[PATCH v2 0/3] ARCH_BCM2835 Kconfig changes

[Florian Fainelli]

This patch series updates a number of Kconfig entries such that enable
ARCH_BCM2835 guarantees that essential drivers are also enabled, saves a
lot of configuration and troubleshooting time for when they are not.

Changes in v2:

- used "default y" instead of "default ARCH_BCM2835" per Conor's
  suggestion
- added Stephen's ack to the clock driver

Florian Fainelli (3):
  mailbox: Make BCM2835_MBOX default to ARCH_BCM2835
  firmware: Default RASPBERRYPI_FIRMWARE to y
  clk: bcm: Make CLK_RASPBERRYPI default to RASPBERRYPI_FIRMWARE

[PATCH v2 1/3] mailbox: Make BCM2835_MBOX default to ARCH_BCM2835

[Florian Fainelli]

This driver is depended on by CONFIG_FIRMWARE_RASPBERRYPI which provides
a number of essential services, including but not limited to a Linux
common clock framework provider. Make sure that enable
CONFIG_ARCH_BCM2835 does enable the corresponding mailbox driver as
well.

[PATCH v2 2/3] firmware: Default RASPBERRYPI_FIRMWARE to y

[Florian Fainelli]

The firmware driver provides the communication interface for a number of
other essential drivers, including a clock provider. Having it the
default when enabling CONFIG_ARCH_BCM2835 ensures that we have a
provider for essential system functions.

[PATCH v2 3/3] clk: bcm: Make CLK_RASPBERRYPI default to RASPBERRYPI_FIRMWARE

[Florian Fainelli]

The clock driver is essential in providing clocks for UARTs and other
peripherals, make it enabled by default.
