[PATCH 0/6] More updates for NS2 DT

[PATCH 0/6] More updates for NS2 DT

[Anup Patel]

This patchset primarily adds more DT nodes for NS2 SVK. It also does
minor update to arch/arm64/Kconfig.platforms and adds missing DT
bindings document for sp805 driver.

The patchset is based on v4.5-rc3 tag and is available in ns2_dt2_v1
branch of https://github.com/Broadcom/arm64-linux.git

All patches have been tested on Broadcom NS2 SVK.

Anup Patel (5):
  arm64: Select COMMON_CLK_IPROC, PINCTRL and GPIOLIB for iProc SoCs
  arm64: dts: Add SDHCI DT node for NS2
  arm64: dts: Add ARM SP804 timer DT nodes for NS2
  dt-bindings: watchdog: Add ARM SP805 DT bindings
  arm64: dts: Add ARM SP805 watchdog DT node for NS2

Ray Jui (1):
  arm64: dts: Add PCIe0 and PCIe4 DT nodes for NS2

[PATCH 1/6] arm64: Select COMMON_CLK_IPROC, PINCTRL and GPIOLIB for iProc SoCs

[Anup Patel]

We select COMMON_CLK_IPROC, PINCTRL, and GPIOLIB in arm64 Kconfig
for ARCH_BCM_IPROC so that we can use COMMON_CLK, PINCTRL and GPIOLIB
with iProc SoC drivers.

[PATCH 2/6] arm64: dts: Add SDHCI DT node for NS2

[Anup Patel]

The IPROC SDHCI driver works fine for SDIO 3.0 on NS2 so let's enable
it for NS2 SoC in NS2 DT.

Rob, we would probably want an Ack from you on this one, but should we
route this through an arm-soc pull request for Broadcom SoCs, or do you
want to pick it in your tree directly?

Thanks!
