2021-10-25	irqchip/mchp-eic: Fix return value check in mchp_eic_init()	Yang Yingliang	1	-1/+1
	In case of error, the function of_iomap() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.

2021-10-20	irqchip/mchp-eic: Add support for the Microchip EIC	Claudiu Beznea	1	-0/+280
	Add support for Microchip External Interrupt Controller. The controller supports 2 external interrupt lines. For every external input there is a connection to GIC. The interrupt controllers contains only 4 registers: - EIC_GFCS (read only): which indicates that glitch filter configuration is ready (not addressed in this implementation) - EIC_SCFG0R, EIC_SCFG1R (read, write): allows per interrupt specific settings: enable, polarity/edge settings, glitch filter settings - EIC_WPMR, EIC_WPSR: enables write protection mode specific settings (which are architecture specific) for the controller and are not addressed in this implementation Signed-off-by: Claudiu Beznea <claudiu.beznea@microchip.com> Signed-off-by: Marc Zyngier <maz@kernel.org> Link: https://lore.kernel.org/r/20210927063657.2157676-3-claudiu.beznea@microchip.com
