Subject: ARM: dts: renesas: r8a73a4: Fix external clocks and clock rate
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=090c4094574705b0afc7d37825cdc5d06f0e7e02;p=linux.git

ARM: dts: renesas: r8a73a4: Fix external clocks and clock rate

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.
