brcm2708: rename target to bcm27xx
This change makes the names of Broadcom targets consistent by using the common notation based on SoC/CPU ID (which is used internally anyway), bcmXXXX instead of brcmXXXX. This is even used for target TITLE in make menuconfig already, only the short target name used brcm so far. Despite, since subtargets range from bcm2708 to bcm2711, it seems appropriate to use bcm27xx instead of bcm2708 (again, as already done for BOARDNAME). This also renames the packages brcm2708-userland and brcm2708-gpu-fw. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de> Acked-by: Álvaro Fernández Rojas <noltari@gmail.com>

+Subject: [PATCH] gpio: Enable nonexclusive gpiods from DT nodes
+
+commit ec757001c818c175e6b610e8ef80c2a25d1ed1a5 upstream.
+
+This makes gpiod_get_from_of_node() respect the
+GPIOD_FLAGS_BIT_NONEXCLUSIVE flag which is especially
+nice when getting regulator GPIOs right out of device
+tree nodes.
+
+Suggested-by: Marek Szyprowski <m.szyprowski@samsung.com>
+Fixes: b0ce7b29bfcd ("regulator/gpio: Allow nonexclusive GPIO access")
