-Subject: [PATCH] irqchip: irq-bcm2836: Remove regmap and syscon use
-
-The syscon node defines a register range that duplicates that used by
-the local_intc node on bcm2836/7. Since irq-bcm2835 and irq-bcm2836 are
-built in and always present together (both drivers are enabled by
-CONFIG_ARCH_BCM2835), it is possible to replace the syscon usage with a
-global variable that simplifies the code. Doing so does lose the
-locking provided by regmap, but as only one side is using the regmap
-interface (irq-bcm2835 uses readl and write) there is no loss of
-atomicity.
