+Subject: [PATCH 123/148] leds-gpio: Implement the brightness_get method
+
+The power LED uses some clever logic that means it is driven
+by a voltage measuring circuit when configured as input, otherwise
+it is driven by the GPIO output value. This patch wires up the
+brightness_get method for leds-gpio so that user-space can monitor
+the LED value via /sys/class/gpio/led1/brightness. Using the input
+trigger this returns an indication of the system power health,
+otherwise it is just whatever value the trigger has written most
+recently.
+
+See: https://github.com/raspberrypi/linux/issues/1064

+This reverts commit 40aa3c4f0c430cd5c574498f4d1d5e9f0bc1cf11.
+
+The legacy mailbox API has been removed so this is not needed.

+Subject: [PATCH 148/148] pinctrl: bcm2835: Clear the event latch register when
+ disabling interrupts
+
+It's possible to hit a race condition if interrupts are generated on a GPIO
+pin when the IRQ line in question is being disabled.
+
+If the interrupt is freed, bcm2835_gpio_irq_disable() is called which
+disables the event generation sources (edge, level). If an event occurred
+between the last disabling of hard IRQs and the write to the event
+source registers, a bit would be set in the GPIO event detect register
+(GPEDSn) which goes unacknowledged by bcm2835_gpio_irq_handler()
+so Linux complains loudly.
+
+There is no per-GPIO mask register, so when disabling GPIO interrupts
+write 1 to the relevant bit in GPEDSn to clear out any stale events.
