Merge tag 'renesas-dt3-for-v3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/dt
From Simon Horman:
Third Round of Renesas ARM Based SoC DT Updates for v3.14
* r8a7791 (R-Car M2) and r8a7790 (R-Car H2) SoCSs
- Add SSI, QSPI and MSIOF clocks in device tree
r8a7791 (R-Car M2) based Koelsch and r8a7790 (R-Car H2) based Lager boards
- Remove reference DTS
- Specify external clock frequency in DT
- Sync non-reference DTS with referene DTS
- Add clocks to DTS
* r8a7740 (R-Mobile A1) based Armadillo board
- Add gpio-keys device
- Add PWM backlight enable GPIO
- Add PWM backlight power supply
* r8a73a0 (SH-Mobile AG5), r8a7740 (R-Mobile A1) and
r8a73a4 (SH-Mobile APE6) SoCs
- Specify PFC interrupts in DT
* tag 'renesas-dt3-for-v3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas: (72 commits)
