| [ Upstream commit 090c4094574705b0afc7d37825cdc5d06f0e7e02 ] |
| |
| External clocks should be defined as zero-Hz clocks in the SoC .dtsi, |
| and overridden in the board .dts when present. |
| |
| Correct the clock rate of extal1 from 25 to 26 MHz, to match the crystal |
| oscillator present on the APE6-EVM board. |
| |
| Fixes: a76809a329d6ebae ("ARM: shmobile: r8a73a4: Common clock framework DT description") |
