bmips: add new target
This target has full device tree support, thus reducing the number of
patches needed for bcm63xx, in which there's a patch for every board.
The intention is to start with a minimal amount of downstream patches and
start upstreaming all of them.
Current status:
- Enabling EHCI/OHCI on BCM6358 causes a kernel panic.
- BCM63268 lacks Timer Clocks/Reset support.
- No PCI/PCIe drivers.
- No ethernet drivers.

BCM6358 allow overlaying different +functions onto the GPIO pins. It does not support configuring individual +pins but only whole groups. These groups may overlap, and still require +the directions to be set correctly in the GPIO register. In addition the +functions register controls other, not directly mux related functions. + +Signed-off-by: Jonas Gorski <jonas.gorski@gmail.com> +--- + drivers/pinctrl/bcm63xx/Kconfig | 8 + + drivers/pinctrl/bcm63xx/Makefile | 1 + + drivers/pinctrl/bcm63xx/pinctrl-bcm6358.c | 393 ++++++++++++++++++++++++++++++ + 3 files changed, 402 insertions(+) + create mode 100644 drivers/pinctrl/bcm63xx/pinctrl-bcm6358.c + +--- a/drivers/pinctrl/bcm63xx/Kconfig ++++ b/drivers/pinctrl/bcm63xx/Kconfig +@@ -8,3 +8,11 @@ config PINCTRL_BCM6328 + select PINCONF + select PINCTRL_BCM63XX + select GENERIC_PINCONF ++ ++config PINCTRL_BCM6358 ++ bool "BCM6358 pincontrol driver" ++ select PINMUX ++ select PINCONF ++ select PINCTRL_BCM63XX ++ select GENERIC_PINCONF ++ select MFD_SYSCON +--- a/drivers/pinctrl/bcm63xx/Makefile ++++ b/drivers/pinctrl/bcm63xx/Makefile +@@ -1,2 +1,3 @@ + obj-$(CONFIG_PINCTRL_BCM63XX) += pinctrl-bcm63xx.o + obj-$(CONFIG_PINCTRL_BCM6328) += pinctrl-bcm6328.o ++obj-$(CONFIG_PINCTRL_BCM6358) += pinctrl-bcm6358.o +--- /dev/null ++++ b/drivers/pinctrl/bcm63xx/pinctrl-bcm6358.c +@@ -0,0 +1,390 @@ ++/* ++ * This file is subject to the terms and conditions of the GNU General Public ++ * License.
