2310780244 MIPS: ath79: Use a helper function to get system clock rates
The ath79 platform uses similar code to get the
rate of various clocks during init. Separate the
similar code into a new helper function and use
that to avoid code duplication.

09f5100a59 watchdog: ath79_wdt: get register base from platform device's resources
The ath79_wdt driver uses a fixed memory address
currently. Although this is working with each
currently supported SoCs, but this may change
in the future. Additionally, the driver includes
platform specific header files in order to be
able to get the memory base of the watchdog
device.

The patch adds a memory resource to the platform
device, and converts the driver to get the base
address of the watchdog device from that.

0f2ad9ed7c MIPS: ath79: use dynamically allocated watchdog device
Remove the static watchdog device variable and use
the 'platform_device_register_simple' helper to
allocate and register the device in one step.

This allows us to save a few bytes in the kernel image.

13992303fa MIPS: ath79: register UART for the QCA955X SoCs
Similarly to the preceding SoCs, the QCA955X SoCs
also have a built-in NS16650 compatible UART.
Register the platform device for that to make
it usable.

The AR933X SoCs does not have a 8250 compatible UART, they
are using a different UART core. Register a different platform

d4a67d9dc8 MIPS: Add initial support for the Atheros AR71XX/AR724X/AR931X SoCs
This patch adds initial support for various Atheros SoCs based on the
MIPS 24Kc core. The following models are supported at the moment:

  - AR7130
  - AR7141
  - AR7161
  - AR9130
  - AR9132
  - AR7240
  - AR7241
  - AR7242

The current patch contains minimal support only, but the resulting
kernel can boot into user-space with using of an initramfs image on
various boards which are using these SoCs. Support for more built-in
devices and individual boards will be implemented in further patches.
