_thermal_syscfg: Remove obsolete STiH415/416 platform
support.
ARM: multi_v7_defconfig: Remove ST_THERMAL_SYSCFG Kconfig symbol
ARM: multi_v7_defconfig: Remove CONFIG_ST_THERMAL_MEMMAP Kconfig
symbol
irqchip: st: remove STiH415/416 irqchip support

This Kconfig symbol is still used for the stih407 family thermal parts in drivers/thermal/st/st_thermal_memmap.c? My patch only removed the stih415/6 parts from the driver. regards, Peter.

STiH415/6 SoC support is being removed from the kernel.
This patch removes support from the syscfg thermal driver.
This driver also supports STiD127 SoC which has never been
upstreamed.
